I can not recommend the device, unfortunately. Had to buy directly times sucked my mattress and wondered how little stuff in the filter hung. (To my knowledge, the mites can be seen as a fine dust in the filter but .. I just saw n bissle fluff and a few hairs) ... Yesterday I a. Dyson DC52 bought and the first idea was to suck the mattress because the transparent collecting container ... and I was very shocked when I saw how much fine dust from the mattress And arrived .. The Jolta Milbensauger has simply too little Saugleißtung .. moreover the UV lamp to get used to because it is backed up with multiple contacts and immediately disappears when the vacuum cleaner is not pressed continuously laid on the mattress. I am not convinced of the product ..
