Any question answered...

My dad has an upright dyson hoover but wants something lighter as it is too heavy for him to get up and down stairs.

Any suggestions for a vacuum cleaner that works well and is not too heavy?

If he has space to store them, maybe have a separate machine upstairs? Dysons are in a class of their own really,

Id get a dyson compact as the second machine, probably better for doing stairs and car etc too.
