Description
The BISSELL Brush Block Bristles #1640377 (Cool Grey) is a genuine OEM replacement brush block for select BISSELL Little Green® Max Pet portable carpet cleaners. The brush block bristles agitate carpet fibers and upholstery surfaces to loosen embedded dirt, pet hair, and debris, driving it into the suction path for a deeper, more thorough clean. Worn or matted bristles significantly reduce cleaning effectiveness — replacing the brush block with BISSELL part 1640377 restores your machine's full scrubbing and pickup performance.
Why Replace Your BISSELL Brush Block Bristles?
