Your vacuum cleaner doesn't need very much attention, but a little simple maintenance will keep it working and cleaning as efficiently as it can. Maintaining your vacuum cleaner properly can also head off more costly repairs or replacement.
Unplug your vacuum cleaner before performing any maintenance on it. A vacuum cleaner that turns on unexpectedly while you are working on it can injure you.Check to make sure your vacuum has a ground prong. If this is missing, DO NOT USE the vacuum. Contact your lead custodian for repair.
