Unless of course you dab into 36 flow!
No wait......
How about 48?
Don't know about the rest of the country (except Texas) but here in California, unless scuffed, the riser does not get much dirt. Kind of funny, but gravitation seem not to allow the sand and dust to jump vertically and embed themselves deep into the riser's pile. But who knows, that may be a California thingie.
So super heavy flushing of the riser seem kind of......... well ...........silly.
The short PMF 6" stair tool seem to be the best. Yes, you'll be on your knees, however it is a much less awkward position than some of you do with the wand. It is flexible and allows you to reach everywhere. Particularly working horizontally and deep into the nose, which is the trouble area of all stairs. Just like PMF's jet in the vacuum line upholstery tool, it is simple, not very expensive and achieves
superior cleaning results.
Unfortunately, it's not as sexy.
Just send the extra money you saved to Harper. He'll advise you what to do with it next :shock:
Harper, the ball is in your court.
