Claim 0:
1. A diffuser for a pool cleaner tail sweep, the diffuser comprising:
a flow shaping nozzle having a first end comprising an inlet opening for receiving an inlet stream of pressurized water from the pool cleaner tail sweep, a second end comprising an outlet opening for discharging an outlet stream of pressurized water, a fluid conduit extending from the inlet opening to the outlet opening, and an obstruction in the path of the outlet stream of pressurized water, the obstruction configured to shape the outlet stream of pressurized water into an at least partially diverging flow pattern; and
a dissipating portion comprising a chamber into which the flow shaping nozzle discharges the at least partially diverging flow pattern, the chamber defining a central conduit extending through the entirety thereof, the dissipating portion comprising at least one dissipation element, and a fluid discharge opening;
wherein the diffuser operates in a first mode when submerged in a pool of water beneath a water surface, whereby the at least partially diverging flow pattern is directed through the fluid discharge opening of the dissipating portion in a concentrated stream in the first mode of operation when submerged in a pool of water beneath a water surface; and
wherein the diffuser operates in a second mode when positioned above the water surface, whereby the at least partially diverging flow pattern is directed to the at least one dissipation element of the dissipating portion to form a diffuse stream in the second mode of operation when positioned above the water surface.
