After long compared to the Dyson model. The value for money of this vacuum cleaner is best. (Almost 1/2) It is easy to use and very effective. The rotary system seems gadget at first but is very convenient. To see if this system remains reliable over time. Only small flat, relatively noisy. A perfect vacuum level and a system for the efficient emptying. No regrets. Delivery within 48 hours and interesting price level. no complaints.
