The HEPA Filter in your iRobot Roomba 675 traps dust, allergens, and other microscopic particles, ensuring cleaner air while the robot vacuums. Over time, the filter clogs up, reducing suction power and airflow. Replacing it regularly maintains optimal performance and extends the life of your device.
