I've got a used one that has been sitting on the shelves for about 4 months. This lady who bought it new from the store about a year ago had surgery soon afterwards so she traded it in on a Royal Lexon S15 Canister. She now has all hardwoods and needs something lightweight.
The Perfect is not a horrible machine. The motor is much larger than the Diamond J and has more waterlift. The top of the machine literally looks like some sort of generic Electrolux (which it is). The switch is a pop-up switch like on the DJ-Ultralux and has rounded buttons instead of square. There is no automatic suction control like on the original Electrolux, thus, there is no pop-open when the bag is full. At almost 125in of waterlift, the machine still pulls well with an almost full bag. The used one I have, the power nozzle has been used once (in demo at the store) and the attachments have very little use.
