Fixing a confusing Henry Hoover fault.

Thought I would update, I bought the carbon brushes and when I went to replace them one side was ok the other was worn down to the point all that was left was inside the plastic. I used compressed air to clean the motor which had a lot of dust/carbon in it and since I have put these new carbon brushes in I have neither had any sparks and its always turned on first time regardless of where its plugged into.
