The Roborock Saros 20 Sonic Complete is a comprehensive cleaning system designed to handle both vacuuming and mopping across large homes of up to 340 square meters. It features a powerful 36,000 Pa suction capacity and the VibraRise 5.0 system, which uses sonic vibrations at 4,000 cycles per minute and 14N of downward pressure to scrub floors. To ensure a thorough clean in every corner, the robot utilizes an extendable mop head and a FlexiArm Arc side brush. Hair management is simplified by the DuoDivide main brush, which can handle strands up to 40 cm long without tangling. Navigation is handled by the RetractSense system, combining a retractable LDS sensor, an AI RGB camera, and VertiBeam lateral structured light. This allows the device to maintain a slim profile of 79.8 mm in height, helping it fit under lower furniture. The Reactive AI 3.0 technology recognizes over 300 types of objects in real time, while the AdaptiLift Chassis 3.0 and omni-directional wheels enable the robot to cross double-layer thresholds up to 8.8 cm and lift its mopping system 3 cm when it detects carpets. The accompanying RockDock station automates maintenance by managing a 4-liter clean water tank and a 3.5-liter dirty water tank, washing the mops with hot water reaching 100°C. It also includes a 2.7-liter dust bag to minimize manual emptying. With a battery life of up to 3 hours and 10 minutes, the robot can cover extensive areas on a single charge. You can manage the device via voice assistants like Alexa or Siri, or use the camera for remote home monitoring and capturing 'Pet Snaps' of your animals.
