A swimming pool cleaner of the type movable along an underwater pool surface to clean debris therefrom. The pool cleaner includes a body having a debris inlet and a debris outlet. A rigid debris-collection canister is secured to the body over the debris outlet to collect debris in the rigid canister and pass filtered water either back into the pool or to a remote suction system such that the collected debris remain at the pool-cleaner body for easy maintenance while allowing free flow of water through the rigid canister. The rigid canister is shaped to minimize obstructions to the pool cleaner movement in the pool by providing improved buoyancy and limiting entrapment of the cleaner by underwater pool structures. The cleaner body is adapted for securement of either a water-suction hose connected to a remote suction system or a venturi-line structure connected to a water-flow line fed by a remote pump such that the pool cleaner is interchangeably usable as a suction cleaner and as a pressure cleaner.

The pool cleaner of claim 3 wherein the rigid debris-collection canister includes an o-ring gasket seal between the base and cover portions. 5. In a swimming pool cleaner of the type movable along an underwater pool surface to clean debris therefrom, the pool cleaner being a pressure cleaner and comprising: a body having a debris inlet and a debris outlet, the body including a venturi structure configured for drawing debris into the body through the debris inlet; anda rigid debris-collection canister having (a) a base portion removably secured to the body over the debris outlet to collect debris in the rigid canister and (b) a cover portion movably connected to the base portion, the cover portion having a series of apertures for passing filtered water back into the pool such that collected debris remains at the pool-cleaner body for easy maintenance while allowing free flow of water through the rigid debris-collection canister. 6. The pool cleaner of claim 5 wherein the base portion of the rigid canister has a solid structure to retain fine debris therein. 7. The pool cleaner of claim 6 wherein the cover portion includes a fine mesh insert positioned opposite the debris outlet to entrap fine debris such as sand and pollen. 8. In a swimming pool cleaner of the type movable along an underwater pool surface to clean debris therefrom, the pool cleaner including a body having a debris inlet and a debris outlet, the improvement comprising: a rigid debris-collection canister secured to the body over the debris outlet to collect debris in the rigid canister and pass filtered water either back into the pool or to a remote suction system such that collected debris remains at the pool-cleaner body for easy maintenance while allowing free flow of water through the rigid canister, the rigid canister includes a base portion and a cover portion connected to the base portion, the base portion including an L-shaped protrusion extending from a base-portion edge, the cover portion defining an aperture configured to receive the L-shaped protrusion therein, thereby forming a hinge connection between the base and cover portions. 9. The pool cleaner of claim 8 wherein the rigid canister has a debris-receiving region about the debris outlet and a debris-collecting region extending from the debris-receiving region along the body of the pool cleaner, the rigid canister being configured such that debris flows from the debris-collecting region toward the debris-receiving region to fill up the canister substantially uniformly and substantially free of interference with pool-cleaner operation. 10. The pool cleaner of claim 9 wherein the hinge connection is positioned at an end of the canister which is opposite the debris-collecting region. 11. The pool cleaner of claim 10 wherein the canister includes a retaining latch for securely locking the base portion to the cover portion during the pool cleaner operation. 12. In a swimming pool cleaner of the type movable along an underwater pool surface to clean debris therefrom, the pool cleaner including a body having a debris inlet and a debris outlet, the improvement comprising: a rigid debris-collection canister secured to the body over the debris outlet to collect debris in the rigid canister and pass filtered water either back into the pool or to a remote suction system such that collected debris remains at the pool-cleaner body for easy maintenance while allowing free flow of water through the rigid canister;an attachment mechanism locking the rigid canister to the pool cleaner body, the attachment mechanism including (a) a connector mechanism secured to the debris outlet and defining a pair of oppositely-positioned slots and (b) a locking mechanism forming a pair of oppositely-positioned locking projections, the locking mechanism being configured to snap the projections into the corresponding slots of the connector mechanism for securely attaching the rigid canister to the pool cleaner body for operation and to withdraw the projections from the slots for detaching the rigid canister from the cleaner for emptying and pool cleaner maintenance. 13. The pool cleaner of claim 12 wherein the rigid canister includes a base portion and a cover portion connected to the base portion. 14. The pool cleaner of claim 12 wherein the locking mechanism includes a pair of locking members each including one of the locking projections, each locking member having (a) a fixed end secured to the rigid canister and (b) a free end, in a released state the locking members maintain the projections in the corresponding slots and when the free ends are pressed toward each other the projections are withdrawn from the slots thereby releasing the rigid canister from the cleaner body. 15. The pool cleaner of claim 14 wherein each of the locking members includes a finger grip at its free end for a simple finger pressing of the free ends toward each other to withdraw the projections from the slots to detach of the rigid canister from the pool-cleaner body. 16. The pool cleaner of claim 14 wherein: each fixed end of the locking member defines a hole therethrough; anda fastener stud extends through the holes and a canister wall, thereby affixing the fixed ends to the rigid canister. 17. The pool cleaner of claim 16 wherein the fastener stud has a U-like shape and includes a gripping wedge extending outwardly substantially perpendicular along each leg of the U-shaped stud and sloping to terminate at the end of the leg, the perpendicular surfaces of the wedges engaging an interior surface of the rigid canister, thereby securely mounting the locking mechanism to the rigid canister. 18.
