A suction head for a swimming pool cleaner comprising a housing which is open at its lower side and has inclined bristles attached to its lower edge for supporting on a surface to be cleaned. The housing has a rotary sleeve mounted to its top for connection of a suction hose in turn to be connected to a water suction pump. Said sleeve opens in a chamber within the housing in which a vibratory element is pivotally mounted, said element having a crescent or air-foil shape. By a flow of water sucked through said chamber, the vibratory element is automatically brought into a vibrating movement which imparts pulsations on the suction head. Thereby, the inclined bristles are bent and straightened repetitively, resulting in a forward thrust moving the suction head over the surface to be cleaned. At least one foot is disposed in the housing which is cyclically displaced vertically by a driving mechanism driven by the movement of the vibratory element and returned by return springs. Said foot cyclically lifts off the suction head at one side, resulting in a rotational movement of the suction head about a vertical axis so as to change the direction of forward movement of the suction head.
A suction head for a swimming pool cleaner comprising a housing which is open at its lower side and is limited there by a lower edge and has a rotary connecting sleeve for connecting a suction hose rotatably mounted to its top, said connecting sleeve opening into a chamber formed in the housing, said chamber being open at its lower end, a vibratory element pivotally mounted in a horizontal axis in said chamber and adapted to automatically pivot to and fro in a vibrating movement if a water flow through said chamber from the lower end to said connecting sleeve is established by means of an external suction pump connected via said suction hose to said connecting sleeve, said vibrating movement of the vibratory element causing a sympathetic vibration of the suction head, and flexible bristles attached to the lower edge of said housing and projecting downwardly from said housing, the free ends of said bristles being adapted to support said suction head on a surface to be cleaned and being arranged in a common plane, and said bristles being inclined in a specific common direction so that they enclose an angle deviating from the vertical onto said plane defined by the free ends of said bristles.
In a swimming pool cleaner suction head of the type having a housing forming a chamber open at its lower side and a connection for a hose by which a remote suction pump establishes a water flow through the chamber and into the hose, the improvement comprising:
