The Xiaomi S40C Robot Vacuum Cleaner delivers robust cleaning performance with an impressive suction power of up to 5,000 Pa.

Featuring a hybrid vacuum and mopping system, this robot cleaner is built with an electronically controlled 260 mL water tank offering three output levels. The precise water distribution system prevents over-saturation and leaks, ensuring hard floors receive an even and safe clean every time.
