Since around here carpets are so loose you don't dare operate a rotary machine on them I have found bumping them up and many times trimming them is easier and more profitable.
Normaly we treat the lines, run a brush on a stick to scrub and run the crevice wand on them if they are wood baseboards, never on fiber baseboards. Even then carpet is so loose around here we'd end up pulling some carpet off tack making it worse. Often the carpet wouldn't be on tack.
So we use a homemade kneeless stretcher from a harbor freight stretcher with a homemade wooden claw with nails that fits into the small pole/rod. A harbor freight stretcher is "all things cheap" I know but it's the only tool I could find to stretch closets, 3' hallways and stretching stair widths.
I made some extra hundred dollar bills last Wednesday on a cleaning job doing this, hadn't done it in over 5-6 months, did about 6 walls. It's Sunday and I'm still in pain. Wrists are shot and my back, oh my back. My female tech just got a new knee so she won't get down on the rug. It's time to get off the truck and put a young buck in there.
Recovery times are getting longer and longer. Facing old age is not fun especially when you enjoy what you do.
Visited an old carpet cleaner I know that frequents this campground Friday, he's 64, looks bad, does about 4 hobs a month now he says. Caught him and his old lady doing puzzles through the window of his RV. I don't like puzzles! It can't end this way!
