What should I do if my Shark vacuum is not picking up debris or has reduced suction?

First, empty the Dust Cup if it is full by pressing the Dust Cup Release Button and then the Dust Cup Empty Button over a trash receptacle. Then clean the Post Motor Filter by removing it from the Handheld Vacuum, rinsing under cold water until clear, and allowing it to dry completely before reinserting. You should also check for blockages in the nozzle, hose, or filters and remove any obstructions.
