It's the angle of the jets and spray bar that is preventing the flowering and crop circles....
I have tried to flower and cause damage on a number of carpets (owned by me or family

) hooked up to my
Butler High Heat at 1000 psi at the truck....
Have had it sitting and burning in one spot for 5 seconds....10 seconds.....I have not been able to cause damage....
The unit is easy to push and pull while cleaning...doesn't get stuck in one spot....even if did....which it won't.....no problems....
Anything that is left behind I have been able to groom out....
As far as flow with the 1000 psi....it is putting out the same flow as my regular 12 flow Zipper at 500 psi.....I have tested it....
