Primary Symptom: The robot vacuum is not moving or responding to commands.
Tools & Parts Required: Phillips #1 screwdriver, replacement wheel module (if needed)

Safety Warning: Power off the robot vacuum and remove it from the charging dock before attempting any repairs.

Why is my robot vacuum not moving?
If your robot vacuum is not moving or responding to commands, the most common cause is an issue with the wheels or wheel modules. Over time, the wheels can become stuck, worn out, or obstructed by debris, preventing the robot from moving properly.
- Power off the robot vacuum and flip it over to access the bottom panel.
- Remove the bottom panel by unscrewing the Phillips #1 screws.
- Inspect the wheel modules for any visible damage, debris, or obstructions.
- If the wheels are stuck or not spinning freely, try cleaning them with a soft-bristle brush or compressed air.
- If the wheels are worn out or damaged, you may need to replace the entire wheel module assembly.

What if my robot vacuum has sensor issues?
Another common problem with robot vacuums is sensor malfunctions, which can cause the robot to get stuck, miss areas, or behave erratically. The most important sensors to check are the cliff sensors, wall sensors, and object detection sensors.
- Power off the robot vacuum and remove it from the charging dock.
- Use a soft-bristle brush or microfiber cloth to gently clean the sensor lenses and windows.
- Check the sensor housings for any cracks or damage that could be interfering with their operation.
- If the sensors appear to be functioning properly, the issue may be with the robot’s navigation algorithms or mapping software, which would require a firmware update or reset.
How do I replace the battery in my robot vacuum?
Over time, the rechargeable battery in your robot vacuum will degrade and need to be replaced. This is a relatively simple DIY repair, but it’s important to follow the proper safety precautions.
- Power off the robot vacuum and remove it from the charging dock.
- Locate the battery compartment, which is usually accessible by removing the bottom panel.
- Carefully disconnect the battery connector and remove the old battery.
- Install the new replacement battery, making sure the connector is securely attached.
- Reassemble the robot vacuum and restore power to test the new battery.

Frequently Asked Questions
Will replacing parts void my robot vacuum’s warranty?
Performing basic maintenance and repairs, such as cleaning sensors or replacing worn-out parts, should not void your robot vacuum’s warranty, as long as you follow the manufacturer’s instructions. However, more extensive modifications or the use of non-OEM parts may void the warranty, so it’s best to check with the manufacturer before proceeding.
Can I use aftermarket parts for my robot vacuum repair?
While aftermarket parts can sometimes be a more affordable option, it’s generally recommended to use OEM (original equipment manufacturer) parts for your robot vacuum repair. OEM parts are designed specifically for your model and are more likely to fit and function properly, ensuring the long-term reliability of your device.
How often should I replace the filters and brushes on my robot vacuum?
Most robot vacuum manufacturers recommend replacing the filters and brushes every 6-12 months, depending on usage. Regularly maintaining these components can help keep your robot vacuum running at peak performance and prevent issues like reduced suction or uneven cleaning.
