I have come back home to run my step-fathers carpet, tile, air duct, and upholstery cleaning company. He is unfortunately in hospice care, and unable to communicate with me. I have plenty of experience in carpet, tile, and upholstery, but have probably only done 15 or so duct cleaning jobs. We have a butler carpet cleaning van with the Air-Care Truckmaster system. My problem is when I am cleaning trunk lines that are 25+ ft long, the trunk line is so wide, and the hoses aren't rigid enough, and after about 15 ft, it wont go any further, as it starts to turn back the way that it came. I need something to keep it straight. Does air-care or anyone else sell some sort of poles that I can attach the hoses to so that it can travel pretty far down a straight trunk line? I hope I am explaining this well. I am having to figure all of this out all of a sudden, as my stepdad got sick so quickly and I didn't have much time to pick his brain before he unfortunately became unresponsive. Thanks for any help.
