SMALL REPAIR FORUM

Suddenly the main rolling brush of my Mi Robot Vacuum stopped working. It wasn't easy to diagnose.

First I noticed that most of the dirt was not getting picked up. Also, when stopping and starting the robot, the main brush would roll in the beginning and then it would stop. I thoroughly clean the brush of hair after every use, so was not sure what the problem was.

Then searching on the web, found that the bearing on one end of the roller is removable and hair/dust in it can jam the rotation.

Remove the end, clean it thoroughly, apply a little grease and refit it. Solves the problem.
