Abstract
An apparatus for breaking up, dissolving and flushing away animal excrement left on the ground or lawn includes a hollow cylindrical handle section coupleable to a garden hose at its upper end, and terminating in a hollow, frusto-conically shaped spray head at the lower end of the handle section. The spray head includes a hollow exterior shell section, and an orifice plate transversely positioned within the hollow interior space of the shell sections, the orifice plate having plurality of regularly spaced orifices whose entrance openings communicate with pressurized water introduced into the upper end of the shell section by the handle section, and whose lower exit openings produce streams of water at various angles adapted to efficiently break up a pile of animal excrement. Spikes protruding perpendicularly downwards from the lower surface of the plate and extending below the lower annular wall surface of the spray head shell provide a mechanical breaking action when vertically and/or rotationally impacted against a pile of animal excrement, to assist the hydrodynamic ablation action of the water jets.
