Walk Behind Floor Scrubbers for Commercial & Industrial Floors

Start with three numbers: total square footage cleaned per shift, the narrowest aisle or doorway your operator passes through, and whether power outlets are available along the route.

For routes under 10,000 sq ft with tight turns, a 14-inch model fits best. For 10,000–30,000 sq ft of open floor, a 17-inch model balances coverage and maneuverability. For routes above 30,000 sq ft, a 22-inch model reduces passes and labor hours.

If you're unsure, message SUNMAX with your floor size and layout — we'll point you to the model that fits before you order. Contact SUNMAX →

Commercial walk-behind floor scrubbers range from about $1,399 for a 14-inch corded compact unit to $4,699 for a 34-inch self-propelled model. SUNMAX prices factory-direct: a 22-inch battery RT50 is $2,499 and a corded RT50AC is $1,999. Price tracks cleaning width, power source, and tank size more than brand name.

A well-maintained commercial walk-behind floor scrubber typically lasts 5–8 years. Lifespan depends on run hours, floor abrasiveness, and upkeep — rinse tanks daily, check the squeegee blade, and replace brushes and pads on schedule. SUNMAX covers non-wear parts for 2 years and stocks replacement parts in Whittier, CA to extend service life.

Corded walk-behind scrubbers run on standard 110V power and never need recharging, which makes them a strong fit for retail back rooms, restaurants, and facilities where outlets are within a 25-foot radius.

Battery models (lead-acid or lithium) free you from the cord and work better in large warehouses, schools, and gyms where dragging a cord slows the operator down.

Lithium adds faster charging (around 3.5 hours) and lighter weight at a higher price point. SUNMAX offers both options in this collection so you can match the machine to your actual route, not the other way around.

Walk-behind scrubbers are the right call when your hard-floor area is under 50,000 sq ft per shift and your route includes turns, aisles, or obstacles. If your facility runs above 50,000 sq ft of mostly open floor, a ride-on scrubber usually pays back in operator hours saved.

If your main problem is dry debris — leaves, dust, packaging scraps — a floor sweeper handles that better than a scrubber. For carpet, low-pile rugs, or upholstered areas, you'll want a carpet extractor instead, since walk-behind scrubbers in this collection are built for hard floors only.

Most models in this collection ship with the core operating parts needed to start cleaning on day one, including the brush or pad holder and the squeegee assembly. Exact in-box contents vary by model, so check the individual product page before ordering.

Wear parts — brushes, squeegee blades, pad holders, and filters — are consumables that need replacement based on usage.

SUNMAX stocks replacement parts at our Whittier, CA warehouse so you can reorder without long lead times. Tell our team your model number and we'll match the correct part.

Shipping is free to the 48 contiguous states on every walk-behind floor scrubber in this collection. Machines ship by LTL freight from our Whittier, CA warehouse, with typical transit time of 3–8 business days after the order is processed.

We don't ship to Hawaii, Alaska, U.S. territories, or international destinations. For delivery questions, multi-unit orders, or facilities with limited dock access, contact us before ordering so we can flag delivery requirements with the carrier. Shipping policy →

The SUNMAX 2-year warranty covers non-wearable parts on the machine — items like motors, control panels, and structural components — against manufacturing defects from the original delivery date.

Wear parts (brushes, squeegee blades, pad holders, filters, batteries past their rated cycle life) are excluded because they're consumables. The warranty doesn't cover damage from misuse, modification, or use outside the intended commercial applications described on each product page. Full terms are on our warranty page.

Yes. SUNMAX support is handled directly through our team rather than a third-party dealer network. For setup and operation, every machine ships with a user manual and most product pages include a downloadable PDF.

For troubleshooting, send us your model number, order number, and a short description or photo of the issue — that's usually enough for us to identify the fix or the right replacement part. Replacement parts ship from our CA warehouse. Contact SUNMAX →

For freight damage, contact SUNMAX as soon as possible with your order number and photos of the packaging and machine — we'll handle the claim and replacement from there.

For sizing or fit issues, eligible orders can be returned within 30 days under our return policy. We'd rather help you pick the right model before you order than process a return after, so if you're between two sizes or unsure about power type, message us first with your facility details.
