Yeah the Miele brand is incredible and IMO the best.
We have cats and had various hoovers including Mr Henry.
However, the Miele is by far the best we have had so far, makes the carpet look brand new each time used and it is quicker to hoover with as well.
Well worth looking to purchase with the Miele Turbobrush accessory (comes standard with Cat and Dog model) as this helps to reduce any effort hoovering, also for me this hoover is not overly loud compared to others and does not sound like it is straining.
The model we went with was the Cat and Dog S6220.
From now one will also look at Miele's kitchen appliances - currently use AEG.

Don't worry of unsure which turbobrush as most retailers will have the correct accessory shown for the hoover model you are interested in.
