22" Battery-Powered Floor Scrubber Machine | RT50+ Lithium Warehouse Floor Cleaner

The RT50+ is built for daily cleaning on commercial hard floors. It is suitable for concrete, epoxy, tile, marble, terrazzo, PVC, emery, and mirror tile floors.

Use it when you need a cleaner, more consistent finish on sealed hard surfaces. It is not designed as a carpet extractor, so for carpeted areas we recommend using dedicated carpet-cleaning equipment instead of a rotary hard-floor scrubber.

The RT50+ runs up to 5 hours and fully charges in about 3.5 hours. That makes it a practical choice for facilities that clean during the workday and cannot leave a scrubber charging overnight.

The lithium battery is designed for faster charging and longer service life than the standard RT50 battery setup. If charging downtime is a key concern, the RT50+ is the better fit in the RT50 family.

The RT50+ is a walk-behind, hand-push floor scrubber. It is not self-propelled.

This is a good match when you want a simpler, lower-maintenance warehouse floor cleaner with a compact footprint. If your team needs powered drive assistance for longer routes or heavier daily use, compare it with the RT50D Self-Propelled Scrubber.

The RT50+ comes ready for practical startup with the key cleaning parts included. The package includes batteries, a built-in charger, adjustable squeegee assembly, squeegee rubber, duty brush, and burnishing pad.

That means you do not need to order basic startup parts separately before first use. Review the included manual, install the required parts, add clean water and approved detergent, and your team can begin testing the machine on a small floor area.

No, when used correctly, the RT50+ is designed to scrub and recover dirty water in one pass. The 31-inch suction working width pulls wastewater into the 14.5-gallon recovery tank after the front brush cleans the floor.

A small amount of water in the tank or hose when the machine arrives is normal. Every unit is tested with clean water before shipping, and any green liquid you notice is antifreeze solution used to protect internal components during cold transit or storage. Rinse or run the machine briefly before regular cleaning.

The RT50+ is rated at 68 dBA, so it is suitable for many commercial spaces where cleaning needs to happen without excessive disruption.

For warehouses, gyms, banquet halls, and retail back rooms, the battery-powered design also removes cord trip hazards and keeps the cleaning route easier to manage. For noise-sensitive spaces, test during off-peak hours first and adjust your cleaning schedule if needed.

Light setup is required, but the RT50+ is designed for straightforward first use. The machine ships with the main cleaning components included, and the product page provides operation and control-panel manuals for startup guidance.

Before cleaning, check the squeegee, brush or pad, battery charge, solution tank, and recovery tank. Start with a small test area so your operator can confirm water flow, brush contact, and suction pickup before cleaning the full facility.

Yes. SUNMAX carries RT50 series accessories and replacement parts, including items such as brush plate and pad driver screws, caster wheels, solution tank measure cups, and charging-port parts.

For ongoing maintenance, keep common wear parts such as pads, brushes, and squeegee rubber on your checklist. You can browse SUNMAX Accessories or contact our team before ordering if you want to confirm compatibility with your RT50+.

The RT50+ includes a 2-year manufacturer warranty for qualifying defects in materials and workmanship under normal use and maintenance.

Warranty coverage applies to the original purchaser and excludes consumable wear parts such as brushes, pads, and squeegees. For a claim, keep your proof of purchase and contact SUNMAX with issue details, photos, or videos. You can review our Warranty Policy for full coverage terms.

The RT50+ ships with free freight shipping to the lower 48 states. The product page lists delivery in 3–8 business days.

Because this is a heavy commercial machine with a packaged weight of 305 lb, please make sure your delivery location can receive freight. If you need help confirming delivery details before purchase, contact SUNMAX Support with your shipping address and facility requirements.

The biggest difference is charging speed. The RT50+ uses a lithium battery setup that charges in about 3.5 hours, while the standard RT50 lists an 8-hour charging time.

Both models list up to 5 hours of working time, so choose RT50+ if your facility values faster turnaround, less downtime, and a lighter lithium-battery cleaning workflow.
