I don’t know why I found this product so assuming but it’s clever in it’s simplicity. As evidenced by the photo, there are two flush levels on this thing. The lower volume flush, shown as one green water drop, is meant for “light” flushes while the higher volume flush, shown with three water drops, is meant for “heavy” flushes.
Seeing how this is an automatic flushometer and no one touches those buttons, you have to ask the obvious question: How does it know if it needs to flush light or heavy? Well according to Sloan, once you are in front of the infrared sensor, a timer starts. If you are there for 65 seconds or less, it uses the “light” flush and if you are there for… err…. longer, it uses the “heavy” flush.
I could just imagine a Sloan engineer spending weeks timing people going to the bathroom to find the optimal time to differentiate light from heavy use.
Sadly, after reviewing the specs, the lower volume flush is 1.1 gallon per flush (gpf) and the higher volume flush is 1.6gpf. This isn’t Sloan’s fault - plumbing codes and congress set those values.
Still so amusing to me, I’m such a child. Maybe I should get those pajamas.

That is awesome…seriously, great engineering is always so simple!
