The present water conserving and cleaning apparatus' major components include an essentially straight handle of several feet in length, with a hand grip in the vicinity of a distal end and a water low control lever operably secured to a straight fixture removably secured to the hand grip. The handle is secured on the proximate end to a horizontal member in an inverted "T" configuration. A specific angle at which the handle is secured to the horizontal member is preferred for maximum comfort value for adults. The horizontal member includes a winged jet manifold fixably secured to the proximate end of the handle. The manifold includes a flow director which directs an air and water jet stream onto a surface to be cleaned. A rear wing, integral to the jet manifold, includes a two level cantilevered porch with specifically designed angles and heights to provide optimum air flow and a Venturi effect under the cleaning apparatus. A minimum of water is required when combined with an air stream to provide maximum pressure at a specific target angle to the surface to be cleaned. In addition, a cylindrical horizontal length of pipe is integrally manufactured into the manifold. Also, a plurality of spray nozzles are secured underneath the horizontal length of the cylinder at generally equally spaced intervals. Finally, on a rear side of the manifold is movably secured a plurality of wheels. Several embodiments demonstrate design flexibility and adaptability to a variety of surface cleaning uses.

What is claimed is: 1. A cleaning device, comprising: an elongated handle; an elongated hollow jet manifold defining a transverse dimension generally perpendicular to the handle, the jet manifold being engaged with a lower end portion of the handle without intervening structure between the manifold
What is claimed is: 1. A cleaning device, comprising: an elongated handle; an elongated hollow jet manifold defining a transverse dimension generally perpendicular to the handle, the jet manifold being engaged with a lower end portion of the handle without intervening structure between the manifold and handle; plural nozzles spaced along the jet manifold for spraying water directed into the jet manifold onto a surface; a flat forward wing extending from the jet manifold above and forwardly of the nozzles such that water from the nozzles can spray beyond the forward wing during operation, the forward wing being elongated in the transverse dimension; a flat rear wing elongated in the transverse dimension and having a front transverse edge engaged with the jet manifold, the rear wing extending rearwardly of the nozzles and terminating in a rear transverse edge, the forward wing being slanted with respect to the rear wing being substantially parallel to the ground when the device is being used to spray the ground, an air flow space being defined between the rear transverse edge and a surface beneath the device when the device is rollably engaged with she surface to clean the surface; and at least one wheel on the device to rollably engage the surface, wherein the wings cooperate to establish a Venturi effect when water is sprayed onto the surface through the nozzles, wherein air outside the jet manifold below the wings is entrained into water being sprayed from the nozzles onto the surface, thereby facilitating cleaning the surface with both the water and the air. 2. The device of claim 1, wherein the forward wing extends down from the horizontal in a longitudinal dimension that is perpendicular to the transverse dimension when the device is oriented to clean a surface beneath the device. 3. The device of claim 1, wherein the handle is hollow and defines a fluid passageway communicating with the jet manifold, the handle including a water connector connectable to a source of water for directing water through the handle, jet manifold, and nozzles. 4. The device of claim 3, further comprising a valve on the handle and manipulable to block the fluid passageway. 5. The device of claim 1, wherein water flow onto the surface is no more than three gallons per minute at a water source pressure of up to eighty pounds per square inch. 6. The device of claim 3, comprising a filter disposed in the fluid passageway of the handle. 7. The device of claim 6, wherein said filter is frusto-conical shaped. 8. A cleaning device, comprising: an elongated handle; an elongated hollow jet manifold generally perpendicular to the handle, the jet manifold being fixedly engaged with a lower end portion of the handle; plural nozzles on the jet manifold for spraying water directed into the jet manifold onto a surface; a flat transversely elongated forward wing extending from the jet manifold forwardly of the nozzles; a transversely elongated unitary rear wing extending from the jet manifold rearwardly of the nozzles and terminating in a rear transverse edge without further structure rearwardly of the rear transverse edge that is closer to the ground during operation than the rear wing, an air flow space being defined between the rear transverse edge and a surface beneath the device when the device is rollably engaged with the surface to clean the surface; at least one wheel engaged with the device to rollably engage the surface, wherein the wings cooperate with each other such that air outside the jet manifold between the wings and a surface being cleaned and air from behind the rear wing is entrained into water being sprayed from the nozzles onto the surface, thereby facilitating cleaning the surface with both the water and the air. 9. The device of claim 8, wherein the forward wing extends down from the horizontal in a longitudinal dimension when the device is oriented to clean a surface beneath the device. 10. The device of claim 8, wherein the handle is hollow and defines a fluid passageway communicating with the jet manifold, the handle including a water connector connectable to a source of water for directing water through the handle, jet manifold, and nozzles. 11.
