Steps to Clean the Vacuum: 1  Unplug the vacuum. 2  Remove and empty the vacuum canister or remove and replace the vacuum bag. 3  Clean the vacuum filter and rinse the canister with water if needed.  Straighten a wire hanger and use the hanger to poke through any clogs in the vacuum hose if needed.
Tips. 1  Go slowly as you pull vacuum towards you, because this is the cleaning part of the stroke. 2  Inspect the bottom of the unit and roller brush for over-sized debris that may be lodged and impeding airflow and suction. 3  Check to ensure that the bag or drum is not full; fullness greatly reduces air flow or sucking power.
