John Buxton,
Your comment is a fair one. I ran truck mounts for 25 years and now I run portables. I have nothing against truck mounts, I love the power. I have a much smaller but defined clientele and choose to work with portables due to the location and access to most of the homes I work in.
For all of my cleaning career, little over 33 years, I have always used Cimex equipment, residential, commercial, area rugs, always used it for agitation. It allows a great flexibility to add different combinations of cleaning solutions to go along with pre-spray. Then when it is extracted, all I am really doing is flushing or rinsing the carpet. I put this clip on to show it with brushes because I think many do not know or understand brushes and Cimex go together. Just my observations.
For the last 25 years or so I have been pile lifting or brushing and then vacuuming the carpet afterward before ever putting any cleaning solution on the carpet - rugs or what ever was being worked on. It all follows the cleaning standards and works well for me. Besides doing a very good job of cleaning, the cosmetics of pile lifting in the dry and wet stages of cleaning really help appearance.
Nothing was meant to suggest any extractor over another, just sharing an operation of a Cimex with brushes.
Take care,
SA
