The hydraulic pressure cleaners are powered by high water pressure supplied by an electric booster pump located near the filtration unit.The cleaner moves randomly around the pool and sucks in debris using a principle known as the venturi effect, which is created inside the cleaner and converts the incoming water into a powerful suction current. This method ensures maximum efficiency in minimum time. Pressure cleaners feature a filter bag which collects the debris sucked up and prevents the pump pre-filter from getting clogged.
