Abstract:

A spray-type device effects cleaning and sweeping as for walks, driveways, patios, lawns and the like by attachment to a pressurized source such as a garden hose. A T-shaped configuration is employed with an elongated hollow tubular handle for attachment to the source at one end and with a series of members attached in perpendicular relation to the other end of the handle. One of the lower members has a hollow interior in communication with the handle interior and having a series of nozzles attached thereto along one side so as to form a narrow fan-like sheet of spray directed downwardly and forwardly of the nozzle mounting members. The lower members are rigidly interconnected in a solid structural frame with roller wheels or casters attached at opposite ends. The nozzles can include a horizontal slot arrangement which is aligned for producing an overlapping sheet of sprays and the wheel mounts are preferably in an offset relation to the spray line to facilitate control of the angle of impact for the spray on the surface to be cleaned. Supplementary materials can be added to the flow through attachment of an injector-type apparatus at the input handle.
