Lol I've done that once. The jets on my wand clogged. So i finished up with detail tool. After thought was it probably would of been faster to take jets out and clean them being it had to be done regardless. But no way I’d film it as a how to or this is how its done video lol.
Met a cleaner one time had an old pto where there was a hole cut out in the floor of the van with a belt running thru around the driveline his throttle control was a brick on the gas pedal. He was cleaning whole jobs with a 4 inch stair tool on his hands and knees.... i gave him a 12 inch scrub wand to help him out
