Did y'all notice the see-thru inner lid that closed before the outer lid? I'll bet it is to keep all of the splashing contained since there is a gap between the tub and the top of the machine.
I wonder how badly it tangles?
You can believe this or not, but when I was 5 or 6, I would watch the Bendix washers with the slide lever to open the door at the dry cleaners/laundry where we used to take cleaning. I would look in the tub of an empty machine and imagine a top loading vertical axis washer with a tub like the Bendix with 4 vanes, but in the center where that big bearing bump is, I imagined a stationary agitator. The tub whirled back and forth, full of water, carrying the clothes while the fixed agitator kept them from balling up and gave something for the laundry to dash against to force water through the clothes. I did not imagine anything more than spray rinses whle spinning and the agitated deep rinse, but laundry technology is catching up with my imagination 50 years ago. It would be neat if the little Haier I have had some big vanes in the tub wall.
