Electronic Toilet Seats

I sat the other day to do my business and was curious about the various controls on the toilet seat so I stayed in the stall quite a bit longer than anticipated. The green/white button closest to the seat flushes the toilet. The next button I tried produced a stream of air while another press caused a stream of water between the cheeks. These streams were controlled by the brown buttons closest to the rear wall allowing for an increase/decrease in water/air pressure. As I finished the paperwork and pressed the red button to turn off the stream of air and the power to the system, I got up to see where these streams were coming from. There seemed to be nothing there. I started pressing buttons. Still nothing. No power! I realized the seat was sensor activated by weight as shown by the red circle on the right front of the seat. Maintaining firm pressure with a couple of fingers, I was able to press the green/white button again to turn on the power. If I released the pressure with my right hand, the power would go off. I again started pressing buttons not remembering which ones performed which duties in order to see where the stream of water came from. The next one I pressed rapidly extracted a thin rigid tube from the rear and squirted a stream of water almost to the door. With my right hand holding the pressure down on the red button and my left hand pressing a button with instructions written in Korean, I happened to be standing in the middle of the stream as I got hit from my chest and below. Immediately afterwards, I washed my hands, took a shower and did laundry. The other toilet is self explanatory. I have yet to try this one as the ones with a seat, I feel are much more comfortable.
