I need a small vacuum cleaner / handheld for student life?

[Cooper]

So i only live in a studio flat and i desperately need a vacuum of some sort, i have a kitchen vinyl floor and carpet. so not sure whether a handheld would do the job or not. Also im in the UK so it needs to be from a store or such like here.
Been looking around but cant really tell what i would be most efficient.

Thanks
Sorry probably should have said, being a student it has to be cheap
thanks for your reply though
