Abstract
Disclosed are filter systems and methods for swimming pools and spas for leaves and other larger debris. The disclosed filtering devices may be provided in-line with a pool cleaning or filtering system such that filtering devices pre-filter the larger debris before the pool cleaning or filtering system filters smaller debris. In some cases, the filtering devices provide an airtight seal that is easy for a user to open or close as desired. In some cases, the disclosed filtering devices include a filter between an inlet and an outlet that are parallel to and offset from a center axis of the filter. In some cases, the filtering devices are configured to generate horizontal cyclonic flow of water.
