My Bissell swallowed water with lots of dirt. He was covered with unpleasant things. I was planning on throwing it away after buying a new Bissell but decided to take the time to clean it for use in my second home. The original brushes appear to have had corrosion on the bushings/bearings. The belt slipped off the engine and burned through the belt. This new brush set spins freely and works great! The vacuum cleaner lives again! 😃🙂
