I am thinking about starting a c.c. business, but there are so many claims about which method will get the best results. Does anyone have any or thoughts info on the von schrader method?(low moisture)

Great method that worked well for decades, but is now outdated and without Von Schrader coming into the 21st century will soon dissappear.

Hi Jimmy
I used several low-moisture carpet cleaning methods
enroute to discovering true love with the Challenger.
I own both a VS-1 (single-wide) as well as Mach II
(the big double wide.) I much prefer a well-designed
OP to the bulkier small VonSchrader. I also own a
24" Cimex, which I feel is a better machine for larger-sized floor areas than the big VS.
