The only way that makes sense would be if they were actually sonic bidets. They could have reverse replicator toilets though, that dematerialize the bio waste.
I can’t help what happened in the show. Jankom used the bathroom and said he broke the sonic toilet. There was a flushing sound as he came out. Maybe it’s a sort of holdover thing? Like it makes that sound to let you know that the waste is being removed, but it’s a recording?
Like the fake engine sounds on some EVs.
You can break them if you don’t know how to use the three shells.
Half flush, full flush, bidet. It’s jot complicated.
I’ve had a lot of bidets. One button is not enough. Hot? Cold? High pressure? Low pressure? Power cleanse? Front? Back? And that’s just the paper. Water options are worse.
We have sonic shower thoughts. Now we have sonic toilet epiphanies!? Awesome!
