The company has added two university campuses in California and Utah. A day after hitting its pediatric enrollment goal, Spectral AI has expanded the scope of its pivotal burn study by adding two more clinical trial sites in the US.
The addition of UC San Diego and the University of Utah brings the total number of US clinical trial sites to 14.
The pivotal study (NCT06131203) is evaluating the US company’s AI wound diagnostic platform DeepView.
“These two new sites allow us to accept more burn patients coming in through the emergency room, complementing our existing trial sites in burn centers across the country, establishing our presence in new regions, and advancing our goal of completing this study by the end of the year,” said Peter Carlson, CEO of Spectral AI.
Expanding the clinical trial base allows access to a more diverse patient population and reduces bias, Carlson added. This is particularly important for imaging devices, where skin color and patient anatomy can affect outcomes. DeepView uses algorithms to analyze multispectral imaging of wounds against a database of burn biopsies. Spectral AIsays the device can help predict wound healing outcomes and support clinical decision making. Early assessment of the depth and severity of burns is critical to ensuring that patients receive appropriate care. According to analysis by GlobalData, the wound care management market is expected to reach a total of $38.8 billion by 2030, with a compound annual growth rate of 3.4%.
In addition to spectral imaging, lasers, optical cameras, and photoacoustic imaging are also used to assess burn depth.
Spectral AI, formerly known as Spectral MD, changed its name after a business combination with special purpose acquisition company (SPAC) Rosecliff Acquisition Corp I. The company’s technology was approved for adult use in the UK in February 2024 and is currently being evaluated in trials with a view to obtaining approval from the US Food and Drug Administration (FDA).
Spectral AI plans to complete the pivotal trial in the fourth quarter of 2024 and is expected to obtain approval in 2025.
In March 2024, the company signed contracts with the Defense Health Agency (DHA) and the US Army Medical Material Development Activity (USAMMDA). The goal of the funding is to support the development of a handheld version of its system for use by military personnel in the field.
Harman Kardon Esquire 2 review: A premium Bluetooth speaker at a great price
The Esquire 2 is where the premium lifestyle brand comes in to the overcrowded Bluetooth market. For most brands, standing out is hard, but the Harman Kardon Esquire 2 is different. It’s a premium Bluetooth speaker from a luxury brand that doesn’t come cheap. But is it all about looks and premium feel, or does it actually perform well in terms of sound quality? Let’s find out. Build and Design: 9/10 The Harman Kardon Esquire 2 is a well-designed speaker. Like all Harman Kardon designs, it looks simple, sophisticated, and refined.
It has a solid plastic grille on the front and a leatherette back, from which the kickstand pops out. The speaker is surrounded by an aluminum finish, with indicator lights on the left and action buttons on the top.
harman-kardon-esquire-2-backThe Esquire 2 weighs just 600 grams and is slightly taller than a clutch. In fact, it doesn’t look like a speaker in the traditional sense at all.
harman-kardon-esquire-2 frontThe top control buttons are minimal and useful, and they also double as buttons for playing and pausing music.
harman-kardon-esquire-2-topThe right side of the device has a microUSB charging port, an auxiliary 3.5mm jack, and a regular USB port, so you can use it to charge your smartphone or tablet. Very nice! harman-kardon-esquire-2-USB connectionsThe Premium Skimp Esquire 2 undoubtedly packs a lot of surprises, the biggest of which is that despite its high price, there are virtually no accessories. There’s just a flat USB cable in the box, and that’s it. There’s no charger, no auxiliary cable, and no bag to carry the speaker in (the bag is sold separately). A device that costs less than half the price comes with more accessories than Harman Kardon’s Esquire 2.Performance: 9/10 We tested the Esquire 2 with an Android phone connected to a Windows PC via Bluetooth via a 3.5mm auxiliary cable.
