We really had no idea just how much we needed this crazy cleaning machine but once we saw how much grime came out of a carpet we thought was clean we were shocked. We moved onto the dining room chairs and in no time they looked and smelled wonderful. Then we braced for the big project. A couch and love seat we have had for 7 years. We vacuumed, spot cleaned and occasionally sprayed some fabreeze on them but that was all we could do until now. OMG! This machine is an investment in your furniture!
