Me either
I have a couple grooming brushes
Also, even with high flow wands, I still do more than one pass (at least 2 passes) wet
and also do dry passes.....just feel it takes more than one pass to rinse out soils and also our own cleaning agents with the suspended soils....
Dry passes needed to also lift out remaining soils that are not getting hit some more with spray/moisture....
Amount of time per rinse stroke, depending on soil level....
also I tend to key the wand (wet pass) on the forward stroke too a lot I find....
Have you ever watched your dry passes to prove or disprove this theory of needing more than one dry pass? I have, and found we are getting all of the soil laden moisture with a single dry pass.
You can watch it with a clear view 2" tube about 6' from the wand while you are extracting. I made one that goes inline 6' from the wand.
You will be surprised at what you see. Here's what you will see; the dirty water on the first pass, and no water on a second dry pass, so the one pass is all you need.
Now this is when cleaning with a wand. For you fancy guys with all those other cleaning tools, I couldn't respond cause all I have other than wands is an old RX-20 - the one with the horizontal motor and gearbox, which still works great btw.
I even have a vac relief wand cuff with a few holes drilled in it in strategic places for using on rugs where the wand is hard to push. I also use it on some carpet that wants to lock the wand down. By using this vac relief you are overcoming the inverse relationship between lift and CFM, as it keeps the moisture flowing and does not allow heavy lock down.
Had a job today where I used it and by the time we were leaving the carpet was just damp after being cleaned with a #6 flow (each wand) and a few wet passes because it was quite soiled, just to make sure we were not leaving the carpet too wet.
We also use the vac relief cuff when we are cleaning upholstery to reduce operator fatigue and to keep from stretching the fabric. It is usually dry by the time we leave, depending on soil condition and type of fabric.
Here's a short video with 250' of hose out:
, if it's extremely soiled I may apply the trigger on the upward stroke... with the rotary, I swirl...never swing...I hate the triangle
,and tech's that say OH the customers love it
...and I always post groom in both directions leaving the carpet standing in the same direction.
