Short Answer: Roomba Error 26 occurs due to insufficient airflow, often caused by a clogged or damaged filter. To fix this issue, clean or replace the filter, check for blockages in the brushes, and consider resetting the device.
Why Does Roomba Error 26 Occur?
Roomba Error 26 is an airflow-related issue that prevents the vacuum from operating correctly.
The airflow inside the Roomba must remain unobstructed to maintain proper suction and cleaning efficiency.
If anything disrupts this airflow, the Roomba will detect the problem and display Error 26.
While a dirty or damaged filter is the most common cause, other factors can contribute to this issue, such as blockages in the main brush, side brush, or even a malfunctioning head module.
Here Are The Key Causes of Roomba Error 26:
- Clogged Filter
- Blocked Brushes
- Damaged Head Module
- Obstructed Wheels
How to Fix Roomba Error 26
Fixing Roomba Error 26 requires a systematic approach, starting with the most common and straightforward solutions before moving on to more advanced fixes.
Below are the detailed steps to resolve this issue.
Step 1: Clean the Filter
A clogged filter is the most frequent cause of Roomba Error 26, making this the first area to address.
Even if you’ve recently cleaned the filter, it’s worth checking again, as dust and debris can accumulate quickly.
How to Clean the Filter:
- Remove the Dustbin: Press the release button to detach the dustbin from the Roomba.
- Extract the Filter: Locate the filter inside the dustbin and carefully pull it out.
- Shake Out Debris: Over a trash can, tap the filter lightly to dislodge dust and debris. If needed, use a soft brush to remove stubborn particles. Avoid washing the filter, as it’s not designed for contact with water.
- Reassemble: After cleaning, reinstall the filter into the dustbin and place the dustbin back in the Roomba.
Pro Tip: While you shouldn’t wash the filter, you can rinse the dustbin with cold water to remove any lingering dust. Ensure it is completely dry before reattaching it to the Roomba.
Step 2: Replace the Filter
If cleaning the filter doesn’t resolve Error 26, the filter itself may be worn out or damaged, even if it looks clean.
Filters are typically made from synthetic fibers or paper, and over time, they can lose their effectiveness.
How to Replace the Filter:
- Detach the Dustbin: Remove the dustbin from the Roomba.
- Remove the Old Filter: Take out the old filter and discard it.
- Install a New Filter: Insert a new, compatible filter into the dustbin. Ensure it’s securely in place to prevent air leaks.
- Reboot the Roomba: To reset the Roomba, press and hold the “Home,” “Dock,” and “Spot Clean” buttons simultaneously until the Roomba restarts.
Why Replace the Filter?
Even after thorough cleaning, filters can still harbor fine dust particles that the Roomba’s sensors detect, triggering Error 26. A fresh filter ensures optimal airflow and performance.
Pro Tip: Always use genuine iRobot filters to maintain compatibility and avoid issues with airflow. Non-genuine parts may not meet the same standards, potentially leading to further errors.
Step 3: Reboot or Factory Reset Your Roomba
If cleaning and replacing the filter don’t fix the issue, the next step is to reboot or factory reset your Roomba.
A reboot can clear temporary glitches, while a factory reset will restore the device to its original settings, eliminating any corrupted files that may be causing Error 26.
How to Reboot the Roomba:
- Press and Hold: Simultaneously press the “Home,” “Dock,” and “Spot Clean” buttons on your Roomba.
- Wait for Reboot: Continue holding the buttons until the Roomba powers down and restarts.
How to Factory Reset the Roomba:
- Access Settings: On the Roomba app, go to the settings menu.
- Select Factory Reset: Follow the on-screen instructions to reset the Roomba to its factory settings.
But Why Reset?
A factory reset can be particularly effective if the error is due to a software glitch or corrupted file within the Roomba’s system.
Important Note: A factory reset will erase all custom settings, including cleaning schedules and preferences. Ensure you back up any important data before proceeding.
Step 4: Replace the Head Modu
If all previous steps fail, the issue may lie within the Roomba’s head module. The head module contains the brushes and other components crucial for cleaning.
Over time, wear and tear can reduce its effectiveness, leading to Error 26.
How to Replace the Head Module:
- Remove the Dustbin: Detach the dustbin to access the screws securing the head module.
- Unscrew the Module: Use a screwdriver to remove the screws holding the head module in place.
- Replace the Module: Carefully remove the old head module and replace it with a new one.
- Reassemble: Reattach the screws, replace the dustbin, and test the Roomba.
Why Replace the Head Module?
A damaged head module can severely impact the Roomba’s ability to clean effectively, leading to airflow issues and triggering Error 26. Replacing it ensures the Roomba can perform at its best.
Pro Tip: If your Roomba is under warranty, contact iRobot Support before attempting any repairs. They may offer a free replacement or repair service.
Preventing Roomba Error 26
Prevention is key to avoiding future occurrences of Roomba Error 26. Regular maintenance and proper use can help keep your Roomba in optimal condition.
1) Regular Maintenance
- Clean the Brushes and Filter: Make it a habit to clean the brushes, wheels, and filter regularly. This simple maintenance routine can prevent blockages and ensure smooth operation.
- Inspect for Blockages: Regularly check the brushes and wheels for any debris that could obstruct movement or airflow.
You can schedule maintenance tasks in the Roomba app to ensure you don’t forget them.
2) Keep the Operating Environment Clean
- Clear the Floor: Ensure the area where your Roomba operates is free from small objects, cords, and clutter. These can get caught in the brushes or wheels, leading to errors.
Why It Matters: A clutter-free environment reduces the risk of sensor errors and blockages, allowing your Roomba to clean more efficiently.
3) Regular Software Updates
- Update Regularly: Keep your Roomba’s software up to date to benefit from the latest bug fixes and performance improvements. iRobot Software Update Page offers guidance on updating your Roomba.
This is because, software updates often include enhancements that can prevent errors like Error 26, improving the overall functionality of your Roomba.
