Two-legged Roborock Saros can climb and clean your stairs

After a brief tease earlier in the week, Roborock has announced the Saros Rover, a robot vacuum capable of climbing and cleaning stairs.

Stairs have so far been the ultimate foe for many robotic appliances. Between the risk of falling down stairs or being unable to move between floors automatically, it’s one thing home robot manufacturers haven’t been able to crack yet.

Roborock reckons it has the answer with the Saros Rover, an appliance that has extendable legs with wheels at the end. In a public demo at CES 2026, the robot can be seen slowly climbing a set of stairs, extending and retracting its legs to hoist itself up each step.

But it doesn’t just climb stairs; it can stop mid-climb, pivot, and clean along the way. By hooking one leg up, the Saros Rover can turn and move back and forth to vacuum a step before fully ascending to the next one.

It’s hoped that the Saros Rover will be able to clean multi-storey homes without any user intervention required. It’s not unheard of for some households to have multiple robot cleaners — one for each floor — which a device like this could resolve.

Unlike a lot of devices shown at CES that never leave the concept phase, the Saros Rover is in active development and will launch in the future, Roborock confirmed.

In a more conventional approach, Roborock also announced the Saros 20 and Saros 20 Sonic robot cleaners. A sequel to last year’s Saros 10 flagship range, the Saros 20 boosts the motor power up to 35,000Pa. It also gets an upgraded navigation system that can map faster, plus an improved lifting mechanism capable of scaling home thresholds up to 4.5cm high.

Roborock’s wet-dry vacuum range gets an upgrade, too, with the F25 Ace Pro equipped with a foaming solution designed to break down annoying floor stains. It also has a 25,000Pa suction power, a 35 per cent larger water tank than previous F25 models, and a hot water self-cleaning station.

Australian prices and release dates for Roborock’s new Saros 20 and F25 appliances are expected later in the year.
