Roborock Saros 20X

We thought Roborock had already said everything there was to say about "flat" navigation with the Saros 10R. We were wrong. At CES 2026, the company raised the bar even further by presenting the new Saros 20X, and today we can tell you about it!

It's not an aesthetic revolution—the design remains the sleek, clean one we've come to appreciate—but under the hood lies a technical refinement that aims to address the remaining physical limitations that still hold robots back in many modern homes. If the 10R won us over with its ability to fit anywhere, the 20X promises to add to this agility a climbing power we've never seen before on a home appliance.

He's getting up!

The Saros 20X's strong point remains its ultra-low profile: at just 79.5 mm tall, it can navigate areas where competitors with traditional laser turrets get stuck. In place of the rotating mechanical LiDAR, it features the StarSight Autonomous System 2.0, a navigation platform that boasts a sampling rate 21 times higher (according to Roborock) than traditional LDS systems. This allows for extremely rapid mapping of environments and a vision that recognizes over 300 different types of obstacles.

But the truly intriguing new hardware feature is the new AdaptiLift Chassis 3.0. Roborock has introduced a dedicated climbing arm and a dynamic lifting system for the main and auxiliary wheels that allows the robot to climb over double-layered thresholds up to a total of 8.8 cm (specifically, a combination of 4.5 + 4.3 cm). This specification doubles the performance seen on the previous generation and opens up new possibilities for those with significant differences in height between rooms, particularly thick carpets, or who don't want to reposition the robot by hand.

Flat design

Aesthetically, the robot maintains the cleanliness of the Saros models, eliminating the upper turret for a more modern and functional look, just like the 10R. The real star of the setup, however, is the new RockDock. The charging station now integrates a mop washing system with water heated up to 100°C. This practically boiling water ensures true sterilization of the cloths, dissolving grease and killing bacteria much more effectively than previous models. And in fact, even leaving it sitting for a few days, the water in the waste tank is less foul-smelling than usual.

In addition to mopping, the dock also handles mop drying with hot air at 55°C and automatic dust emptying, with a bag that lasts up to 65 days before requiring intervention. The vacuuming system continues to use the DuoDivide dual brushes, which channel dirt while minimizing hair tangles.

Clean my house

Moving on to the road test, the first thing that struck us was the speed of the initial mapping: the StarSight 2.0 proves to be quick at understanding the layout of the home. Once cleaning begins, the robot moves very confidently, with a mastery of the space that inspires peace of mind; it avoids obstacles with pinpoint precision and never seems "lost," even in complex environments.

However, not everything is perfect. We noticed that the RockDock's drying cycle is particularly loud, probably the loudest of any robot vacuum we've tested so far. It's not a disturbing noise during normal daily activities, but if you have the dock in a quiet room, you'll definitely hear it. On the software front, the "Hello Rocky" voice assistant continues to provide us with linguistic gems: despite updates, it still clearly mispronounces the word "dust," which once again made us smile but highlights the localization capability that still needs improvement. Furthermore, despite recognizing 300 obstacles, thin, flat electrical cables remain a stubborn enemy that's always best removed before use.

Conclusion

The Roborock Saros 20X is undoubtedly a high-end machine that consolidates the brand's leadership in the ultra-flat navigation sector. Its ability to climb obstacles up to 8.8 cm is a game-changer for those with homes on multiple levels or with significant thresholds.

If you're looking for the latest technology or need to manage uneven surfaces that stymie any other robot, the 20X is the right choice. However, if you already have a Saros 10R at home, the new features, while interesting, don't seem radical enough to justify the expense of an immediate upgrade. It's a solid evolution, but not a revolution compared to the previous generation.
