Abstract: Swimming pool cleaners may operate autonomously within pools and spas. The cleaners need not include any external hoses or cords, and their bodies may be oriented at pool waterlines so as to make their on-board filters readily accessible for removal. The cleaners may dock at docking stations for various purposes, including (but not limited to) for charging any on-board battery and communicating electronically with the docking station or other external equipment.

Abstract: Debris filters for automatic swimming pool cleaners may be formed of metal, carbon fibers, or composites more rigid than soft nylon bags. In at least one version, the filter may be made of, or include, steel or stainless steel. Non-uniform sizes, densities, and/or shapes of openings in the filtration material may be created to provide different levels of filtration in a single device.
