ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to an automatic pool cleaner and, more specifically, to an accessory utilizing a plurality of different fastening means, that can connect a vacuum pole to an automatic pool cleaner so that a means for the user to selectively relocate and direct the pool cleaner to locations in a pool that were previously missed or not yet cleaned is provided. The attachment means consist of two mating members with one being attached to the end of a vacuum pole and the other fixedly attached to the surface of the automatic pool cleaner. The vacuum pole is an extending cylindrical pole having a throughbore wherein a pole attachment having a similar construction may be inserted and secured therein, being held structurally by a compression clip having securing pins that compress to then extend through securing holes, and frictionally by protrusions that align into depressions. Secured within, and extending outward from said pole attachment's throughbore is a universal ball joint connected within a connection member's cavity to provide a highly maneuverable surface wherein a selected fastener may be attached thereto. To connect the pole attachment's mating fastener to the automatic pool cleaner, a fastener attachment plate is provided. The fastener attachment plate has a bottom surface replicating the structure of the automatic pool cleaner so that it may be attached thereto by an adhesive or other bonding means, the top surface of the plate has attached thereto the mating fastener for the pole attachment. One such fastening means to connect the vacuum pole to the automatic pool filter being a piece of hook and loop material placed on the vacuum poles connection member with a piece of mating hook and loop material attached to the automatic pool filter wherein they may be joined with a hook and loop connection. Another means for fastening the said pole and automatic pool cleaner is a hook and ring, to form a connection whereby the hook fastener is impaled and grabbed through the center of the ring. Yet another means for connecting said pole and pool cleaner is by a mating threaded or bayonet style fastener that can be turned into its complimentary threaded or bayonet style aperture fastener. Furthermore suction may also be used as a fastening means between the said pole and automatic pool cleaner by having a suction cup applied to the vacuum poles connection member with the said connection plate having a planer smooth surface adhered or bonded to the automatic pool filter whereby the suction cup may be compressed onto the plates surface and attached thereto by suction.

An automatic swimming pool cleaner comprised of a car adapted to travel underwater along a random path on the pool vessel surface for dislodging debris therefrom. The car wheels are driven by a water powered turbine to propel the car in a forward direction, along the vessel surface. In order to prevent the car from being driven into a position, as for example against a vertical wall, from which it cannot emerge, a wheel geometry is employed which, upon contact, develops a horizontal force component parallel to the vertical wall, to thus enable the car to spin off. Alternatively, or in combination, a water flow produced reaction force can produce a torque to turn the car with respect to the engaged wheel to enable the car to spin off. The car is designed with a low center of gravity and a relatively buoyant top portion so as to produce a torque which maintains the car correct side up when on the pool bottom. Means are provided on the car for producing a water flow having force component perpendicular to the vessel surface to provide good traction between the car wheels and the vessel surface. Further, a water flow produced suction is created adjacent to the vessel surface for collecting debris into a basket carried by the car. In addition, one or more hoses is pulled by the car and whipped by water flow to sweep dirt from the vessel surface.
A vacuum powered automatic swimming pool sweep for cleaning the bottom of a swimming pool comprising a hollow housing supported by at least one pair of reversible wheels, a reversible impeller disposed within the hollow housing, the reversible impeller including an impeller housing having an impeller chamber formed therein, a reversible impeller member having at least one pair of opposing vanes coupled thereto operatively disposed within the impeller chamber and interconnected to the pair of reversible wheels, a fluid flow conduit including a first and second fluid flow path coupled between an external vacuum line and the impeller chamber, a directional control in communication with the fluid flow conduit to selectively direct water from the pool through the impeller chamber to impinge on the movable vanes coupled to the reversible impeller member to drive the pair of reversible wheels.
An underwater fitting is provided to allow a controlled leak of water into a suction line between a filter installation and an automatic pool cleaner. The fitting is T-shaped with the head of the T in the suction line and the leg of the T controlled by a tapered mandrel in an orifice which are adjustable to vary the effective orifice area. The mandrel is spring biased so that is can be pushed back in case of a complete stoppage of flow from the cleaner.
A cleaning system for a swimming pool which includes a mobile cleaning unit and/or stationary cleaning heads. Manual and automatic modes are included. The system is suitable for both gunnite and polymer liner pools, spas and the like. No energy is required other than that normally required for circulation of water through the conventional filtration apparatus.
An automatic swimming pool cleaner having a vibrator on the pool cleaner housing, main bristles projecting to main-bristle ends for supporting the device on a surface to be cleaned, the main bristles inclined such that vibration causes forward movement, and secondary bristles in fixed position projecting to secondary-bristle ends, the secondary bristles inclined in a different direction than the main bristles such that, upon contact with the surface to be cleaned, vibration causes a turning away from the forward direction.
An automatic swimming pool cleaner of the type driven by water flow, having a housing forming a chamber open at its lower side, pivotable attachment of a hose, and a handle pivotably and detachably secured to the housing, such that the pool cleaner can be used manually or automatically as desired. Various embodiments of the invention include vibratory bristle drive to provide forward motion, directional change, rotational scrubbing, and/or vibratory scrubbing action for dual-use (automatic or manual) and manual cleaning apparatus.
An improved pool cleaner hose assembly is provided for use in drawing water under a negative pressure from a manually operated pool cleaner device to a water filtration system for sw
