A windshield washer comprises a nozzle in which a liquid jet is formed and repetitively transversely swept before egressing from the nozzle body. The swept jet breaks up into liquid droplets which impinge upon a wide area of a windshield. In a preferred embodiment the nozzle is an oscillator, preferably a fluidic oscillator, in which the jet is swept oscillatorily between two extreme positions. In still another form of the invention discrete slugs of liquid are alternately issued in at least two directions from a common nozzle body.

The method of wetting a vehicle window as part of a window washer and wiper arrangement, said method comprising the steps of: pressurizing a quantity of wash liquid; forming a jet of the pressurized wash liquid; under the sole initiative of the pressure of said liquid, repetitively sweeping said jet in at least one dimension transverse to the flow direction of said jet in an oscillatory manner; and issuing the repetitively swept jet to cause it to break up into droplets which successively impinge upon said window in a generally fan-shaped pattern.
