i would say they are not dave ,i think bosch is the best choice as i have a mate who repairs them and he swears by bosch .if the dyson one is anything like the hoover i would not bother our hoover spent more time at dyson than it did at our house due to poor plastic it was made of, then they had the cheek to phone me and tell me i was hoovering the wrong type of dust ie decorating dust and it had clogged the filters ;) .bought a kirby and it is the nuts ,if only they made other stuff.
