Floor Scrubber Size Recommender: Find the Right Machine Class

How the recommendation is made

The tool calculates the practical cleaning rate you need (area divided by hours), then checks each machine class in order from smallest to largest. It recommends the smallest class that meets the rate and fits your narrowest aisle, because smaller machines cost less, are easier to store and maneuver, and are what operators will actually use.

Class	Typical path	Working speed	Approx. body width
Micro scrubber	15 in	100 ft/min	18 in
Small walk-behind	20 in	175 ft/min	24 in
Mid walk-behind	26 in	175 ft/min	30 in
Large walk-behind	32 in	175 ft/min	36 in
Stand-on	28 in	250 ft/min	32 in
Ride-on	32 in	300 ft/min	38 in
Large rider	40 in	320 ft/min	50 in
Industrial rider or sweeper-scrubber	50 in	350 ft/min	62 in

Body widths are representative only, and squeegees are usually wider than the scrub path, so measure the actual machine before you buy. For the full reasoning, read floor scrubber size by square footage and walk-behind vs ride-on.

Frequently asked questions

What size floor scrubber do I need for 10,000 sq ft?

If you have about an hour, a 17 to 20 inch walk-behind is usually enough. With only 30 minutes, step up to a 26 to 28 inch walk-behind.

When does a ride-on make sense?

Riders usually pay off once a single shift covers more than about 40,000 to 60,000 sq ft of fairly open floor, or when operator fatigue on long walk-behind runs becomes a problem.

Why recommend the smallest machine that works?

Oversized machines cost more, struggle in tight spaces and often end up parked while staff go back to mops. Matching the class to the real job gets the floor cleaned.

Does the squeegee need to fit through doors too?

Yes. Squeegee assemblies are often several inches wider than the scrub path. Check overall width with the squeegee fitted against your narrowest doorway, and leave room to steer.
