The Ecovacs Deebot X2 Omni and the Roborock S8 Pro Ultra are two of the most expensive robot vacuums available. Aside from the ability to vacuum and mop, both can automatically empty their dustbin and clean their mopping pads. They also offer impressive navigation skills — allowing them to deftly move around your home without getting caught on toys, clothes, or other hazards.

If you’re shopping at the top end of the market, there’s no doubt you’ve encountered these two products. But which is the best robot vacuum: the Deebot X2 Omni or Roborock S8 Pro Ultra? Here’s everything you need to know before making a purchase.

Pricing and availability

The Ecovacs Deebot X2 Omni costs $1,500 and is available in black and white. It’s often on sale, with prices dipping as low as $1,200 during big shopping holidays. The Roborock S8 Pro Ultra is slightly more expensive at $1,600 and is also available in black and white. It doesn’t go on sale quite as frequently as the X2 Omni — though Roborock products generally do see small discounts around the holidays.

Vacuuming

Both the X2 Omni and S8 Pro Ultra are excellent at vacuuming carpets and hard floors. The Ecovacs X2 Omni can muster up a staggering 8,000 Pa of suction, which makes it one of the most powerful robot vacuums around. Toss in an edge-sweeping brush, square design for better access to corners, and a rubber roller brush, and there are few robot vacuums that perform as well as the X2 Omni.

The Roborock S8 Pro Ultra maxes out at 6,000 Pa, but despite the lower power, it still manages to vacuum slightly better than the X2 Omni. Part of this is due to the DuoRoller Riser Brush, which uses two rubber brushes to untangle hair and other debris from your carpet more effectively than the single roller on the X2 Omni.

Like the X2 Omni, it also uses an edge-sweeping brush, though it lacks a square design and instead is the standard circular shape. However, the two rubber brushes are great at avoiding tangles while still keeping your carpet clean, giving the Roborock device a slight advantage.

Mopping

Once again, both the X2 Omni and S8 Pro Ultra are at the top of the class. The X2 Omni employs two rotating mopping plates to tackle stains and spills. It also applies downward pressure while mopping, ensuring tough spots are cleaned properly. The X2 Omni lifts its mopping plates 15mm when traveling on carpet — but because the mopping fabric dangles down several millimeters, plush carpets still get slightly damp.

The X2 Omni features a built-in water reservoir, allowing it to staycontinuously wet its mops. This is ideal for large homes, as it ensures the mopping pads don’t dry out during long cleaning runs. Ecovacs says the reservoir is large enough to clean a house up to 4,400 square feet in a single run.

The S8 Pro Ultra uses a single mopping pad that rapidly vibrates to scrub floors. Like the X2 Omni, it applies downward pressure while mopping. It only lifts its mopping pad 5mm when traveling on carpet, which results in slightly damp carpets. Thankfully, its mopping pad isn’t nearly as thick as those on the X2 Omni, meaning the amount of “carpet wetting” is about even between the two products.

Unfortunately, the built-in water reservoir on the S8 Pro Ultra isn’t quite as robust as that of the X2 Omni, as it’s only capable of cleaning up to 3,230 square feet.

Additional features

As you’d expect from products that cost over $1,000, the X2 Omni and S8 Pro Ultra come with heaps of additional features. You’ll find the following on both robot vacuums:

  • Self-emptying dustbins
  • A dock that cleans the mopping pads with hot water
  • A dock that dries mops after each cleaning run
  • Smartphone apps to modify settings
  • The ability to create restricted zones
  • The ability to automatically detect different surfaces
  • The ability to automatically adjust cleaning power for extra-dirty areas

The X2 Omni and S8 Pro Ultra are both easy on the eyes, and the availability of both black and white models makes it easy to find something that’ll fit in with your home.

One of the most unique features available on the S8 Pro Ultra is the ability to charge the device during off-peak hours. This helps lower the ongoing operating costs of using a robot vacuum. Its smartphone app is also a bit more streamlined than the Ecovacs smartphone app, making it easier to find the features you’re looking for without too much digging. And while both are excellent navigators, the S8 Pro Ultra seemed to have less trouble finding its way around my home. I also had to rescue it fewer times than the X2 Omni, though both are leagues ahead of the competition.

Unique features available on the X2 Omni include support for two-way video calls and the built-in YIKO voice assistant. YIKO isn’t quite as robust as you’d expect for such a premium device, and there’s a good chance you’ll completely ignore it, opting instead to set up an automated cleaning schedule. And while the two-way video call option is nice, the low angle makes it less effective than a dedicated indoor camera.

Which is the better robot vacuum and mop combo?

At the end of the day, it’s impossible to go wrong with either the Ecovacs Deebot X2 Omni or the Roborock S8 Pro Ultra. These two premium robot vacuum and mop combos offer everything you’d want from this type of device, giving you an automated cleaning routine that can go weeks without any manual intervention. Most homes will be well-served regardless of which one is picked — so consider snagging whichever one is cheapest.

Alternatively, consider picking up the S8 Pro Ultra if your home is mostly carpet and the X2 Omni if your home is mostly hard floors. While performance is similar across both devices, the dual-roller brush system on the S8 Pro Ultra is impressive and great at avoiding tangles. Meanwhile, the dual rotating mopping pads on the X2 Omni are well-suited for tackling vast rooms with hard floors.

Still uncertain which is best for your home? Then simply pick the one you think looks more stylish. These two luxurious robots are evenly matched at just about every turn — so whichever one will look best in your home is the one you should pick up.

The Saros Z70 is the most exciting robot vacuum I’ve ever seen

Out of all the robot vacuum brands available in 2025, Roborock is probably my favorite. The company has been churning out premium, reliable, and powerful robots for years, with their releases consistently landing on our best robot vacuum and mop roundup. CES 2025 was filled with intriguing smart home reveals, but the Roborock Saros Z70 is by far the coolest upcoming device. Designed with a robotic arm that can pick up small obstacles that get in its way, it’s the most innovative robot vacuum I’ve ever seen -- and I’ve never been more excited to see how it shakes up the industry.

Robot vacuums are intended to be autonomous assistants that roam our homes and keep floors clean with little manual intervention. But far too often, this isn’t the case. Whether it be poor sensors that cause the robot to get stuck, suction power that’s inadequate to pick up troublesome debris, or poor obstacle navigation that causes it to get tangled in your phone’s charging cable, some robots simply aren’t as hands-free as expected.

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.
