Abstract
News editors obtained the following quote from the background information suppli ed by the inventors:“Numerous cleaning devices capable of autonomous movement w ithin swimming pools and spas currentlyexist. The most common of these devices are APCs, which often are either hydraulic or robotic in type. Hydraulic cleaner s vary water flow for movement, while robotic cleaners typically employ electric motorsto cause motion. Hydraulic APCs, furthermore, subdivide into “pressure-s ide” and “suction-side” cleaners,with pressure-side cleaners being fluidly conn ected to outputs of pumps of pool water circulation systemsand suction-side cle aners being fluidly connected to inputs of such pumps. While current APCs collec tdebris from the pool or spa, they do not get feedback about the collected debr is and/or water flowingthrough the APC.”
