Abstract
A nozzle for a fluid vacuum cleaning system for simultaneously applying a cleaning fluid and a vacuum force to a surface is provided. The nozzle includes a hollow, rigid wand attached to a suction chamber and a cleaning fluid dispenser head. The suction chamber consists of a front plate and a rear plate which are connected together by a top plate and a pair of opposing side plates. The suction chamber has an open free end in the shape of a narrow slit and further includes at least one aperture positioned on the rear plate. As the cleaning fluid dispenser head sprays a fluid on a surface, the suction chamber removes moisture and dirt from the material being cleaned. The apertures on the rear plate serve to draw in any excess liquid that has accumulated on the surface.
