How does the water filter work?

The air that is vacuumed by the Polti Vaporetto Lecoaspira, together with the dirt, is delivered with a powerful jet into the dirt collector, creating a water vortex within it. The centrifugal force generated by the vortex forces impurities to the bottom of the collector, preventing them from being re-released into the home. That is why the water filtration system is particularly suitable for allergy sufferers.
