The Roborock Saros 20 Sonic Complete is a comprehensive cleaning robot designed to handle both vacuuming and mopping across large homes. It features a powerful suction of 36000 Pa and a vibrating microfiber cloth for scrubbing floors, while the DuoDivide anti-tangle system prevents hair from clogging the brush. To navigate your space, the device combines LiDAR LDS, structured light, and an AI RGB camera, allowing the Reactive AI 3.0 system to recognize and avoid over 300 different objects in real-time. It can even identify particularly dirty areas to provide extra cleaning where it is needed most. One of its most notable capabilities is the ability to cross thresholds up to 8.8 cm, making it easier to move between rooms with significant lips or dividers. When it encounters carpets, the robot automatically detects them and lifts the mop up to 3 cm to keep fabrics dry. The integrated camera also doubles as a tool for remote home surveillance via the app, and you can control the unit using Google Assistant, Alexa, or Siri. With a battery life of up to 3 hours and 10 minutes, it can cover areas up to 340 square meters on a single charge. The accompanying station automates the most tedious parts of maintenance by emptying the 0.2 l onboard dustbin into a 2.7 l bag and managing water through 4 l clean and 3.5 l waste tanks. It keeps the mopping system hygienic by washing the cloth with hot water reaching 100°C. Measuring 35.3 x 35 x 7.98 cm and weighing 5.10 kg, the robot maintains a slim profile to reach under furniture, while the station provides a centralized hub for all its self-cleaning functions.
