Roborock turned heads at CES 2026 with a fresh take on a problem robot vacuums have struggled with for years: stairs. Enter the Roborock Saros Rover, a new robot vacuum concept that can literally stand up on two extendable legs, helping it climb steps, stay stable, and clean areas most robovacs still can’t reach.
CES 2026 was already a big stage for Roborock, with multiple product reveals shown in Las Vegas. The company highlighted flagship models such as the Saros 20 and Saros 20R, alongside the Qrevo Curv 2 Flow, which is notable for being Roborock’s first robot vacuum equipped with a roller mop. Roborock also showcased the F25 Ace Pro wet/dry vacuum featuring foam cleaning, plus the RockMow X1 LiDAR, a new lawnmower model that drops real-time kinematic (RTK) positioning. Even with that lineup, the Saros Rover managed to become one of the most talked-about demos thanks to its unusual mobility design.
Unlike stair-climbing robot vacuums that rely on continuous tracks, the Saros Rover uses two leg-like extensions mounted on its sides. In Roborock’s official demonstration, these legs lift the robot while keeping balance and stability at the center of the design. The idea is that the vacuum can remain upright and controlled even when bumped, reducing the risk of tipping over during movement.
This dual wheel-leg setup isn’t just for climbing. It also allows the Saros Rover to rotate more flexibly and even perform small hops, giving it a wider range of motion than typical robot vacuums. The most practical benefit, however, is how it handles stair cleaning: the robot can move sideways along steps by alternating between its two independently controlled legs. That sideways motion is designed to help it actively clean each stair step rather than simply trying to get from one floor to another.
For smart home fans looking for a robot vacuum that can handle multi-level homes, the Saros Rover points to an exciting future where stair cleaning could become a real, everyday feature instead of a novelty. Roborock hasn’t shared pricing or release timing yet, but the CES 2026 debut makes it clear the company is exploring new ways to expand what a robot vacuum can do—especially in homes where stairs have always been the ultimate no-go zone.
