Sunmax RT35 17" Walk Behind Floor Scrubber Machine, 19000 sqft/h, with Anti-Collision Wheel The SUNMAX RT35 is a 17" walk-behind floor scrubber with a 22" suction width, designed for efficient cleaning in commercial and industrial spaces. It is intended for schools, retail stores, warehouses, and hospitals, and removes grime, stains, and buildup from hard surfaces such as tile, concrete, vinyl, and epoxy. The unit features a durable squeegee assembly and high brush pressure, with a user-friendly control panel and a compact design for maneuvering tight corners and narrow aisles. It is available in two battery options: the RT35 lead-acid model requires approximately 8 hours for a full charge, while the RT35+ lithium model requires approximately 4 hours. A complete set of accessories is included for immediate use. 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.
