Have had this model for almost a year and am mostly happy with it. Good power; battery lasts well beyond the time needed for area cleaned; sucks up as much dirt as dog hair, which is what you would expect from a Dyson.  I've only two complaints: 1) they have made the body longer, and therefore too heavy for one-handed use (in my opinion, at least), and 2) after all these years, Dyson STILL has not made an on/off switch that stays on until turned off (causes a lot of strain in my arthritic thumb).
