As expected, Roborock has landed at CES 2026 with fleet of new robotic vacuum cleaners. But the model that’s real dominating headlines right now has to be the Saros Rover – the “world’s first robotic vacuum with AI-powered wheel-leg architecture that can both navigate stairs and slopes with human-like agility while cleaning them.”
The world-first Roborock Saros Rover brandishes the world’s first two-wheel-leg architecture in a robotic vacuum. There are a pair of articulating legs, both with wheels as feet, that allow the bot to reach, lift, adjust its own height, and, according to Roborock, imitate human mobility. Each of the legs can raise and lower the robot independently, “execute small jumps, agile turns, sudden stops, and directional changes, all while maintaining a level body as the ground changes.”
This is, of course, all made possible by way of AI algorithms alongside a series of “complex motion sensors and 3D spatial information to understand its environment and make its wheel-legs react with precision.”
Last year, we saw robot vacuums with arms that can pick things up of the floor as well Anker models that can slide inside of a secondary unit to get a lift up the stairs. But with the Saros Rover it’s all about the legs, and this time it’s got a pair of its own – this not only allows the unit the climb the stairs and slopes, but also clean them on the way up “dramatically reducing no-go zones and transitioning into cleaning areas previously inaccessible for homes with a single robovac.”
It seems to be a much more elegant and efficient way of tackling multi-story homes than the impressive clunky implementation we saw last year where you effectively needed a second robot just to climb the stairs without cleaning them.
Roborock says the unit can handle several types of non-flat surfaces, including “not only traditional staircases but also curved staircases, or even carpeted staircases with bullnose fronts, all while cleaning each one of their steps as it navigates through them. Other types of surfaces that Saros Rover is able to tackle include slopes as well as complex multi-level room thresholds requiring height and power.”
Roborock has specifically stated that Saros Rover is a “real product in development,” but it has yet to deliver a launch date or a price. The Saros Z70 from last year launched at $2,600 (currently $2,000), and that only has one arm and doesn’t clean the stairs.
