Here’s how to pre-order the new Apple MacBook Air M4

Apple’s new MacBook Air doesn’t try to reinvent the wheel: It still comes in 13- and 15-inch sizes, starts with 16GB of RAM and offers up to 18 hours of battery life. But a few spec bumps — headlined by the faster M4 chip — paired with a cheaper price tag could still make it worth a look if your older model is starting to show its age. Here’s everything you need to know about the M4 MacBook Air.

The 13-inch MacBook Air now starts at $999, while its 15-inch counterpart begins at $1,199. (Both cost $100 less than last year’s model.) They’re available for pre-order now, ahead of their March 12 ship date.

Apart from the new pricing, the marquee upgrade is the M4 chip. Although it isn’t a massive leap over the M3, it still makes the 2025 MacBook Air up to twice as fast as the M1 model. (You know it’s less than a generational breakthrough if Apple’s comparing it to its first in-house silicon from 2020.) The M4 silicon in this model has a 10-core CPU and up to a 10-core CPU.

The MacBook Air still starts with 16GB of RAM, but the top-tier configurations support up to 32GB — an increase from a maximum of 24GB in the M3 model. When combined with the faster processor, you should see a noticeable speed boost when upgrading from an M1 or (especially) an older Intel MacBook.

In a welcome change for those whose laptop does double duty as a desktop PC, you can now connect it to two external displays while still using the built-in one. Last year’s model only supported two with the MacBook lid closed or one with it open.

The new MacBook Air also adds Center Stage, Apple’s auto-centering camera feature, for the first time in the lineup. It’s paired with a 12MP camera, which should make your video calls and selfies look much sharper.

The last big upgrade is a cosmetic one. It now ships in sky blue, a light metallic color also found in the iPad Air and AirPods Max. It joins the carryovers midnight, starlight and silver.

Elsewhere, it still supports Apple Intelligence (if you’re into that), runs macOS Sequoia and has a pair of Thunderbolt / USB 4 ports.

Phillips expands its Roku TV range with a $1,300 65-inch OLED

Roku is continuing its relationship with Phillips, with the launch of a new cross-branded television. The Phillips OLED Roku TV is available starting today and retails starting at $1,299 online and in stores at Sam’s Club.

The 65-inch screen has a 4K UHD display and OLED technology, which has become pretty standard for a premium TV model. It’s also equipped with Dolby Vision IQ, which adjusts picture quality settings based on the current lighting setup. And this Phillips OLED Roku TV includes a potential audio upgrade with the addition of a built-in Dolby Atmos 2.1 speaker system. The announcement highlighted the screen’s gaming potential, with a native 120Hz refresh rate and AMD FreeSync Premium to prevent screen-tearing.

Roku started making its own brand of televisions last year with the Pro Series, but it’s also still maintaining collaborations with more established hardware manufacturers. The Phillips model will support all the latest Roku features, such as Backdrops.

Apple announces M3 Ultra—and says not every generation will see an “Ultra” chip

Apple’s first Mac Studio refresh in nearly two years is a welcome update, injecting fresh life into two computers that were still getting by with M2 chips. But the company took a bit of a strange approach to the update, giving an M4-series Max chip to the lower-end Studio but an M3 Ultra chip to the high-end model.

These processors are both performance upgrades from the M2 Max and M2 Ultra, and the M3 Ultra is so huge that it should have no trouble outrunning the M4 Max despite its slightly older CPU and GPU architecture. But it’s still a departure from past practice, where Apple would keep the Studio’s chip generation in lockstep.

CPU P/E-cores GPU cores RAM options Memory bandwidth
Apple M3 Ultra (low) 20/8 60 96/256GB 819.2GB/s
Apple M3 Ultra (high) 24/8 80 128GB/256GB/512GB 819.2GB/s
Apple M2 Ultra (high) 16/8 76 Up to 192GB 819.2GB/s
Apple M1 Ultra (high) 16/4 32 Up to 128GB 819.2GB/s

When asked why the high-end Mac Studio was getting an M3 Ultra chip instead of an M4 Ultra, Apple told us that not every chip generation will get an “Ultra” tier. This is, as far as I can recall, the first time that Apple has said anything like this in public.

