Abstract
The assignee for this patent application is Zodiac Pool Care Europe (Belberaud, France).Reporters obtained the following quote from the background information supplied by the inventors:“Numerous cleaning devices capable of autonomous movement with in swimming pools and spas currentlyexist. The most common of these devices are APCs, which often are either hydraulic or robotic in type.Hydraulic cleaners v ary water flow for movement, while robotic cleaners typically employ electric mo torsto cause motion. Hydraulic APCs, furthermore, subdivide into “pressure-side ” and “suction-side” cleaners,with pressure-side cleaners being fluidly connect ed to outputs of pumps of pool water circulation systemsand suction-side cleane rs being fluidly connected to inputs of such pumps. Traditional APCs may include asingle on-board battery pack such that the APC does not require cabling for r eceiving power from outsidethe pool or spa. However, APCs for large pools may r un out of charge before completing an operationsuch as a cleaning cycle, thereb y requiring an interruption to the cleaning cycle such that the APC canbe recha rged.”
