Its not sucking up the water off the carpet

Hello. Take out your recovery tank, remove the lid, and re-attach lid rolling it from the front to the back, there are two tabs on the tank that the lid has to be aligned with, you will hear it "click" when it is tight. I think this might be the trick! Let me Know if I helped. Thank you. Rene (The Vacuum Doctor) Don't forget to have your unit serviced once a year by a qualified tech!
