US Patent 7828963 Pool jet filter cleaner

The pool jet filter cleaner includes a tube in fluid connection between a t-handle and a multi-directional nozzle, a coupling, sleeve, base, and shut-off valve. The cleaner works by resting the filter upon the base, inserting the coupling sleeve about the top end of the filter, and inserting the sprayer into the hollow cylindrical center of the filter. The pressurized water passes through the t-handle, down the tube, and out the multi-directional nozzle thereby cleaning the filter from the inside out.
