    • 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.
    • 压力式游泳池清洁器包括在表面上向前推进的头部。 水泵送到头部驱动轮子涡轮机时尚; 将碎屑引入清洁系统; 并通过推力喷嘴喷射到引导件上,然后沿着推力线推动头沿着该线。 枢轴导向器安装引导件并且包括暴露于水的表面构件。 在向前运动期间,构件上的水压抵抗引导件上的喷射流压力,并且将导向件的取向保持在推力线的正上方,从而在轮的旋转轴线附近通过。 当障碍物阻止向前运动时,构件上的压力及其反作用力停止,引导件被重新定向并将推力重定向到轴线以下,以使头围绕轴线枢转以辅助车轮缩放障碍物。
