Abstract
Disclosed herein are a steering system for a suction cleaning device, a locomotion system for a pool cleaner, and a turbine for use in an automatic cleaner. The steering system includes a fluid driven turbine that rotates a cam gear that is interconnected with a cam wheel for directing a drive pinion. The drive pinion is positionable in a plurality of positions to drive a nose cone that steers the suction cleaning device. The locomotion system includes first and second A-frame arms that respectively engage first and second bearings about first and second eccentrics of a turbine. Rotation of the turbine causes the first and second A-frame arms to rotate back and forth driving associated walking pod assemblies. The turbine includes a turbine rotor and a plurality of vanes connected to the turbine rotor. The plurality of vanes including lateral edges having lateral open regions to facilitate debris-removing efficiency.
