I got really lucky a couple weeks ago and picked this off of the curb. This machine was in really bad condition and very dirty. I took the outer bag off and after vacuuming out all the debris from the inside of it, I threw it straight into my washing machine. As for the plastics sans the electronics and motor they also got vacuumed for all the major debris and then put it straight into The dishwasher. I inspected the brush roll it appears to be in very good condition I did put a new belt in and amazingly to me this machine being it is incredibly easy to service and take apart I expected the belt change to be a lot simpler than it was. However it wasn't a big deal and I got the new belt on just fine. The amount of suction this machine has is amazing, maybe it is just because it is light and completely made out of plastic but it sucks itself straight to my carpet and I can push it but there is some amount or resistance because of the suction.
