How many hundreds of gallons of water for a bath, then? I didn't see that in the story.
If it works anything like a modern dishwasher, it would use less water than a normal bath or shower.
It's the robot bath from Roujin Z, but in real life https://youtu.be/X5i0JU_NsZU?t=464
What does the ultrasound do?
On solid objects at least (like jewelry) it dislodges particles of grime / dirt. https://en.m.wikipedia.org/wiki/Ultrasonic_cleaning . No idea if this also works on soft tissue. Edit: the Wikipedia page above says "the ultrasonic action is relatively benign to living tissue but can cause discomfort and skin irritation.". So maybe it was just a gimmick. Ultrasound cleaning was fairly new at the time, so maybe it sound…
Truly remarkable creative thinking in a way that does not exist today. This was a year after humans landed on the Moon, and I can understand the inspiration that drove the 70s.
As for automatic washers: The idea isn’t totally gone - enclosed automated pet washers are around. (Despite being clearly terrifying for some pets.)
Earlier quoted context omitted.

But if it worked that way (using a small amount of water over and over to clean) would be gross and unsanitary in this case. One could filter it but that costs a lot of energy and changing a filter weekly on your shower pod would not be very green.

it's not unsanitary on your plates, why should it be on your skin?
But you don’t want to sanitise your skin, just get the dirt off, so I don’t see any real issues.
I can see why this didn't catch on, but on the other hand, I kinda want one.
Reminds me of my high school, where the gym showers were a car-wash arrangement, a corridor of sprays through which all the guys were herded nude after gym class.
If I would have to guess Soviet Russia?
