The Filter in your iRobot Roomba s9 traps dust, dirt, and allergens, keeping your floors clean and the air you breathe fresher. Over time, the Filter becomes clogged, reducing suction power and overall cleaning efficiency. Replacing it regularly ensures your Roomba continues to perform at its best. Delaying replacement can lead to reduced performance and potentially damage other components.
