This unit is to replace the V10 that has been discontinued and so far after 1 month of use seems compatible but did not receive all of the same accessories that the V10 had,
I bought my Dyson about a month ago and my wife and I are happy with our purchase. We like the cordless feature and that it is light weight. It works great!
I bought a V11, it's been a 1.5 months and honestly is such an investment. I have two cats and I needed to remove the hair easily through out the week... I vacuum the floor, carpets, sofa & the bed and doing it twice a week has made a huge difference. It lightweight, easy to use, appliances are very useful. I like it and will keep using it a lot.
