I used to have quite a few hand and stick vacs, I think I got a lot of them because they were smaller and didn't take up as much space as uprights and canisters. My mom still has quite a few pictures of me when I was really little with carpet sweepers and stick vacs in the background. I didn't start collecting uprights until I was 4 or 5.
I used to use my Dirt Devil hand vac (like yours but two speed and North American plug+110V motor, of course)for the stairs but I normally use my Eureka SurfaceMax canister for that now. The Dirt Devil is sitting in the garage with the attachment hose attached and I only use it occasionally for cleaning up the garage.