Overall, these are excellent Bluetooth speakers, and they get surprisingly loud without feeling like they’re trying too hard. Sure, we’ve heard louder sound from the larger Bose Sound dock V2 portable speaker, but for its size, the Esquire 2 performs very well. The complaint most people have about Bluetooth speakers is that they usually sound mono because there’s only one speaker in such a small box. The Harman Kardon Esquire 2 solves this problem by actually inserting four different “professionally tuned” sound drivers and a passive radiator (reflex port) into the box instead of two. The resulting sound is satisfyingly rich stereo, rather than the cramped mono sound that most Bluetooth speakers produce.
You’ll notice that the speaker handles bass very well. No matter which track I played, the Esquire 2 handled the sound very well. Of course, the speaker does lack extreme low-end bass, which was evident in Charlie Puth’s Betty Boop (Original Mix), which gives the bass very deep and can really give any speaker a workout. Surprisingly, the Esquire 2 handled this track very well. Most Bluetooth speakers can’t produce sub-bass at all, and neither can the Esquire 2, but what the Esquire 2 produces is rich bass while playing tracks loudly without gasping for air. All the music played is full and layered. While you’ll definitely hear round and rich bass and low-mids, the mids and highs are no slouch either. The highs and mids are crisp, bright, and prominent. The vocals sound especially good, with the Aventine track by Agnes Obel especially highlighting the singer’s voice, and the violin score is also very beautiful, with a full and rounded sound. Call Quality: 9/10 Call quality is excellent, with voices loud and clear, although the other party may experience a hollow or “speaking through a tube” effect, which is a problem with all Bluetooth speakers. With the “quad mics”, the speaker can easily capture sounds from all directions without a problem, and it’s obvious that the Esquire 2 is designed for conference calls.
Harman Kardon Esquire 2 Battery
: 8.5/10Battery life is up to 8 hours, and it takes quite a while to fully charge the 3200 mAh rechargeable battery. While 8 hours is plenty in most cases, Harman Kardon could have inserted a larger Harman Kardon battery, such as a 5000 mAh, since phones like the Asus Zenfone Max are now equipped with larger Harman Kardon Esquire 2 Batterywithout significantly increasing the weight. If price is no object, and you like truly premium sound, a small portable device, and a powerful voice conferencing system, try the Harman Kardon Esquire 2; you won’t be disappointed.

Panasonic’s ‘new’ Lumix FZ80D is a 60x superzoom camera
Designed primarily for wildlife and nature photographers, the original FZ80 was launched back in 2017. The new FZ80D offers minor upgrades across the board, but retains the all-important 60x zoom lens. The Panasonic FZ80D’s imaging capabilities are identical to the standard FZ80. The camera features a small 18.1-megapixel 1/2.3-type image sensor and a 20-1200mm equivalent lens. Maximum aperture range is f/2.8 to f/5.9.
Other features include RAW image recording, 4K/30p video, optical image stabilization, and continuous shooting up to 10 frames per second. ISO ranges from 800 to 3,200.
Even after seven years, the FZ80D doesn’t bring many changes or improvements. Panasonic improved the electronic viewfinder, increasing it from 1.16 million dots to 2.36 million dots, a gain of about 50%. The rear LCD is also sharper, increasing from 1.04 million dots to 1.84 million dots. The new FZ80D model also features a USB-C port instead of the old-school micro USB of the old model.
Granted, the FZ80D’s small 18.1-megapixel image sensor isn’t stellar, especially at higher ISO settings. The 20-1200mm equivalent zoom lens isn’t sharp at any extreme, but the FZ80 (and now the FZ80D) enables photographers to take photos that would be difficult or expensive to capture using an interchangeable lens camera system.

