The HEPA filter in your iRobot Roomba 960 is crucial for capturing fine dust, allergens, and pet dander during cleaning. Over time, it accumulates debris and loses efficiency. Replacing the filter regularly ensures optimal performance and indoor air quality. Neglecting replacement can lead to reduced suction power, increased noise, and even potential damage to the robot's motor.
