Query: Cleans great IF you can get it to work

I bought the Bissell 7920 ProHeat ProTech Carpet Cleaner two weeks ago, got a very quick delivery from Amazon.com, used the thing in one room and it quit working. No water is being pumped out of the "tank-in-tank" bladder. I was desperate to clean my carpets (5 animals) so I sprinkled water and solution from a bottle and used the machine for suction. Two hundred bucks toclean one room in my house. Does a great job when it works.
