  • Patent number: 9714639
    Abstract: Some embodiments provide a pool cleaner generator module with magnetic coupling. The generator module can include a housing, a paddle wheel, a magnetic follower, and a generator. The generator can power components of the pool cleaner, such as light emitting diode (LEDs). The housing can be removably coupled to the pool cleaner and can include a flow directing portion positioned in a fluid path of the pool cleaner. The paddle wheel can be located adjacent to the flow directing portion and can rotate in response to fluid flow through the fluid path. The generator can be magnetically coupled to the paddle wheel and can generate power through rotation of the paddle wheel. The LED can be coupled to the generator and can receive the generated power from the generator to illuminate an area adjacent to the pool cleaner.