Aorus 15 XE5 review: A compact QHD gaming laptop with Thunderbolt 4
Energy guzzler. With the Aorus 15 XE5, Gigabyte has introduced another 15.6-inch compact gaming notebook to the market. Among other things, this laptop shines with its impressive performance (both in gaming and non-gaming applications) and its ability to accommodate two PCIe 4.0 SSDs. The Gigabyte Aorus 15 XE5 features a black plastic chassis with a smooth, matte finish. There are no extravagant design elements to the device. The thin bezels around the display add an elegant touch to the laptop. The laptop’s design is further accentuated by the illuminated Aorus logo on the back of the lid. Once you remove the bottom panel, you can get a peek at the battery (screwed on, not glued on) and the rest of the internals. Keyboard
This gaming laptop comes with a chiclet keyboard with a number pad. The smooth keys offer a moderate travel distance and a distinct actuation point. The keyboard does not flex while typing. Each key is individually illuminated and has two brightness levels. Overall, Gigabyte has offered a keyboard that is suitable for everyday use. Performance – Plenty of power thanks to Alder Lake and AmpereThe Gigabyte Aorus 15 XE5 is a powerful 15.6-inch laptop that performs well in a variety of demanding usage scenarios. In addition to the review configuration, Gigabyte also offers two other models: one with an RTX 3080 Ti laptop (Aorus 15 YE5) and another with an RTX 3060 laptop (Aorus 15 KE5).
ProcessorThe Core i7-12700H processor (Alder Lake) contains six performance cores (Hyper-Threading, 2.4 to 4.7 GHz) and eight efficiency cores (no Hyper-Threading, 1.8 to 3.5 GHz), for a total of 20 logical CPU cores.
When the laptop is powered by Gigabyte Aorus 15 XE5 Laptop battery
power, the clock speed is significantly reduced. Overall, the Core i7 in the Aorus 15 XE5 delivered slightly above average benchmark results. Power Management – The XE5 requires too much powerGigabyte Aorus 15 XE5 Laptop
Energy ConsumptionThe Aorus 15 XE5 consumes too much power when idle, consuming around 31 to 46 watts, sometimes even up to 80 watts in the worst cases. Comparing the XE5 to its competitors gives a rough idea of how much power an Optimus-enabled laptop should consume when idle. This high power consumption is likely due to a bug. The problem persists even when disabling the AI Boost feature. So we’ll have to wait and see if Gigabyte is able to fix this with software or a BIOS update.
Throughout the stress test and The Witcher 3 test, the laptop’s power consumption remained stable and at a level that’s normal for the hardware. The included charger has more than enough capacity to power the laptop and was able to handle momentary spikes that exceeded its output rating (240 watts).

Microsoft Surface Go review: The ultimate task-processing tablet
The Microsoft Surface Go has it all beat, and in the race for the ultimate small tablet, it’s a winner. This small tablet packs everything we loved about the Surface Pro 6 into a smaller, more affordable package.
While this tablet doesn’t surprise with a ton of new features, the Microsoft Surface Go still has a few aces up its sleeve. With Windows 10 S mode running out of the box, there’s no half-baked OS or weird app compatibility issues with this tablet. And with new OS updates and accessories, Microsoft Surface Go Tablets batteriesthistablet will only get better.
In essence, the Microsoft Surface Go is what the Surface 3 should have been, proving that a portable device can be one of the best Windows tablets while also being affordable for most people. And, depending on your workload, the Microsoft Surface Go might just be the perfect device for both your productivity and entertainment needs. The first big hint at the Surface Go’s target audience is the rather noticeable rounded corners and edges Microsoft has applied to the device. Gone are the angular edges of the Surface Pro, replaced with rounded, soft edges that help give this version of the Surface a unique identity.
Other than that, the design of the device is essentially the same as its predecessor, just in a smaller form factor. The excellent hinge bends nearly 180 degrees just like before, making this device an ideal canvas for digital drawing and note-taking. Microsoft’s Surface Go display is still top-notch. With a resolution of 1,800 x 1,200 pixels, it’s far from the sharpest 10-inch tablet display, with the latest iPad coming in at 2,048 x 1,536 pixels.
Still, the Microsoft Surface Go’s display is gorgeous for everyday use. The display is extremely color-accurate, and movies and photos look great on it. Of course, the 3:2 aspect ratio is great for work and web browsing, but full-screen 16:9 videos waste some space due to black bars. As with most tablets, the bezels around the screen are fairly large, but this only allows users to hold the device from either side without accidentally triggering anything on the screen. It also allows the Type Cover to attach to the bottom bezel via magnets for a better typing angle.
