Especially for large pools - the set is recommended for pools with a diameter of 549 cm or more. The supplied filter element filters the dirt particles in the water, such as leaves and insects, directly over the water surface into the filter insert. This enables you to achieve very effective water purification. The adjustable telescopic pole allows you to easily reach dirt particles far inside the pool. The vacuum cleaner supplied is ideal for cleaning the pool floor. A slippery layer of algae can form here after a while. You suck up the loosened material immediately via the attached hose of the vacuum cleaner and clean the water via the supplied filter element.
