How does an auto flush work on a urinal cistern?

An auto flush system on a urinal cistern operates using sensors or timers to detect when the urinal is used. When a user approaches, a motion sensor activates the flush mechanism to clean the urinal after use. In timer-based systems, the flush occurs at set intervals, regardless of usage. This helps maintain hygiene and reduces water waste by ensuring that the urinal is only flushed when necessary.
