Abstract
A pool vacuum comprises an elongated pipe section having a flattened debris pickup end and a discharge end for discharging debris into a bag which is removably attached to the pipe section. Intermediate the ends of the elongated pipe section is a larger pipe section which is spaced from and sealed to the elongated pipe section to form a fluid discharge chamber surrounding the elongated pipe section. Apertures are formed between the chamber and the discharge end of the elongated pipe section to direct fluid applied under pressure to the chamber rearwardly through the elongated pipe section. This creates a partial vacuum for causing debris located near the pickup end of the elongated pipe section to be sucked up and directed into the bag whenever fluid under pressure is supplied to the chamber.
