Just an idea
I don't know what you paid for this, but I'm sure you got a good deal. I wonder
if this machine could be used as a pre-scrubber on heavily soiled carpets, like shag
rugs, to be followed up with a steam extractor to finish the job. I say this because I
offered to clean a rental for a friend whose unit had badly soiled shags and I tried
everything I knew and at the end of the day it was a bust. He replaced them with new
plush pile. If I had your machine I would have considered trying to use it just to see
the results. Do you think the bristles are too long for this to work?
