General Parameter
Up to 4.5 + 4.3 cm double-layer threshold
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-first dynamic cleaning for up to 3 cm 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 3 cm.
* This function needs to be manualy enabled in the Roborock app.
Prevent 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.
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*

DirTect Technology: Stain-Target AI Cleaning*

*This function needs to be manually enabled in the Roborock app. Based on internal testing carried out by the manufacturer. Actual results may vary depending on environmental factors.
