A car's wiper system is designed to keep the windscreen (windshield) clear of rain. It consists of a synthetic rubber blade, held on a resilient arm which is pivoted at one end. The arm oscillates back and forth such that the rubber blade sweeps across the windscreen and disperses the rainwater.

Its function is aided by including jets which can spray water containing a detergent on to the screen.
