Bendix Economat
These were interesting machines. You have to realize that the automatic Bendix machines of that era were front load and had no suspension system. They had to be bolted to the floor or they would "walk" when they started spinning -- perhaps "dance" is a better word.
The economat could be set down, plugged in, and off we go. There was no vibration or "walking."
Yes, there was an agitator very similar to ones used in the Maytags of that era, but it had holes in it. It had a nice long stroke like the Maytag.
The tub was rubber. There was a round kind of dome type thing on the lid that, when closed, created a seal. When the machine started the drain cycle, it would keep pumping and create a vacuum inside the tub. The suction would pull the sides of the rubber tub in toward the agitator, and the clothes would be squeezed up against the agitator.
The problem for those of us enthusiasts in this forum is that there is no way to watch what's going on during the extraction cycle.
I have used two different models of this machine, one of which never worked well with the extraction. The other one did a fine job. When it was done, the clothes were so tightly packed against the agitator they would sometimes be difficult to take out for line drying.
There are a few of these machines still around. I think it would be great if you could find one and use it.
Good luck.
