ABSTRACT:
A pool or tank cleaner that is propelled by means of one or more water jets is directed in one or more predetermined systematic scanning patterns of either straight, curvilinear, or combinations of both, by an apparatus and method that controls and varies the directional discharge of one or more water jets that propel the cleaner in its translational movement. The direction of the discharge of the propelling water jet is changed by mechanical sensors, electrical sensors, or by interrupting the water pump. Further variations in the direction of translational movement of the cleaner are effected by activating at least one retractable depending member to periodically contact the pool surface below the moving cleaner, thereby causing the cleaner to pivot or otherwise change direction.
