Built for Daily Commercial Hard Floor Cleaning: Designed for warehouses, factories, schools, hospitals, retail stores, gyms, offices, and facility maintenance teams that need to clean large hard-floor areas more efficiently than mop-and-bucket cleaning. Ideal for routine cleaning on sealed commercial floors.
22″ Scrubbing Path with One-Pass Water Recovery: The 22″ brush path scrubs the floor while the 31″ squeegee helps recover dirty water in the same pass. The 550W brush motor delivers 200 RPM scrubbing action, while the 550W suction motor supports efficient water pickup after cleaning.
Cordless Walk-Behind Design for Easier Daily Use: Battery-powered operation removes the need to drag a power cord across the floor. The machine supports up to 4 hours of operation with about 8 hours recharge time, making it practical for routine aisles, corridors, open areas, and daily cleaning routes.
Check Floor Type, Space, and Tank Size Before Ordering: Best for sealed hard floors such as tile, concrete, epoxy, vinyl/VCT, terrazzo, sealed stone, polished floors, and hard non-porous gym rubber floors. Features a 13.2-gal clean-water tank, 14.5-gal recovery tank, 22″ brush path, and 31″ squeegee width—please confirm doorway width, aisle space, storage area, floor surface, and rubber flooring type before purchase.
Complete Kit, Easy Setup & U.S. Support: Includes batteries and charger, brush, red/white/black pads, pad holder, squeegee assembly, and 2 sets of rubber blades for quick tool-free setup. Backed by a 2-year limited warranty, 24/7 U.S. support, and onsite repair support when applicable; use low-foam detergent and clean tanks/squeegee after use.
