ABSTRACT:
A net for removing debris is mounted on a frame which is extendable across the width of a swimming pool. The frame has a rounded or ball-type element at each lower end which rotates about an axis to facilitate travel and to protect the swimming pool surfaces from damage as the swimming pool cleaning device is moved through the water during a cleaning operation. Handles are provided for pulling the net through the water by persons on opposing sides of the pool. The pool may be cleaned in a single pass across the length of the pool. The net may be completely or partially rolled up about at least one of the side members of the frame.
