Best vacum for thick carpets please...

[Whereareyouscooter]

Hi,
We've recently got new carpets on the stairs, landing and bedrooms and i can't push my Dyson on it, even on the highest setting. It's great on our downstairs hard floors but I'm desperate to hoover upstairs but I just can't budge the Dyson. Even my DH finds it impossible. The carpets are incredibly thick and plush...can anyone recommend a vacum that would work please?

I have a Miele upright and that deals great with my thick carpets.

We've just brought a lovely Zanuusi upright vacuum cleaner and it works a treat on our downstairs carpet and they are really thick.

Hope this helps :-)
