Saros 20 is engineered to master every home environment. The new AdaptiLift™ Chassis 3.0 conquers 1.77 + 1.57 inches thresholds. With StarSight™ Autonomous System 2.0, it maps faster, positions more precisely, recognizes obstacles with greater accuracy, and also slides into lower spaces with 3.14 inches body height. With its triple liftable structure, dual anti-tangle system, and the brand new RockDock®, smarter, hands-free cleaning becomes effortless.
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.
