was just wondering, what people thought, that unit is quite small for the fortune they want. i think they are crazy for wanting so much for couple pcs of plastic and some metal.
Scott,it is just another way of cleaning ducts,not nearly as effective as neg. air,but a process nonetheless.I used a gas powered portable,worked almost as good ,but a fraction of the cost of a truckmount.
Greenie named it correctly "Rotojunk". I had to buy one for one job that wouldnt allow hoses on the floor (retirement home). These were small apartments and it did better than nothing. I used to use it on residential in addition to a large truckmounted vacuum but only in the supply runs which are small and round. Never would I ever use it as a stand alone cleaning unit. The only thing worse would be the carpet cleaning / duct cleaning crap. Plus the cable broke and Rotoshit promised me a replacement but never delivered even after I returned the broken one to them.
Buy a gas powered portable, good compressor, and you'll do a good job for a minimum investment. Jobs were $300+.
