Carpet Steam Cleaners in Twin Cities

Polite, prompt, only use water and no soap or other chemicals.

We were actually home when they cleaned our carpets, but we have a good section that his hardwood so we had someplace else to go. I don't know that you'd have to keep baby out of the house, though it is noisy. You won't want to be doing a lot of walking on the carpets for a few hours until they start to dry.

Contrary to the other two posters, I did NOT have good luck with Zerorez. Maybe it depends on the kind of cleaning you need. I had pet stains from my very elderly dog. Despite two attempts, Zerorez was not able to get them out. The people who came to the house and the customer service people were all very nice and tried to be helpful, but I still had stains on my carpet. I had to go back to my usual carpet cleaners (who do use chemicals) and they were able to get out the stains (and at a much lower price).

I like Green Clean. Their website is www.greencleancare.com When we used them, I had questions and they were helpful, friendly, and prompt.

I second the Zerorez suggestion.
