I do NOT write reviews of products I purchase online. Until now! My wife was ready to toss our wall to wall carpet, then found this machine. The cost seemed high but it was cheaper than new carpet. After two runs with the Big Green, we now have "new carpets". The water from both runs was almost mud! Yes, this machine sucks! As it should. Don't waste money, as I did, on cheaper lighter machines that don't do the job.
