It's the robot bath from Roujin Z, but in real life

#12This should have multiple stepper sizes, and I will use the kids' settings regularly for my kids. Yes, I know the security concerns, and I will watch them, talk to them, or read a book while they are being washed.

#14How 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.
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.

#15Reminds 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.

#16> After five minutes of that, the machine would then fill the chamber with hot water for a three-minute ultrasonic bath. This was followed by a two-minute hot rinse cycle. Next, the chamber would drain and the user was blasted with warm air to dry off. They were additionally exposed to both infrared and ultraviolet light to kill germs. All in all, it was a 15-minute cycle.
It's apparently also a tanning booth.
15 minutes means it takes about 3 times longer than a shower, and it doesn't seem to do your hair.

#19As someone reading this while taking a shower, I'm questioning how this could be redesigned to work today. How are you supposed to use your phone if your head is sticking out?
How are you browsing HN in the shower?
Beware of the LED!

#20What 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 sounded modern.
