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.
For larger blockages, use a wet-vac or air compressor to remove the blockage. If using a wet-vac, suction can be applied to either end of the drain line to remove the clog. If using an air compressor, see step 3. 2. If the cleaning solution or water fills up the drain a wet-vac can be used to remove the fluid. Repeat pouring of cleaning solution down PVC drain line, if necessary.
