Abstract
Multiple side-by-side vacuum nozzles are reciprocated along paths of travel parallel to the preferred path of travel of carpet cleaning apparatus. The vacuum nozzles are propelled through a drive mechanism which moves each vacuum nozzle out of phase with the movement of every other nozzle. Cleaning fluid discharge members associated and movable with each vacuum nozzle direct cleaning fluid onto the carpet adjacent their respective vacuum nozzles.
