  • Patent number: 10584507
    Abstract: A swimming pool cleaner is driven along a submerged surface by water and debris flowing past a turbine positioned between an inlet and outlet of the cleaner. Retractable elements carried proximate the inlet form a plenum for water to enhance adherence of the pool cleaner to the submerged pool surface being cleaner. A drive train independently drives each of two wheels for maneuvering the pool cleaner in forward and reverse directions along the submerged surface. A hose connector operable with an outlet port is angled toward the forward direction of movement of the pool cleaner such that a suction hose will be placed slightly ahead of the pool cleaner when climbing a side wall surface to provide a weight for keeping the cleaner below the water surface and thus prevent an undesirable sucking of air at the inlet.

  • Patent number: 10224839
    Abstract: A smart power switch for a swimming pool vacuum having a battery powered motor for driving a propeller within a vacuum head to create thrust and suction; the power switch including a microprocessor combined with two integrated motor-driver integrated circuits for driving the motor at different speeds and for detecting and clearing motor jams. Red, green and blue LED indicators notify the user of the state of the motor and motor driver. The microprocessor detects spikes in motor current to determine a motor jam and operates the motor driver to control the motor, including stopping and reversing the motor, to clear an obstruction in the vacuum head.

  • Patent number: 10221584
    Abstract: An automated swimming pool cleaner has a housing having an inlet formed on a bottom surface thereof. A drive mechanism is located within the housing. A first rolling mechanism is coupled to a bottom section of the housing. A second rolling mechanism is coupled to the bottom section of the housing. A third rolling mechanism is coupled to the bottom section of the housing between the first rolling mechanism and the second rolling mechanism. The third rolling mechanism extends lower from the housing than the first rolling mechanism and the second rolling mechanism allowing the automated swimming pool cleaner to pivot about the third rolling mechanism. The drive mechanism rotates at least one of the first rolling mechanism, the second rolling mechanism, or the third rolling mechanism.

  • Patent number: 10161154
    Abstract: Exemplary embodiments include a pool cleaner having a body and articulated cleaning member extending from the body. The articulated cleaning member can be pivotally and/or rotatably coupled to the body. The articulated cleaning member can be pivoted or rotated with respect to the body to accommodate changes in the terrain of a pool. A method for cleaning a swimming pool is also provided where a pool cleaner having articulated cleaning members is submerged in a pool and allowing the pool cleaner to traverse an immersed surface of the pool. The method further rotates the articulated cleaning member in response to a difference in an elevation of the immersed surface between the articulated cleaning member and the body.
