The Milwaukee 1-7/8" Floor Brush Tool (49-90-1982) makes cleaning faster by agitating, releasing, and cleaning hard-to-get material from flat surfaces. The bristles will not mar or scratch surfaces, allowing you to clean quickly and effectively without causing damage to finished surfaces. The Floor Brush Tool has reversible bristles, allowing you to clean more effectively in either forward or backward strokes. The gray color indication ring allows for quick size identification of its 1-7/8” diameter.
