Roborock Demos Stair-Climbing Saros Rover at CES 2026

The legged vacuum is a working prototype with no release date as Roborock treads carefully after last year’s poorly reviewed arm-equipped model.

Overview

  • Live demos showed the Rover raising and lowering each leg independently to vacuum individual stair treads, performing small hops, and balancing as it ascended.
  • Roborock says the prototype uses AI with motion sensors and 3D spatial data to keep its wheel-legs stable and responsive on stairs and uneven surfaces.
  • A Verge reporter observed it climb five steps in just under three minutes with a few teetering moments, highlighting impressive control but slow, cautious movement.
  • Alongside the prototype, Roborock refreshed its lineup with the Saros 20 and Saros 20 Sonic, both rated at 35,000 Pa suction and featuring new mopping and threshold-climbing systems.
  • Roborock confirmed the Qrevo Curv 2 Flow will be available Jan. 19 at a $849 promotional price before rising to $999, as CES coverage points to a broader shift toward specialized home robots.
