Abstract: A four-wheel pool cleaner (20) motivated by water flow to move along a pool surface, and having: a body (24); the four wheels rotatably mounted thereon and including two sets of two wheels (22) each, one wheel of each set on each side; a drive mechanism (36) in position to be moved by water flow and having a rotatable drive member (76); a drive train extending to the first wheel set (22a, b) and to the second wheel set (22c, d), to drive all four wheels. Preferred embodiments include: wheel-to-wheel drive links (88) along the side; a turbine (36) as drive mechanism; a pair of spaced wheelgears (32, 34), preferably integrally formed with the wheel, facilitating drive linkages and steering; a pair of end-to-end drive shafts (80, 82) joined by a coupler (84c), one shaft end (80a) being a ball joint allowing fore-and-aft movement of a drive-shaft distal end; a spring (102) and cam (100) for alternately moving that distal end between a driving position engaging one of the spaced wheelgears (32), and a steering position engaging the other of the spaced wheelgears (34); wheel treads (108) with radial fingers (110), some (110a-c) of longer length; and a segmented articulated skirt (56) to help enclose a plenum beneath the pool cleaner.

Abstract: An automatic vacuum-relief apparatus for liquid suction systems includes a vessel defining a chamber filled with liquid in communication with a liquid flow line, a rotary shaft extending through the chamber to support a valve device adjacent to the liquid flow line and to move the valve device to open a relief-air flow channel to relieve increased suction caused by inlet blockage, and a piston on the rotary shaft responsive to suction increases within the liquid flow line and chamber to actuate shaft rotation. The valve device, chamber and relief-air flow channel are configured and arranged to cause a spurt of liquid from the chamber into the inlet while the valve device is moving from its isolating position toward its opening position upon inlet blockage, whereby the spurt of liquid pushes the blockage away from the inlet and the relief air reduces the suction. The valve includes a liquid-flow barrier secured with respect to the liquid flow line such that the barrier is in an open position allowing flow of liquid from the inlet to the outlet during normal operation and in a closed position isolating the inlet from the outlet in response to suction increases upon inlet blockage.

Abstract: A swimming pool cleaner of the type movable along an underwater pool surface to clean debris therefrom. The pool cleaner includes a body having a debris inlet and a debris outlet. A rigid debris-collection canister is secured to the body over the debris outlet to collect debris in the rigid canister and pass filtered water either back into the pool or to a remote suction system such that the collected debris remain at the pool-cleaner body for easy maintenance while allowing free flow of water through the rigid canister. The rigid canister is shaped to minimize obstructions to the pool cleaner movement in the pool by providing improved buoyancy and limiting entrapment of the cleaner by underwater pool structures. The cleaner body is adapted for securement of either a water-suction hose connected to a remote suction system or a venturi-line structure connected to a water-flow line fed by a remote pump such that the pool cleaner is interchangeably usable as a suction cleaner and as a pressure cleaner.

Abstract: A swimming pool cleaner interchangeably usable as a suction cleaner and as a pressure cleaner. The cleaner is of the type movable along an underwater pool surface to clean debris therefrom, the pool cleaner including a body having a debris inlet and a debris outlet. The body is adapted at the debris outlet for securement of either a water-suction hose connected to a remote suction system or a debris-collection device entrapping debris and passing water therethrough back into the pool. A venturi-line structure is secured with respect to the body. The venturi-line structure includes a venturi-line inlet adapted for connection of a water-flow line fed by a remote pump and a venturi jet located at the debris inlet to cause accelerated flow substantially thereacross and into the body when the cleaner is used as a pressure cleaner. The body includes a debris-inlet adjuster configured to reduce the debris inlet to adapt the cleaner for use as a suction cleaner.

Abstract: An debris-capturing apparatus having a fluid-pervious wall, an attachment portion attachable to the outflow port of a pressure-cleaner device, and a collapsible inflow tube that is substantially opened and made erect by the inflow of fluid but otherwise axially collapsed and thereby closed so as to block reverse flow of debris through the outflow port. The erected inflow tube preferably has cross-sectional flow areas along its entire length approximating the cross-sectional flow area of the outflow port. The debris-capturing apparatus is preferably integrally formed such that the inflow tube is a turned-in extension of the attachment portion.
