Walk-Behind Floor Scrubbers FAQ

What size walk-behind floor scrubber is best for my facility?

When choosing a walk-behind scrubber, match the cleaning path width and tank capacity to your space.

  • Under 10,000 sq ft (Cafes, Gyms, Shops):
    Choose the SM430 (17-Inch). With its dual 8.5" brushes and cordless lithium power, it's agile enough for narrow aisles and lightweight (only 50 lbs) for easy transport. Perfect for quick cleanups in tight spaces.
  • 10,000 - 40,000 sq ft (Warehouses, Schools, Clinics):
    Choose the RT50 (22-Inch). This is our workhorse. It covers 30,000 sq ft/hr with a larger 14.5-gallon tank, meaning you can clean for longer without stopping to refill. The ideal balance of size and power for most commercial facilities.
  • Over 40,000 sq ft (Factories, Large Distribution Centers):
    Choose the RT120 (34-Inch). This industrial beast features a massive 34-inch cleaning path and self-propelled traction drive. With a cleaning rate of 75,000 sq ft/hr, it does the work of two smaller machines, cutting your labor time in half.

Are walk-behind floor scrubbers easy to use for new staff?

Yes, walk-behind scrubbers (like SUNMAX RT50) are designed for simple, intuitive operation—just basic controls for brush, vacuum, and movement. Training usually takes only minutes, making onboarding fast and efficient for cleaning crews. Automatic features help prevent user error and increase productivity.

What types of floors can a walk-behind scrubber clean?

Walk-behind floor scrubbers can clean sealed concrete, tile, vinyl, epoxy, rubber floors, and even some low-pile carpets using the right pads. Models like the SUNMAX RT50 handle daily cleaning, spill recovery, and even ramps. Always confirm chemical compatibility for specialty surfaces.

How do walk-behind scrubbers compare to ride-on models?

Walk-behind scrubbers are more maneuverable in tight spaces and cost less up front. They're ideal for small–medium facilities, retail, and sites with lots of obstacles. Ride-on machines suit very large, open areas but cost significantly more. Many facilities use both for optimal coverage.

How long does it take to learn and maintain a walk-behind scrubber?

Most operators can learn to fully operate a SUNMAX walk-behind scrubber in under 30 minutes. Maintenance typically includes daily tank rinsing, pad or brush checks, and periodic battery charging or cable safety (for corded units). Instructions and training stickers are provided on the machines.

What cleaning chemicals work best with walk-behind scrubbers?

Use only non-foaming, neutral pH floor solutions designed for automatic scrubbers. Avoid excessively acidic or alkaline cleaners to protect both your floor and your machine. SUNMAX recommends Pro Neutral Cleaner or equivalent. Always follow the manufacturer's chemical guidelines for safety and best cleaning results.

How often should I replace the pads or brushes?

Pad and brush life depends on floor type and frequency of use, but most commercial users replace them every 3–6 months. Change sooner if cleaning results decline. SUNMAX offers easy-order accessories for all models.Shop replacement parts.

Can walk-behind scrubbers operate quietly in daytime hours?

Yes—modern SUNMAX walk-behind scrubbers run as quietly as 60 dBA, suitable for use in schools, hospitals, offices, and retail during work hours without disturbing people.

What is the warranty and support for SUNMAX walk-behind scrubbers?

All SUNMAX walk-behind floor scrubbers come with a 2-year limited warranty and tech support in the USA. Service help and parts are available nationwide for worry-free operation.
