iRobot Roomba 891 HEPA Filter Replacement
The HEPA Filter in your iRobot Roomba 891 traps dust, allergens, and other particles as the robot cleans. Over time, it gets clogged and less effective. Replacing the filter every two months ensures optimal cleaning performance and extends the life of your robot vacuum. Delaying replacement can lead to reduced suction power and potentially damage the motor.
