There are metal spring clips that hold the stator firmly in place, if you press down on the clips, the stator should be able to slide out with relative ease. You have to be careful while doing this as the stator has electronic controller wiring attached to it.

It is essential to clean up dirt and debris from the inside of your stator to ensure that your vacuum cleaner operates at its optimal working levels. Be cautious while removing the rotor assembly as it has bearings at both ends but don’t forget to Ensure that you do not lose any washers in the process. 

At the rotor's ends there is a commutator, and if the commutator gets dirty or looks compromised, this may affect your vacuum cleaners' performance. You have to mount the commutator on a mini-lathe To fix it as an alternative use both wet and dry sandpapers. 

Try using light, feathery strokes to sand down the commutator's ends. Replace the bag and all the filters in the vacuum cleaner and make sure that all the intake and output airways are clean and bright.

Repair the Electronic Gears:

The cleaners usually have a primary electronic system and typically is consists of a trick with a rating of between 20-30 Amperes and a thermal cutout device. 

Don’t forget to check that there are no loose electrical connections. Make sure that the plastic clips that hold the electrical connectors together are not cracked or damaged to ensure safety.

If you find any lose connection, ensure that you replace them and insulate the area. When you turn vacuum cleaner on, and it does not work, it might be the fuse.

Then you have to check that the fuse is intact. If it is not, then replace the fuse and when you do this- check to see if the connections in the plug are okay.
