Roborock’s New Robovac Can Climb Stairs
Roborock has announced its first-half 2026 product line-up at CES in Las Vegas, introducing a range of new robotic cleaning devices, including a stair-climbing prototype robovac known as Saros Rover.
SAROS ROVER: STAIR-CLIMBING ROBOTIC VACUUM PROTOTYPE
Roborock’s most notable reveal was the Saros Rover, described by the company as the first robotic vacuum to use a two wheel-leg architecture designed to climb stairs while actively cleaning them. Each wheel-leg can raise and lower independently, allowing the robot to adjust its height, maintain a level body, and move across uneven terrain.
According to Roborock, the system combines AI-based motion control with 3D spatial sensing to adapt to changing surfaces in real time. The company says this enables the Saros Rover to navigate straight, curved, and carpeted staircases, including those with bullnose edges, as well as slopes and complex multi-level thresholds.
Roborock positions the Saros Rover as a potential solution for multi-storey homes, where conventional robot vacuums are typically restricted to a single floor. The Saros Rover is currently a product in development, with no confirmed release date.
SAROS 20 AND SAROS 20 SONIC
Roborock also announced two new flagship models for 2026, the Saros 20 and Saros 20 Sonic, which build on the Saros series introduced in 2025.
The Saros 20 features an updated StarSight Autonomous System 2.0, which Roborock says can now recognise up to 201 objects. It also introduces AdaptiLift Chassis 3.0, allowing the robot to climb single thresholds up to 4.5 cm or double-layer thresholds measuring 4.5 cm plus 4 cm.
The Saros 20 Sonic focuses on a lower-profile design, using RetractSense Navigation to achieve a body height of 7.98 cm. It also debuts the VibraRise 5.0 mopping system, which uses an extendable sonic mop scrubbing at up to 4,000 vibrations per minute to reach edges more effectively.
Both models are powered by a 35,000 Pa HyperForce motor and use a redesigned RockDock that supports hot-water mop washing at up to 100°C.
QREVO CURV 2 FLOW
The Qrevo range is also expanding with the introduction of the Qrevo Curv 2 Flow. This model is Roborock’s first robot vacuum to use a roller-based mopping system rather than traditional pads.
The Qrevo Curv 2 Flow includes SpiraFlow real-time self-cleaning, applies up to 15 N of downward pressure during mopping, and uses an edge-adaptive roller that extends to improve edge coverage while protecting carpets.
Although it has yet to be confirmed, it’s expected that all three models, along with their variants, will be Matter compatible either out of the box once launched, or get Matter compatibility via an update.
