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.
