Roborock Unveils Stair-Climbing Saros Rover at CES

At the Consumer Electronics Show in Las Vegas, Roborock unveiled the Saros Rover, a prototype robot vacuum designed to climb stairs independently while continuing to clean, marking a potential advancement in household robotics. The device, showcased on Tuesday, features a unique two-wheel-leg architecture that allows it to navigate multi-level homes without human intervention.

The Saros Rover has a rectangular body supported by two jointed legs, each ending in a wheel. These legs extend and bend independently, enabling the vacuum to lift its body nearly a foot off the ground, pivot sharply, execute small jumps and handle slopes or thresholds. Unlike accessory-based solutions from competitors such as Eufy's MarsWalker or Dreame's CyberX, which require robots to enter a separate carrier for stair transport, the Saros Rover integrates the capability directly and vacuums surfaces during ascent or descent. Demonstrations at the event showed it ascending straight and curved stairs, maintaining balance on ramps and avoiding obstacles using artificial intelligence algorithms, motion sensors and three-dimensional spatial mapping.
