Unfortunately, this carpet extractor has been discontinued by the manufacturer as of 1/1/17. We will continue to carry replacement parts for this unit, but if you are looking for a new machine, we have the Maximum extractor, which has a 220 PSI pump, or we have our Supreme extractor, which has an adjustable PSI pump (0 - 500 PSI). For other options, please view our full line of box extractors.
