I finally upgraded after having my last cordless Dyson for the last 7 years, and I can't believe how much better this model is! I love that it measures how much it collects, although I got a little obsessed with this feature the first few times I used it! I hoover everyday due to having a dog and I thought my house was pretty spotless, so I couldn't believe how much dirt this collected the first time I used it; it was completely full after 25 minutes! I also love that the small attachment is now tucked inside the long tube, so I don't have to carry it around with me to swap it over as I go.
The only minor issue I had initially was the carpet brushbar kept stopping as my carpets are quite thick, but I did a little research and changed the settings so that it was suitable for my carpets and I haven't had a problem since, so just be aware that for some carpets you will need to adjust the suction power and small red toggles in the head to suit.
