Especially for large pools - the set is recommended for pools with a diameter up to 488 cm. The supplied filter element filters the dirt particles in the water, such as leaves and insects, directly over the water surface into the filter element. This way you achieve a very effective water purification. With the adjustable telescopic bar you can easily reach even dirt particles far inside the pool. The included vacuum cleaner is ideal for cleaning the pool floor. After some time a slippery algae layer can form here. They immediately suck off the dissolved material via the attached hose of the suction cup and clean the water via the supplied filter element.
