    Abstract: A recessed incrementally rotating nozzle assembly is located in a wall or bottom surface of a swimming pool in fluid communication through a conduit with a source of water under pressure from a valve, which valve periodically releases water into the conduit. Each time water flows, a nozzle housing is raised to eject a stream of water. As the nozzle housing rises, it is incrementally rotated by a pin engaging a saw tooth member of a cam ring. Upon cessation of flow, the nozzle housing is retracted and during retraction the nozzle housing is further incrementally rotated by the pin engaging another saw tooth member of the cam ring. After a predetermined degree of angular rotation, a cam reverser slidably reorients protrusions guiding the pin into and out of the saw tooth members to cause the pin to be guided by the opposite side of the saw tooth members and thereby cause reversal of the direction of rotation of the nozzle housing.

  • Patent number: 7504025
    Abstract: A floating self-propelled cleaning device (10) for water surfaces, in particular swimming pools, comprises a central floating body (11) and two side floating elements (12) to it connected at opposite sides by two arms (14) to which two net-shaped collecting containers (13) are fastened. The net-shaped containers (13) have openings (17) that allow the inlet of impurities, but prevent the outlet thereof during possible stops or under the action of waves that can occur during the travel on the water surface. The floating device (10) is driven by propelling means (20) and (30) that substantially cause the side floating elements (12) to rotate about an instantaneous centre of rotation located approximately at the central body (11). The rotation of the side floating elements (12) is associated to a shifting movement caused by at least a distribution element (15) movable with respect to the floating body (10).

  • Patent number: 7501056
    Abstract: An automatic pool cleaner configured to be powered by a supplied positive pressure water flow including an improved propulsion subsystem for propelling the cleaner body through a swimming pool along a substantially random travel path. The subsystem includes a hydraulic valve actuator configured to use water pressure to switch a valve element mounted for reciprocal linear movement from a default state (e.g., redirect travel state) to an active state (e.g., forward travel state) and to then restore the valve element to the default state. The water pressure for controlling the actuator is selectively supplied by a direction controller which responds to regular periodic occurrences and/or irregularly occurring events such as the interruption of cleaner body motion.

  • Patent number: 7441284
    Abstract: A device for moving the hose of an automatic pool cleaner in and out of a swimming pool using water power. The device includes a rotatable hose reel disposed within a tank spaced from the pool. In one embodiment, the tank communicates with the pool through an under-the-deck tunnel. In another, the tunnel extends from the tank and over the deck of the pool, for discharge into the pool. The hose reel is connected to a rotatable water wheel having vertically-oriented blades disposed around its circumference. To move the hose from the storage position into the pool, a stream of water from a blow out jet nozzle flushes the hose into the pool and rotates the hose reel in a first direction, causing the hose to unwind and travel into the pool.

  • Patent number: 7296308
    Abstract: The invention comprises, in one form thereof, a water circulator that connects to the pressurized water inlet in a swimming pool. Water from the pool is pumped through the pool's filter system and into the water circulator through the pool inlet. The water circulator includes a jet tube that is vertically oriented and proximate to the pool's side wall. The pressurized water exits the jet tube through several nozzles in the jet tube. The nozzles direct the pressurized water along the side wall to thereby direct debris toward the pool outlet. The pool outlet carries the debris and water to the pool's filter system. The nozzles direct the water away from the pool outlet so that the water current travels along the majority of the side wall before reaching the pool outlet. Thus, more debris may be picked up in the current and slower moving water passes the pool outlet. The jet tube further includes one or more outlets proximate to the pool floor.
