Check for Obstructions
- Turn the Roomba over and locate the side brush, which is usually situated on the machine's underside.
- Look for any debris, hair, or string that might be tangled around the side brush. These can stop the brush from spinning.
- Carefully remove any obstructions using your fingers or tweezers if necessary. Be gentle to avoid damaging the brush or the Roomba.
Inspect the Side Brush and Assembly
- Unscrew the side brush using a screwdriver (usually a Phillips-head is required). Newer models may have a yellow side brush cover that can be easily removed by hand.
- Examine the brush and its spindle for any unusual wear or damage. If the brush bristles are bent or worn out, consider replacing it with a new side brush.
- Inspect the area underneath the brush for additional debris or damage. This is where dirt can accumulate, affecting performance.
Clean the Brush Motor Assembly
- With the side brush removed, take a look at the brush motor assembly. Dust, dirt, or debris here can also cause issues.
- Clean the motor assembly gently. Avoid using water to prevent damaging the electronic components. A dry or slightly damp cloth can help.
- Check the gear rotation by hand; it should spin smoothly. If it doesn’t, there might be issues with the motor that warrant a professional repair or replacement.
Reattach and Test
- Once everything is checked and cleaned, reattach the side brush securely using the screw.
- Power on the Roomba to ensure that the side brush is spinning correctly. It should move freely without any hitches.
- Perform a test run in a small, controllable area to see if the issue is resolved.
Consider Possible Software Issues
- Sometimes, the problem might not be mechanical but rather a software glitch. Restarting the Roomba can sometimes fix such issues.
- If a restart doesn’t solve the problem, check if there’s a firmware update available for your model. Updating the firmware can help resolve bugs or glitches affecting the side brush operation.
When to Seek Professional Help
- If the side brush still doesn’t work after trying these steps, there might be a deeper issue, possibly with the motor or electrical components.
- Seeking a professional repair service or contacting iRobot support would be advisable to address the problem effectively without causing further damage.
