A scrubber assembly includes a scrubber support structure, a scrubber element and a vibrating motor. The scrubber support structure is configured to attach to a windshield wiper. The scrubber element is movably attached to the scrubber support structure and extends between a first end and a spaced apart second end along a central longitudinal axis. The motor is mounted to the scrubber element so as to cause the scrubber element to vibrate when the vibrating motor is activated.
