Abstract

A pool cleaning apparatus characterized by a long, hollow main body coupled to a pressurized swimming pool inlet and supporting a pair of cleaning hoses, a pressure relief valve, and an adjustable nozzle for producing a surface current. A primary cleaning hose sweeps the side and bottom surfaces of the pool, and a secondary cleaning hose follows up after the primary cleaning hose. The adjustable nozzle is used to direct a jet of water towards the surface of the water contained by the pool to create surface currents which urge floating debris towards the swimming pool's skimmers. The pressure relief valve controls the strength and vigor of the cleaning action of the apparatus.

Dependent claims

A pool cleaning apparatus for attachment to a pressurized inlet of a swimming pool, the apparatus comprising:

(a) a main body portion provided with a chamber;
(b) first means coupling said main body portion to said inlet such that pressurized water may flow from said inlet into said chamber;
(c) a pressure relief valve coupled to said main body portion for selectively venting said pressurized water within said chamber;
(d) an elongated, flexible primary cleaning hose having a first end coupled to said main body portion and opening on said chamber, whereby pressurized water from said chamber may flow out a second end of said hose;
(e) a nozzle submerged below the surface of the water contained by said swimming pool to direct a flow of water towards said water surface;
and
(f) second means coupling said nozzle to said main body such that pressurized water from said chamber may flow out of said nozzle, wherein said second means is adjustable to permit the angle and direction of the flow of water from said nozzle to be varied.
