A wiper system for use with a windshield includes a track guide, a wiper assembly, a drive mechanism and a wipe mechanism. The wiper assembly has a wiper arm attached at a first end thereof to a rotor rotatably disposed on a wiper carrier, wherein the wiper carrier is engaged with the track guide and is configured for translation therealong. The drive mechanism is connected with the wiper carrier and is configured for positioning the wiper carrier along the track guide. The wipe mechanism is connected with at least one of the rotor and the wiper carrier and is configured to cause the rotor to rotate, thereby causing the wiper arm to produce a wiping motion.
