This 20" prolene polypropylene brush for the Advance SC1500 floor scrubber is a medium duty brush, good for everyday scrubbing on surfaces like terrazzo, concrete or vinyl floor tiles. A prolene brush is much like using a red or a blue pad but comes with the benefit of a longer lifespan that brushes give (Brushes normally outlasts pads 100 to 1). A good option for removing dirt and scuff marks from hard floors during daily scrubbing.
