Well are they?
I am not sure Dyson was in business when we bought our last hoover.
How do you do the stairs with one of those upright fellas?
What about the things that look like Dysons but aren't? There was a purple Vax effort in Tesco today.

Hello!
We've noticed this thread is quite old and some of the product recommendations are a little out of date. After weeks of trawling the Talk boards, talking to parents and researching bestsellers, we put the top vacuum cleaners on the market through their paces to find the best vacuum cleaner for most families.
Hope this helps!
