Urinals with automatic drain

 

— this function, as the name suggests, drains water automatically, without user intervention. For this, special sensors are used — for example, those that respond to a person in front of a bowl or to an increase in the level of liquid in it. In addition to the obvious convenience, automatic draining provides additional hygiene: it eliminates the need for taps, valves and other devices for manually draining water, which would have to be touched again (which is not very hygienic, especially in public toilets). And the risk of forgetting about the flush is minimal. On the other hand, such urinals are not cheap.
