Most risers do not need the full steam extravaganza, as dust & sand do not migrate upwards. Some get front of the shoes marks and rarely some dirt (and then they need it.) Otherwise, just misting and good vacuuming is all that's needed.
However, from these videos it seems like the part that needs most attention (the stairs' nose) does not get as much attention. In my experience, being able to continue the wet cleaning motion down, following the nose curve (which physically is not possible with these long tools,) is what makes the best visible improvement.
Where I am, there's lots of curvy, tight and narrow stairs. I'd love to see the circus performance on these.
To each his own.
I totally agree that from recovery standpoint, there's no need for 2", plenty of suck with these stairs tool. Unless you really do not want to deal with a whip and are willing to deal with a much less flexible and more cumbersome hose that eventually, sooner or later I guarantee, will cause some damage. Unless, of course, you're a faux macho like Desky- the no Fels hack.
