Yes, you use your hand along with the water to clean! It sounds disgusting but actually feels super clean and hygienic once you are used to it.

Your hand will not smell afterwards and it is heavenly for the butt, feels so nice and clean. Also IME feces will lose some of their disgustingness, just because everything around it is so much cleaner now. I lived "western style" until 30 y/o and with a "bum gun" since two years, one of the best life improvements for me.
