Re: Hoover Vac:
This sounds like the same Vac that I've got, as part of my Vac Collection. They called that "Box-Shaped" Vac a "Hat-Box" Vac. Is yours a 2-Tone Green or Gold/Yellow Color? Mine is the 2-Tone Green Color. Have you checked all of the Part's out? It might have something clogged in either the Rug/Floor Nozzle or even possibly in the Flex Hose or the Wands. Is it also possible that the Bag is full, not allowing proper Suction? If you have another Vac that has a Blower {no pun's intended} area, place the Flex Hose against the opening of the Hose of the other Vac and Blow any obstructions out, as well as seeing if you can take the Floor/Rug Brush apart to see if it might have something clogging an area of it that isn't visible, without taking it apart. If the Flex Hose isn't able to be disconnected from the Unit, then use the Suction of your other Vac to pull any obstruction's out of the Flex Hose. "Good-Luck" with getting the Vac operating good again.
Peace and Happy Vacuuming, Steve
