It is compatible with concrete, ceramic/porcelain/quarry tile, VCT and LVT vinyl, hardwood (with soft brushes or appropriate pads), laminate, terrazzo, epoxy-coated floors, and natural stone including granite, marble, and limestone. Cleaning performance includes a 200 RPM brush speed, 110 lb brush pressure, and a 3.4 mph maximum forward speed, with a 31.7-gallon solution tank and 33-gallon sewage tank for extended sessions between refills and dumps. The high-capacity battery supports up to 4 hours of continuous run time. Each unit is factory-tested with clean water before shipping, so a small amount of residual water may remain in the tank or hose. Any green liquid present is anti-freeze solution added to protect internal components during transit and cold-condition storage.
