The Xiaomi Robot Vacuum S40 Pro is designed for advanced and precise whole-home cleaning. Its dual extended arms ensure edge-to-edge coverage, allowing the side-brush to reach 0 mm from walls and the mop pad to come as close as 1 mm — making sure no dirt or dust is left in corners.
Powered by a 15,000 Pa high-suction fan with aluminum-magnesium alloy blades, it effectively removes dust, debris, and pet hair from hard floors and carpets. The dual mop pads rotate at 180 rpm and offer three adjustable water-flow levels, simulating manual wiping for superior stain removal.
For navigation, it uses a 360° LDS laser scanning system with a 129° ultra-wide structured-light sensor, allowing precise mapping and obstacle avoidance even in low-light conditions. The smart carpet-recognition system automatically lifts the mop pads by up to 10 mm when moving onto carpets, ensuring efficient cleaning without wetting surfaces.
With a powerful 5,200 mAh battery, 430 mL dustbin, and 310 mL water tank, the S40 Pro can clean up to approximately 180 m² in a single session. It supports multiple cleaning modes such as vacuum-only, mop-only, or combined operation. Users can manage cleaning schedules, set no-go zones, and control the robot through the Xiaomi Home App with compatibility for voice assistants like Google Assistant and Amazon Alexa.
