Since the early 1900s, Eureka has been manufacturing vacuums.When it's time to perform general maintenance on your vacuum, you will have to do it.Replacing your vacuum's drive belt is usually a part of this.You need to be able to partially dismantle your vacuum to perform general maintenance.Any major electrical repairs should be left to a vacuum repair technician.You could void your vacuum's warranty if you attempt repairs yourself.

Wrap the excess power cord around the cable-mounting holder on the side of the vacuum when you turn it off.

Determine if the vacuum has a disposable bag or a dirt holder.The dirt holder is held in place by the release button.The dirt holder needs to be removed and the contents emptied into a trash container.Pull the dust bag out of the vacuum and throw it away.

The air and dust filters are in the vacuum's housing.Most dust filters are secured to the vacuum by a single screw.You may be able to remove the filters from their individual compartment.Throw away the disposable filters and wash them with water.