AMD Radeon RX 9070 and 9070 XT review: Hitting NVIDIA where it hurts

AMD has finally done it. For years it’s tried to undercut NVIDIA with slightly cheaper, but less capable, video cards like the Radeon 6700 XT and 7900 XT. And sure, it’s still following that same strategy with the new Radeon 9070 and 9070 XT. This time around, though, AMD has produced far more capable hardware, especially when it comes to 4K and ray tracing performance. And there’s hope that it could finally catch up to NVIDIA’s DLSS AI upscaling with its new FidelityFX Super Resolution 4 (FSR4) technology.

These aren’t perfect video cards, to be clear. But for $549 and $599, the Radeon 9070 and 9070 XT are far more compelling than AMD’s previous lineup. That’s particularly true since the 9070 XT is $150 less than NVIDIA’s RTX 5070 Ti, and in our testing it’s sometimes faster than that card.

AMD still has to prove that it can catch up to NVIDIA’s DLSS, which has had several years to steadily improve its AI upscaling capabilities. In particular, AMD needs to match the performance of NVIDIA’s multi-frame generation in DLSS 4, which has led to some surprisingly high fps figures while testing the RTX 50-series GPUs. AMD’s Fluid Motion Frames technology is a start, but it’s not nearly enough at this point.

The Radeon RX 9070 and 9070 XT are AMD’s first RDNA 4 GPUs, a new platform sporting more powerful and efficient compute units, third-generation ray tracing accelerators and second-generation AI accelerators. There isn’t a huge technical difference between the two cards: The RX 9070 features 56 compute units, 56 ray accelerators and 112 AI accelerators, whereas the 9070 XT has eight more compute accelerators and 16 additional AI processors. The XT model is clocked slightly higher, as you’d expect, and it also draws more power (304W vs 220W). Notably, both cards also ship with 16GB of GDDR6 VRAM, whereas NVIDIA skimped a bit and only put 12GB of RAM in the $549 RTX 5070.

As I was comparing our XFX-built review units, though, it was practically impossible to tell the RX 9070 and 9070 XT apart without reading the fine print on their labels. This is fairly typical for AMD cards with XT variants, and it makes sense since they’re technically so similar. The XFX Swift GPUs I tested came in an elegant frost white case, with three large fans and surprisingly massive heatsinks. They’re both 3.5-slot cards, so they also take up more room than the RTX 5090, which is a dense two-slot beast.

Thanks to AMD’s efficient RDNA design, you also don’t need to rely on complex power dongles to drive these cards. They both take two PSU connections directly, and XFX recommends 800-watt power supplies at a minimum. That’s significantly higher than AMD’s minimum 650W spec though, so it could be that XFX is just trying to play it safe with its massive cooling setup. (If you’re planning to overclock these cards, though, you’ll likely want more than a mere 650W PSU.)

AMD Radeon RX 9070
Devindra Hardawar for Engadget

I knew AMD was onto something special when I learned the Radeon RX 9070 averaged 60 fps in Cyberpunk 2077 in 4K Ray Tracing Overdrive mode. Sure, it needed FSR 3 upscaling to get there, but it was still better than the 50 fps I saw on the Radeon 7900XT a few years ago. The game occasionally dipped below 60 fps, but it was still very playable. 1440p was much smoother overall, averaging 117 fps. The Radeon 9070 XT, meanwhile, averaged 68 fps in 4K and 130 fps in 1440p.

Sure, these numbers are far behind the raw figures from NVIDIA’s RTX 5070, which used the magic of multi-frame generation to deliver 115 fps in 4K with ray tracing and maxed out graphics. That card also hit 205 fps in 1440p. But as impressed as I was by the 5070, most of those frames were just meant to deliver the illusion of smoothness. During actual gameplay, I had a hard time seeing much slowdown with either Radeon card in 4K, and the difference between the NVIDIA card was practically erased in 1440p. Remember, fps figures aren’t the entire story, even though NVIDIA wants you to believe otherwise.

I kept that idea in mind as I tested FSR 4, which surprised me when it averaged around 20 fps less than FSR 3 in Call of Duty: Warzone on both GPUs. The Radeon 9070 XT reached 250 fps in 4K with FSR 3, cranked up graphics and frame generation, whereas it hit 229 fps in FSR 4. AMD tells me that’s no error, it’s to be expected since FSR 4’s AI upscaling is more focused on delivering higher quality graphics rather than a pure frame boost. I couldn’t really see a huge difference while dodging bullets in CoD, but I did notice that finer textures like chain-link fences looked a bit clearer in FSR 4. (I also saw a few random glitched textures, something that was common in DLSS upscaled games early on. They weren’t a major problem, but AMD clearly has to refine its upscaling model further.)

