A pool cleaning system for cleaning debris from a submerged surface of a swimming pool includes a self-propelled pool cleaner having rotatably-mounted supports for supporting and guiding the cleaner on the pool surface; an electric motor for enabling the rotation of the rotatably-mounted supports on the pool surface; at least one camera to capture imagery of the pool surface; a controller, in electronic communication with the at least one camera, to determine a cleanliness characteristic of the pool surface on which the cleaner has passed based on the camera imagery and generate a control signal to direct movement of the cleaner based on the cleanliness characteristic of the pool surface, and a portable electronic device configured to present a graphic on a display, the graphic depicting the submerged surface of the pool and those portions of the surface that remain uncleaned as the cleaner traverses the pool surface.

An endless track belt for a submersible, autonomous vehicle is disclosed. The track belt includes an outer surface with raised track elements that are configured to both engage a supporting surface and selectively receive external grip elements configured to engage the supporting surface. The track belt also includes an inner surface with continuous, annular ridges. The continuous ridges are configured to secure the endless track belt to a drive pulley in a manner that prevents lateral movement while allowing for some longitudinal slip during rotational movement of the belt.

A self-propelled robotic cleaning apparatus for cleaning a submerged surface of a pool or tank includes a housing defining an interior chamber containing a filter assembly for filtering water flowing through at least one water inlet formed in the base plate. A filter backwash assembly is positioned within the interior chamber and has at least one fluid discharge outlet for providing a pressurized flow of a fluid towards the exterior surface of the filter assembly as a backwash to rinse and dislodge the debris therefrom.

A pool cleaning system for cleaning debris from a submerged surface of a swimming pool includes a self-propelled pool cleaner having rotatably-mounted supports for supporting and guiding the cleaner on the pool surface; an electric motor for enabling the rotation of the rotatably-mounted supports on the pool surface; at least one camera to capture imagery of the pool surface; a controller, in electronic communication with the at least one camera, to determine a cleanliness characteristic of the pool surface on which the cleaner has passed based on the camera imagery and generate a control signal to direct movement of the cleaner based on the cleanliness characteristic of the pool surface, wherein the control signal directs movement of the cleaner to reclean a portion of the pool surface where the cleanliness characteristic fails to satisfy a predefined threshold.

A robotic pool or tank cleaner is propelled by water jets, the direction of which is controlled by the direction of rotation of a reversible pump motor that is horizontally mounted in the pool cleaner housing that has a propeller attached to either end of the motor drive shaft which projects from opposing ends of the motor body, each of the propellers being positioned in, or near a water jet discharge conduit that terminates in discharge ports at opposite ends of the housing. Each discharge conduit has a pressure-sensitive flap valve downstream of the respective propellers. When the propellers rotate in one direction, the water is drawn through one or more openings in the base plate, passes through one or more filter assemblies associated with the pool cleaner and is discharged through one of the discharge ports as a water jet of sufficient force to propel the pool cleaner.

A pool cleaning system utilizes a powered robotic surface cleaning vehicle to travel adjacent water containing surfaces of a pool while submerged within the pool. In one implementation, a camera captures movement of the vehicle. In one implementation, a dry station serve the intermediary across a wide area network between the vehicle and a server which communicates with the portable electronic device.

A self directed pool cleaning vehicle comprising a body carrying water inlet and outlet ports with the inlet port being located on the bottom of the body with the body containing a filter is described. A drive mechanism propels the vehicle in two generally opposed directions. Two axles which each carry two wheels support the body and control its direction of movement. One axle is mounted to the body via slots that extend in the directions of motion such that this axle can move toward either end of the slots. A steering structure is provided with a portion that moves to close a portion of one of the slots and can be locked in a position that prevents one end of an axle from traversing its slot. Thus when this axle is the trialing axle it is held at other than a right angle to the two generally opposed directions.
