CRB Brush Selection Guide

CRB brushes are color-coded to help determine the proper stiffness and surface application. Selecting the correct brush improves cleaning performance while protecting carpet fibers and hard surfaces.

Brush choice is determined by surface type and cleaning objective — not by machine model. All CRB machines accept brush sets sized to the machine width (12", 15", or 20").

Wear Indicator: Certain CRB brushes include colored bristle strands that serve as wear indicators. As the brush wears down and the indicator becomes visible, it signals that the brush should be replaced to maintain optimal cleaning performance.
