The yellow medium bristle brush is meant for rigorous scrubbing of carpets, tub and tile, and flooring. The bristles are stiff enough to dislodge old stains and they will hold up better than the soft carpet brush on heavy duty carpet. You can also use this brush on tiles, grout, and floor pads. It is used for general scrubbing and cleaning of carpets, door panels, RV's, and countless applications in the home. Recommended technique to use this power brush is to angle the brush to the surface to be cleaned (never use flat on a surface) and increase or decrease the angle as you clean.
