A suction type turbine-driven pool-cleaners utilizing vortex turbines to propel and steer the pool cleaner is disclosed. The cleaner includes a housing for one or more vortex-turbine mechanisms, each with a chamber and a turbine, tracks for movement over submerged surfaces, a differential mechanism for steering purposes, a reverse of inlet flow mechanism, a cam design for engagement of steering and reversing mechanisms, a means of controller inlet flow for steering purposes, and a means of controlling flow for reversing direction of cleaner movement.
