Hi folks, I have the identical model, although not hooked up anymore. It was OK, but didnt seem to clean that well. Mine used to squeak like crazy until I put on a new belt and lubed it. It was fairly quiet after that. I saw a used KitchenAid Superba 20 in a house sale last year, mint condition. Pulled the Maytag out that day, and haven't had a dirty dish since!
