2. Setup and Installation
Installing the iRobot Dirt Disposal Bag is a straightforward process. Ensure your robot's dock is powered off or unplugged before proceeding with the installation or replacement of the bag.
Installation Steps:
- Locate the Dock Compartment: Identify the dirt disposal compartment on your AutoEmpty™ or AutoWash™ Dock. This is typically a hinged lid or a removable panel.
- Open the Compartment: Open the compartment door or remove the panel to access the bag housing.
- Remove Old Bag (if applicable): If replacing an existing bag, carefully pull the full bag upwards and out of the housing. The bag's opening mechanism is designed to seal automatically upon removal, preventing dust from escaping. Dispose of the full bag responsibly.
- Insert New Bag: Take a new iRobot Dirt Disposal Bag from the pack. Align the bag's cardboard collar with the slot in the dock's housing. Push the bag firmly down until it clicks securely into place. Ensure the bag is fully seated and the opening is properly aligned with the dock's suction port.
- Close Compartment: Close the compartment door or replace the panel. Ensure it is securely latched.
- Power On: Reconnect power to your dock if it was unplugged. Your Roomba system is now ready for operation with the new dirt disposal bag.

3. Operation
Once the dirt disposal bag is correctly installed, the operation is automatic. When your Roomba robot returns to its compatible AutoEmpty™ or AutoWash™ Dock after a cleaning cycle, the dock will automatically empty the robot's dust bin into the installed dirt disposal bag.
This automated process ensures that your robot is ready for its next cleaning task without manual intervention for dust bin emptying. The bag's design prevents dust and debris from escaping during the emptying process and when the bag is removed for disposal.
4. Maintenance and Replacement
Regular replacement of the dirt disposal bag is essential for maintaining the performance of your iRobot Roomba system and preventing clogs in the dock's emptying mechanism.
Replacement Schedule:
- It is recommended to replace the dirt disposal bag approximately every 75 days. This duration may vary based on factors such as pet hair, frequency of cleaning, and the overall dirtiness of your environment.
- Your dock or the iRobot HOME App may provide notifications when the bag is full and requires replacement.
Disposal of Used Bags:
When removing a full bag, the bag's opening automatically seals to contain dust and allergens. Simply pull the bag out of the dock and dispose of it in your household waste. No direct contact with dirt or dust is required.
5. Troubleshooting
While dirt disposal bags are passive components, issues can arise if they are not properly installed or replaced.
| Problem | Possible Cause | Solution |
|---|---|---|
