Automatic swimming pool cleaning systems are disclosed. The systems include an automatic swimming pool cleaner incorporating one or more curved wipers protruding from its lower surface. The wipers and flat bottom of the cleaner induce a vortex as fluid flows to its central inlet, entraining debris in the flow. A fluted throat surrounding the inlet additionally assists the interior of the base of the cleaner in retaining debris when opened for cleaning, additionally providing an improved flow path for enhanced debris pick-up. Also disclosed is a valve useful for controlling and indicating the rate of fluid flow to a cleaner. Included within the valve is a plunger attached to a spring, with the spring force opposing fluid flow through the valve. Flow sufficient to overcome the spring force compresses the spring, however, thereby moving the plunger within the tube and providing a dynamic indication of the rate of fluid flow. A diffuser and fluid release ports permit the valve to be adjusted to achieve a desired flow rate.
Disclosed are a plurality of different fasteners that can connect a vacuum pole 14 to an automatic pool cleaner 12 so that the user can selectively relocate and direct the pool cleaner 12 to locations in a pool 18 that were previously missed or not yet cleaned. The vacuum pole 14 is an extending cylindrical pole having a throughbore 34 wherein a pole attachment 26 having a similar construction may be inserted and secured, being held structurally by a compression clip 44 having securing pins 32 that compress to then extend through securing holes 34, and frictionally by protrusions 38 that align into depressions 40. Secured within, and extending outward from the pole attachments is a universal ball joint 26 connected within a connection member 42 cavity 43 to provide a highly maneuverable surface wherein a selected fastener may be attached. To connect the pole attachment's mating fastener to the automatic pool cleaner, a fastener attachment plate 56 is provided. The fastener attachment plate 56 has a bottom surface replicating the structure of the automatic pool cleaner 12 so that it may be attached by an adhesive 28. The top surface of the plate 56 has the mating fastener for the pole attachment 24.

This invention provides a manual, self contained, portable, low voltage electric pool cleaner which draws its power from a surface mounted rechargeable battery. The invention uses pressurized water from a unique pump recirculating system to produce a powerful suction effect necessary for debris removal by an integral filter. All components are submersible except for the power source, which is either handle mounted, or attached to a belt harness worn by the operator. This arrangement precludes the need for external wiring and hoses, thus making the invention a truly portable pool cleaner.
Systems and apparatus for cleaning swimming pools or other vessels are disclosed. Exemplary systems may include an automatic swimming pool cleaner adapted not only to filter debris from water mechanically, but to dispense water sanitizing chemicals as well. Fluid drawn into the cleaner in operation contacts or otherwise passes through media containing the chemicals, purifying the fluid at least partially within the cleaner itself.
A pool cleaning apparatus is provided that employs a pump and a filtering device. An engine or motor drives the pump. The pump draws water and debris into the pool cleaning apparatus through a wand. The pump moves the water through the filtering device to remove debris. The filtering device comprises a vessel having a sealable lid. The vessel contains a tube for transporting water and debris into the vessel, a leaf trap for catching debris, a primary filter of polyester fiber, and a positive stop having a gasket. The primary filter sits on the gasket, with the leaf trap resting above the primary filter. Both the leaf trap and the primary filter have a hole through which the tube extends, and handles. The primary filter houses a filtration element which is washable and disposable. The pool cleaning apparatus may be mounted onto a cart, or be permanently installed.
