A washer system for cleaning surfaces such as automobile headlights directs jets or shots of liquid from a nozzle against the dirty surface. The nozzle is spring-biased toward the surface to be cleaned, and each shot moves the nozzle by jet reaction from the start position near the surface to a position farther away from the surface along a path such that the sprayed area progressively increases concentrically outwardly. The spring returns the nozzle to the start position between shots.
