Sitting near the top of Roborock's product lineup, the Saros 10 ($1,599.99) is a premium robot vacuum and mop with just about every feature you could ask for. It offers several upgrades over Roborock's previous flagship, the Qrevo Curv ($1,599.99), including a boost in vacuum suction power, a slimmer design, and a retractable LiDAR navigation sensor that allows it to better fit under furniture. Though it offers some mopping upgrades, including an automatic detergent dispenser and the ability to detach its own mop for dry runs, it doesn't scrub as well as the Curv or some other high-end models with dual-spinning pads. The Ecovacs Deebot X8 Pro Omni ($1,299.99) offers comparable vacuuming performance and more effective mopping for less money than the Saros 10, so it remains our Editors’ Choice for premium robot floor cleaners.

Roborock Saros Series vs. Qrevo Series vs. S Series

Roborock offers a lot of robot vacuums, so its product lineup can be confusing. The Saros series is the brand's current top-tier offering, while its Qrevo and S series both include models that stretch from the midrange to premium end, and the Q series is its budget line.

At the top is the Saros Z70 ($1,899.99), slated to launch in early May. It has a retractable robot arm designed to pick up and put away objects like socks and toys. Below that are the Saros 10 and the Saros 10R, both of which are priced the same at $1,599.99 but have different navigation and mopping systems.

The Saros 10 uses Roborock's semicircular VibraRise mop design like the S series and the company's established navigation technology that uses both LiDAR and an RGB camera, but it puts the LiDAR sensor on a retractable periscope. The Saros 10R, on the other hand, mops with dual spinning pads like the Qrevo Curv and features a new StarSight 2.0 navigation system that ditches LiDAR in favor of dual time-of-flight sensors while retaining the camera. Both the Saros 10 and the 10R support automatic mop detaching, a convenient feature that is not available on previous flagships like the Qrevo Curv or the S8 Max V Ultra ($1,799.99).

The Saros 10 features Roborock's latest VibraRise 4.0 mopping system, an upgrade from version 3.0 on the S8 Max V Ultra that delivers extra downward pressure on the pad and features two sonic zones vibrating separately from each other at a rate of 4,000 times a minute, as opposed to the single zone. Both the Saros 10 and the 10R also feature a small, circular mop pad that juts out to the side to clean corners.

With 22,000Pa, the Saros 10 has slightly more vacuum suction power than the Saros 10R (20,000Pa) and leads the field overall for this spec, besting the Qrevo Curv (18,500Pa) and the Ecovacs Deebot X8 Pro Omni (18,000Pa).

Otherwise, both Saros 10 models come with a dock that can automatically empty the robot's dustbin and wash and dry the mop pad. While washing the mop pad, the dock heats the water to different temperatures to tackle various types of grime: 122 degrees Fahrenheit for starch stains, 140 degrees for grease, and 176 degrees for coffee and sterilization. The base also washes itself with 176-degree water so it doesn't get caked in grime and dries the mops with 140-degree heated air. Both Saros 10 models have a separate detergent dispenser in the dock that adds cleaning solution to the robot's mopping water tank, a feature strangely missing from the Qrevo Curv despite being present on earlier models.

Like the Qrevo Curv, the Saros 10 and 10R have an AdaptiLift chassis that allows them to lift themselves over obstacles and small thresholds. They can clear single-layer thresholds as tall as 1.18 inches and double-layer thresholds as tall as 1.57 inches. The Ecovacs Deebot X8 Pro Omni has a self-lifting chassis as well, but it can only clear thresholds as high as 0.79 inches.

Aside from their cleaning capabilities, the Saros 10 and 10R carry forward the smarts of past models. You can control them with the Roborock app for Android and iOS, third-party smart speakers with Alexa or Google Assistant, and a built-in voice assistant called Rocky. You can use the integrated camera for remote viewing and security patrols, and the robots can be sent to find your pets in a game of hide and seek. You can even talk to your furry roommates once you find them, as the robots support two-way communication.

Design: Short and Spiffy

For this review, Roborock sent me a black Saros 10. You can also get it in white, but the base station's black reflective surface looks simultaneously cool and elegant, which spoke to me and made visiting friends comment on my “fancy” vacuum.

The base measures 18.5 by 16.1 by 17.3 (HWD). The top flips up to reveal clean and dirty water reservoirs. The front has two rectangular, reflective panels. The top panel containing the Roborock logo is mostly just for decoration, but it features a status light in the upper-left corner that shines white when all is well and turns red if it needs your attention. The bottom panel opens when you press it to reveal the dust bag and detergent compartment. Beneath the panels is the bay for the vacuum, with charging contacts on the back and a brush on the bottom that pivots side-to-side to scrape the mopping pad.

The disc-shaped vacuum matches the base in black or white, though the top has a matte finish instead of a reflective one. While the robot is docked, its LiDAR periscope is flush with the top surface in its recessed state, and then it pops up when cleaning.

By the numbers, the robot measures 13.8 by 13.9 inches (LW) and stands 3.1 inches tall with the periscope retracted or 3.7 inches with it extended. Even with its periscope extended, it’s slimmer than the Ecovacs Deebot X8 Pro Omni (13.9 by 13.8 by 3.9 inches) and the Qrevo Curv (13.9 by 13.7 by 4.1 inches).

