Why Is My Vacuum Cleaner Smoking?
Remove hair, lint and other debris from the brush roller. Empty the vacuum bag or tank before it is completely full. Replace your air filter at least once a year. If your vacuum uses a HEPA filter, replace it every six to eight months. If you are using a canister vacuum, empty the canister before it is completely full. Depending on your vacuum model, you may need to empty it two to three times a year.
