ABSTRACT:
A device for cleaning leaves and debris from swimming pools comprising a reticulated bag having an open mouth and closed end. The mouth is connected to the nozzle of a high pressure water hose, which in turn is connected to an automatic swimming pool cleaner of the type that floats and propels itself about the pool by means of a high pressure water supply. A flotation collar is connected to the bag so that it will float semi-submerged, a portion of the mouth being above the water to trap floating leaves and debris. The flotation collar is detachable so that the hose and bag will sink for cleaning the bottom of the pool. The hose is sufficiently flexible and weighted so that the bag can tip upward while on bottom, with the mouth facing the bottom and the hose on the forward side of the mouth. The rearward side of the mouth scrapes the bottom, aiding in trapping leaves from the bottom as the swimming pool cleaner drags the hose and bag about the pool.
