RS:
While I don't have a photo to offer, I can tell you what I use for stairs.
I have an American Electrolux 1205 from 1973, with an Electrolux Sidekick, a miniature power nozzle introduced some years later. The Sidekick attaches directly to the end of the electrified hose.
This combination means that stair carpet can be vacuumed and brushed in one go, very quickly. I find it very convenient.
The Sidekick attaches as quickly and easily as the dusting brush or any other above-the-floor tool. It's also great for vacuuming up pet hair on upholstered furniture; even the messiest divan or chair can be cleaned in one pass. The Sidekick's brush roll is nicely aggressive, so it really fluffs and grooms carpet.
