02 The different cleaning methods: suction or pressure
Print advice
The suction method
Cleaners using the suction method use the pool’s filtration system as a
source of power. They connect to the skimmer or the vacuum point and
work without the need for any additional equipment.
The power of
the pool’s pump enables them to move automatically and randomly, and to
suction debris, which is then sent to the pump basket. This means the
pump basket needs to be cleaned regularly. Backwashing the sand filter
is also essential.
These cleaners are very easy to install and use and offer a good quality-price ratio.
The pressure method
Cleaners using the pressure method also use the pools filtration system
as a source of power, but this method offers greater efficiency and
precision. Instead of being connected to the suction vacuum point, the
pressure cleaners are connected to a dedicated return line, or by
converting the suction vacuum point into a pressure vacuum point
(outlet). In this way, the skimmers stay active and retain all of their
surface filtration capacity. The cleaners can work with or without a
booster pump.
With booster pump:
The
hydraulic pressure cleaners work off high water pressure supplied by an
electric booster pump located near the filtration unit. The booster pump
recovers the water from the filter and sends pressurised water to the
pressure vacuum point, to power the cleaner. Booster pumps are usually
installed by a professional swimming pool contractor.
Without
booster pump:
The cleaner is connected directly to the
pool’s outlet. No other equipment is required.
In either
case, the cleaner moves randomly around the pool and suctions 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.
The pressure cleaners have a filter bag which collects the litter sucked up and so prevents the pump pre-filter from getting clogged.
Generally speaking, these cleaners are easy to use and offer an excellent performance-price ratio.
