Roborock is one of our favorite robot vacuum brands, as the team is responsible for some of the best robot vacuum and mop combos on the market. The Roborock S8 MaxV Ultra is a prime example of this, as it offers heaps of suction, robust mopping skills, and an automated docking station that handles much of the regular maintenance. The new Roborock Qrevo Curv, revealed at IFA 2024, is following in those footsteps — but it makes a few big changes to the formula.

So, which robot vacuum and mop combo is better for your home? The old Roborock S8 MaxV Ultra, or the fancy new Roborock Qrevo Curv? Here’s a look at both to help you decide.

Pricing and design

Pricing for the Qrevo Curv in the U.S. is yet to be announced, though it’ll cost 1,300 euros in Europe. That roughly converts to $1,450. The Roborock S8 MaxV Ultra costs $1,800. No matter how you cut it, both of these robots are extremely expensive — though the S8 MaxV Ultra will likely be the pricier option in North America.

The Qrevo Curv looks unique among all robot vacuums, thanks to a domed docking station that houses its clean water, dirty water, and dustbag. The S8 MaxV Ultra is a bit more conventional with an angular design. They both look great, though the innovative curved appearance of the Qrevo Curv will probably appeal to more shoppers.

Winner: Roborock Qrevo Curv

Vacuuming

With a staggering 18,500Pa of suction, the Qrevo Curv is much more powerful than the S8 MaxV Ultra, which only offers 10,000Pa of suction. This allows it to work well on all surfaces, including thick carpets. The Curv also employs a DuoDivide Brush design that better handles hair, pet fur, and other objects that could cause tangles. Both feature a FlexiArm side brush to help reach near baseboards and around furniture.

Once vacuuming is done, they’ll head back to their docks to automatically empty their dustbins. Both can go up to seven weeks before needing to replace their dustbag. Of course, this will vary based on the size of your home, how dirty it is, and how often you run the robot — but both are very hands-off when it comes to vacuuming maintenance.

Winner: Roborock Qrevo Curv

Mopping

This is where the two robots start to diverge. The Roborock S8 MaxV Ultra uses a large mopping plate that rapidly vibrates to clean floors, along with a small mopping pad on its side to clean closer to baseboards. Our testing showed it to work well, and it can even be paired with a detergent that’s automatically dispensed at the base station for an enhanced clean.

As for the Qrevo Curv, it uses two spinning mopping pads — one of which can swing outward to reach closer to baseboards and around furniture. These work just as well as the vibrating plate of the S8 MaxV Ultra, and the swinging design allows the robot to clean tight areas that might otherwise be missed. The robot doesn’t, however, automatically dispense detergent like the S8 MaxV Ultra.

Both robots can also lift their brushes as needed to improve the overall mopping experience and keep their brushes dry.

Both docking stations wash and dry their mops. They can also detect if dirt is still present and will continue washing until the mops are completely clean.

Winner: Tie

Additional features

You’ll find heaps of additional features on the S8 MaxV Ultra and Qrevo Curv, including the built-in Rocky voice assistant, support for the versatile Roborock app (where you can set schedules, update cleaning settings, and place restricted zones), retractable mops that help keep carpets dry, and impressive obstacle detection to prevent it from bumping into toys, shoes, cables, and other hazards.

The Roborock S8 MaxV Ultra can lift its mop by 20 millimeters, while the Qrevo Curv can lift its entire chassis 10mm and its mops by 10mm. It can even cross thresholds 4cm tall — so if your rooms are separated by thick dividers, you won’t need to manually pick up the robot to continue your cleaning. Testing found this to be a mixed bag, however, as sometimes it would try to climb over obstacles that it really should have avoided (such as the stand for a stationary bike).

Which is the better robot vacuum and mop combo?

The Qrevo Curv is the better robot vacuum and mop combo for most shoppers. Not only is it cheaper than the Roborock S8 MaxV Ultra, but it offers more suction and an improved DuoDivide Roller design — not to mention a cool chassis-lifting feature. Its docking station is also more inspired, and it’ll likely fit in better with modern décor.

If you already own the S8 MaxV Ultra, the only reason you should consider upgrading is if you want the additional suction offered by the Curv. The extra 8,500Pa is nothing to scoff at, and our testing found it to do an excellent job tackling thick carpets. But if your home is largely comprised of hard floors, consider sticking with the S8 MaxV Ultra and making good use of its auto-dispensing detergent.

The best robot vacuums of CES 2025: Roborock, Dreame, Ecovacs, and more

CES is the place to go if you want to see the newest and hottest tech, and each year there seems to be one type of product that really steals the show. At CES 2025, that was robot vacuum cleaners. These little gadgets have been around for years now, but companies like Roborock, Dreame, and Narwhal are leading the charge with innovation and new technologies that make them even more efficient at what they do.

We spent a lot of time speaking with the teams behind these machines and watching them in action for ourselves, and these five robot vacuum cleaners are our top picks of CES 2025. As for hands-on impressions, you'll just have to wait until we have the chance to review some of these cutting-edge cleaners later this year.

Ecovacs shows off powerful Deebot X8 Pro Omni robot vacuum at CES 2025

Ecovacs came out swinging at CES 2025, revealing a slew of smart home products running the gamut from robot vacuums and lawnmowers to bizarre window-cleaning robots. The star, however, was the Deebot X8 Pro Omni -- a powerful robot vacuum that makes big changes to its mopping abilities thanks to a new collaboration with Tineco.

Though it didn’t pick up a robotic arm like the Roborock Saros Z70, the Deebot X8 Pro Omni did learn some cool new mopping techniques. There are two big upgrades here, the first being additional pressure while mopping. The X8 Pro Omni can create up to 4,000Pa pressure and spin at up to 200 rpm, which should result in better cleaning than anything else we’ve seen from Ecovacs so far. The other upgrade is a self-washing mop, which continually cleans itself while mopping your floors, ensuring every mess is tackled by a clean mop.

Narwal debuts innovative robot vacuum with new mop-cleaning functionality at CES 2025
Narwal Flow

Narwal is responsible for some of our favorite robot vacuums, including the premium Narwal Freo Z Ultra, which features a modern aesthetic and ultra-quiet operation. The company’s track record of innovation continued at CES 2025 with the reveal of the Narwal Flow -- an upcoming robot vacuum built with a powerful new mopping system.

The Narwal Flow employs a new type of mopping system (dubbed the FlowWash Mopping System) that actively cleans its rolling mopping plate as it's cleaning your floors. This ensures you won’t be tracking dirty mops across the ground and should result in a better overall cleaning experience. The robot is equipped with both a clean and dirty water tank, allowing it to extract dirty water from the mop while simultaneously rewetting it. This allows the mop to remain in excellent condition without needing to head back to the docking station for self-cleaning.
