The fast short stroke, coupled with the load sensor agitator was a far better agitation than the long stroke, dragged the clothes to death and tear them apart agitation of the older machines
The sharp square fins of the power fin agitators would literally grab a shirt and yank it back-and-forth, straining the fibers, if you watch the short quick stroke of a direct drive machine or the Maytag orbital transmission or even a GE filter flow, which had a short fast stroke, you can see the superiority of turning over a load of clothing without damaging it as much.
Of course, all of this is ridiculous to argue about if you’re looking for the best type of washing machine, you’re gonna buy a tumbling front load type machine where the clothing is not damaged by the agitation.
