The Xiaomi Robot Vacuum S40 is a smart robotic vacuum and mop designed for automated wet and dry floor cleaning across various home surfaces. It uses LDS laser navigation to scan and map indoor spaces, enabling structured cleaning routes that help ensure consistent coverage across rooms. The round, low-profile design supports smooth movement under furniture and along edges.

Equipped with a high-performance motor, the S40 delivers strong suction for removing dust, debris, and pet hair from carpets and hard floors. The integrated mopping function allows simultaneous vacuuming and light floor wiping. A large-capacity battery supports extended cleaning sessions, while automatic recharging enables the robot to return to its dock and resume cleaning when power is restored. Control and customization are available through the Xiaomi Home App, with additional support for voice control through compatible smart assistants.
