Who it fits

Key specs explained for you

15" Cleaning Width

This measurement defines the physical footprint of the scrubbing brush as it moves across the floor. A 15-inch width allows you to cover a moderate path with each pass. It balances coverage speed with maneuverability in aisles or around obstacles. You will find this size practical for medium-sized commercial spaces like retail stores or small warehouses where tight turns are common.

5 gal clean, 6 gal recovery

The machine holds five gallons of fresh water for scrubbing and six gallons for dirty water extraction. Separate tanks prevent cross-contamination, ensuring you apply clean solution while removing grime efficiently. This capacity reduces how often you must stop to refill or empty the unit. It supports continuous operation in large areas like garages or hospitals without frequent interruptions.

380 W brush, 500 W suction

These power ratings indicate the energy used for mechanical scrubbing and water extraction. The 380-watt brush motor provides torque to agitate dirt from surfaces like concrete or tile. The 500-watt suction motor pulls the dirty water into the recovery tank. Together, they ensure thorough cleaning and immediate drying, which is essential for high-traffic commercial environments where slip hazards must be minimized.

23" Suction Width

The squeegee assembly is 23 inches wide, which is wider than the 15-inch scrubbing path. This design allows the machine to capture the entire wetted strip in one pass. It ensures no clean water is left behind after the brush has scrubbed. This wider suction path improves efficiency and helps maintain a consistent, streak-free finish on floors such as epoxy or terrazzo.

Design and build overview

The unit measures 29.5 inches in length, 16.9 inches in width, and 40.9 inches in height. It weighs 178 pounds. This mass provides stability during scrubbing but requires effort to move. The listing notes a folding handle design. This feature reduces the storage footprint when the machine is not in use. Two operators can lift and load the unit into a standard vehicle for transport.

The body is finished in blue. The control panel is described as intuitive with a one-touch start mechanism. This layout allows staff to operate the machine with minimal training. The compact build suits environments like warehouses, garages, and retail stores. It is designed for commercial use on surfaces such as concrete, tile, and epoxy.

According to the listing, the 15-inch scrubbing width and 23-inch squeegee suction width define the cleaning path. The separate tanks hold five gallons of clean water and six gallons of recovery water. This capacity reduces the frequency of stops for refilling and emptying. The design prioritizes continuous operation in high-traffic areas. The materials and dimensions support efficient workflow in commercial settings.

Setup and daily operation workflow

You begin by filling the separate tanks. The clean water tank holds five gallons. The recovery tank holds six gallons. This separation keeps your solution fresh and your dirty water contained. The unit weighs 178 pounds. You will need to lift it into a vehicle for transport. The folding handle design reduces the storage footprint, making this manageable for two people.

Once powered on, you use the one-touch start mechanism. The control panel is intuitive, requiring minimal training for your staff. The 380-watt brush motor engages the 15-inch scrubbing width. Simultaneously, the 500-watt suction motor activates. This motor pulls water through the 23-inch squeegee suction width. The result is immediate drying on compatible surfaces.

You can operate this machine on concrete, tile, marble, epoxy, PVC, emery, terrazzo, and sealed hardwood floors. The listed cleaning efficiency is up to 24,000 square feet per hour. This rate depends on your speed and the level of soiling. The larger tank capacities mean you refill less often. This is useful in large warehouses or retail spaces. You simply push the unit behind you. The scrubbing head cleans while the suction extracts the solution. The straightforward design allows for quick start and stop during routine shifts.

Before You Buy This Scrubber

This unit targets large commercial spaces. You need floors like concrete, tile, or epoxy. Sealed hardwood works too. Avoid rough surfaces that damage brushes. The machine weighs 178 pounds. You must have staff to lift it into vehicles. The folding handle helps, but two people are required. Check your water source. You need access to fill the five-gallon clean tank. You also need a drain for the six-gallon recovery tank. Maintenance involves cleaning the squeegee and brushes. Debris clogs the suction motor quickly. Compare this to ride-on models. Those cover more ground but cost more. This walk-behind fits smaller warehouses or retail aisles. It suits teams already using manual mops. Upgrade only if daily square footage exceeds manageable limits. Ensure your staff can handle the weight. The controls are simple. One-touch start reduces training time. This makes it easy for rotating shifts.

Check before you buy

• Verify floor type matches concrete, tile, or epoxy.
• Confirm you have two people to lift 178 lbs.
• Check water access for filling the five-gallon tank.
• Ensure drain access for the six-gallon recovery tank.
