I can’t even get the main water valve to close.

I also tried it once with the focused setting on a shower head and it was just a mess. It goes everywhere, but doesn’t get rid of it properly. And in the end you end up with a dirty wet ass that you still have to wipe. I also feel that the toilet bowl does not offer enough space if you have one with a shelf, add a big dump to that and you’d have to poke it with the bidet.