At the moment, enabling FSR 4 is a bit counter-intuitive as well. You have to turn it on in AMD’s driver software, and then flip on FSR 3.1 in a compatible game. Warzone also required a reboot to fully enable the feature, but the game didn’t prompt me to do so. And if you want frame generation, that’s another option that has to be toggled on outside of the game. Hopefully this process will be smoothed out over time, along with wider availability for FSR 4. In addition to Black Ops 6, it’s supported in the newly launched FragPunk, Civilization 7, Marvel Rivals and a handful of PlayStation 5 ports like the Spider-Man games. But it’s nowhere to be found in Avowed or Dragon Age: The Veilguard, where you’ll be stuck with FSR 3.

AMD Radeon RX 9070
Devindra Hardawar for Engadget

For games that don’t work with FSR at all, AMD’s Adrenaline software also has a “HYPR-RX” mode that enables features like Radeon Super Resolution upscaling (a separate driver-level technology) and AMD’s Fluid Motion Frames generation. Altogether, they led to me seeing 200 fps in Forza Horizon 5 using the RX 9070 XT in 4K with maxed out graphics settings, up from 85 fps natively. But again, those are just fps figures – AMD points out Radeon Super Resolution may not look as clear as FSR alternatives. (I didn’t notice any weirdness in Forza, but I may have been distracted by the beautiful racing vistas in Mexico.)

When it comes to benchmarks, the Radeon RX 9070 and 9070 XT hold their own against NVIDIA’s 5070 and 5070 Ti in most of 3DMark’s tests. In the Steel Nomad benchmark, the 9070 scored 1,100 points higher than the 5070, and the 9070 XT beat out the more expensive 5070 Ti by almost 3,000 points in Timespy Extreme. I was also surprised to see the RX 9070 scoring almost 2,000 points higher than the RTX 5070 in the Port Royal ray tracing benchmark. Previously, ray tracing of any kind was AMD’s Achilles heel.

Both of our XFX cards also stayed surprisingly cool during benchmarks and extended gaming sessions. They never went beyond 65C under load, and they typically idled below 40C. And since they never got very hot, I could barely hear their fans spinning up.

AMD Radeon RX 9070

On paper, both of AMD’s new GPUs are compelling alternatives to NVIDIA’s midrange cards for 1440p gamers who occasionally dabble in 4K. The RX 9070 XT is particularly interesting, since it’s noticeably faster and still comes in $150 less than the RTX 5070 Ti. But we’re also dealing with a chaotic time in the PC gaming world, where GPU stock can disappear quickly and prices can rocket up quickly.

If you can nab either Radeon card at their listed prices, they’ll be good deals. But it’s not worth overpaying by too much for now. It also remains to be seen how the Trump administration’s combative tariffs will affect pricing for PC hardware and electronics. Prices could easily jump by 20 percent or more to cover those costs.

While NVIDIA’s DLSS 4 technology is more mature and leads to higher interpolated frame rates, there’s also a good argument for going with AMD’s cards since they have 16GB of VRAM. They’ll be better suited to handling larger textures in games down the line, and there’s also the potential for FSR 4 to improve as well.

AMD Radeon RX 9070
Devindra Hardawar for Engadget

It’s clear now why AMD was focused on upgrading its mid-range Radeon cards first. There’s not much point competing with NVIDIA at the extreme high end, like it did with Radeon RX 7900 XT and XTX. It makes more sense to focus on cards people can actually buy. The Radeon 9070 and 9070 XT also solve many of the problems I’ve had with AMD’s GPUs in the past. They can go toe-to-toe with NVIDIA’s cards, they have better ray tracing support and finally, they have AI upscaling. It remains to be seen if AMD will actually build on the promise of those features, but these cards are a hopeful start.

Apple unveils the M4 MacBook Air with a price drop

Apple has introduced its latest update to the MacBook Air, bringing the M4 chip to its lightweight laptops at long last. Even though the Air lineup is getting more powerful, it’s also getting cheaper. The smaller base model of the M4 MacBook Air will retail at $999, down $100 from the previous starting price. Pre-orders begin today, and the machines will be available starting on March 12.

