This 13 inch blue brush is designed to fit our Powr-Flite® Crossover 26" ride-on floor scrubber. The brush is made from polypropylene and is good for everyday scrubbing on heavily soiled floors. The brush scrubs harder than the white version, so if you have a floor that scratches easy, please take a look at the white version. Please note, this brush is sold individually. The Crossover requires 2 brushes to operate so be to pick up two if you are replacing the pad driver on your 26" Powr-Flite auto scrubber. Floor scrubbing brushes outlast pads 100 to 1 and work better on cleaning uneven floors like tile, stone, and unfinished concrete.
