Foot spa tub pump and method

A foot spa tub, comprising:

• a tub basin;
• a first magnetic drive member rotatably coupled to a drive motor;
• a first casing supporting said first magnetic drive member, said first casing disposed against an exterior surface of a sidewall of said tub basin;
• a second magnetic drive member rotatably coupled to a blade, said first and second magnetic drive members magnetically coupled to each other so that said blade is drivingly coupled to said drive motor;
• a frame having an upper plate with a side wall extending outwardly from an undersurface thereof to define a recess, said second magnetic drive member at least partially disposed within said recess;
• a nozzle housing said second magnetic drive member and said blade, said nozzle detachably securable to an interior surface of said sidewall by a magnetic attraction force between said first and second magnetic drive members;
• and
• at least one locking lever rotatably secured to a lower portion of said nozzle for locking said second magnetic drive member and said blade in said nozzle;
• said at least one locking lever including a cam portion pivotable against said frame for releasably securing said frame and said nozzle, and pivotable away from said frame for detaching said nozzle from said frame.
