Boosterless Water Pressure Designs

Booster Type

Some automatic cleaners work like your leaf vacuum, by sending a pressurized stream of water up into a catch bag, creating a vacuum for the unit as it patrols the bottom. The pressure is created by taking return water and boosting the pressure with a separate pump and motor. This is the boostered type of automatic cleaner.

Boosterless

But in the Boosterless water pressure design there is a small variation in the unit that uses the circulation pump itself as the booster, by connecting to the return line after the pump but before the filter. This style is called boosterless because it uses no separate water pressure boosting device. These units require an automated valve and control system so that the heater doesn't try to operate while the cleaning unit is in operation. This is the drawback of the system. If the cleaner and heater are on simultaneously, the cleaner receives the return water before the heater, thus starving the heater. Low water circulation in the heater will cause it to shut off or overheat. Boosterless cleaners are not popular units because you can't filter and heat the water at the same time you vacuum debris, and also additional expensive plumbing and controls are needed.
