Outstanding on carpet, mixed results on hard floors
The V7 is my first Dyson, and I am both highly impressed and highly disappointed - if that's possible.
It has great suction and works far better than I expected on carpet. I expected it to be great on our hard floors but not have the power required to do a decent job on carpet, but I was pleasantly surprised!
But wow is it disappointing on hard floors! It picks up very small debris brilliantly, but anything bigger than dust is likely to be flicked all over the floor by its rotating motorised head.
Dyson do not make a hard floor tool for the V7, but fortunately, V8 attachments fit the V7. So if you can get your hands on the Soft Roller Head from the V8, you'll be happy.
I contacted Dyson and they were very understanding (after some firm words) and sold me a V8 Soft Roller Head for $130.
Might have been better getting the V8...
All of that said, I very rarely use my corded vacuum now, and will absolutely be buying another Dyson whenever this one meets its end!
