Putting a tornado in a vacuum cleaner is so 21st century.
I have one and I think they're awesome. I often had a runny nose at home and I didn't realise it was because my old vacuum cleaner wasn't very good at cleaning dust out of the carpet. When I got the Dyson the sniffles went away.
And being bagless is great for men because no real man wants to stuff about with a pussy little stupid bag. I want to go straight to the rubbish bin and just dump that crap.
I haven't seen this new ball thing though.
