Main brush error

I’m getting this error message. I have cleaned the brush even went ahead. Bought a new brush and replace it and it’s still giving the error message start cleaning for like three seconds and then it gives out the error message when you send it to go home it goes halfway and give the error message. I have cleaned the whole robot. Can’t seem to find the issue. Can somebody help?

Which robot is it?

Hi,

Please follow the steps below to check whether the main brush is normal:

1. Check the main brush:
- Please remove the main brush cover first, then take out the main brush, check and clean the entanglement on the main brush.

2. Check the rotation of the main brush:
- After cleaning, please reinstall the main brush and check whether it rotates smoothly by hand.

3. Ensure that it is installed in place:
- When reinstalling the main brush, make sure that the main brush cover is in place around to ensure its normal use.

4. Restart the robot:
- If no entanglement is found after checking the main brush, please guide the user to manually restart the robot and restart the cleaning task. Observe whether the error still occurs.

5. Upgrade the robot firmware to the latest version.

If the issue remains unresolved after completing the above steps, please contact support.na@dreame.tech for further investigation and assistance.
