Yeah sorry about that. One of these baby's. Belongs to the shop. Very low pressure, not even a 100 psi. Cold water. Has two brush heads on it, so yes like a 175. http://www.factorycat.com/images/magnum-floor-scrubber-01.jpgWhat psi did you use? Agitated with what? 175?
Any heat when you rinsed? or just cold water flush?
