you can always turn the heat down, we dont run those high temps on jobs that dont need it.
but personally even medium soil cleans much better at 200 than 160, by better I mean more efficiently
I cant even begin to tell you how many customers "holy shit" at the effect of the steam, "the last guy definitely didnt have that"
its a show sure, I can clean fine a with rug dr or a bissel.. I can also clean fine with a regular van but we choose this equipment and big box trucks because it has a very positive impact on customers.
we push these things heavily in our marketing and its apart of our brand, it sets us apart from the 200+ other guys in our city running a chevy express, its part why we can demand .50 cents per square foot.
other guys are charging $200 for what we do for $450, yet our customers are our biggest advertising and theirs cant even remember their name, and they keep running cheap deals like the rest of the pack.
Dont under estimate the impact you make on every job, every little thing counts even if your customers dont actually verbally tell you. Having every thing you bring in the house branded and clean looking all showing your labels will set you apart big time.
