Just looking for some feedback on your thoughts about shampooing carpets, in the old days it was very popular, however the shampoo was left in the carpet and nothing was extracted out and the quaility of the chems back then is certainly not as good as it is today--Todays carpet shampoos are much better and don't allow for rapid resoiling as they did years ago--So the question is--If one were to use a 175 rotary with solution tank mounted on it and using of course carpet brush on it-first shampooed the carpet, but then used an extractor to rinse and extract every thing out?? what are your thoughts on this method--back in the 90's and for 7 years i had my own carpet cleaning business and this is what i did--shampooed then followed with extractor and sucked it all out--It worked great, never came across a carpet i couldn't make look great no matter how dirty and nasty it was, always had repeat business and referals and stayed busy all the time. Well i'm back in the business and pretty much do it like most everybody else--pre vac--pre-treat-agitate-dwell time, rinse & extract-- doing it this way works fine and results are very good, I have an mytee M5--rotova 360i with carpet brush head and standard head that comes with it, also have a 175 rotary with solution tank mounted on it along with carpet brush for it--However, I think going back to the way i used to do it with todays better more advanced chems I can do a much better job--any and all feed back anyone can give would be great weather it be good or bad and thanks in advance to all who replay
