RT120 34" Self-Propelled Floor Scrubber for Large Commercial Spaces

Yes. The RT120 Self-Propelled Floor Scrubber Machine is built for large commercial and industrial hard-floor spaces where a smaller walk-behind scrubber would require too many passes, refills, and operator effort.

With a 34" brush scrubbing width, 38.8" squeegee suction width, and estimated efficiency of up to 75,000 sq.ft/h, it is a strong fit for warehouses, factories, hospitals, shopping malls, airports, schools, and workshops. For smaller areas or tighter budgets, compare it with our self-propelled floor scrubber collection.

The RT120 is designed for commercial hard floors, not carpet extraction. It works especially well on concrete, ceramic tile, porcelain tile, quarry tile, VCT, LVT, laminate, terrazzo, epoxy-coated floors, sealed hardwood, granite, marble, and limestone.

For sensitive floors such as sealed hardwood, marble, or softer stone, use the correct pad or soft brush and test a small area first. The machine delivers 110 lbs of brush pressure, so pad choice matters when protecting finished surfaces.

The RT120 is rated for up to 75,000 sq.ft/h under ideal cleaning conditions. That makes it one of the higher-capacity SUNMAX walk-behind style options for teams cleaning wide aisles, production floors, retail backrooms, gym corridors, and other open hard-floor areas.

Actual productivity depends on floor layout, soil level, turns, refill time, and operator pace. The 31.7-gal solution tank and 33-gal recovery tank help reduce stop-and-go downtime on larger jobs.

The RT120 provides up to 4 hours of estimated run time on a full charge. It uses a 24V/120Ah lead-acid battery, with an estimated charge time of 8 hours.

This makes the machine a practical choice for scheduled daily cleaning routes. For operations that prefer lithium power, compare the RT120+ Lithium Battery Floor Scrubber, which shares the same large-format RT120 cleaning platform with a lithium battery configuration.

The RT120 is the better choice when cleaning width, tank size, and hourly coverage matter more than compact storage. Compared with smaller models such as the RT50D Self-Propelled Floor Scrubber, the RT120 steps up to a 34" brush path, 33-gal recovery tank, and up to 75,000 sq.ft/h cleaning efficiency.

Choose RT50D for tighter facilities, ramps, and medium commercial routes. Choose RT120 when your team needs to cover much larger hard-floor areas with fewer tank stops.

Yes. The RT120 is designed to remove common commercial and industrial floor soils, including dust, dirt, debris, oil, grease, spills, mud, scuff marks, shoe marks, and sticky residue.

Its dual brush motors, 200 RPM brush rotation speed, 110 lbs brush pressure, and 1.34 HP suction motor help scrub and recover dirty water in one pass. For adhesive residue or chewing gum, use the right chemical or removal process before relying on normal daily scrubbing.

The RT120 is rated at 69 dBA, which is manageable for many commercial indoor cleaning schedules. It is suitable for professional maintenance teams working in warehouses, schools, hospitals, retail spaces, and other active facilities.

For noise-sensitive areas, schedule cleaning during lower-traffic hours and confirm your facility’s internal sound requirements before purchasing.

The RT120 is a commercial floor cleaning machine, but it does not require building-level installation. Before first use, inspect the shipment, check the tanks and brush/squeegee area, charge the battery, and follow the startup steps in the machine documentation.

A small amount of clean water or green anti-freeze solution may be present because every machine is tested before shipping. A quick rinse or initial operation prepares the machine for regular use.

The RT120 ships by freight, with free freight shipping to the 48 contiguous states. Floor cleaning machines are typically delivered in 3–8 business days after processing, depending on location and carrier availability.

Standard freight delivery is curbside delivery, so the driver is not required to move the machine indoors. Please have someone available to receive and inspect the shipment. Any damage or missing items should be noted on the delivery receipt and reported within 24 hours. See our Shipping Policy for full freight guidelines.

The RT120 is backed by SUNMAX support, replacement parts availability, and a 2-year manufacturer warranty from the date of delivery for defects in materials and workmanship under normal use and maintenance.

Wear items such as brushes, pads, and squeegees are treated as consumable parts. RT120 replacement items, including squeegee rubber, scrub brushes, vacuum motor, and burnishing pads, are available in the product accessories section. For return eligibility, SUNMAX offers a 30-day return window under the conditions listed in our Refund Policy and Warranty Policy.
