Sunmax RT50D+ Self-Propelled Battery Powered Floor Scrubber, 22" Brush Cleaning Path The SUNMAX RT50D+ is a 22" self-propelled lithium battery floor scrubber with a 31" squeegee width, built for medium-to-large commercial hard floors. It is intended for warehouses, schools, retail stores, gyms, workshops, and showrooms, and is compatible with mirror tile, marble, epoxy, PVC, emery, terrazzo, and concrete floors. It is not designed for carpet, and works with most cleaning agents on the market. The unit features forward and reverse self-propelled drive, a 13.2-gallon solution tank, and a 14.5-gallon recovery tank, with a working efficiency of up to 36,000 square feet per hour. It runs on a lithium battery rated for up to 5 hours of operation with a 3.5-hour recharge, and its squeegee assembly scrubs, recovers water, and leaves floors dry in a single pass. 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.
