Hello everybody. I'm about to start my carpet cleaning business with a new portable Nautilus MX3-500H. I was about to buy a used truck mount but read in here how risky it can be to buy a used one. A new one is out of my budget at the time so, I thought I would go for a portable that in my opinion, is a very good one. I know that there is no portable as good as a truck mount, but as stated above a tm is out of my budget. I'm a bit nervous because I read on another posting that customers tend to look down on porties. I guess my question is, do any of you here run your business with a portable only in residential and commercial? If so, what is your experience with them and how much money more or less can one expect to make doing it part time to start? Your feedback is much appreciated. Thank you.