Last year’s Air models were quite good but didn’t do anything revolutionary, and the same seems true for the 2025 versions. There are still two size choices, 13-inch and 15-inch. RAM for the M2 and M3 laptops is 16GB by default, and the M4 model matches that standard. Apple is promising up to 18 hours of battery life, and the Airs will have support for Apple Intelligence. There’s also a new look in the lineup, with the addition of a sky blue color to the now-familiar choices of silver, midnight and starlight. 

The company’s current chip has been available in MacBook Pros, the Mac mini and the iMac for awhile now, so the power levels of the M4 have been pretty well established. But the boost for Apple’s ultralights is still welcome. Apple says the new chip can make the latest Airs up to twice as fast as the M1 versions. The M4 is kitted out with a 10-core CPU and a GPU with up to 10 cores. It supports up to 32GB of unified memory.

The new prices might be the most exciting part of today’s Air announcements. The 13-inch M4 Air starts at $999, or $899 for buyers in education, while the 15-inch model starts at $1,199, or $1,099 for education.

Apple intros new Mac Studio models with M4 Max and… M3 Ultra?

Apple announced its first Mac Studio updates in nearly two years today, a few months after bringing the M4 and M4 Pro chips to the Mac mini.

As before, Apple offers a lower-end and a higher-end configuration of the Mac Studio. The lower-end model is pretty much what you expect: It gives you the same M4 Max processor Apple introduced in the high-end MacBook Pro last year. It has up to 16 CPU cores (10 P-cores, 4 E-cores), up to 40 GPU cores, and a 16-core Neural Engine.

The $1,999 base model comes with 14 CPU cores (10 P-cores, 4 E-cores), 32 GPU cores, 36GB of RAM, and 512GB of storage. That model’s RAM can’t be upgraded until you step up to the fully-enabled M4 Max, which also gets you 48GB of RAM for $300. From there, the desktop can be upgraded with either 64GB or 128GB of RAM, same as the MacBook Pro.

Apple’s new Mac Studio comes with the long-awaited M3 Ultra chip

Apple just unveiled its latest Mac Studio desktop PC promising improved performance over the previous model thanks to the long awaited M3 Ultra, the company’s highest performing processor to date. The new machine is primarily aimed at content creators, so on top of the faster chips, it offers the latest high-speed SSD storage, Thunderbolt 5 technology and an updated Neural Engine. 

It’s been a bit of a wait for a new Mac Studio as the last one came out at WWDC 2023, nearly two years ago. As before, you can think of it as like a “Mac mini Pro,” a bigger and significantly more powerful version of Apple’s budget desktop. Like the last two models, it comes in two configurations with either the M3 Ultra or M4 Max chips and physically looks the same as the previous M2 model.

Apple

The M4 Max version is aimed at “video editors, colorists, developers, engineers, photographers and creative pros,” according to Apple. To that end, it comes with up to a 16-core CPU and 40-core GPU, from 36GB to 128GB of RAM, four Thunderbolt 5 ports with 15 GB/s throughput (triple the previous model’s speed) and over 500 GB/s of unified memory bandwidth. It also includes Two USB-A ports (up to 5Gb/s), an HDMI port, 10Gb ethernet and a 3.5mm headphone jack. 

All that makes it up to 3.5 times faster than the original Mac Studio M1 Max. Apple noted that with the M4 Max chip, the latest Mac Studio is the first with Apple’s advanced graphics architecture that allows features like hardware-accelerated mesh rendering and a second-generation ray-tracing engine to boost content creation and gaming. For AI processing, it offers triple the speed of the M1 Max version.

The M3 Ultra model ups the ante considerably with a 32-core CPU with 24 performance cores, “50 percent more than any previous Ultra chip and the most CPU cores ever in a Mac,” Apple said. Meanwhile, the GPU packs up to 80 cores, another record for Apple silicon, along with a 32-core Neural Engine for on-device AI and machine learning. It also supports from 96GB to a record 512GB of unified memory, plus up to 16TB of SSD storage.

Apple

You may be wondering why Apple is just now releasing the M3 Ultra chip when every other Mac (including the all-new MacBook Air) has some kind of M4 processor. The answer is that it’s apparently not easy to design and build the Ultra processors because they’re effectively two chips mated together using Apple’s “Ultrafusion” bridge technology. Despite not having “M4” in the name, though, the M3 Ultra is still approximately twice as fast as the best M4 Max processor under taxing workloads and 2.5 times quicker than the Mac Ultra M1, according to Apple.

