go back to a 06 wand?
It's been so long for me I forget how much faster a 010 or 012 or more wand really is...or is it really?
Is the industry standard of 06 a cop out to make HX units function properly or is six good enough to clean most kapets :?:
Miguel,
The 06 size was the standard long before heat exchangers came into existence. When they did begin to get a foothold, the more common jet sizes actually were smaller- typically 04 and for "entry- level" systems, I've seen 02's.
One thing to look at as much as anything else, IMO, is the width of the wand. The typical "12 inch" wand is 11.5" of the ones I've taken the time to measure. So 2 jets cover an area that is half that, or about 5 inches each. 14 inch wands with 3 jets have a little less width per jet and a 14" / 4- jetter has even less per jet.
Jet proximity, or closeness to the carpet is a biggie. The reason is that so much pressure is lost over a distance. (You can prove this at any self- service car wash. You instinctively move the spray gun's nozzle closer for harder to remove residues like bugs on bumbers and windshields, etc.) So, multiple jets allow the exit point of the stream to be closer to the carpet as well. And since all wands aren't built the same with regard to jet placement and proximity, it's likely to vary from wand model to wand model as much as anything else.
Still, there's no question that high flow cleans better. Why? Because it
flushes more efficiently. And the dirtier the carpet, the more evident this is.
But then... You know that from experience.
