I bought this as a replacement for my Dyson V6 Fluffy as I was unable to get a replacement battery for it. I had been waiting for 2 months! I was sceptical about buying another Dyson because of this?However the quality of this machine outshone the other cordless hoovers. It is so much more powerful than my previous machine and the run time is a vast improvement. If I have a criticism it is that the dust canister is still very small when you have large “hairy” dogs!! I hope that when I need to replace it, the availability of batteries will have improved. It is overall an excellent machine.
