Abstract: A set of pool cleaning robots for cleaning a pool, wherein a first pool cleaning robot of the set and a second pool cleaning robot of the set are configured to clean different regions of the pool.

Abstract: A method and a set of pool cleaning robots for cleaning a pool. The set includes a first pool cleaning robot and a second pool cleaning robot that differ from each other by at least one unit out of a propulsion unit and a cleaning unit. Each one of the first pool cleaning robot and the second pool cleaning robot includes a filtering unit, a housing, and a controller.

Abstract: A set of pool cleaning robots for cleaning a pool, wherein the set includes a master pool cleaning robot and a slave pool cleaning robot.

Abstract: A system for maintaining a pool cleaning robot, the system may include a cover, a cleaning unit that is positioned within a space and a cover manipulator, wherein the cover manipulator is configured to move the cover between a first position in which the cover prevents the pool cleaning robot from entering the space and a second position in which the cover defines an opening through which the pool cleaning robot passes to enter the space.

Abstract: An information system for dynamic distribution of location-related information between users with different perspective views includes a number of user units each including a viewing arrangement defining a viewing direction and a registration subsystem for deriving a mapping between the current perspective view and a shared location reference. The user units also include a data management system and a wireless communication arrangement. At least one of the user units further includes a user input interface for designating a viewed location within the current perspective view for association with location-related information to generate a new location-related information entry for sharing with others of the plurality of user units. At least one other of the user units further includes a display device associated with the viewing arrangement for displaying location-related information correctly positioned in the context of the current perspective view.
