PowerBoss Scrubmaster B175 R Scrubber

The Scrubmaster B175 R provides floor scrubbing for large facilities, even on inclines, and features tons of accessibility designs to make maintenance and operation even easier than before.

For the cleaning of large facilities like airports, warehouses, industrial facilities, shopping centers, and fulfillment/distribution centers, the PowerBoss Scrubmaster is the machine for the job. It is designed for ease-of-use, with accessible parts, automatic brush-changing system, and built-in chemical dilution control. In the same vein, all of the functions on the control panel are performed at the push of a button. For example, activate Slow Mode for a focused and controlled 2.0 mph working speed, or show no mercy with the Boost Button, which activates maximum water flow and brush pressure. It’s powerful enough to get rid of tough soils, even on inclines, and agile enough for extremely tight turns.


  • Squeegee folds up manually for easy maintenance and daily cleaning
  • Large recovery tank opening makes it simple to clean
  • Brushes can be automatically ejected and installed. Changing the brush only takes a minute!
  • Flip up the seat for quick battery access.
  • Side skirts fold out sideways.

Three Sizes Fit All

The Scrubmaster comes in three main models which differ in cleaning width and scrub brush type.

Optional Features

As with all PowerBoss scrubbers and sweepers, the Scrubmaster can be customized with a wide variety of optional features according to your needs, such as:

  • PowerBoss Chemical on Demand: Cut chemical usage and operating costs at the press of a button, using chemical only when necessary on the toughest soils.
  • Pre-sweep Unit: This small sweeper attaches to the front of the Scrubmaster and collects solid debris, eliminating the need for time-consuming pre-sweeping with another machine. Plus, it’s easily removable if you only need to use it some of the time.
  • Spraying Nozzle: A spraying/suction tool and holder can be added to the rear of the machine for cleaning hard-to-reach areas, or cleaning the machine itself.
  • Many more!

We highly recommend using Bortek brand chemical products in this machine. Our cleaning solutions are made with scrubbers in mind, and designed to be low-foaming in order to prevent hazardous overflows.
