Abstract: The improved system includes a poolside vacuum-generating machine having a vacuum-generating power source, filter, waste disposal means and a passageway through the casing; a lead weighted vacuum head which may be flexible and is adapted to sit on a pool bottom, and includes a stem defining a vertical suction passageway therethrough; a flexible conduit connected at its upper end to the machine; and, a universal ball joint connector connected to the lower end of the flexible conduit and to the vacuum head stem, so as to permit universal rotation of the head for better pool bottom cleaning. The connector includes a ball joint component with central vertical passageway, an upper cup-shaped conduit-receiving end and a lower end with rounded outer surface, and a sleeve the upper end of which bears a curved annular insert bearing against and holding the ball joint components rounded outer surface in place. The lower end of the sleeve is secured to the vacuum head stem.
