A pedicure spa or hydrotherapy system for circulating fluid which includes a motor coupled magnetically with an impeller assembly on the wall of the pedicure spa or hydrotherapy system is disclosed. The system is designed to have low energy consumption and an ultra low profile while at the same time providing a pipeless water circulation that is easy to operate and clean. In addition, the invention minimizes the growth of bacteria within the pumping system as the impeller assembly is easily removed from the wall for cleaning without any mechanical aids. In certain embodiments, the magnetic propulsion and coupling device includes a multi-directional combination of strategically placed and alternating-pole magnets on magnet plates and additional magnets in the housing.
