That is actually very smart. It’s amazing and quite sad how much people these days completely take washers for granted, especially since they were designed by someone much smarter than all of us. And not to mention how impressive the engineering was that went into them. Maytag’s nylon ball hinges, so simple yet such a brilliant “why didn’t I think of that” idea. Maytag’s orbital transmission, a reliable, simple, and compact transmission design that was genius. The resulting agitation may only have a short 90 degree stroke, but it was fast and it got the job done. Whirlpool’s direct drive, honestly probably the best drivetrain systems that eliminated the problems from having a belt and was extremely easy to work on if something actually broke. And finally, the agitator itself. You don’t just put fins on a stick and call it a done deal. You use fluid dynamics and general physics to design an agitator that has strong rollover, good scrubbing ability on all water levels, creates strong water currents, is gentle on clothes, and is still capable of performing well when overloaded. Sure, a lot of this is also dependent of the stroke size and speed determined by the transmission and motor, but the best agitators take full advantage of whatever drivetrain they are paired with.
