What should I do if my vacuum loses suction while cleaning?

First, empty the Dust Cup if it's full by pressing the Dust Cup Release Button and holding it over a trash receptacle. Then clean the Post Motor Filter (G) by rinsing it under cold water until the water runs clear and allowing it to dry completely before reinserting. If suction remains low, check for blockages in the nozzle, hose, or filters and remove any obstructions. [Page 1]
