I started designing the hose reel kit about 6 months ago, it has been going thru changes and real life uses up to the point that I have no more refinements to make. I have 10 of these kits boxed and ready. Carpet cleaners are a hard breed to market to, we are all doing the best that we can but have different standards. I just started marketing these on e-bay as of a couple of days ago. I am not picking on people using portables but in my experience over the last 24 years of carpet cleaning. I stay busy with no advertising, I only advertised for the first 2 years. Using a truck mount over a portable gave me the edge to do a better job. Using a portable for a backup in my business would not work. Calling my customers and telling them I will not compromise, it is the truck mount or nothing, has given me the reputation that I have. All carpet stores in my area recommend me. I only had the portable available because I used to do upholstery cleaning and it made no sense to me to run a huge truck mount when a portable could do just as well on upholstery. I no longer do anything besides carpet and I stay totally busy. It doesn't make sense to do a sofa for 75 an hour when I can do 200 to 250 an hour doing carpet, at least that is how it works in our area. The carpet that I cleaned with the portable was a 12 by 15 room, full of human pee and soap from the janitor trying to get it out himself. The portable filled the lines with foam right away and my little portable could barely pick up any water at all, even with defoamer. I had to finish the job so I put my little 3 inch upholstery tool on and got on my hands and knees to finish the job, never again. There is just not enough power and air movement with a portable to make it work on carpet , in my opinion. My truck mount has a 25 hp motor on it , my portable has maybe 1/2 hp motor on it or less. How can you compare? Sorry for getting carried away.
