"Power Washing" is far from the truth and "Steam Cleaning" is far from the truth also, which tells me you didn't know much about Hot water Extraction
And yes, it's a Chemdry false marketing tactic.
I went to a little local business expo in my county way back in my early years and I noticed chemdry had a booth there to advertise their business. So they put the VHS tape in this little tv to show their "process" of cleaning. Most of the video was all showing someone improperly cleaning carpet with a wand. they must've had that pressure turned up to 1200psi with how the water was spraying all out the side of the tool and was going so slow, allowing it to literally "Pressure wash" (not power wash) the carpet. It made me furious to see the corruption in false advertising. Look up yourself an older chemdry video
I agree, it isn't the 90's anymore. And today's truckmounts are wayyyyy better with more suction, better tools, (
glides being one of the most important), better chemistry, and better education
But keep buffing that carpet.
