Sunmax RT50+ 22" Battery-Powered Floor Scrubber The SUNMAX RT50+ is a 22" lithium battery-powered walk-behind floor scrubber built for heavy-duty cleaning in industrial and commercial settings such as warehouses. It is compatible with mirror tile, marble, epoxy, PVC, emery, terrazzo, and concrete floors, scrubbing and recovering dirty water in a single pass. The unit features a 14.5-gallon recovery tank, a 550W brush motor at 200 RPM, and a cleaning efficiency of up to 30,000 square feet per hour. Its lithium battery supports a fast 3.5-hour charge, 1,000+ charge cycles for a 5 to 6 year service life, cold-weather operation, and carries a four-year warranty. The rotationally molded polyethylene housing resists corrosion and impact, and an ergonomic wide handle supports cordless, low-strain operation. 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, and the machine is ready for use after a quick rinse or initial run.
