Fortunately, this is an issue that most users can resolve themselves with a bit of guidance. This article serves as your comprehensive guide to diagnosing and fixing airflow problems with your Roomba 880. We will walk you through identifying the symptoms and causes, provide step-by-step cleaning instructions for critical components, and offer proactive maintenance tips. By following these steps, you can restore your Roomba’s performance and prevent future interruptions.
What Triggers Roomba 880 Error 26?
Â
When your Roomba 880 displays “Error 26,” it is signaling a specific problem: the airflow within its vacuum system is blocked. This obstruction prevents the machine from creating the suction necessary to pick up dirt and debris effectively. Promptly addressing this error is crucial for maintaining your device’s cleaning efficiency and operational longevity.
Key Symptoms of an Airflow Blockage
You’ll know you have an airflow problem if you observe one or more of the following signs:
- Sudden Stops: The Roomba halts its cleaning cycle and returns to its Home Base prematurely.
- Atypical Noises: The vacuum may sound strained, louder, or different than usual as it struggles to pull air through the system.
- Reduced Cleaning Power: You notice that the Roomba is leaving behind dirt and debris it would normally pick up.
- Error Message: The device’s top-mounted display clearly shows “Error 26.”
Frequent Causes of Obstructions
The blockage is almost always caused by an accumulation of debris in one of three key areas:
- Clogged Filter: The HEPA filter is designed to trap fine dust and allergens. Over time, it can become saturated with hair and dust, severely restricting airflow.
- Blocked Airpath: Debris can get lodged in the air intake or exhaust ports, creating a bottleneck that chokes the vacuum’s suction.
- Tangled Brush Roll: The main brush roll is highly susceptible to getting tangled with hair, strings, threads, and other fibrous materials, which can prevent it from spinning freely and block the suction channel.
A Step-by-Step Guide to Fixing Airflow Obstructions
Resolving Error 26 typically involves a systematic inspection and cleaning of the Roomba’s core components. Follow these detailed steps to locate and clear the blockage. Before you begin, ensure the Roomba is powered off.
Step 1: Inspect and Clean the Filter
The filter is the most common culprit behind airflow errors.
- Locate and Remove: The filter is located inside the dustbin. Press the release button to remove the bin from the Roomba. Open the bin door to access the filter and pull it out.
- Inspect Thoroughly: Look for a thick layer of dust, embedded hair, or other debris covering the filter’s surface.
- Clean the Filter: Vigorously tap the filter against the inside of a trash can to dislodge most of the debris. Use a soft brush or a handheld vacuum to remove any remaining fine dust. If your filter is washable, you can rinse it under cool water.
- Dry Completely: If you washed the filter, it is critical that it is 100% dry before you reinstall it. A damp filter can lead to mold growth and damage the vacuum motor. Allow it to air dry for at least 24 hours.
- Reinsert: Once clean and dry, place the filter back into the dustbin and slide the bin back into the Roomba until it clicks into place.
If your Roomba’s filter is heavily clogged, damaged, or has reached the end of its lifespan, replacing it is crucial for maintaining optimal airflow and cleaning performance.

Step 2: Clear the Primary Airpath
If a clean filter doesn’t solve the problem, the blockage may be in the air channels.
- Empty the Dustbin: First, ensure the dustbin is completely empty, as an overfull bin can contribute to poor airflow.
- Examine the Air Intake: With the dustbin removed, look into the cavity where the bin sits. This is where the air intake is located. Use a flashlight to check for any lodged debris and manually remove anything you find.
- Check the Exhaust Port: Inspect the exhaust vents on the Roomba for any visible obstructions and clear them out.
- Use a Tool if Needed: For stubborn debris caught deep inside the airpath, a small, flexible brush or a compressed air canister can help dislodge the blockage.
Step 3: Examine and Untangle the Brush Roll
A tangled brush roll not only stops cleaning but can also create a physical barrier to airflow.
- Access the Brush Roll: Flip the Roomba over. Locate the brush roll guard (usually a yellow or gray frame) and lift the two release tabs to remove it.
- Remove the Brushes: Lift out the main brush rolls.
- Cut Away Tangles: Carefully use scissors or the included cleaning tool to cut away any hair, string, or fibers wrapped around the brushes and their yellow bearings.
- Clean the Bearings: Pop the yellow bearings off the ends of the brushes and clean out any hair that has accumulated underneath them.
- Reinstall and Test: Place the clean brushes back into the Roomba, ensuring they are seated correctly. Re-attach the brush guard and manually spin the brushes to confirm they move freely.
If your Roomba’s brush rolls are worn, damaged, or severely tangled beyond effective cleaning, replacing them can restore proper agitation and prevent airflow obstructions.

- Restart a Cycle: Place the Roomba back on its Home Base to let it recharge fully, then start a new cleaning cycle to see if the error has been resolved.
Proactive Maintenance for Your Roomba 880
The best way to deal with Error 26 is to prevent it from happening in the first place. Consistent maintenance ensures your Roomba operates at peak performance and extends its lifespan.
Establish a Regular Cleaning Routine
- Filter: Clean the filter at least once a week, or after every few cleaning cycles in homes with pets or high traffic. Replace the filter every 2-3 months.
- Brush Rolls: Inspect the brush rolls weekly. Remove any accumulated hair or debris from the brushes and their bearings.
- Side Brush: Check the side-mounted flailing brush for tangles and wipe it clean. If it becomes bent or worn, replace it. You can unscrew it with a small screwdriver.
