Help me choose a vacuum - want cordless, quiet and lightweight

[VioVee]

My house has Karndean downstairs and carpets upstairs. 2 flights of stairs.
I'm older and want something easy to use. There's just me and the cat. What would you suggest?

we have this. It’s lightweight, quiet and can handle a cat, a dog and three long haired residents in a three storey townhouse.

If you have a big budget, one of the newest Dysons. I loathe Dyson but I have to admit, the £800+ cordless vacs are pretty good.

I have the cordless shark. It was about £200. Very light.

I always recommend the Henry/Hetty Quick however I am catless so I don't know whether it's good for that but it certainly copes with my long hair.
