Roborock has introduced the Saros Rover at CES 2026, unveiling what it calls the world’s first wheeled-leg robot vacuum. The concept device features two articulated limbs with integrated wheels, allowing it to climb stairs and clean each step independently, something traditional robot vacuums have never achieved.
The Saros Rover uses a dual-leg system where each leg moves separately. It lifts and lowers its chassis to scale staircases, adjust to uneven floors, and cross multi-level thresholds. Roborock demonstrated the device on the CES show floor, where it climbed five steps in under 40 seconds while cleaning each one. The robot balanced itself using one leg for support as it rolled across each tread.
The Rover’s core hardware includes the AdaptiLift Chassis 3.0, which enables it to adjust height on the fly and clear obstacles up to 3.3 inches tall. It can handle steep ramps, curved stairs, and high-pile carpets. Roborock paired this mechanical system with AI-powered navigation, using 3D spatial sensors and real-time object recognition to avoid collisions and adapt to fast-changing environments.
Roborock confirmed that the Saros Rover remains in development and does not have a release date. The company said it is still deciding whether to integrate a mopping system. The current version focuses on vacuuming, with future updates expected to expand its cleaning capabilities.
The Saros Rover follows the company’s earlier efforts, like the Saros Z70, which featured a robotic arm. Roborock appears to be moving cautiously with this new model after receiving mixed feedback on previous experimental designs, as per The Verge.
The company has not announced a price, but it is expected to cost more than the Z70, which launched at $2,599. The Saros Rover marks a major step in robotic home cleaning, especially for users in multi-floor homes who have waited years for a robot vacuum that can finally tackle stairs.
