Having had several recommendations for buying a Dyson from several members of my family and friends, my choice is given to this model, and frankly I'm not disappointed. Excellent suction power, excellent handling and frankly not louder than another. In addition to a guaranteed 5 years by Dyson who parentheses a very good service. I highly recommend this vacuum cleaner for people who want quality, robustness and want to make a long-term purchase.
