I used this company after purchasing a Groupon. The descriptions included "deep cleaning" and noted starting at the base of the carpet fibers to lift everything away. Here were my issues:
1) Though I have only about 1,000 square feet of carpet, my house is about 2,300 square feet. When they arrived, they told me it was too large for the deal I'd purchased. I pointed out that the amount of carpet to be cleaned was far less than the deal. It didn't matter; they charged me an additional $85.
2) I was informed that the Groupon deal only covered "surface cleaning" despite the description of "deep cleaning" on Groupon. If I wanted deep cleaning, however, they could do it for an additional $200.
I would have cancelled the entire service except that I had movers on hold until the carpet was cleaned. I absolutely do not recommend this company if for no other reason that misrepresentation of services. Within a month of the cleaning, all spots and stains had resurfaced.