Like the front of the base, the top of the robot is also separated into two panels, with a status light running across the dividing line between them. It shines white when the robot has greater than 15% battery, glows red when it drops below that, or flashes red to indicate an issue. During remote viewing, the line shines red and white alternately to let anyone in the vicinity know they are being watched.

The rear panel on top of the robot lifts off to reveal the dustbin if you need to manually clean it, as well as a QR code and a reset button for setup. The front panel houses the three buttons comprising the vacuum’s physical controls, each with dual functions depending on whether you press or press and hold. In the center is a power button that turns the robot on and off or starts or pauses a job. It's flanked by Water and Home buttons. The Water button sends the robot on a mop-only run or enables the child lock. The Home button sends the robot back to its dock or, if already docked, prompts it to empty the dustbin or initiate a mop wash.

In front of the buttons is a new upward-facing contact sensor to help the robot determine whether it can fit under a piece of furniture and if it needs to lower its LiDAR periscope to do so. The robot also has wall sensors on the side and cliff and carpet sensors on the bottom. The camera is housed behind a clear panel on the front.

On the bottom of the robot, the brush roll is flanked by the main wheels, and an omnidirectional caster wheel sits front and center with an extendable side brush in the top corner. The side brush has two curved spiral arms, both set to one side to increase centrifugal force as they spin. The semicircular primary mop and the circular edge mop both attach to a removable plate on the bottom of the robot.

Setup and App: Seamless Smarts

In addition to the robot and the base station, the Saros 10 comes with a quick start guide, a user manual, a card with voice commands, and an extra dust bag in addition to the one already installed in the base. When you run out of bags, you can get a pack of six from Roborock for $31.99.

You’ll need to find a home for the base station on a hard floor near an outlet with 2.7 feet of height clearance, 1.4 feet of clearance to the left and right, and 3.3 feet of clearance in front so the robot can come and go with ease. Make sure the spot you pick has good Wi-Fi coverage as well. Then, plug in the base and attach the ramp to the front by snapping it into place.

Fill up the clean water tank and detergent dispenser to finish getting the base ready. Roborock doesn’t include cleaning solution in the box, but you can buy a 16.2-ounce bottle from Amazon for $18.99.

Once the base is ready, hold the power button on the robot to boot it up, then remove the top cover to access the QR code. After you tap the button to add a new device in the Roborock app, it’ll prompt you to scan the code and input your Wi-Fi info. Then, replace the cover and push the home button on the robot so it can dock and charge.

The Roborock app prompts you to tidy up the clutter on your floors and open doors then send the robot on a mapping run. In testing, the Saros 10 took almost 12 minutes to map my two-bedroom, 1,500-square-foot apartment. It took longer to complete this task than the Ecovacs Deebot X8 Pro Omni (almost 8 minutes) and the Qrevo Curv (just over 9 minutes). That said, the Saros 10's auto-generated map looked more detailed than the one I got from the X8. It properly divided most rooms and even correctly labeled some. It took me less than five minutes to make a few tweaks, rename the remaining rooms, and add a couple of keep-out zones. Setting up the map with Ecovacs was more fiddly and took about 15 minutes.

While customizing the map, you can edit the flooring surface of a given room or add furniture, but the Saros 10 did a good job of recognizing both on its own and gradually adding furniture and extra details to the map over time as it worked.

The app's main page shows the saved map, along with the robot's current battery level and details of its last cleaning run (area covered and duration). You can start a cleaning job with the play button at the bottom of this page, and the map stays up to date as the robot works. Above the play button, you can start a cleaning run targeting specific rooms or zones or set up a routine so the robot mops the kitchen every night at a certain time, for instance.

Before sending the robot out to clean, you can choose the mode (vacuum only, mop only, or vacuum and mop) and other cleaning preferences. An AI SmartPlan option lets the robot determine its own cleaning parameters, including vacuum suction power, mop scrub intensity, and water flow levels (with four options for each), or you can customize a plan room by room. You can also set the route to be quick or thorough and the number of cleaning passes (one or two).

The menu button in the upper-right corner lets you manage detailed settings, set schedules, see a run history, and enable experimental features like extra deep cleaning when the robot senses stuck-on dirt. The camera button on the device page starts a remote viewing session, and you can use the on-screen controls to manually steer the robot, tap anywhere on the map to have it navigate right there, send it on an automated patrol, or have it search for your pets.

Navigation: Good at Finding Its Way, But Obstacle Avoidance Could Be Better

I used Roborock’s AI SmartPlan for the majority of my testing, and while determining its own parameters, the Saros 10 completed the first full cleaning run of my apartment in 88 minutes. That time included several mid-run trips back to the base station to clean its mop. It picked up the pace a little on the second run, completing the job in 81 minutes. It was a few minutes slower than the Deebot X8 Pro Omni (77 minutes) but significantly outpaced the Qrevo Curv (102 minutes) with similar settings in the same space.

