Abstract
An automatic cleaner device for automotive headlamps and the like which uses cleaning solution sparingly and hence which require only a small cleaning solution reservoir. For each cleaning operation, the fluid is jetted in two spurts. The first spurt penetrates and dissolves the dirty film on the lens, and the second spurt washes away the dissolved film.
