Miele Hoovers vs any other

[stoppingat3]

Morning All, I need some advice re a new hoover (ooohh the excitement!)
DH has agreed that our Sebo has had it and, as this is the second one we've had he is up for a change.
With three children and a dog I want a really good hoover that won't balk at the job in hand.
Does anyone have any thoughts - budget up to around £300.
Many thanks

I can even do it in high heels and not get back ache, lol

Miele here, got it cos Which recommended it, like it better than flipping Henry whom used in a previous house, bumping aorund in my wake(quite tall (5 9).
