Pool cleaner generator module with magnetic coupling

A generator module for a swimming pool cleaner, comprising:

• an outer housing including a generator housing and a flow directing portion, the flow directing portion positioned in a fluid flow path of the swimming pool cleaner;
• a paddle wheel positioned around a drive shaft, the paddle wheel including magnets embedded into the paddle wheel;
• a generator enclosed within the generator housing and in communication with a driven shaft so that rotation of the driven shaft causes the generator to produce electric power;
• electronic circuitry configured to be driven by an alternating electric current converted from an alternating magnetic field;
• and
• at least one light emitting diode that emits light in a first manner if a first swimming pool cleaner operational condition is present and emits light in a second manner different from the first if a second swimming pool cleaner operational condition is present.

A pool cleaner for a swimming pool or spa, the pool cleaner comprising:

• a fluid flow path;
• a light emitting diode positioned to direct light toward one of walls and a floor of the swimming pool or spa;
• a generator module that powers the light emitting diode, the generator module including:
• an outer housing including a generator housing with a paddle wheel end and a lead cover end, and a flow directing portion positioned in the fluid flow path, the outer housing configured to be coupled to a supply mast of the swimming pool cleaner,
• a paddle wheel positioned around a stationary drive shaft, the paddle wheel including a magnet section having at least one drive magnet and rotating in response to fluid flow through the fluid path,
• a generator enclosed within the generator housing by a lead cover on the lead cover end and in communication with a driven shaft so that rotation of the driven shaft causes the generator to produce electric power, and
• a magnetic follower coupled to the driven shaft and including at least one follower magnet, the magnetic follower being substantially encircled by the magnet section of the paddle wheel, the at least one follower magnet being magnetically coupled to the at least one drive magnet of the paddle wheel so that rotation of the paddle wheel causes rotation of the magnetic follower and the driven shaft.
