RT35 17" Walk Behind Floor Scrubber Machine, 19000 sqft/h, with Anti-Collision Wheel

The SUNMAX RT35 walk behind floor scrubber has a rated productivity of 19,000 square feet per hour, which is significantly faster than traditional mop-and-bucket cleaning in commercial settings. With a 17-inch brush and 22-inch squeegee, plus continuous run time of up to 2–2.5 hours per charge, a single RT35 can realistically cover medium to large facilities such as gyms, retail stores, and warehouses during daily maintenance routes. For even higher throughput or multi-building campuses, multiple walk behind floor scrubber machines can be deployed to increase total hourly coverage and reduce labor cost per square foot.[web:9]

Both versions are walk behind floor scrubber machines with identical 17-inch cleaning width and 19,000 sqft/h productivity, but they use different battery technologies. The RT35 lead-acid model uses a 24V/45Ah battery pack with an approximate charging time of 8 hours, while the RT35+ lithium model uses a 24V/52Ah pack with about 4 hours charging time and similar 2–2.5 hour continuous run time, giving faster turnaround and greater convenience for operations that need multiple cleaning cycles per day. Lithium battery systems generally offer longer cycle life and lower daily maintenance (no watering) compared with lead-acid batteries, which makes the RT35+ a strong choice for busy facilities that rely heavily on walk behind floor scrubber machines.[web:9]

The SUNMAX RT35 walk behind floor scrubber is designed for hard surfaces such as tile, concrete, vinyl, epoxy, terrazzo, and similar sealed commercial floors, using its rotating brush and squeegee system to remove dirt and recover solution effectively.Customer reviews and SUNMAX product descriptions also highlight successful use in environments like garages, event halls, and large homes with hard floors, where the RT35 can maneuver into bathrooms and tight spaces while still delivering professional-grade cleaning results. For delicate surfaces or specialty coatings, facility managers should always confirm chemical compatibility with the floor manufacturer before routine use of any walk behind floor scrubber machine.[web:9]

The SUNMAX RT35 walk behind floor scrubber is built with a user-friendly control panel and compact, walk-behind design so new operators can learn the basic functions with minimal training. Customers report that assembling and using the RT35 is straightforward and comparable to pushing a lawn mower, with brush-assisted movement that makes it comfortable to maneuver in commercial spaces. The included RT35 user manual provides step-by-step operating instructions, safety guidance, and maintenance procedures to support consistent results and help facilities standardize their cleaning protocols.

The RT35 walk behind floor scrubber series is rated for approximately 2–2.5 hours of continuous run time per full charge, depending on usage conditions and settings. With a coverage rate of 19,000 sqft/h, this gives enough battery capacity to clean large sections of schools, warehouses, or shopping areas before recharging. Charging time is about 8 hours for the RT35 lead-acid version and around 4 hours for the RT35+ lithium version, allowing overnight or mid-shift charging strategies to fit most janitorial schedules.

Routine maintenance for a walk behind floor scrubber includes emptying and rinsing the recovery (sewage) tank, cleaning the solution tank, inspecting and cleaning the brush and squeegee blades, and checking filters and hoses for debris after each use. SUNMAX notes that a small amount of water or green anti-freeze solution may be present in the RT35 tank or hose because each machine is fully tested with clean water before shipment, and this can simply be rinsed out before regular operation. The 2-year manufacturer warranty on the RT35, covering free replacement of non-wearable parts within the warranty period, encourages planned maintenance so facilities can rely on the machine for daily cleaning.

Industry buying guides show that walk behind floor scrubber machines are ideal for small to mid-size facilities and tighter spaces, while ride-on scrubbers are often used for very large open areas.[web:9] The SUNMAX RT35 offers 19,000 sqft/h productivity and a compact 17-inch cleaning path, allowing it to clean high-traffic areas, aisles, and corners where larger ride-on units may struggle, while still delivering commercial-grade performance at a lower purchase cost. For organizations that want Tennant-level results without premium pricing, SUNMAX positions its walk behind floor scrubbers as budget-friendly alternatives that maintain strong cleaning power and reliability.[web:11]

SUNMAX provides a 2-year manufacturer warranty on the RT35 walk behind floor scrubber, with free replacement of non-wearable parts within 2 years.

SUNMAX offers U.S.-based technical support, parts availability, and a detailed RT35 user manual, helping facilities keep their equipment running with minimal downtime.

Commercial cleaning resources consistently show that automatic floor scrubbers clean more effectively and efficiently than traditional mop-and-bucket methods, reducing labor time and leaving floors drier and safer to walk on.[web:9] With 19,000 sqft/h productivity, strong suction, and high brush pressure, the SUNMAX RT35 walk behind floor scrubber can cut cleaning time dramatically while improving hygiene and appearance in facilities such as gyms, schools, and warehouses. Many RT35 customers report that the machine “cuts cleaning time in half” compared with manual methods, allowing the equipment to pay for itself quickly through saved labor and rental costs.
