Abstract
An improved skirt for use with an automatic or robotic pool cleaner head comprising at least one or a row of double-hinged flaps, each of the flaps comprising a receiving member affixed to the pool cleaner head, an upper articulating member pivotally coupled to the receiving member, and a lower articulating member pivotally coupled to the upper articulating member. The pivotally connected members form upper and lower hinges which allow free radial movement upward to, but not beyond, the bottom surface of the pool cleaning head, and further allow the cleaning head to navigate uneven surfaces or pieces of debris while maintaining effective suction.
