SUNMAX RT50+ 22" Lithium Walk-Behind Floor Scrubber

Overview

The SUNMAX RT50+ is a lithium-powered 22-inch walk-behind floor scrubber for warehouses and commercial facilities that need cordless cleaning and faster recharge turnaround. It retains the RT50 family’s large tanks and wide squeegee while shortening the published charging time.

Why choose this model?

• Lithium recharge is about 3.5 hours compared with about eight hours for the standard RT50.
• The 22-inch brush cleans hard floors while the 31-inch squeegee collects wastewater.
• Separate 13.2-gallon solution and 14.5-gallon recovery tanks support extended routes.
• Walk-behind operation suits teams that prefer direct control of machine movement.

Controls and practical features

A rotationally molded polyethylene housing resists corrosion and impact, while the wide handle supports operator control. This is a hand-push model; choose a self-propelled model if powered travel is important.

Included equipment

• Lithium battery
• Built-in charger
• Squeegee assembly and squeegee rubber
• Scrubbing brush
• Pad holder and burnishing pad

Specifications

Productivity and runtime are manufacturer ratings, not guaranteed results for every facility. Turns, obstacles, soil level, tank stops and cleaning settings affect actual output.

Buying Guide

Will it fit my cleaning route?

This model suits regular commercial hard-floor routes. Check doorway and aisle clearance, storage space and the location of fresh-water and wastewater facilities. For longer routes, drive assistance or a ride-on machine may be worth comparing.

Which power configuration am I buying?

This listing is the lithium configuration. Plan charging around the published recharge time and use the supplied or manufacturer-approved charger. Actual runtime depends on floor condition, cleaning settings and battery use.

Which floors can it clean?

For approved hard floors such as sealed concrete, tile, epoxy and vinyl. Check the floor manufacturer’s maintenance instructions and choose a compatible brush or pad and detergent. Water-sensitive wood, laminate, coatings and polished finishes need particular care. This machine is not a carpet extractor.

Ask CleanGearHQ for help choosing a model. Share your floor type, usable cleaning area, narrowest aisle or doorway and charging or outlet access so we can help check the fit.

Compare before choosing

Compare the SUNMAX RT50 for standard lead-acid power and the SUNMAX RT50D+ for self-propelled lithium operation.

Operation and routine care

• Use a floor-compatible, low-foaming cleaning solution and follow its dilution instructions.
• Drain and rinse the recovery tank after use, and inspect the brush, squeegee and suction path for debris.
• Check brushes, pads and squeegee blades regularly; these are maintenance items that wear with use.
• Follow the battery and charger instructions before first use, between shifts and during storage.

Before first use

SUNMAX says small amounts of test water or green transit-protection fluid may remain after factory testing. Follow the operating instructions for the initial rinse and setup.

Replacement parts

For replacement-part help, provide CleanGearHQ with your model, order number and photos of the part. Confirm brush, pad and squeegee compatibility before ordering; availability varies.

Warranty support

SUNMAX publishes a two-year limited manufacturer warranty for eligible defects in non-wearable parts under normal use and maintenance. Brushes, pads and squeegees are consumables rather than covered wear items. Keep proof of purchase; manufacturer eligibility, exclusions and claim assessment apply.
