This was a replacement for the V12. This model is larger then the V12. A lot heavier and awkward to use. I am not fond of the new power head. This has the larger rubber wrap on the back side. When operating, it will stop the rotary due to the amount of suction it creates. However, I do like the canister clean-out better.
This vacuum is a dream on wood floors. I love that I can see all the dust and hair before it sucks it right up. But it is kinda of a pain on carpet. You will need some strength to push it forward.
I bought this about a month ago, after spending about a month trying to decide which one to buy. Finally decided to go with this model and am very happy. I was a little concerned about the weight after reading other reviews but the weight is not a problem. The vacuum seems to glide on all hard surfaces. There is an adjustment for carpeted areas. The attachments are easy to switch, the suction is very good and I really like the green light that shows all of the fine dirt particles (that our eyes don’t see). The battery life lasts so I am able to vacuum the entire house, but our home isn’t large and all on one level. And, it is simple to empty.
This is my 3rd Dyson, I love it, very light, truly gets every speck of dust gone, easy usage, love the attachments, long battery usage, Easy to move excellent !!!!!!
