Abstract
A vacuum cleaner having a filter cleaning mechanism that is manually actuable while the vacuum cleaner is fully assembled is disclosed. A housing of the vacuum cleaner has an exterior side and an interior side, and a channel extends through the housing from the exterior side to the interior side. A filter brush is in contact with a side of the vacuum filter, and a rod extends slidably through the channel in the housing and is coupled to the filter brush. A handle is coupled to the rod, and movement of the handle slides the rod through the channel and moves the filter brush along the side of the vacuum filter to remove debris from the filter. The handle may be rotatable, and the filter cleaning mechanism may include a bellows or a sealing member.
