Abstract
A pressure type pool cleaner includes a head propelled forwardly over a surface. Water pumped to the head drives wheels turbine fashion; inducts debris into a cleaner system; and is ejected via a thrust nozzle onto a guide and thence along a thrust line to thrust the head along the line. A pivoted director mounts the guide and includes a surface member exposed to the water. During forward movement, water pressure on the member counteracts jet stream pressure on the guide and maintains the guide's orientation for the thrust line to pass closely above a wheel rotation axis. When an obstacle stops forward motion, pressure on the member and its counteracting stop, the guide is reoriented and redirects the thrust to well below the axis to pivot the head about the axis to assist the wheels to scale the obstacle.
