Maintenance Guidelines
Regular maintenance is crucial for your Roomba robot to maintain its cleaning efficiency. Using genuine iRobot parts is essential to ensure compatibility, optimal performance, and to maintain your product's warranty.
1. AeroForce High-Efficiency Filters
These filters are designed to capture fine dust and debris, preventing them from recirculating into your home's air. A dirty filter can significantly weaken your robot’s suction power.
- Recommended Replacement: Every 1 to 2 months, or more frequently depending on usage and pet presence.
- Replacement Procedure:
- Open the dustbin compartment on your Roomba.
- Remove the old filter by pulling it out.
- Insert a new AeroForce High-Efficiency Filter into the dustbin.
- Close the dustbin compartment securely.

2. Edge-Sweeping Brushes
These brushes are specially designed at an angle to sweep debris from edges and corners directly into the robot's cleaning path. Worn brushes are less effective at collecting debris.
- Recommended Replacement: Every 3 to 6 months, or when visibly worn or damaged.
- Replacement Procedure:
- Using a small screwdriver, unscrew the retaining screw on the old edge-sweeping brush.
- Remove the old brush.
- Place the new edge-sweeping brush into position and secure it with the screw.

3. Multi-Surface Rubber Brushes (Extractors)
The AeroForce Extractors are designed to flex and maintain constant contact with carpets and hard floors, effectively lifting dirt and debris. Worn extractors will reduce cleaning effectiveness.
- Recommended Replacement: Every 6 to 12 months, or when cleaning performance decreases or brushes show significant wear.
- Replacement Procedure:
- Open the brush frame on the underside of your Roomba.
- Remove the old multi-surface rubber brushes.
- Insert the new brushes, ensuring they are correctly aligned.
- Close the brush frame securely.
