Abstract: A swimming pool accessory that is placed into and adjacent a sidewall of the pool includes a staircase assembly constructed from opposing sidewalls that support a plurality of steps that define an interior portion in which a filter assembly is mounted that includes a filter cartridge housing for receiving a removable filter cartridge, a pool skimmer having an inlet that is mounted through one of the opposing sidewalls and an outlet coupled to the filter cartridge housing, and a pump assembly having one end coupled to the filter cartridge housing and a second end forming a water discharge outlet and mounted to the other sidewall. The pump assembly includes a submersible water pump for drawing water through a filter cartridge positioned on the housing and pumping filtered water through the water discharge outlet to create a circulation of water about the interior periphery of the pool.
