Dry strokes are super needed with his flood the carpet teqnique, using the rinse to continue to clean with each wet pass over and over on the same stroke path.
In reality he needed many dry strokes and a post pad would of helped greatly.
But who knows, many cleaners don't do either and get away with it on the regular.
In a place like Arizona or albequerque I could see getting away with that every day with the aid of an airmover blowing for 15 minutes or so after the job is complete as the carpet would dry super quickly.
Everything looks pretty new and way too much detergent coming through the wand. Needs dry strokes and on the trigger way too much, and I try to never stand on cleaned carpet while wanding like he is. You track from dirty pre=treated carpet to clean you might get a customer calling you back saying they see footprints. I wonder what his potion is because it still was eating that dirt up pretty good. One last thing I have a feeling his psi was 600 or higher the way the steam was shooting back at him.
He's definitely going to leave railroad tracks. His pressures so high he's misting the air. Don't believe that was steam. He never did a dry stroke at all. Funny thing is the person may have called someone else to fix it and they think it dried fine.
That cleaners says he has been cleaning carpets for 17 years!
Another example of Years on the Job doesn't equal years of Experience.
When some people say: "I've been doing this for X amount of years" I ask--- "How many years have you been doing is Correctly!? when Asked I say: "I started in 1989 but didn't start to do it correctly until 1995."
Our tools and Chems have changed over the years and our methods or techniques should change with them IF needed. That's why its important to never stop learning about our profession.
If your machine is capable of recovering higher pressure and flow then there is less of an issue of output. With the exception of distorting at extreme pressure.
