This video shows a company using a wand to extract. We did in the beginning of our company use one i think ever carpet cleaning company has at one point and some still use it as their main tool. I have found with my 4 prior steps and my rotovac 360i, we get the deepest clean around. Ask any of our customers or if you want to see for yourself give us a call. We are eager to show you how clean your carpets and even tile can look when we are finished. Hope to hear from you soon.
