I'm sorry I upset you that I am not black.
There was two aipaths used and the carpet was almost dry by the time i cleaned all the tools and loaded everything on truck.
To clean the crbs we remove the rod pull the brushes wipe the inside of the casing down and wash the brushes with an aux hose from the truck then vacuum the brushes and reinstall. About ten minutes to complete. Women's hair or longer hair is more of a problem with the crbs than pet hair. The pet hair as long as you clean it quick comes out rather easily.
The crbs that I have are from carpet cleaner America and are Austrian made units with 800 watt motors. It is basically a evolved Whittaker and the best version of the Whittaker style units right before they started making the newer models that interlink sells. I was selling the units for 1900 but you can get the newer style from interlink or cobbs for that matter for around 3200. For that price you will get all the goodies like the renovators, jobs wheels, large transport cradle with wheels and splatter guards.
