I bought it a few years ago, the first dyson out on the market, after many years of use, I opted for other brands, which seemed to use the same technology, but then: disappointment! lack of power, tedious cleaning of filter, it wasnt that short blades copies of Dyson. The price of this product is more reasonable, it is with great pleasure that I found the effectiveness of the cleaner, INIMITABLE! Fast delivery, one day before the deadline, proper packaging, available stock, control information monitoring: efficient, it can not be said of some retailers that sell household electro, and sétonne success amazon! !!
