Abstract (en)
[origin: US2015107012A1] Systems and methods for circulating water of swimming pools or spas are detailed. The systems may include both a main filtration pump and a secondary booster pump, with the booster pump containing a variable-speed motor. By adjusting motor speed of the booster pump, pressurized water may be supplied to certain automatic swimming pool cleaners more efficiently, without need for energy-wasting by-pass paths or restrictor plates.
