Overview

The Roborock Saros 20 is Roborock’s flagship robot vacuum and mop, with 36,000Pa HyperForce suction and the StarSight Autonomous System 2.0, which uses 3D ToF sensing and an RGB camera. The robot is 7.98 cm tall with low-clearance navigation down to 7.95 cm, and it recognises more than 300 obstacle types, down to objects 2 cm wide and 2 cm tall.

It mops with two 200 RPM spinning pads that press down at 8N, or 13N with Deep Cleaning for Heavy Dirt or Stains switched on, and a FlexiArm mop that reaches out to edges and corners. The dock empties the robot for up to 65 days, washes the mops with water up to 100°C, dries them with 55°C warm air, refills the robot with warm water and adds detergent automatically. The AdaptiLift Chassis 3.0 climbs double-layer thresholds up to 8.8 cm (4.5 cm plus 4.3 cm), and the robot works with Alexa, Siri, Google Home and Matter.
