This is one of the strangest top loaders I've ever seen. I've seen videos of it washing, it barely uses any water.
It's an interesting concept, but it's almost like a standard washplate washer.
What doesn't make any sense is why the paddles move forward then stop, then start moving forward again, rather than reverse... It's as if they were supposed to, but the engineers took that out of the motor and programming at the last minute...
It was an interesting concept at its time, but I've heard that parts for these things are difficult to come by and they're not cheap to fix.
The price is right, for someone who wants to collect those really weird machines, it might just be a labor of love!
