What's wrong with it.I changed the bag and dug everything out of the bottom, got a bunch of stuff out but it still isn't working?
Sounds like your vacuum is clogged remove the hose and see if you have air flowing
Maybe the beater brush isn't turning or the passage in the power head is clogged. Try removing the power head from the pipe and looking down into it to see if you can see light (or the clog). If the power head isn't clogged, maybe the pipe or hose has something jammed. Try turning it around and place it up to the suction port backwards, turn the vacuum on and see if it will pull it out that way. An old trick on vacuum cleaners is to put your hand over the end of the pipe to see if there's suction - if not, then the hose or some other passage is clogged, or there's an opening in the vacuum chamber section (door not fully closed or seated?) that's allowing air in where it shouldn't be getting in. If the hose isn't clogged, you'll feel suction and the hose may also contract, and the motor will speed up noticeably when you block the pipe with your hand.
