18. A venturi vacuum assembly for a pressure-driven pool cleaner connected to a pump, the venturi vacuum assembly comprising:
-
a suction mast with an open bottom end and an open top end; a lower manifold including a conical section tapering into a cylindrical section, the conical section positioned to receive debris from an underside of the pressure-driven pool cleaner, the cylindrical section coupled to the open bottom end of the suction mast; two first stage jet nozzles positioned in the conical section and directed upward and into the cylindrical section to induce a vacuum for suctioning the debris into the suction mast; and two second stage jet nozzles positioned along an inner circumference of the cylindrical section and directed upward and into the suction mast to induce a vacuum for suctioning the debris through the suction mast and out the open end. - View Dependent Claims (19, 20)
