Well, the Bendix was the first automatic washer. It came out in 1937 and was a hard mount. As far as I know, there were two designs: the "Standard" which is pictured above, and the "Deluxe" which had a squared off cabinet surrounding the tub and base. Both were mechanically identical. This hard mount design continued until about 1950. Then Bendix came out with a soft mount washer, and then a combo washer/dryer. There were minor changes in the hard mount washers during their 13 year run, such as changing the fill flume location, but basically it was the same product. It was very popular despite the hard mount requirement, because it was the first fully automatic home laundry system.
