It looks like to me a rotobrush company could easily contaminate your home. If they just came from a home that had moldy ducts, then come straight into your home blowing the previous homes mold everywhere, this could create problems. You know most of these duct cleaners that use the rotobrush dont clean the brush after using it. Just a thought.
good ol rotorbrush, a few years ago i contacted that co. about cking out there machine, every time i called i always got the secretary, never the sales guy, had to leave my # they'd call back. the guy kept callimg and e-mailing to sell me a machine. i said i'd like to come down to i think texas, and check out the facility, and check out your duct cleaning school, BEFORE, BUYING THE MACHINE AND SPENDING xxxxx'S $'S. there is no way i'm buying a xxxxx, from some dude w/o checking him out. say you make 2oo $ per job! you'll need 50-75 jobs just to break even, IMOP, unless your in a area that is high end, the only guy making $ is roto brush, again, what dope buy's a xxxxx over the phone w/o checking out the guy and co. selling it. they have a aggressive sales guy,wish i remembered his name, but has anyone been to there schooland there duct cleaning class.needless to say,i'm not big on roto brush, this is JMHO, and opinions vary.and if you do decide to buy any duct machine,crunch your payback #'S, what happens if it breaks down, where do you get parts and how much, visit someone who actually owns one and you can meet in person and actually see the real deal,what about accesseries$, this is a major investment,that requires a lot$,to build up the buisness, you'll find people would love to have there ducts clean, but they'd like them cleaned for nothing. another one of those money losing jobs. obviously, there are co. making money in duct cleaning, but it takes one heck of a marketing commitment$,and isn't as easy as these guys make it sound. again this is my JMHO< do your do diligence, and buy what ever with your EYES OPEN!
I have also heard STAY AWAY FROM ROTOBRUSH.
We bought a negative air pressure duct cleaning machine for about the same price as a high end rotobrush and the owner of the company even flew out to oregon(on our dime of course) to train us on the equipment.

Negative air pressure is the only way to go. Another downside to the rotobrush is it only cleans up to 15 feet of ductwork if I remember correctly. Our negative air system is a 3 part process with 15 foot brush and hoses that clean everything else.
With duct cleaning it is hard to overcome the customer.. but I saw it from others for $99... we charge 5 times that and usually get it because we spend 8 hours per duct cleaning to get them perfect. 1.5 years an 0 call backs.
Its easy to make money for $79... you upsell every job another $800 or more and bully customers. I had a customer with a nice honeywell F300 EAC and the duct cleaner convinced her it was better to buy his $250 filter than use the F300(it was a standard MERV8 filter i buy for less than 1/10th of that price) This was the $99 special at the time out of the newspaper. She told me they left with over $800 in additions, and it was pretty close to $900... needless to say we still had to clean her ducts they were so filthy, no work was done, just $900 and 2 hours labor for a filter.
Man am I glad I passed on rotobrush. Almost got suckered into it. I only had a couple customers ask me about duct cleaning so I figured it would not benefit me.
not the 60-80 yr old ones w joist panning and several inches of crap in the panning...
only thing the roto duster did was repeatidly clog..and cover the home w
a fine layer of dust...
a total piece of crap imo
I make good money from my machine. If you can't sell the duct cleaning for the price youre trying to....it sounds like the problem is YOU
