Behind is for anyone's rear end. Bidet is for women. Not sure I want to explain more fully ;-)

It.... takes some experience... But definitely worth it in my experience :-)

Yeah, I figured that's the theory, but in practice I've found no consistent aiming for either function. Also, most washlets with both also have an independent forward/backward function.

Besides all that, is there some targeting system going on down there? Machine vision? Lidar?

None that I know of. A combination of adjusting yourself and using the forward back buttons usually works. There are also some with pulsating streams for extra scrubbing power.

> Machine vision?

God please no. Don't give people ideas, lest we want to have a cloud-connected startup doing just that...

Simpsons did it? https://youtu.be/BPLrNWAsBWU?t=18

There's also that Adult Swim infomercial... https://www.youtube.com/watch?v=DJklHwoYgBQ

It's going to happen sooner or later. I'm pretty sure the $8000 models employ some kind of computer vision to adjust the sprayer to the correct "human output interface".

A cloud toilet that examines your feces and urine probably isn't far off (and is probably already in the works).

So I guess that beyond Cloud-to-Butt, we'll have a Butt-to-Cloud extension...

The rise of self-aware bidets will end poorly...

Just wiggle your behind around until you get the right spot