Considering its power, the Mac Studio with an M4 Max chip is reasonably priced starting at $1,999 with 32GB of memory and 512GB of storage. The Mac Studio with M3 Ultra is another story, though, doubling that to $3,999 base, with 96GB of unified memory (up from 64GB before) and 1TB of storage. Orders are now open with shipping set to start on March 12th.

MacBook Air gets the M4, a new blue color, up to 32GB of RAM, and a $100 price cut

As expected, Apple has officially refreshed its MacBook Air lineup with its M4 chip, the same silicon we’ve already seen in products like the MacBook Pro, the iMac, and the Mac mini. And in most ways, it’s a straightforward update, with no major changes to the laptop’s physical design, screen specs, keyboard, or ports.

The most important update is the price. The 13-inch M4 MacBook Air will start at $999, a $100 price cut compared to the M3 Air and the same price that Apple set for the M2 Air last year when the M3 models came out. The 15-inch model will also get a $100 cut, from $1,299 to $1,199. These baseline configurations still come with 16GB of RAM and 256GB of storage.

The M2 version will continue to be sold as a budget model in some countries, but the US isn’t one of them. Apple will also continue to sell a cheaper version of the M1 MacBook Air through Walmart, which it has been doing since March 2024.

Turing Award Winners Sound Alarm on Hasty AI Deployment

Reinforcement learning pioneers Andrew Barto and Richard Sutton have warned against the unsafe deployment of AI systems [alternative source] after winning computing’s prestigious $1 million Turing Award Wednesday. “Releasing software to millions of people without safeguards is not good engineering practice,” said Barto, professor emeritus at the University of Massachusetts, comparing it to testing a bridge by having people use it.

Barto and Sutton developed reinforcement learning in the 1980s, inspired by psychological studies of human learning. The technique, which rewards AI systems for desired behaviors, has become fundamental to advances at OpenAI and Google. Sutton, a University of Alberta professor and former DeepMind researcher, dismissed tech companies’ artificial general intelligence narrative as “hype.”

Both laureates also criticized President Trump’s proposed cuts to federal research funding, with Barto calling it “wrong and a tragedy” that would eliminate opportunities for exploratory research like their early work.

Anker charging gear is up to 35 percent off right now

Anker’s latest sale has brought prices down on a number of power banks and wireless charging gear. One of the best discounts of the bunch is 35 percent off the Anker 621 magnetic power bank, bringing it down to $26. The discount applies to all color options, too, so you can choose the one that best matches your personality. You can pick this one up either at Amazon or from Anker direct.

This model is MagSafe-compatible, meaning it’ll attach magnetically to an iPhone 12 and above (but, annoyingly, not the new iPhone 16e unless you resort to a workaround) and charge your phone wirelessly. However, if you plug a cable into the Anker 621’s USB-C port, you can top up your phone’s battery a little faster — at a rate of 12W vs. 7.5W for wireless charging. The power bank has a capacity of 5,000mAh, which Anker says is enough to charge an iPhone 15 to 85 percent of its capacity from zero and an iPhone 14 to 80 percent.

Anker makes some of the best power banks and best portable chargers around, in our opinion. There are lots of options to consider as part of this sale.

A new power bank that Anker introduced at CES has a large enough capacity to top up an M3-powered MacBook Air’s battery approximately 1.3 times, per the brand. This model has dropped by 18 percent from $110 to $90. This particular power bank can charge four devices simultaneously — it has two built-in USB-C cables, another USB-C port and a USB-A port. It supports fast charging at up to 100W as well.

Elsewhere, a 3-in-1 charging cube is down to $104, which marks a 31 percent discount given that it usually costs $150. This compact device can charge your iPhone, Apple Watch and AirPods at the same time.

There are a few other deals that caught our eye. An Anker Zolo power bank with a built-in USB-C cable is just $13, which is half off. It has a capacity of 10,000mAh, which Anker says is enough to fully charge an iPhone 15 Pro twice over. Meanwhile, Prime members can pick up a travel-friendly 3-in-1 charging station (that can top up your iPhone, Apple Watch and AirPods batteries simultaneously) for $88, which is a $21 discount.

