RT50D Self-Propelled Floor Scrubber – 22 in. Cleaning Path, 36,000 sq. ft./hr

The SUNMAX RT50D is a strong fit for commercial and industrial facilities that need a self-propelled walk-behind floor scrubber for daily hard-floor cleaning. With a 22-inch cleaning path, 31-inch squeegee width, and up to 36,000 sq. ft./hr cleaning efficiency, it is well suited for warehouses, schools, hospitals, shopping centers, retail stores, workshops, and other medium-size cleaning routes.

The RT50D is a self-propelled walk-behind floor scrubber with a dedicated traction motor that powers forward travel while the operator steers the machine. A pad-assist model relies on brush rotation to help it move and generally requires more operator input to maintain forward motion.

The RT50D is therefore better suited to longer cleaning routes, frequent daily use and operators who would benefit from reduced pushing effort. Actual handling will vary with floor condition, travel speed and machine setup.

The RT50D is designed for common sealed hard floors, including concrete, epoxy, commercial tile, terrazzo, vinyl, PVC and marble. For polished stone, specialty coatings or sealed wood, use a compatible non-aggressive brush or pad, apply a neutral-pH low-foam cleaning solution and test a small, inconspicuous area first. Always follow the flooring manufacturer’s care instructions. The RT50D is not designed for carpet or unsealed, damaged or water-sensitive flooring.

The RT50D is rated up to 36,000 sq. ft. per hour under ideal operating conditions. Actual productivity depends on floor layout, soil level, operator speed, obstacles, water changes, and cleaning route. For many facilities, it is a practical choice for daily cleaning in medium-size warehouses, schools, gyms, retail spaces, and commercial buildings.

The RT50D provides up to 5 hours of continuous working time. Battery runtime can vary based on floor condition, brush pressure, water use, operator habits, and cleaning intensity. The lead-acid battery system typically requires about 8 hours to fully charge.

Yes. The RT50D is a floor scrubber dryer machine. The brush scrubs the floor while the vacuum and 31-inch squeegee recover dirty water, helping leave the floor cleaner and drier in one pass.

The RT50D ships by LTL freight, and free freight shipping is included within the lower 48 U.S. states. Most orders are processed within 1-3 business days, with an estimated delivery window of 3-8 business days after shipment. Freight delivery is curbside by default, so the carrier is not required to move the machine indoors. Please use a valid street address and phone number, and make sure someone is available to receive and inspect the shipment.

The RT50D is backed by SUNMAX 2-year manufacturer warranty coverage for qualifying defects in materials or workmanship under normal use. Wear parts such as brushes, pads, and squeegee blades are not covered the same way as non-wearable parts.

SUNMAX also offers support for compatible RT50 series replacement parts, including brush/pad components, caster wheels, charging parts, and other service items. If you are not sure which part fits your machine, contact SUNMAX support with your model, order number, and photos.

Choose the RT50D for a cost-effective 22-inch self-propelled floor scrubber with lead-acid power, especially for medium cleaning routes and tighter aisles. Choose the RT50D+ when you want the same 22-inch cleaning path with faster lithium recharging.

Choose the RT50DW for a wider 28-inch dual-brush path that reduces the number of passes across larger open areas. Choose the RT120 for a 34-inch cleaning path, larger tanks and lead-acid power, or the RT120+ for the same large-area format with faster lithium recharging. Compare your narrowest aisle, floor layout, daily workload and available charging time before ordering.
