cm
Double-Layer Threshold⁴
An advanced vision system, adaptive algorithms, and a main wheel + auxiliary wheel + climbing arm lifting structure allow the robot to analyze, test, and memorize the best way to cross thresholds—ensuring uninterrupted cleaning across every room. 

Industry-First⁵ Dynamic Cleaning for Up to 3cm Carpets

Experience industry-first dynamic chassis elevation. Intelligently adjust the body height to maintain optimal suction and ensure deep cleaning performance across carpets with pile height up to 3cm⁶..
With AdaptiLift Chassis 3.0 and StarSight™ Autonomous System 2.0, Saros 20 is engineered for high-threshold crossing, precise mapping and seamless cleaning.

Preventing Getting Stuck

The robot automatically elevates its chassis or independently adjusts its front, rear, left, or right sides to free itself if it gets trapped..

No Space too Tight,

No Place Unreachable

Low-Clearance Navigation Down to 7.95

Slides Smoothly into Lower Spaces

Equipped with the next-gen StarSight™ Autonomous System 2.0, the Saros 20 achieves a remarkably slim profile, effortlessly navigating under sofas and beds as low as 7.95 cm with advanced localization and mapping capabilities*.
*The body height of the robot vacuum is 7.98 cm. Due to slight vertical flexibility in the front structural components, the robot may achieve limited passive compression when entering low-clearance spaces, allowing access down to 7.95 cm. However, please note that scraping may occur. Actual performance may vary depending on environmental conditions.

  • Extends to Clean 

    Toe-Kick Areas*

    Identifies toe kick areas as low as 2 cm⁷ and extends FlexiArm™ Arc Side Brush to sweep hidden dust away.

  • AreasClean Beyond 

    Curtains*

    Crosses marked curtains with ease—reaching hidden spaces behind for a complete clean.*
*This function needs to be manually enabled in the Roborock app.

*Users should manually mark the location of the curtains on the map through the Roborock app to trigger this function. Actual results may vary depending on environmental factors.
