I have the Dyson stick and this one I thought would be a better vacuum for pet hairs with the design of the roto head.  For that it does seem better but the rollers on the rotohead get clogged with hair!!  Also don't like the lack of thought into storing the unit while charging or when not in use.  They Dyson has a nice wall mount which is much nicer than leaning a vacuum on something to charge it.
