Customer doesn't remember the name of the previous cleaner, but a RE was not used and "zebra stripes" were also left by that cleaning. I didn't notice stripes before I cleaned, but a lot of soap in the carpet. His daughter's house is where I used 900 psi to get old soap out. Possibly same previous cleaner.Who or what cleaned it last time?
You do impressive work Russ!Rotary extraction has helped give me confidence that someone else would have a very hard time showing us up.
The soap could be what screwed you. While I've never seen it done with a rotary, I've seen a wand streak due to soap residue. I'm not sure if it foams and don't allow full spray pattern but something goes on there.
The spray goes in but the soap foams and prevents correct extraction leaving behind most of the dirt.

Gene's and Rick's ideas seem plausible. What rinse would work to prevent foaming? I used End Zone.
Joe, how do you stagger the plastic shoes? Together with steel? Lisa once told me worn/scratched plastic shoes can be more aggressive than steel shoes, and that is my experience.
Lisa, are GreenGlides for the Hoss on the horizon?
Russ: I got the Hoss about a year ago. Before the Hoss, I wore out a new RX20. I Have some experience with rotaries, but I'm always eager to learn new tricks.
Reread my original post. I increased pressure from 300 to 900 in 100 psi increments in an experiment to flush another carpet that had been left impacted to the base with soap. This was on another job and it worked well.
On open areas, I usually make three wet parallel passes, tilt the head to clear solution, then trace the three wet passes with dry passes. Three passes is the maximum width for me to comfortably reach across with the machine.
Went back to the job with "zebra stripes" today. Yup, faint black stripes along the path of the Hoss. Customer said he cleaned it with his home unit, and another cleaner cleaned it since. The other cleaner also left stripes with his wand. Problem was lots of soap residue from one or both sources.
Vacuumed, sprinkled crystal defomer per Mark's suggestion, sprayed Zone Perfect, scrubbed with Brute and Tu-way pad, extracted with Greenhorn and End Zone, dried with Airpaths. Looked good when I left.
The key seems to be defoamer. Is it possible to add defoamer to prespray or rinse instead of sprinkling it on and raking it in?
Thanks to everyone, even Russ, and especially Mark and Gene who, I think, had the key idea. Next time I Hoss, (probably tomorrow morning)'I'm going to try Jim's pattern.

Foam Defense is a great defoamer to be added to your prespray. It actually boosts cleaning as well.
Foam Defense can be added to almost any prespray for carpet, tile & grout or whatever. Some encap presprays could have compatibility issues.
However, not many folks bought the Foam Defense. Not currently being made. Some distributors still have the product on their shelves.
If I remember correctly we used to use alcohol in the rinse to knock down foam. now we just sprinkle the powder defoamer before hand. Easier
