I do have a greenhorn BAWB. And I don't have to worry about my perimeters and
vortex crap like you do cause I vacuum my carpet first and get all the crud out of the edges with my vacuum which has a hand tool to get the edges. Plus I don't worry about the very edge unless it's dirty. I'm putting down enough water to throurally flush the carpet anyways even on the edges. People don't walk on the edge and it only gets dirty if someone soaks them down with soap before cleaning, or the home has filtration soiling really bad. Not many homes around here use gas heaters.....all heat pumps so I don't see it very often and when I do I flush the edge by lifting the wand to get it wet then suck it out till it's gone.
Just face it Bob your 40 years of experience doesn't mean all that when it comes to
glides and modern carpet cleaning. I'm on the cutting edge.....I'd say you were......40 years ago. Don't get me wrong Bob I do like you, you seem like a good guy. But don't preach as though you know it all....cause face it you don't. Hell I don't but I'm man enough and smart enough to admit it, and I try and impliment new techniques and ideas into my business all the time. Those who think they know it all need to hang up their wands.....and that idea comes from the Great Barry Costa.
