Okay imagine this. You finish taking a shit. And then there's a hole in the wall that you stick your ass in. Then your ass sealing the hole creates a vaccum where it can then flood the hole by violently shooting warm soapy water at your ass. It does this for 3 cycles with new recycled soapy water each time. Then it switches to the dryer mode and completely dries your behind.

Engineering details, what's the seal pressure reachable before rectal prolapse?

Yup.

That reminds me. This would never work since everyone has different sized asses.
