Roborock at CES 2026: Stair-climbing robot vacuums, sonic mopping and a big bet on smarter homes

At CES 2026, Roborock showed off its most ambitious ideas yet. From a stair-climbing robot vacuum to refined flagships and even robotic lawnmowers.

Roborock arrived at CES this year with one of the event's showstoppers. The headline act was undoubtedly the Saros Rover, a prototype robovac that uses a wheel-leg system to climb stairs, slopes and awkward thresholds. It’s an audacious idea, and one that tackles a problem robot vacuums have ignored for years.

If Roborock can turn Saros Rover into a reliable consumer product, it could remove one of the last major limitations of robot vacuums. Multi-storey homes have always required compromises, additional devices, or manual intervention. A robot that can clean stairs as it climbs them feels disruptive, even if it’s still some way from a confirmed launch. There are still open questions. Staircases are unpredictable, cluttered spaces, and long-term reliability will matter far more than demo-friendly tricks. But as a concept, Saros Rover feels like the first rethink of robot vacuum mobility, rather than another incremental boost to suction or AI labels. Alongside the experimental hardware, Roborock also revealed more immediate updates to its core range.