On whole-home runs, the Saros 10 thoroughly covered every room and navigated nimbly around my furniture. It cleaned in corners and always reliably got back out. The Saros 10 has the rare distinction of never getting stuck a single time during my testing, an achievement that neither the Deebot X8 nor the Qrevo Curv match.

The robot thoroughly cleaned up after my two cats without collecting any tangles on the brush roll or leaving behind any hair clumps or dust bunnies. It never accidentally dropped any collected dirt or litter when going over thresholds, a problem I experienced one time with the Deebot X8.

It didn't fare as well on obstacle avoidance. To test this, I intentionally spread cat toys of various shapes and sizes on the floor, and the Saros 10 hit all of them, including a colorful plastic spring, a foil ball, and both a big and small plastic mouse. Each generation, Roborock touts improved AI-enhanced obstacle detection, but I’ve yet to test a model from the brand that thrives on this test. I find it strange that the Saros 10 can't avoid obstacles, especially given how well its new sensors do at detecting and gently navigating around furniture. For comparison, the Deebot X8 occasionally bumped the bigger toys, but didn’t run over anything and completely avoided the plastic mice.

Battery Life: Enough Power for Most Homes

When tasked with consecutive runs to gauge its real-world battery life, the Saros 10's 6,400mAh cell lasted 118 minutes. In that time, it finished one whole-home cleaning run and roughly half of a second before calling it quits and heading back to its base for a charge.

The Deebot X8 beats it here, lasting 134 minutes, while the Qrevo Curv powered through 120 minutes in this test. Still, its 118-minute battery life goes well beyond the 90-minute threshold we consider sufficient for most homes.

Cleaning Performance: Very Good Vacuuming, Mediocre Mopping

I test vacuuming performance in two different 100-square-foot rooms, one with wall-to-wall carpeting and the other with hardwood. Before each test, I manually vacuum the floor, then spread a specific amount of rice and let the robot run, weighing the dustbin before and after to see how much it picked up. Then I repeat the test on each surface with sand, a more stubborn type of debris. Check out all of the details of my testing procedure here.

The Saros 10 snagged 98.6% of rice on carpet, which is a good result on the easiest test. The Qrevo Curv scored a perfect 100%, while the Ecovacs Deebot X8 came just short of that with 99.9%. Sand on carpet is a suction stress test, and the Saros 10 did the best of the three, picking up 40.7% compared with 37.7% for the X8 and 36% for the Curv.

For these tests, I run the robot in auto mode, if available, to see if it's smart enough to sense the dirt and boost the suction on its own. Surprisingly, the X8’s predecessor, the 8,000Pa Deebot X2 Omni, did better than all three of the 18,000Pa-plus models, scoring 45.6% for the sand-on-carpet stress test.

On hardwood, the Saros 10 slightly outperformed the X8 for both debris types, picking up 95.1% of the rice and 82.8% of the sand, while the X8 snagged 90% and 82.3%, respectively. In this test, the Saros 10 did a good job cleaning along the wall and digging the debris out of the corner of the room. It minimized flinging to an extent, but I did find some grains spread beyond the initial deposit area.

Overall, the Saros 10 did slightly better on our vacuum pickup tests than the X8, though the Deebot also performed well.

The Saros 10 might have partially excelled at these tests because it took its time. It finished its carpet tests in an average of 17 minutes and 44 seconds, taking much longer than the X8 (9:48) and also trailing the Curv (14:46). It went over the middle of the floor more than once during the run, perhaps sensing the extra dirt and giving that area more attention. On hardwood, it averaged 17:19 and occasionally stopped back at the base to wash its mop pads mid-job. Hybrid units typically take longer to clean hardwood than carpet, with the X8 averaging 13:18 for the former in my tests.

In terms of mopping performance, the Saros 10's VibraRise 4.0 system didn't fare particularly well on my scrubbing stress test. For this test, I closed the robot into a room with 0.25 ounces of raspberry jelly spread on a single spot on hard flooring. The Saros 10 left a smear of the initial stain, spread seeds and stickiness to other parts of the floor, and its self-washing feature couldn’t get the mop clear of jelly either.

The Deebot X8 did much better with its relatively unique roller mop design, picking up most of the original stain and leaving no sticky residue and only a couple of stray seeds, though its self-washing feature didn't fully flush the spindle after the run. Most robot mops with spinning circular mop pads have also done better on this test than the Saros 10, including the Qrevo Curv, which left a small pink splotch in the original area but didn’t spread any seeds.

Verdict: A Better Vacuum Than Mop

The Roborock Saros 10 combines best-in-class suction power with the mop and detergent dispenser from the S8 MaxV Ultra and the self-lifting chassis from the Qrevo Curv. It goes toe-to-toe with the Ecovacs Deebot X8 Pro Omni when it comes to vacuuming, but its mopping performance falls short of other high-end hybrids. If you're set on a Roborock model, we prefer the Qrevo Curv for its superior mopping performance. That said, the Ecovacs Deebot X8 Pro Omni offers even more effective scrubbing and better obstacle avoidance at a lower price, earning it our Editors’ Choice for high-end hybrid floor cleaners.
