Overview

The Saros 20 is built for homes where thresholds, rugs and furniture usually interrupt a robot. Its AdaptiLift Chassis 3.0 combines vision, adaptive algorithms and lifting wheels so the robot can cross double-layer thresholds up to 3.46 in and keep cleaning from room to room. Roborock rates the motor at 36,000 Pa, and the chassis can raise or lower itself to keep suction effective on carpet up to 1.18 in deep.

For hard floors, dual rotating mops press down with up to 13 N, and FlexiArm extends both the side brush and the mop into corners and along baseboards. When the robot reaches carpet, the mops detach and the chassis lifts so rugs stay dry. Back at the RockDock, mops are washed with water heated up to 212°F and dried with warm air, the dust bin empties into a bag, and clean water and detergent are refilled automatically.
