Roborock unveils the world’s first two-wheel-legged robo vacuum, new Saros 20 series, and more at CES 2026
At CES 2026, Roborock unveiled the world’s first two-wheel-legged robo vacuum, the new Saros 20 series, and more.
The Saros Rover, features the world’s first two-wheel-leg architecture in a robovac. Each wheel-leg provides reach, lift, height, and imitates human mobility, enabling the robot to raise and lower each one of the wheel-legs independently, execute small jumps, agile turns, sudden stops, and directional changes, all while maintaining a level body as the ground changes.
At a software level, Saros Rover harnesses the power of Artificial Intelligence algorythms, in conjunction with complex motion sensors and 3D spatial information to understand its environment and make its wheel-legs react with precision.
The Saros 20 and Saros 20 Sonic robot vacuums, introduce new mobility, navigation and cleaning systems designed to reduce manual intervention in everyday use. To address a common failure point for robot vacuums in homes, the Saros 20 series features the new AdaptiLift™ Chassis 3.0.
The system adjusts chassis height and wheel positioning to maintain traction across two closely spaced floor transitions, such as kitchen sliding door frames, which many robots struggle to clear. The Saros 20 series supports these back-to-back height changes up to a combined 8.5 cm, roughly the height of a credit card standing on its edge.
Saros Rover
The Saros Rover excels in multi-storey homes, where it is able to clean each one of the steps of a staircase as it goes to the second floor, dramatically reducing “no-go” zones and transitioning into cleaning areas previously inaccessible for homes with a single robovac.
The Saros Rover is able to tackle several types of non-flat surfaces, with staircases being the most obvious one. This includes not only traditional staircases but also curved staircases, or even carpeted staircases with bullnose fronts, all while cleaning each one of their steps as it navigates through them.
Other types of surfaces that Saros Rover is able to tackle include slopes as well as complex multi-level room thresholds requiring height and power. Saros Rover is a real product in development with an unconfirmed launch date.
Saros 20
Designed for the needs of open, high-traffic homes, the Saros 20 uses the StarSight™ Autonomous System 2.0, a vision-based navigation platform that recognises over 200 object types and scans its environment up to 21 times more frequently than conventional LDS LiDAR systems, enabling real-time map updates and more stable navigation in busy, ever-changing spaces.
It pairs this with a dual-spinning mop system that can adaptively increase downward pressure to tackle tougher stains commonly found in high-traffic areas.
Saros 20 Sonic
The Saros 20 Sonic is designed for homes with tighter layouts, denser furniture placement and frequent transitions between carpets and hard flooring.
It uses the RetractSense™ Navigation System, which features a retractable LDS LiDAR sensor and a 100-degree rear-facing field of view, enabling it to operate under low furniture and in very tight clearances. Reactive AI 3.0 Obstacle Recognition adds multi-sensor perception to improve environmental awareness and positioning accuracy.
The Saros 20 Sonic also features VibraRise® 5.0, a high-frequency vibrating sonic mop designed to maintain flat, consistent contact along edges and in confined spaces. With the ability to control downward pressure, the Saros 20 Sonic can clean effectively even with limited space.
