Our 2-1/2" Round Brush Tool makes cleaning easier by agitating, releasing, and cleaning hard-to-get material from surfaces. The soft bristles will not mar or scratch surfaces, allowing you to clean quickly without causing damage to finished surfaces. The red color indication ring allows for quick size identification of its 2-1/2” diameter. This round vacuum cleaner brush is compatible with MILWAUKEE® 2-1/2" Vacuum Hoses (49-90-2004, 49-90-2006) and other 2-1/2" diameter vacuum hoses.
