Never used Dyson open face motorized brushless power head.
For Dyson V7 V8 V10 V11.

I have a V7 in my trailer and a V10 down stairs. The V11 that we use the most is upstairs and I use the same as this one. I actually like it better because the throat and hose in the power head are much larger and doesn't get jamed up as much as the Dyson one. I can pick up much larger debris like if I dump a bag of Fruitloops it will suck it all up with out plugging up in the power head. That's what I love about the open face you can approach a tall pile and not shoot them all over the place it just pulls it all right under.
