RT120+ 34" Self-Propelled Commercial Floor Scrubber – Lithium Battery, 33-Gal Recovery Tank

The RT120+ is made for commercial and industrial hard floors. SUNMAX recommends it for concrete, ceramic tile, porcelain tile, quarry tile, VCT, LVT, terrazzo, epoxy-coated floors, laminate, natural stone, and hardwood when the correct soft brush or pad is used.

This makes the RT120+ Self-Propelled Floor Scrubber a strong fit for large facilities that need daily soil, dust, spill, scuff, mud, oil, and grease removal on hard surfaces.

The RT120+ is rated up to 75,000 sq.ft/h. It has a 34-inch cleaning width, dual 17-inch brush trays, a 38.8-inch squeegee, and up to 3.4 mph forward speed.

For buyers comparing walk-behind machines, this model is best suited for bigger open areas where a smaller floor scrubber would require too many passes, refills, and battery stops.

The RT120+ runs for about 3.5–4 hours per charge. The product specifications list a lithium battery charging time of 3–4 hours, and the product description notes fast charging at about 3.5 hours.

The lithium system also supports partial charging, which helps teams add useful runtime during breaks instead of waiting for a full charge cycle every time.

The RT120+ is designed for straightforward setup, not complex installation. Before first use, inspect the shipment, remove packaging, check the brush and squeegee area, rinse or run the machine briefly if any test water or anti-freeze residue is present, then charge the battery and follow the operator instructions.

Because this is a freight-shipped industrial floor scrubber, please also confirm that your team can safely move the machine from curbside delivery into your facility.

The RT120+ product page specifies a lithium battery system and dual brush design. The listed specifications include a 12V/120Ah lithium battery, dual 17-inch brush disks, and a lithium charging time of 3–4 hours.

For the exact accessory pack in the current shipment batch, SUNMAX recommends confirming with a product specialist before ordering, especially if your site needs a specific pad, soft brush, or replacement squeegee blade.

No, the RT120+ is not a carpet extractor. It is a commercial floor scrubber dryer for hard surfaces such as concrete, tile, VCT, LVT, terrazzo, epoxy-coated floors, laminate, natural stone, and appropriate sealed hardwood applications.

If your facility has both carpet and hard floors, use the RT120+ for the hard-floor zones and select a dedicated carpet cleaning machine for carpeted areas.

The RT120+ is built to scrub and recover water in the same pass. It uses a 38.8-inch suction scraper, 33-gallon recovery tank, and 1000W vacuum motor to pick up dirty solution after scrubbing.

A small amount of water in the tank or hose at delivery is normal because SUNMAX fully tests each machine with clean water before shipping. Green liquid may be anti-freeze solution used to protect internal components during transit and storage in cold conditions.

Before first startup, inspect, rinse, charge, and test the machine in an open area. Check the packaging and delivery receipt, confirm the squeegee and brush area are secure, rinse out any remaining clean test water or anti-freeze solution, then charge the lithium battery before regular operation.

Because the machine is water-tested before shipment, seeing a small amount of liquid does not mean the unit is used. It is part of SUNMAX quality control.

Inspect the shipment upon delivery. If there is damage or a missing item, note it on the delivery receipt, take photos, and contact SUNMAX within 24 hours.

Yes, SUNMAX lists RT120 accessories and replacement parts. Available product-page accessories include RT120 rubber squeegee blades, soft black disk scrub brushes, a vacuum motor, and burnishing pads for RT120/SM860 machines.

This matters for commercial buyers because brushes, pads, and squeegee blades are wear items and should be planned into routine maintenance.

Yes, SUNMAX provides U.S.-based support and up to a 2-year warranty. The SUNMAX warranty is valid for 2 years from the date of delivery and covers defects in materials and workmanship for the original purchaser under normal use and maintenance.

Consumables and wear parts such as brushes, pads, and squeegees are not covered as warranty items. For warranty claims, keep your proof of purchase and be ready to provide photos or videos. See the SUNMAX Warranty Policy.
