Why the abnormal noise occurs while the robot is cleaning?

1. Turn the robot vacuum over,

2. Remove the roller brush cover and roller brush.

3. Then turn on the robot to see if there is any abnormal noise. If the sound disappears, it is the problem of a roller brush. If that is the case, I'll send you the accessories.
