The Main Brush Roll in your iRobot Roomba 960 is responsible for agitating dirt and debris so it can be swept into the dustbin. Over time, the bristles on the brush roll will wear down, reducing its effectiveness. This results in less efficient cleaning and may even cause the Roomba to malfunction. Replacing the Main Brush Roll periodically ensures your Roomba continues to perform at its best.
