Combines nylon brushes, which flex the carpet pile to lift deep-seated dirt, along with a thick absorbent bonnet to remove loosened dirt from the surface. The "four-leaf clover" design assures that both brushes and bonnet extend to the edge of the block.
The BONNET-LOK™ System is a brush/bonnet combination in a single unit. The exclusive design allows both the brush and the bonnet to extend to the wall for maximum coverage and effectiveness.
