Yes, the robot vacuum's base station washes and dries the roller mop by itself, preventing the wet rag smell. It features an OmniCyclone station that handles solution dispensing, mop washing, and drying automatically, keeping the mop fresh and clean without manual intervention. The system uses hot water and hot air drying during the self-cleaning process to maintain freshness and avoid unpleasant odors. This advanced self-cleaning and drying function is part of the base station's design to ensure the roller mop stays clean and odor-free after use.