As for the relatively thick bezels, the Surface Go’s speakers are located on either side of the screen. For such small drivers, the speakers sound surprisingly powerful and deep, and they provide detailed channel separation. This makes the Surface Go both a great multimedia tablet and a lightweight productivity device.

Best Dell XPS 13 and 15 for July 2024
The latest addition to Dell’s XPS 13 and 15-inch lineup is a refreshed 13-inch model. While the older model is still easily available, this Dell XPS 13 2024 features the latest design and components – bringing it in line with Dell’s other new models (now available in 14-inch and 16-inch models).
Visually, the Dell XPS 13 2024 shares many of the same design features as the 2023 Dell XPS 13 Plus, namely the seamless trackpad, zero-grid keyboard, and a row of touch-enabled keys below the display. These modern touches give the model an overall more premium feel, even though the older model is still an ultra-premium laptop in its own right.
One of the more interesting changes to the Dell XPS 13 2024 is the inclusion of a new Intel Ultra series chipset. These are new processors from Intel that include an NPU, or “neural processing unit,” designed to enhance AI-assisted tasks. Beyond that, however, they’re mostly iterative improvements to overall performance and power efficiency.Dell XPS 13 Laptop battery.
We wouldn’t currently rank the latest Dell XPS 13 as a top choice for value, as it starts at a relatively high $1,399. In comparison, we’ve seen the slightly older XPS 13 Plus on sale for as low as $999 – a model that looks very similar to the latest model. The older XPS 13 model is still easily available for purchase, with the base Core i5 model available for as low as $599. The Dell XPS 13 Plus was a separate premium version of the XPS 13 that was originally released in 2023. It has been replaced by the latest 2024 XPS model, which inherits its design, but is still easily available on Dell’s official website – and often at a discount.
On the outside, this model is almost identical to the new base XPS 13, with a seamless tactile keyboard and a redesigned keyboard. However, its internal components are slightly older. Rather than featuring the latest ‘Ultra’ series processors, it comes with a standard Intel Core i7 chipset – which is still more than powerful enough for zipping through everyday tasks.
Generally speaking, we still recommend the Dell XPS 13 Plus if you can get it for a reasonable price. We’ve recently seen Dell offer the XPS 13 Plus for as low as $999/£898, which is a great deal considering it’s only been out for a year at the time of writing. It’ll likely be the cheaper option for a while compared to the standard 2024 XPS 13, and will be a great choice if you’re willing to give up the latest chipset. The older Dell XPS 13 from 2022 is still easily available as of early 2024, unofficially making it the ‘entry-level’ model. While it lacks some of the latest design features (like a fancy keyboard or trackpad-less design), it’s still a great Ultrabook and a current top pick if you’re looking for absolute value for money.
The 2022 XPS 13 features a 12th-generation Intel Core chipset, which is still a good choice if you’re not looking for cutting-edge performance. For example, if you just want a premium laptop for writing emails or watching videos on the go, then the Core i5 model might be a good choice. We’ve seen this base model on sale for just $599/£799, which is great value.
However, if you need more performance, then you might want to set your site on the Core i7 model – which also has a more spacious 512GB SSD. This particular model is available in the US for as low as $799, which we think is a great price as it’s still a very powerful laptop. This is the newest Dell XPS 15 on the market right now, as the 15-inch model hasn’t yet received a 2024 update like the 13-inch model. Although it’s not the newest model on the market (there’s now an XPS 16), it’s still a good choice right now if you want a powerful laptop that can take on the heaviest workloads.
In addition to the latest components from Intel and Nvidia, the latest Dell XPS 15 2023 includes the option to configure your machine with up to 64GB of RAM and a 4TB SSD, as well as the option of a luxurious 3.5K OLED display. As you can imagine, these specs come with a very high price, but we’re starting to see better deals on this 15-incher now that it’s no longer the latest model in the series.

