METHOD AND APPARATUS FOR IMPROVING PERFORMANCE OF SUCTION POWERED POOL CLEANING SYSTEMS

摘要

A pool cleaning system including means responsive to the magnitude of negative pressure at the suction inlet of a system pump for controlling pump water flow in order to prevent pump cavitation. Systems in accordance with the invention are configured to pump a high rated volume of water when operating in a filtering mode and to provide a high negative pressure to power a pool cleaner when operating in a cleaning mode.
