Roborock has unveiled what it calls the world’s first two-wheel-legged robot vacuum at CES 2026, alongside two new models in its Saros 20 series, as the company pushes further into advanced home robotics.
The new Saros Rover prototype introduces a two-wheel-leg architecture designed to replicate aspects of human mobility. Each wheel-leg can be raised or lowered independently, allowing the robot to adapt to uneven terrain while maintaining a level body, according to the company.
At a software level, Roborock said Saros Rover uses artificial intelligence algorithms, motion sensors and 3D spatial data to interpret its surroundings and react with precision. The system enables agile turns, sudden stops and directional changes, as well as small jumps to overcome obstacles.
Stair-Climbing Robot Vacuum Targets Multi-Storey Homes
Roborock positioned the Saros Rover for multi-storey homes, where traditional robot vacuums are limited by stairs. The company said the robot is able to clean each step of a staircase as it ascends, reducing so-called “no-go” zones and allowing access to areas previously unreachable for single-unit robot vacuums.
The Saros Rover is designed to handle a range of non-flat surfaces, including curved staircases and carpeted stairs with bullnose edges. It can also traverse slopes and complex multi-level thresholds that require additional height and traction.
Roborock said Saros Rover is a real product currently in development, but did not confirm pricing or a commercial launch date.
Saros 20 Series Focuses on Navigation and Reduced Manual Intervention
Alongside the Rover concept, Roborock introduced the Saros 20 and Saros 20 Sonic robot vacuums, which are aimed at improving navigation and cleaning performance in everyday homes.
Both models feature the new AdaptiLift™ Chassis 3.0, designed to address a common failure point for robot vacuums: closely spaced floor transitions. The system dynamically adjusts chassis height and wheel positioning to maintain traction across back-to-back obstacles, supporting combined height changes of up to 8.5cm, the company said.
Vision-Based Navigation and Sonic Mopping
The Saros 20 is designed for open, high-traffic homes. It uses Roborock’s StarSight™ Autonomous System 2.0, a vision-based navigation platform that recognises more than 200 object types and scans its environment significantly more frequently than conventional LDS LiDAR systems, enabling real-time map updates.
It also features a dual-spinning mop system that can increase downward pressure to tackle tougher stains in busy areas such as kitchens and living spaces.
The Saros 20 Sonic, by contrast, targets tighter layouts with dense furniture and frequent transitions between carpets and hard floors. It uses the RetractSense™ Navigation System, which includes a retractable LDS LiDAR sensor and a wide rear-facing field of view, allowing the robot to clean under low furniture. Reactive AI 3.0 Obstacle Recognition adds multi-sensor perception to improve positioning accuracy.
