Walk-Behind Floor Scrubber Buying Guide

In this section, we’ll teach you everything you ever need to know about walk-behind floor scrubbers, including determining whether you need one and how to find the ideal model for your building.

What Is a Walk-Behind Floor Scrubber?

The tool’s name is pretty self-explanatory. If you’re unaware, floor scrubbers are deep-cleaning tools used on hard floors (tiles, laminate, concrete). They come with powerful motors that move their wide brushes at high speeds to scrub the stubbornest stains away.

A walk-behind floor scrubber is the second-most powerful type of floor scrubber—stronger than uprights but less powerful than riding floor scrubbers. As such, they deliver extraordinary amounts of downward pressure to loosen and remove caked-on stains in just one or two passes. These tools are ideal for buildings with between 10,000 and 100,000 square feet of hard floors.

How to Choose the Best Walk-Behind Floor Scrubber

Below, we’ll briefly go over the various specs and features you need to consider when shopping for the best walk-behind floor scrubber for your business.

Brush Type, Size, and Speed

One of the most crucial variables to consider is the brush. Take a look at the brush to determine its type, size, and how quickly it rotates or oscillates. The types of brushes and pads available are disc-shaped (like in the models on our list) and rectangular shaped. The size of the brush refers to how wide of a path the floor scrubber cleans with every pass. As for the speed of the brush, anything over 150 RPM would serve you well.


A walk-behind floor scrubber’s brush or pad pressure is typically measured in pounds. A higher pressure rating is indicative of a harder-working scrubber that can remove greasy stains or caked-on messes in fewer passes. Ideally, you should look for a model that delivers at least 50 pounds of pressure. Some of the best models let you adjust the downward pressure of the brushes on demand.

Water Tanks

Walk-behind floor scrubbers come with two tanks—a clean water tank and a recovery tank. The clean water tank holds onto a solution of clean water and your choice of floor detergent. As for the recovery tank, the water used to clean your floors is suctioned and stored in this tank, dirt and all. Larger water tanks allow you to work for longer with fewer refill disruptions.

Squeegee Shape

The squeegee sits behind either the brush or behind the tool’s rear wheels, the latter being the case in the SUNMAX. The most important thing to consider regarding the squeegee is its shape. Make sure that the squeegee is semi-circular in shape and not straight as it might end up pushing dirty water to the side.


1. How do walk-behind floor scrubbers work?

Using a walk-behind floor scrubber is pretty straightforward. The tool automatically saturates the brush or pad in the clean-water solution. The pads rotate at high speeds to scrub dirt and hard-to-remove stains off of hard floors. Finally, a built-in suction system pulls in the polluted water and stores it in the recovery tank for later disposal.

2. Should I get a walk-behind floor scrubber for my home?

Probably not, unless your home takes up more than 10,000 square feet of land. For the most part, homeowners can get by with an upright floor scrubber or even a steam mop. A walk-behind floor scrubber is the ideal cleaning tool for large establishments with lots of foot traffic.

3. How often should I clean my floors with a walk-behind floor scrubber?

The frequency at which you should deep-clean your hard floors depends on how dirty your floors get. Don’t neglect regular cleaning rituals like dusting, vacuuming, and mopping. Most places that use walk-behind floor scrubbers (hospitals, hotels, warehouses) use them every one to two weeks.


4. Is corded better than cordless?

It ultimately boils down to whether you value maneuverability more than performance. For the most part, corded walk-behind floor scrubbers deliver greater amounts of pressure. On the other hand, cordless floor scrubbers are great if you have several backup batteries on hand. On average, a single charge can deliver up to 180 minutes of continuous cleaning.
