An anyone recommend a good carpet cleaning machine....?

Go to www.iicrc.org to locate a professional, trained, insured, certified pro. If they use a Dri Master, RX20, or a Roto Vac 360, cleaning machines with rotating heads, the better. They all out work a man or lady on a wand by about 500 times. The Rx has a 3 foot see through hose so you can actually see the dirty water heading out to the trucks holding tank.
