Roborock Saros Rover: The World’s First Stair-Climbing Robot Vacuum with Wheel-Leg Architecture
For years, the "final frontier" for robot vacuums hasn’t been thick carpets or pet hair—it has been the staircase. At CES 2026, Roborock officially conquered that obstacle with the debut of the Saros Rover, a revolutionary cleaning robot featuring the industry's first wheel-leg architecture. Unlike any robot vacuum before it, the Saros Rover doesn’t just avoid stairs; it climbs them, cleaning every step along the way.
A Paradigm Shift in Robotic Design
The Saros Rover moves away from the traditional puck-shaped chassis in favor of two independent, highly articulated wheel-legs. This design mimics human mobility, allowing the robot to:
- Lift and Reach: Each leg operates independently to step up or down.
- Stay Level: While the legs adjust to the terrain, the main body remains level to ensure consistent suction and stability.
- Dynamic Movement: The robot can jump over small obstacles, turn on a dime, and adjust its height to navigate steep slopes or high thresholds.
Powered by advanced AI algorithms and motion sensors, the Saros Rover uses 3D spatial mapping to react to terrain changes in real-time, ensuring it never loses its footing on uneven surfaces.
High-Power Cleaning Meets High-Mobility
While the Saros Rover is built for agility, it doesn’t skimp on performance. It is equipped with a HyperForce motor delivering 19,000 Pa of suction. While some of Roborock’s single-floor flagships offer higher raw numbers, the Saros Rover is optimized to maintain that power even while ascending a staircase.
Navigation is handled by the new StarSight 2.0 system, which utilizes Dual-Flash LiDAR. This allows the robot to:
- Map Multi-Story Homes: Create seamless maps that connect different floors via the stairs.
- Dodge Moving Obstacles: Effortlessly navigate around pets or moving objects (like a rolling ball) while on a slope.
- Cleaning Modes: The robot can fully vacuum each step during its ascent or descent, or disable the vacuum motor for "fast transit" between floors.
Conquering the "No-Go" Zones
The Saros Rover was designed specifically for complex multi-story environments. In live demos at CES, the robot proved its versatility by handling:
- Diverse Stair Types: It easily navigated traditional wooden stairs, curved architectural stairs, and carpeted steps with bullnose edges.
- Obstacle Clearance: It tackled multi-level thresholds and steep slopes that would ground a standard robot.
- Agility: In a show-stopping display of its motor control, the Saros Rover even performed small jumps and "danced" for the audience, proving its sensors can handle rapid, non-linear movements.
The Future of Whole-Home Automation
The Saros Rover is the culmination of years of legged-robot prototypes from Roborock. While the current version is a vacuum-only model, Roborock has hinted that mop integration is in the pipeline for future iterations.
By eliminating the need for users to carry their robots between floors, Roborock is effectively ending the era of "no-go zones." While the Saros Rover is currently in the development phase—with pricing and a formal release date yet to be announced—it has firmly established itself as the frontrunner in the next generation of home robotics.
