So I saw a commercial for a "touchless toilet". It appears to be designed for homes.
So, you sit on the thing, take a crap into it and wipe your butt afterward, but the idea of touching the flush handle skeeves you out?
Well, okay, then.
Are you meant to hover over it?
You flush by holding your hand over the tank (back).
Maybe it's for people who are really messy in the toity? (Gross)
Possible. I think, more likely, someone just wanted to design a high-tech throne and thought "there are germs on the handle, gross" and didn't put a lot of thought into the activities that occur before flushing. On the whole, a pretty dumb invention.
Nice scenario: "Honey. Ignore the floater in the toilet. I have to run down to the store and buy some batteries so I can flush it."
(By the way, it is possible to get a toilet to flush with a broken handle. Growing up poor, you learn to improvise.)
