DELPHIN is an appliance for lasting cleanliness and well-being. Water cleans the air. Water binds allergens and dust. Air purifier, vacuum cleaner and mop in one appliance. Wiping only one operation! Vacuum cleaners become superfluous and that without filter and without follow-up costs. 1#The DELPHIN from PROAIR is a water-based air purifier. At the same time you can use it as a vacuum cleaner. Or you can mop your floor. Very interesting if you have allergies, aspiration problems, children, pets
