I'm not new Dyson user, but I must say that the DC 51 is so far my favorite. Between the sled model certainly massive and powerful but little maneuverability, and small DC 34 impractical for soil, now I control the DC51. And what if I was first surprised by its compactness. Then maneuverability is remarkable thanks to the Dyson ball technology. No complaints about power, iron from launches of the brand. And finally, it is a model very clever with its extendable hose and telescopic handle hidden in its handle. A must have.
