Abstract

Devices combining swimming pool skimmers, pumps, and removable, disposable filters into integral, sidewall-mounted systems for above-ground pools and other above-ground liquid containment enclosures, and methods for the use of such systems to remove both larger floating debris and smaller particulate matter to maintain water clarity and hygienic safety within such pools or like liquid containment enclosures are disclosed herein. Specifically, a ring-type above-ground pool comprising a base, a sidewall, and at least a portion of a cleaning system solely supported by the sidewall and mounted at a non-vertical angle such that it is substantially parallel to the sidewall.
