Abstract
This patent application is assigned to Zodiac Pool Care Europe (Belberaud, Franc e). The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “Numerous cleaning devices capable of autonomous movement within swimming pools and spas currently exist. The most common of the se devices are APCs, which often are either hydraulic or robotic in type. Hydrau lic cleaners vary water flow for movement, while robotic cleaners typically empl oy electric motors to cause motion. Hydraulic APCs, furthermore, subdivide into “pressure-side” and “suction-side” cleaners, with pressure-side cleaners being f luidly connected to outputs of pumps of pool water circulation systems and sucti on-side cleaners being fluidly connected to inputs of such pumps.”
