Abstract
A pressure type pool cleaner includes a head propelled forwardly over a surface. Different portions of water pumped to the head inducts debris into a cleaner system, and is ejected via a thrust nozzle onto a deflector and thence along a thrust line to thrust the head along the line. The deflector is pivotal via a saddle about a longitudinal axis such as to be displaced laterally relative to the thrust nozzle. The deflector includes obliquely opposed deflection surfaces which are respectively aligned with the nozzle in dependence on its relatively laterally displaced position to deflect the water ejected along the line to respectively different oblique directions to adjust the direction of thrust and to effect lateral steering.
