Abstract
A vacuum cleaner head, for use in cleaning submerged surfaces of swimming pools, has a body the lower surface of which is supported a selected distance above a support surface, such as a pool floor, by wheels carried by the body. Resilient seal means depend from the body along front and rear edges thereof into close cooperation with the support surface to define essentially sealed side walls of a chamber which has the support surface as its bottom and the body lower surface as its top. The chamber is open at its ends which are generally at the ends of the head body. A water suction port is provided through the body from the chamber between the chamber ends; the port is connectible to a water suction hose. When the cleaner head is in use, water flows into the chamber essentially only through the open ends of the chamber and then to the suction port. The cleaning effectiveness of such water flow on the pool surfaces is of increased uniformity so all portions of the pool surface traversed by the chamber, as the head is moved on the pool surface, are cleaned substantially equally well.
