ABSTRACT:
A suction head for use in vacuum cleaning a swimming pool bottom intended to avoid clamping of the sweep to the pool bottom. A generally rectangular flexible platform is supported for forward and backward motion perpendicular to the longitudinal axis of the platform while being maintained in spaced parallel relation above the pool bottom. A central opening in the platform is connected to a suction line. Pairs of transverse ribs extending upwardly on the platform are positioned adjacent the opening. A pole for moving the sweep across the pool bottom is pivotally connected to a pillar projecting vertically from the pool sweep adjacent the opening, by a horizontal rigid pin passing transversely through the pillar and through a yoke connected to the adjacent end of the pole. The ends of the pin contact the ribs adjacent the opening and substantially prevent longitudinal flexing of the platform in the region adjacent the opening. By preventing longitudinal flexing in the region adjacent the opening the problem of clamping, i.e. having the underside of the platform moved into contact with the pool bottom, is avoided.
