Some guys have posted one pass, no dry pass, and the carpet is dry. Well, how fast is the wand moving, what overlap etc etc. That's the point of this thread.
Now, what are the best techniques in using it?
Ron, I'll preface by saying we've never had excessive dry times
even in the "olden days" before all the pimp mods that are popular with many of us now..
ASSuming all things our equal, like humity levels and air movement,
I've determined several factors are at play in dry times.
*NOTE* when I say "dry times", I'm mean "fo-reel" dry.
NOT the bUlloney "dry" deffinition that most of these apple knockers use.
Which is anywhere from "no water DRIPPING off their hand when touched" to "slightly damp" in reality
but i digress...
First, is the amount of pre-spray used/needed.
It's my observation that that is the biggest factor in fast or slower dry times.
There's a thing called "saturation"
Once a fiber is saturated with pre-spray, I don't care if a sOOper sUcker is so powerful it could pull the nails out of the tack strip.
Heavy pre-spray lenghtens dry times
Next is wand technique.
If PSI, lift and airflow are right, it's been my observation that speed of stroke doesn't make a lot of difference in dry times.
A slow stroke really leaves a carpet no wetter than a fast one.*
Yes, you're using more water w/slow stroke, but the vac slot is also over the fiber longer.
*The exception would be with the jamokes that blow WAY too much PSI straight down into the backing.
I cringe when I hear someone that's "suposed" to know something about CCing suggest 600 to 650 psi with a 06 flow 2 jet wand. :roll:
It's no wonder to "me" why they no longer clean carpets and are now in the manufacturing/juice sales end of the biz
Lastly, air flow at the wand carpet interface can make a tremendous difference.
If a TM has so much lift, the wand sticks to carpet, guess what? you ain't moving any water!
I figure that's the biggest reason so many claim such dramatic improvements in dry times when they first stick on a quality
glide like GreenTeam's
That "wand lock" is also a major reason why so many have problems with com carpet, imHo
