SUNMAX 22″ Auto Floor Scrubber Dryer Walk‑Behind with LiFePO4 Battery

Description

Product Overview

The SUNMAX RT50D-Plus29 is a premium walk‑behind auto floor scrubber dryer designed for demanding commercial environments. Built around a robust 0.7 horsepower motor and a high‑capacity 29.2V LiFePO4 lithium‑ion battery, this machine delivers up to five hours of uninterrupted cleaning on a single charge. A wide 22‑inch cleaning path allows operators to cover up to 36,000 square feet per charge cycle, making it ideal for large‑scale facilities such as warehouses, schools, gyms, and retail stores. The unit features a rugged steel frame, corrosion‑resistant components, and intuitive controls that let users adjust speed and direction with a simple knob and drive/reverse buttons. Dual‑tank architecture keeps clean and dirty water separate, while a 31‑inch quick‑dry squeegee and high‑efficiency suction system leave floors dry and safe immediately after use.

Usage

This floor scrubber dryer excels on a variety of hard‑floor surfaces, including concrete, tile, epoxy, vinyl, and wood. Its 200 RPM brush rotates at a speed optimized for both light dust removal and heavy grime scrubbing, ensuring a consistent finish across different substrates. The machine’s self‑propelled design reduces operator effort, allowing a single staff member to maneuver the unit through tight aisles, around obstacles, and across uneven terrain with ease. Because the battery is lithium‑based, the unit starts instantly without the warm‑up time associated with lead‑acid batteries, and it can be recharged in just 3.5 hours. The compact footprint (45 × 23 × 37 in) and 294‑pound weight make it portable enough for multi‑site use while still providing the durability required for industrial‑grade cleaning tasks.