Panasonic LUMIX GH4 officially released: ultra-complete 4K video recording, more powerful specifications and performance!
Panasonic today officially released the flagship LUMIX GH4 of its Micro 4/3 mirrorless camera series in Japan, replacing the GH3 that debuted in September 2012. Panasonic GH4 batteryThe new camera is based on the weatherproof and dustproof metal body of the GH3, but has many improvements, making it attractive to both still photography enthusiasts and multimedia videographers. The GH4 features an ultra-high-performance sensor and quad-core processor, which can provide better color interpretation, dynamic range and noise suppression, support 60-minute long exposure with B shutter, and achieve 4K ultra-high resolution video recording. In addition, its autofocus is faster and more accurate, and it also supports eye priority autofocus.
On the official website, Panasonic has released many GH4 photos and videos taken by professional photographers. Although the full resolution is not available yet, the color interpretation seems to be the highest level among LUMIX models. As for the launch information, Panasonic has not yet disclosed the release date and suggested retail price of GH4. It is generally expected that the body price will be around US$2,000, and the release time may be between March and May this year. New sensor + ultra-high-speed quad-core processor GH4 uses a new 16.05 million pixel digital Live MOS sensor, and through the greatly updated ultra-high-speed quad-core Venus processor, it can achieve 50% faster image signal readout than before, not only achieving 30fps 4K ultra-high resolution video recording, but also achieving full resolution 12fps efficiency in static continuous shooting, continuous shooting of 100 JPEG or 40 RAW format images, and continuous autofocus can still maintain a good efficiency of 7.7 frames per second. At the same time, with better noise suppression, ISO 25600 is officially listed as one of the standard sensitivity options (not the original extended setting), and can support B shutter mode exposure for up to 60 minutes. According to Panasonic, the GH4 has also been improved in terms of color interpretation and light and dark levels. In addition, due to the high-speed photosensitive element, the GH4 can significantly improve the jello phenomenon that may cause moving objects to appear distorted when recording dynamic videos or taking photos through the electronic shutter.
However, it should be noted that Panasonic’s official senior management revealed that because the GH4 was designed with great emphasis on internal heat dissipation, it does not have a body anti-shake like the GX7, but the new machine’s better noise suppression ability may make up for this regret.
The world’s first 4K mirrorless interchangeable lens digital cameraThe GH4 is the first mirrorless model that can support 4K video recording, but its 4K video recording is not just an experimental or demonstration-like paper talk, but has extremely complete demonstration-level specifications as soon as it appears. It offers two 4K resolutions: Cinema 4K (1:85:1, 4096×2160) and QFHD (16:9, 3840×2160), with a maximum refresh rate of 24FPS and 30FPS respectively, and two video formats: MOV (supports LPCM uncompressed audio) and MP4 (supports AAC audio), and 100Mbps traffic is encoded in IPB.
For the more basic 1080p video resolution, there is also a 200Mbps ALL-Intra encoding ultra-high traffic mode that can bring extremely clear image quality. In addition, it also supports 2fps, 96fps, 4X and other modes to achieve slow motion and fast motion videos, and can also produce time-lapse photography and stop-motion animation in the body.
Faster, more autofocus points, support for eye focusAccording to Panasonic, the autofocus capability of the GH4 is more advanced than other Panasonic models. Through the newly introduced DFD (Depth from Defocus) technology, the depth of field information of each Panasonic original lens at various aperture focal lengths is used as a calculation reference, further shortening the hesitation time when focusing, and achieving an ultra-high-speed AF of 0.07 seconds. In addition, the focus segmentation area of the GH4 has also been increased from 23 points of the GH3 to 49 points, and the face focus has been strengthened to a more detailed face focus. After finding the face in the picture, the eye area is the clearest range. As for the peak focus required for manual focus, this time the GH4 has of course also been added as expected.

