waterfall / Sink(product)

After washing, there is always some dirt attached on the wall of the sink. The user must clean them by hand. It is really a disgusting and unpleasant thing for most people. So we have the concept of a sink cleaning system. We use the same principles of physics used by a toilet with an inner tube in the sink. Whenever the switch is open, water flushes from the inner tube along the sink and dirt will be removed along with water into the drain hole. It makes sink cleaning convenient and fast.
