ABSTRACT:
A swimming pool cleaning apparatus comprising a quick connect-disconnect handle, an ovate frame, a collecting net structure with an inner and outer section, and a blade-like edge on the forward portion of the frame. The collecting net structure contains an open inner net contained in a closed outer net; the inner net allows easy ingress of debris into the outer net while retarding its escape if the direction of net motion is reversed. The blade-like edge of moderately flexible material attached to the front of the net increases the efficiency of collection of debris close to the bottom walls of the pool. Construction of the apparatus is modular and allows easy replacement of worn parts without discarding serviceable parts; repairs can be made without the use of tools. The ease of assembly and disassembly allows the net to be stored and shipped in a disassembled state and is reflected in reduced handling costs.