Nikon D810 review: The ultimate adventure camera?
Last month, I took my Nikon D810 out into the Sierra Highlands—one of the toughest adventures. It got dirty, wet, and knocked around a lot. Here’s how it fared. The D810 has strong weather sealing, so it can handle wet or dusty conditions.
DurabilityDurability is arguably one of the most important factors when choosing a camera for adventure photography.
The D810’s body is made entirely of magnesium alloy (magnesium is the lightest structural metal) and is weather-sealed to keep rain and dust out of the camera’s interior. Its shutter is tested for 200,000 cycles, 25% more than the Canon 5D Mk III. All of these features come together to make for a rugged camera.
Nikon D810 Review: The Ultimate Adventure Nikon D810 Camera?
We took the brief but terrifying opportunity to shoot with the D810 in the rain. Photos by Gilberto Gil.
The camera also seems to do a good job of keeping out dust. Upon closer inspection of my photos, only a small dust spot showed up after a month of daily outdoor use and two weeks of intensive High Route shooting—acceptable given the conditions.
All of these factors combined have worked well together; so far, I can confidently shoot with the D810 no matter what difficult conditions I encounter on my adventures. Ease of Use
Nikon D810 Review: The Ultimate Adventure Camera?
The D810 is about twice the size and weight of Sony’s A7-series mirrorless cameras.
First, the D810 is big. The body alone weighs 31 ounces, which is heavy (but still comparable to a Canon 5D Mk III or 5Ds). Add a Nikon 24-70mm f/2.8G ED ($2,499) and the weight reaches 64 ounces, or 4 pounds. That’s too heavy to carry around your neck, in your hands, or, worst of all, in your backpack. Especially if you’re already carrying a lot of outdoor gear.
By comparison, the mirrorless full-frame Sony A7S and 16-35mm f/4 weigh only 34 ounces, or almost half that, and are much easier to handle.
Due to the size and weight of the D810, it’s not a good idea to carry it in the backcountry. Using a standard neck strap is cumbersome; it’s too bulky to use the Peak Design CapturePro clip. The best way I found to carry it was with a Peak Design Slide, but even that isn’t a perfect solution. This problem isn’t unique to the D810, however, but rather a problem with all SLRs; it’s only been highlighted by the recent emergence of more compact but still high-quality mirrorless cameras.
Nikon D810 Review: The Ultimate Adventure Camera?The number of shots remaining is displayed on the LCD screen even when the camera is off.
In my past experience with Nikon cameras, the user interface was a major downfall. It felt clunky, the buttons were hard to reach, and the placement made no sense. However, that’s not the case with the D810. The power switch is located around the shutter button, so you can turn it on and start shooting with just a flick of the wrist. With the default control map, the shutter speed dial is located on the (protruding) handgrip just below the shutter release button; the aperture adjustment dial is on the back of the camera where your thumb would be. The placement of these controls, plus the super-powerful Auto ISO mode, makes shooting in changing lighting conditions feel natural and intuitive.
Some nice touches on the D810 include a display showing the number of shots remaining on the card even when the camera is off, and an Auto Off mode by default. These are unremarkable but useful features. Shooting starts within half a second of turning the camera back on, allowing photographers to capture the briefest of moments.
The D810’s impressive dynamic range allows it to preserve detail in both highlights and shadows, even in challenging lighting conditions and environments – such as on snow. ISO 64, f/4.5, 1/160.
Speaking of capturing fleeting moments, the D810 borrows the renowned focus system from the top-of-the-line D4S, which features a 51-point Dynamic AF mode with 3D Tracking. Combined with a focus sensitivity of -2 to 19 EV, the camera locks onto subjects quickly and without hesitation, even in dark shooting conditions. When shooting on the highway, the D810 focused so quickly and quietly that I often didn’t even realize it had focused. The very fast and accurate focus system, combined with the respectable continuous shooting speed, makes it easy for the D810 to capture fleeting moments.

