Abstract
Reporters obtained the following quote from the background information supplied by the inventors:“Traditional devices for automatic pool cleaning are generally intended for cleaning bottom of pools.While some are designed to clean the sur face of the pool water surface, they suffer from become trappedin tight comers or at other obstacles. These devices are often unable to free themselves to navi gate awayfrom obstructions. Such devices typically have no directional control and no intelligence. They generallyrely on mechanical means, such as arms, bump ers, or wheels to redirect themselves after encountering apool wall. Without in telligent directional and navigational control, traditional devices generally tr avel thesame route repeatedly without covering and cleaning the entire pool sur face.
