Abstract
Automatic swimming pool cleaners are detailed. The cleaners may employ filter bags with novel stiffeners to help retain their optimal debris-collection shapes in use. They additionally may include bags made of material having sanitizing properties or additives, allowing water sanitization to occur as water flows through the bags themselves. Cleaners described herein further may include discs having generally radial but non-linear slits to facilitate navigation in particular conditions and fix buoyant material within a collar by which a bag is attached to a body of the device.
