Looks like I got the evil twin to yours, mine was free and in perfect mechanical condition aside from needing a new belt (even clean inside and the brush roll is like new!) But must have been stored where some type of cleaning chemicals were stored (came from a daycare/preschool with 4 other machines) and had been spilled on it. I washed the parts from all the machines with no cleaners, whatever had been spilled on them was soapy and smelled nice. The soap/chemical (I'm assuming either hand soap or floor cleaner) pitted the aluminum pretty badly in a few places and took the shine off completely. I spent hours trying to polish it up and finally just gave up. It works great, and I really can't complain for free (even had some attachments and the shampooer). It looks OK, but I doubt it'll ever look new again. I need to order some bags (it had a new one installed but that had been saturated in whatever as well, I filled it and don't have any extras) and wash the outer bag.
