By spotless toilet with a robotic bidet, I suppose you mean the washlet that's usually covered in fecal matter. Trust me, you don't wanna accidentally look under there.

Anyway, you're a madman if you're using a public washlet! Also have you ever seen a park toilet here. I shudder just thinking about it. Zero privacy urinals open to the world, or a squat toilet that the last 100 people didn't so much as aim into, but rather aim at. A layer of urine nicely coating the floor is typically your welcome as well.

The only "spotless" toilets I have seen have been in hotels and nice department stores, and sometimes the disabled toilets in some stations.
