The main problem I saw with the Neppies was a result of their stupid suspension, two struts from below in the middle of the outer tub and four springs suspending it. With this arrangement, an unbalanced load could start the tub fishtailing where the ends would pivot side-to-side. You could look into the back and see the whole suspended mechanism swinging back and forth. If Maytag had done it right, they would have used 4 struts underneath, 2 in front and two in back, but it was a cost cutting thing. Of course, I was prejudiced against any front loader without a window, but the trouble it could have with the balancing was the third strike for it in my book. I think someone here figured out that you could not choose Max Extract with jeans because it only gave two tries at balancing while the regular spin gave more tries. So after jeans went through the regular spin, the machine could be set for Max Extract if you wanted that for jeans.
When Maytag came out with the Neptune, you would have thought that they had invented the horizontal axis washing machine; forget about Bendix or Westinghouse. Forget that Maytag even offered a tumble action horizontal axis wringer washer sometime in the 20s, I believe.