Court denies Elon Musk’s attempt to block OpenAI’s for-profit transformation

US federal judge Yvonne Gonzalez Rogers has denied Elon Musk’s request for an injunction that would have immediately stopped OpenAI’s conversion into a for-profit entity. Musk filed for an injunction late last year after suing OpenAI and Microsoft and accusing them of telling investors not to fund rival AI companies, such as his own xAI. According to the Financial Times, the judge dismissed his request based on that claim of anticompetitive behavior. Gonzalez Rogers cited a previous statement by OpenAI CEO Sam Altman, saying that the company only warned certain investors who were granted access to sensitive information that their rights would be terminated if they made a non-passive investment in rival companies. 

The judge also reportedly rejected the request based on Musk’s claim that OpenAI and Altman broke their contract with him and violated the company’s founding mission of building AI “for the benefit of humanity.” Musk, who helped found OpenAI and funded it when it was just starting out, said Altman and his fellow OpenAI co-founder Greg Brockman “took advantage of [his] altruism in order to lure him into funding the venture.” In a statement sent to Bloomberg, OpenAI said that the lawsuit has “always been about the competition.” The company added that “Elon’s own emails show that he wanted to merge a for-profit OpenAI into Tesla. That would have been great for his personal benefit, but not for [OpenAI’s] mission or US interests.” 

After Musk filed his original lawsuit against OpenAI last year, the company published old emails between Musk and other people in the company. OpenAI revealed that Musk was not only aware that it was taking the for-profit route, he wanted majority equity, control of the initial board of directors and the CEO position. Anoter email from Musk suggested making the organization a part of Tesla. In February this year, Musk launched a bid to buy OpenAI for $97.4 billion, but the company gave him a firm “no thank you” in response.

As Bloomberg noted, the judge’s rejection of Musk’s request is significant, because OpenAI is already in the process of talking with government officials about taking on a more typical corporate structure. While the judge has rejected Musk’s request, she is fast-tracking his lawsuit and will hold an expedited trial later this year on the basis of public interest and on his claim that OpenAI’s transformation has a “potential for harm if a conversion contrary to law occurred.”

The 7 best cordless vacuums for 2025

Old-school, upright vacuums left a lot to be desired, and cordless models are here to right many of those wrongs. These types of vacuums tend to be thinner, lighter and easy to maneuver around a home, and you don’t really have to sacrifice suction power anymore to get those benefits. Dyson isn’t your only option anymore either — like the robot vacuum space, there are dozens of cordless vacuums to choose from today.

Variety is great, but it can also lead to decision fatigue and confusion. We at Engadget can help make that decision a bit easier. After testing a bunch of the best cordless stick vacuums available today, we’ve come up with our top picks, plus loads of buying advice to help you figure out which is the best cordless vacuum for you.

Most of the cordless models you’ll find today have stick designs, with a handle at the top attached to a debris bin, which has a space to connect different attachments at one end. These designs are more versatile than old-school, upright vacuums of yesteryear because, while you may use the long stick attachment most of the time to clean your floors, many cordless vacuums come with other attachments as well. Some allow you to clean hard to reach spaces like the interior of your car, while others make it easier to vacuum furniture and clean inside crevices.

Bin volume is worth keeping in mind when you’re choosing a cordless vacuum. The larger the bin, the more debris it can hold, but it might also mean a heavier machine. All of the cordless vacuums we tested had a bin size between 0.1 and 0.8 gallons and all were able to handle cleaning an entire one-pet home (roughly 2,000 square feet) in a single run without needing to be emptied. Anything smaller and you may have to deal with more frequent emptying during each cleaning session.

Some cordless models also have removable, replaceable battery packs, which is super handy. That means you can buy a replacement battery and install it easily, without needing to seek out professional assistance. Also, these extra batteries cost around $150-$200 a pop — expensive, yes, but nowhere near as costly as buying a whole new cordless vacuum.

Cordless vacuum suction power is typically measured in air wattage (AW), but you’ll see some that list the power of the motor in wattage (W) instead. Typically the higher the air or motor wattage the stronger the suction power, offering improved cleaning performance. And often strength is proportional to price — more expensive cordless vacuums tend to have stronger suction power. A general rule of thumb is that those with precocious pets or mess-making children would benefit from a cordless vacuum cleaner with stronger-than-average suction power.

Most cordless stick vacuums will have two different power modes: a “normal” or default power mode that balances suction power with battery life, as well as a “max” or stronger mode that kicks suction strength up a notch. Some vacuums, like those from Dyson, also have an “eco” mode, or one that prioritizes run time over strength.

