Floor scrubbers wash, scrub, and dry hard floors in one pass so a kitchen or warehouse does not have to mop by hand, and the spec that decides whether yours earns its storage space is cleaning width and tank capacity. What you are buying is square feet per minute, minus the mop bucket. Cleaning width. Solution tank. Brush type. Power source. Here is what separates the machines that keep a big floor presentable from the ones that become expensive storage. As one facilities manager put it: "A floor scrubber does not clean a floor. It deletes it."

What Actually Matters When You Compare Floor Scrubbers
Cleaning width: The scrub deck width sets how much floor you cover per pass. 13-inch machines suit kitchens and small shops; 22-inch walk-behinds cover warehouses and retail. Width is productivity.
Solution and recovery tanks:Clean solution capacity sets run time, and recovery tank size decides how long before you empty. Bigger tanks mean fewer stops. Tanks are endurance.
Brush or pad type:Rotary brushes scrub grout and texture; pad drivers clean and polish hard floors. Some decks handle both. The brush decides the finish.
Power source:Corded electric machines run forever with an outlet nearby; battery walk-behinds work anywhere on the floor. Power source is range.

What is the difference between a floor scrubber and a floor buffer?
A floor scrubber applies solution and scrubs grime, often with recovery. A buffer polishes and burnishes an already clean floor. Scrubber cleans. Buffer shines.
Can a floor scrubber work on any floor type?
Hard floors are the target: tile, concrete, vinyl, and sealed wood. Carpet needs a dedicated extractor or carpet head. Match the machine to the floor.
How often should I scrub a commercial floor?
High-traffic kitchens and entrances typically need daily or weekly scrubbing; lower-traffic areas can go monthly. Traffic sets the schedule.
