Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
206 words
A method of cleaning leaves and debris from the bottom of a swimming pool, comprising the steps of: connecting the mouth of a reticulated bag to the nozzle of an outlet hose of a swimming pool cleaner of the type that has a floating body, an inlet hose connected to a high pressure water supply, a flexible outlet hose for discharging high pressure spray for cleaning, and means for the body to self-propel itself about the swimming pool; the nozzle being oriented so as to direct water spray generally into the bag; lowering the bag to the swimming pool bottom with the bag oriented so that the hose nozzle is on the upper portion of the mouth; releasing the hose so that its weight causes the closed end of the bag to tip upwardly, with the mouth facing generally towards the swimming pool bottom and the nozzle on the forward portion of the mouth with respect to the spray, the rearward portion of the mouth being in contact with the swimming pool bottom; and providing water pressure to the swimming pool cleaner so that it will drag the hose and bag about the pool, the rearward edge of the mouth preventing leaves and debris from escaping.
Claim 2
Independent Claim
206 words
A method of cleaning leaves and debris from the bottom of a swimming pool, comprising the steps of: connecting the mouth of a reticulated bag to the nozzle of an outlet hose of a swimming pool cleaner of the type that has a floating body, an inlet hose connected to a high pressure water supply, a flexible outlet hose for discharging high pressure spray for cleaning, and means for the body to self-propel itself about the swimming pool; the nozzle being oriented so as to direct water spray generally into the bag; lowering the bag to the swimming pool bottom with the bag oriented so that the hose nozzle is on the upper portion of the mouth; releasing the hose so that its weight causes the closed end of the bag to tip upwardly, with the mouth facing generally towards the swimming pool bottom and the nozzle on the forward portion of the mouth with respect to the spray, the rearward portion of the mouth being in contact with the swimming pool bottom; and providing water pressure to the swimming pool cleaner so that it will drag the hose and bag about the pool, the rearward edge of the mouth preventing leaves and debris from escaping.
Claim 3
Independent Claim
180 words
A system for cleaning leaves and debris from swimming pools comprising: an automatic swimming pool cleaner having a floating body and means, supplied by water pressure, for self-propelling itself about the swimming pool; a flexible inlet hose connected to a high pressure water supply and to the floating body for supplying water; a flexible outlet hose connected to the floating body and having a nozzle for discharging high pressure spray; a reticulated bag connected to the nozzle of the outlet hose for being drawn about the swimming pool by the automatic swimming pool cleaner; the bag having an open mouth and a closed opposite end; connection means for connecting the nozzle of the outlet hose to the mouth, the nozzle pointing towards the closed end of the bag for directing leaves and debris into the bag; and flotation means, attached to the mouth of the bag, for allowing the bag to float semi-submerged, with a portion of the bag being above the surface for receiving floating leaves and debris directed into the bag by the spray from the outlet hose.
Claim 4
Independent Claim
180 words
A system for cleaning leaves and debris from swimming pools comprising: an automatic swimming pool cleaner having a floating body and means, supplied by water pressure, for self-propelling itself about the swimming pool; a flexible inlet hose connected to a high pressure water supply and to the floating body for supplying water; a flexible outlet hose connected to the floating body and having a nozzle for discharging high pressure spray; a reticulated bag connected to the nozzle of the outlet hose for being drawn about the swimming pool by the automatic swimming pool cleaner; the bag having an open mouth and a closed opposite end; connection means for connecting the nozzle of the outlet hose to the mouth, the nozzle pointing towards the closed end of the bag for directing leaves and debris into the bag; and flotation means, attached to the mouth of the bag, for allowing the bag to float semi-submerged, with a portion of the bag being above the surface for receiving floating leaves and debris directed into the bag by the spray from the outlet hose.
Claim 5
Dependent Claim
27 words
The system according to claim 2 wherein the mouth is rectangular and the flotation means comprises a pair of floats, one on each side of the mouth.
Claim 6
Dependent Claim
226 words
In combination with an automatic swimming pool cleaner of the type having a floating body, an inlet hose connected to a high pressure water supply, a flexible outlet hose with a nozzle for discharging high pressure spray for cleaning, and means for the body to self-propel itself about the swimming pool, a leaf and debris collecting device comprising: a reticulated bag connected to the nozzle of the outlet hose for being drawn about the swimming pool by the floating body; the bag having an open mouth and a closed opposite end; connection means for connecting the nozzle of the outlet hose to the mouth so as to direct the high pressure spray towards the closed end of the bag to direct leaves and debris into the bag; flotation means, connected to the bag, for allowing the bag to float semi-submerged, with a portion of the bag being above the surface for receiving floating leaves and debris directed into the bag by the spray from the outlet hose; the flotation means being detachable so that the bag may be drawn about the bottom of the swimming pool for collecting submerged leaves and debris; and scraper means, on the mouth, for scraping against the swimming pool bottom to prevent leaves and debris from escaping as the automatic swimming pool cleaner drags the bag along the swimming pool bottom.
