If no one else will admit to it, I will.
I have done that to many carpets. And I mean very many. It's funny to see some of the carpets I did 8-9 years ago with those impact marks and no one has ever complained, some even ask why I don't leave those marks any more.
When you don't know what you are doing and turn the pressure too high no your tm has blazing heat (Cobbs tm) that will happen every time with a classic 2 jet wand.
It is a high pressure with high heat that accomplishes those impact streaks. "Damage" is somewhat reversible.
A good heated RE pass, followed by some grooming will get most of it out.
Man, you are one lucky dude. My customers have always had me replace anything we damage.
