The automatically cleanable bathroom already exists. I have used them years ago in cheap hotels. After taking a shower, it locked the door once you exit and it rinses the whole room with some detergent and water for 30 seconds.

I just had a mental image of it bugging out and flooding the room with detergent with an occupant still inside...
