The Brush Roll Kit in your iRobot Roomba 675 is responsible for picking up dirt, debris, and pet hair. Over time, the bristles wear down and become less effective at cleaning. Replacing this kit every 6-12 months ensures optimal suction and cleaning efficiency. Delaying replacement can lead to reduced cleaning performance and potential strain on other parts of your Roomba.
