I found this on Offerup for free. The person said that they removed the bottom plate to clear hair off the brush roll and it didn't work right after the reassembled it. Because it wasn't working, her boyfriend bought her a new machine. All she did was clamp the bottom plate on the belt. It has a burnt spot on the belt, but it's fine other than that. The belt isn't as tight as it could be, though. Despite that, now that I fully disassembled and cleaned this unit, I am going to sell it. I don't collect Bissell cleaners and I have no desire to keep this one. I have been making a decent profit by restoring and selling these Bissell cleaners.
This Bissell was made by Suzhou Eup. They have made cleaners for many other companies such as Hoover and Dirt Devil. Like all of these Bissell bagless units, it doesn't separate fine dirt well. Its filters need to be cleaned very regularly.
