If you do go pro, get a good one from Angie's List or off Yelp. Lots of bad CC's out there. Don't go for some cat that says spotting is extra, blah, blah. A good pro CC'er cleans regardless of what needs to be done.

Yes, they should move furniture as necessary.

A good friend of mine went into the CC business following his dad. He tells me there is enough soap residue in most carpets that have been cleaned even just once that he usually fires up the steam and just sucks out the old residue and cleaning at the same time. I know when he gets done the carpet is softer.

If he does use his soap, he goes back with a clear hot (very hot) water rinse. I know that's what the machine is supposed to do to begin with, but this guy gets things done right.
