Abstract:
A swimming pool cleaner operable through a vibratory movement thereof, the swimming pool cleaner comprising:a housing; vibrating means carried by the housing for providing a vibratory movement thereto; a friction support carried by the housing for operably engaging a surface to be cleaned, the friction support having a first portion attached with the housing and a second portion having a free end in frictional contact with the surface to be cleaned; and biasing means for biasing the friction support toward a first orientation and limiting movement thereof, which movement displaces the free end and thus the friction support from the first orientation to a second orientation, wherein the biasing means is integrally formed with the friction support in a one-piece construction for an elastically deforming thereof to produce a resultant force capable of moving the swimming pool cleaner in step by step increments in a forward direction.