Separate from power modes you can select yourself, some cordless vacuums will automatically adjust motor strength depending on the detected floor type or the amount of mess in its wake. This not only improves ease of use but ensures the vacuum is working as efficiently as possible.

The best cordless vacuums will be able to clean any standard floor type — hardwood, tile, carpet and everything in between. As mentioned previously, some can even detect floor type and adjust suction power accordingly. That said, it’s still worth thinking about the types of flooring you have in your home. If you primarily have carpet, you may want to consider a cordless vacuum with the most powerful suction you can afford, since there are more nooks and crannies for debris to get suck in with carpet.

Obviously, battery life is important since you’ll probably want to clean more than one room in a shot. All of the cordless vacuums we tested had a battery life of at least 40 minutes in standard cleaning mode. I tested each by cleaning all three floors of my home (upstairs, downstairs and basement) on a single charge with the machine running in its standard (“auto”) mode and none of them ran out of juice before I could finish the third floor. That said, extra battery life can come in handy if you’re switching between power modes since “max” or high-power programs use more energy.

Most cordless stick vacuums come with some sort of base or mount where the machine lives when you’re not using it. Wall mounts are the most common, but some have free-standing bases where you dock and charge the vacuum. Consider the space in your home where you want the cordless vacuum to live, since it will have to have an outlet or another power source nearby.

Some high-end cordless vacuums come with self-emptying bases that act much like those included with expensive robot vacuums. After cleaning and returning the vacuum to the base, it will automatically empty the dustbin into a larger dustbin that you can then detach from the base when you need to empty it. This is great for anyone concerned about allergens, as you’ll only need to empty the larger dustbin every month or two, reducing your contact with dust and debris.

Yes, some cordless vacuums have “smart” features like Wi-Fi and app connectivity. But before we get into those, let’s talk about the extra perks scattered among these devices. Some models, like the latest from Dyson, include particle sensors that show you how many different sized pieces of debris it’s sucking up in real time. Dyson’s, for example, is a piezo acoustic sensor that detects particle size and frequency and displays that information on the vac’s LCD screen. Tineco’s iLoop sensor is similar, controlling its vacuums’ automatic suction power adjustment and changing a circle on the display from red to blue as you fully clean an area.

Higher-end cordless vacuums may also have companion apps that show things like battery level, filter status and cleaning logs. It’s an added level of convenience, but by no means necessary. Unlike the best robot vacuums, or even the best budget robot vacuums, which rely on their apps to set cleaning schedules, manually control the machines and more, cordless vacuums that you operate yourself really don’t need Wi-Fi or an app connectivity.

Cordless stick vacuums range in price from $150 all the way up to over $1,000. The best ones for most people lie in the middle, in the $400 to $700 range. You’ll notice most of our picks land in the higher end of that range, but for good reason: More expensive machines tend to have more sucking power, which means less time wasted going over the same spots over and over. But does that mean everyone needs the most premium cordless vacuum? Definitely not. We’ve come up with top picks at various price points that should work well for people with different budgets, lifestyles, home sizes and more.

Engadget doesn’t have a dedicated lab in which we can test cordless vacuums, but I used each model in my home for weeks. I ran them over hardwood and tile flooring, as well as low-pile carpet. And my first runthrough consisted of cleaning all three floors of my home on a single battery charge. I performed the same cleaning job as many times as possible, but also intermittently cleaned a single floor as needed, or sucked up isolated messes like crumbs, cat litter spills and tufts of pet fur. Over the course of many cleanings with each model, I made note of how loud the machine was, how easy it was to maneuver around my home, how easily it sucked up pieces of large debris (or if it pushed it around my floor instead) and if they got warm or hot.

The Dyson Gen 5 Detect has a single-button start and stronger suction power than our top pick, but it’s otherwise quite similar. However, since the Gen 5 Detect is more expensive at $950 (although it does receive discounts at Dyson online), the V15 Detect still provides greater value for your money. The Gen 5 Detect is arguably best for those who want the latest Dyson, or care about getting a more future-proof machine, since it came out just last year.

