Malish 14" Nylon Carpet Shampoo Brush, Plastic Block - 812914, formerly COM-802

The best quality brush for this application. Nylon is flexible and supple enough to gently scrub carpets, yet has more “memory“ than other fibers for a longer lasting brush. No break-in process required. On brushes 14" in diameter and larger, the two outer rows are heavier to scrub the carpet and flex the pile while the softer inner rows “massage” the dirt from the carpet for a deeper cleaning action.
