The Side Brush on your iRobot Roomba 675 is crucial for cleaning along edges and corners. Its three-arm design sweeps debris into the main brush path for efficient pickup. Over time, the bristles wear down, reducing cleaning effectiveness. Delaying replacement can lead to missed dirt and reduced overall performance.
