I don’t know about you, but after I’m done doing what nature intended (not the fun thing, but the other, disgusting thing), I want all involved items (parts of my body and appliances) completely clean. I’m a bit anal about it (har har).

So, why don’t toilets take care of this for me? How hard can it be: you look, if anything’s floating, or otherwise disturbing the water’s clarity, just keep on flushing. If the toilet did this for me, it’d be oh so much quicker to continue with my day.

I imagine a visual sensor and some very simple pattern recognition ought to do the business.

Since saving water is an important environmental, I think there should be a regular flush setting. Or maybe three settings:
“number one only” (small flush), “nice number two” (regular flush), and “Mommy, I’m scared of the nasty thing, make it go bye-bye”.

I live to share ideas like these.
