Wasn't sure what to expect but the reviews looked good so I booked appt. So glad I did. Gentleman called me 15mins before to let me know he was on his way, and arrived on time. Spent a good 45mins treating and cleaning the couch, and has since dried and looks like new. The portable unit worked very well, and I asked to see how much dirt was removed and was surprised how good of a job he did. Thanks Chem Dry!
