What if the vacuum cleaner chews the carbon brush?

Replace the carbon brush, repair the commutator and adjust the installation mode of the carbon brush.

1. Replace the carbon brush: the carbon brush is excessively worn and needs to be replaced with a new one. Select the carbon brush with the same specifications and models as the original factory to ensure the matching degree with the commutator.

2. Repair the commutator: the surface of the commutator is grooved or uneven and needs to be repaired. Grind with sandpaper or grinding wheel tool to restore flatness.

3. Adjust the installation mode of the carbon brush: the carbon brush is improperly installed, so it needs to be adjusted to ensure that the carbon brush is installed correctly and keeps good contact with the commutator.
