I'm not putting any type of cleaning down, but I can guarantee that if someone came in after me...That stuff wouldn't be in there vacuum, or filter that is for sure. Just saying.
I did bonnet type cleaning back when I was younger. The problem is you have to try and convince the customer, that the vacuum process is the most important part of there cleaning, and that what little debris that is left would be absorbed into a cotton bonnet.
Then what cleaner you used that wasn't absorbed into the cotton magic bonnet is not going to attract soils.
So after all this reeducation with why low moisture cleaning is better (today's sawdust type products vs old school chem dry methods)
I come along with a mid sized TM and pull this amount of cleaning product that was left behind from the laid off lumberjack, I can easily state my case as to why hot water extraction is just a much better choice, and with my fans placed as I clean my way out that there carpet is almost dry when I leave, the days of carpet wet for days and fear of mold and mildew smells are easily put to rest.
