Description
The brush, 18" .028 poly, supplied as Factory Cat part 19421P.
It measures 18 inches.
The .028 filament diameter sets how stiff the brush feels in use — thinner filament flexes into the floor surface, thicker filament scrubs harder.
Polypropylene filament is stiffer than nylon, holds its set when wet, and resists the chemicals used in floor care.