The Shark Detect Pro provides a lot of value for the money, but it was ultimately beat by the Tineco Pure One S15 Pet for our runner-up slot thanks to the Tineco’s stronger suction power. The kicker for the Detect Pro is that it includes a self-emptying base in its $450 price, which is super handy. It’ll automatically dump the contents of the vacuum into the larger bin in the base after every cleaning, and you only need to empty the base’s container every month or so. The Detect Pro did a good job cleaning up messes across different types of flooring, and it’ll auto-adjust suction power depending on the amount of debris and whether you’re cleaning hard or carpeted floors. However, it’s not as smooth to use as any of our top picks and its main cleaner head is a bit tall, making it difficult to use to clean under low furniture.

Most cordless vacuums will run for at least 30-40 minutes on a single charge, but you can find cordless vacuums with battery lives of up to 60 or 70 minutes. Manufacturers will outline an estimated battery life for each model, and they’re usually based on using the vacuum’s standard power mode for the entire runtime; if you switch between modes or prefer to use a higher-powered program for improved suction, you’ll drain the battery faster.

Cordless vacuums do sacrifice a bit in overall power when compared to corded models, but that doesn’t mean they can’t handle everyday messes just as well. If suction power is your biggest concern, we recommend springing for a high-powered, high-end cordless vacuum since, typically, the more expensive a cordless vacuum is, the stronger the suction. Also, cordless vacuums have the edge over corded models when it comes to weight and convenience: cordless vacuums are much lighter than their corded counterparts, and you’ll never have to worry about placement or picking a fight with a cord while cleaning your living room.

Yes, cordless vacuums can handle pet hair well, but we recommend getting a model with strong suction power to get the best results. It’s also wise to get one with a larger bin, since pet hair can quickly fill up smaller bins, which may force you to stop cleaning to empty the vacuum before finishing.

Maintaining a cordless vacuum is super easy and helps to keep it running like new. First, make sure to empty the dustbin regularly — don’t let it overfill, as this can impact suction. Many models have washable filters, so rinse them out every few weeks (check your manual for specifics) and let them dry completely before putting them back.

Next, take a look at the brush roll — hair and debris can get tangled up in there over time. Most vacuums make it simple to remove the brush roll, so you can snip away any tangles with scissors. If your vacuum has a replaceable battery, try not to let it fully drain too often, as this can reduce its lifespan. A quick wipe-down of the vacuum’s exterior and attachments will also keep everything looking fresh.

Lastly, keep an eye on the sensors and charging contacts, as dust can build up there too. A gentle wipe with a dry cloth every now and then will do the trick.

Cordless vacuums are surprisingly versatile, and many come with attachments specifically designed for surfaces like curtains, upholstery and even mattresses. A handheld vacuum mode, which is common in cordless models, makes it easy to tackle these areas. Look for a soft brush or an upholstery tool in the attachments for the vacuum you’re considering — it’ll help remove dust and pet hair without damaging fabrics. For curtains, it’s a good idea to use a lower suction setting if your vacuum has adjustable modes. This prevents the fabric from getting pulled into the nozzle.

NASA Uses GPS On the Moon For the First Time

An anonymous reader quotes a report from Popular Science: On March 2, Firefly Aerospace’s Blue Ghost made history, becoming the first commercial lunar lander to successfully touchdown on the moon’s surface. The groundbreaking lander is wasting no time in getting to work. According to NASA, the joint public-private mission has already successfully demonstrated the ability to use Earth-based GPS signals on the lunar surface, marking a major step ahead of future Artemis missions. Accurate and reliable navigation will be vital for future astronauts as they travel across the moon, but traditional GPS tools aren’t much good when you’re around 225,000 miles from Earth. One solution could be transmitting data from the Global Navigation Satellite System (GNSS) to the lunar surface in order to autonomously measure time, velocity, and position. That’s what mission engineers from NASA and the Italian Space Agency hoped to demonstrate through the Lunar GNSS Receiver Experiment (LuGRE), one of the 10 projects packed aboard Blue Ghost. […]

“On Earth we can use GNSS signals to navigate in everything from smartphones to airplanes,” Kevin Coggins, deputy associate administrator for NASA’s SCaN (Space Communications and Navigation) Program, said in a statement. “Now, LuGRE shows us that we can successfully acquire and track GNSS signals at the Moon.” LuGRE relied on two GNSS constellations, GPS and Galileo, which triangulate positioning based on dozens of medium Earth orbit satellites that provide real-time tracking data. It performed its navigational fix at approximately 2 a.m. EST on March 3, while about 225,000 miles from Earth. Blue Ghost’s LuGRE system will continue collecting information over the next two weeks almost continuously while the lander’s other tools begin their own experiments.