Eufy’s robot vacuums are small, affordable, and good-looking, but they’re a pain to navigate with their bounce. Eufy’s flagship ROBOVACS are among the most popular robot vacuums on the market. They’re small, good-looking, easy to use, and reasonably priced. I reviewed the 11+ in 2017, and its strengths almost outweighed its weaknesses… well, it didn’t clean very well.
This year, Eufy’s new 11S Max offers an upgrade to the same small, slim, and good-looking robot vacuum. Now, Eufy claims it has a maximum suction power of 2 kilopascals. (For comparison, the Coral vacuum has a suction power of 2.7 kilopascals; a typical handheld vacuum has a suction power of about 1.7 kilopascals.) When the vacuum’s brushes start to spin slowly on a high-pile carpet, they trigger the vacuum’s fan motor to increase suction. For such a small and light vacuum, it was very effective at agitating and cleaning my dog-hair-filled carpet.
My main gripe with the 11S Max is philosophical: It uses outdated navigation technology. Instead of mapping software, the 11S Max uses what’s called bounce navigation, which moves the robot randomly around your home until the battery runs out.
A few years ago, bounce technology was standard on cheap robot vacuums. Today, more affordable vacuums come with mapping software, which is a more efficient, thorough, and energy-efficient way to clean your house.
If your budget doesn’t exceed $200, the 11S Max is probably one of the best affordable robot vacuums you can buy. But if your budget is a little higher, you might want to research whether you can get a smart vacuum instead.
Desire to LiveThe 11S Max looks almost identical to the 11+. At 2.85 inches tall, it’s slim enough to fit under my couch, and there are no menacing red laser eyes or turrets sticking out of the glass top. To set it up, I plugged in the stand and placed the battery in the remote. The robot vacuum ran for an impressive two hours and lasted a little over four hours on a charge.
The dustbin capacity upgrade to 0.6 liters is respectable, and I filled it up with dog hair every time I used it. There’s no sensor to alert you when the dustbin is full, but Eufy says most people will probably only have to run the device two or three times to fill it up.
For a vacuum with such powerful suction, it’s remarkably quiet. I measured it at 60 decibels on hardwood and 60 to 65 decibels on carpet, depending on whether BoostIQ was enabled. For reference, 60 decibels is loud enough for me to watch the season finale of Fleabag while it cleans.
Infrared and drop sensors help the 11S Max navigate better than its predecessor. It deftly avoided steps in my kitchen and steered clear of robot traps like a kid’s scooter stacked in a corner.
In fact, the only household items that gave it serious trouble were dangling shoelaces from a shoe rack and a small decorative table with a domed base. The 11S Max spent so much time and energy hitting the angled sides of the table base that I ended up moving it to the garage while it vacuumed. My daughter’s long hair and I didn’t get tangled up with the carpet brush.
The 11S Max does have an edge cleaning feature, which combines random and edge cleaning paths if you set the vacuum to auto-clean. I did see it along some edges, like under my kitchen cabinets and along the wall. When the cabinet ended, however, it resumed bouncing merrily. I often found leftover crumbs in high-traffic areas of my home, like next to the shoe rack and under my kid’s chair at the kitchen table.
Against the AppFor some people, not having to download yet another app and fiddle with connecting a robot vacuum to your home network and your phone is a good thing. I certainly felt the same way when it came to Eufy’s Wi-Fi-free baby monitor. Sometimes it feels like a revelation to just plug in the device and use it.
There’s a button on the top of the 11S Max to power it on, but it also comes with a remote control that requires two AAA batteries. The remote features manual directional controls, as well as other features like boosting suction, returning it to the dock, and spot cleaning. You can also schedule cleanings with the remote, but only daily, not weekly or every other day like you can with Eufy’s Wi-Fi vacuums. Overall, the 11S Max is simple and easy to use. But I just couldn’t get over how outdated the bounce-clean feature was. I ran the 11S Max for a full two hours. When the Eufy RoboVac 11S Max vacuum’s battery finally started to die, it was in my bedroom.
