A friend of mine who is not very strong swears by a Bosch Athlet model she got from Costco for about £160. It's a battery upright that's relatively light, runs for quite a long time on a charge and apparently has the Which? seal of approval.

Thanks for that.

Do you know if they use it on the stairs?
