Hoover did for their Total System uprights as the hose would only reach up the stairs as far as that 1000 did, well, it is the same hose, but the extension was the same length as the original.
SEBO makes a HUGE extension hose for their uprights.
Kirby offer a stair cleaning stretch hose, which seems pretty pointless when you can yet it up as a “canister“ and just carry it with you.
Dyson offered a streth hose for their DC24, which I believe, even with it added to the original hose still doesn't get up the staits!
An extension hose is not really needed nowadays because if you spend more than £100 on a upright a full stair cleaning stretch hose comes as standard...Usually!
