Part of the water filtration system in vacuum cleaners with cyclone aqua filter.
Only 2 litres of normal water are required for the cyclone aqua filter to work effectively.
In the aqua filter´s mixing chamber dust, that gets inside along with air flow, mixes with water and transforms into liquid dirt. The finest dust that does not get wet is retained by the fine dust filter. In this way, dust stays inside the vacuum cleaner and purified air goes back to the room.
