A device or mechanism that cleans surfaces by removing moisture, dirt, or debris through wiping motion. Most commonly refers to windshield wipers on vehicles.
From Middle English 'wipen' meaning 'to clean by rubbing', ultimately from Proto-Germanic roots. The automotive sense developed in the early 20th century with the advent of motor vehicles.
The intermittent windshield wiper was invented by Robert Kearns in 1969, inspired by human blinking patterns—yet he spent decades in legal battles with auto manufacturers who stole his design! His story became the basis for the movie 'Flash of Genius,' highlighting how simple innovations can have complex consequences.
