Well if you're gonna sic the dogs, I mean pigs on them, I hear comments all day long about how good the equipment is, chemicals, etc but if you don't know how to use them, it means nothing. When I first started in my own business, I had a G.H. Wood portable and a powerbrush. Took my time and did beautiful work with it. Scrubbed the stairs by hand and rinsed. Took work away from all the big guys with their tm's. Yes, it's easier with a tm but only if you know what you're doing. I wouldn't trade my tm for a portable but if that's all I had, I can still knock you're socks off.
