ABSTRACT:
A dual mode carpet cleaning method is capable of being used in both a deep cleaning mode and a fast drying surface cleaning mode. The method utilizes a carpet cleaning apparatus that provides selective communication with different sets of cleaning jets. One set of cleaning jets is operated to deliver a first cleaning solution that penetrates deeply into a carpet in the deep cleaning mode. A second set of cleaning jets is operated to deliver a lower flow rate of a second cleaning solution that does not penetrate as deeply into the carpet and dries quickly. The method involves manually operating a valve on the apparatus to selectively communicate a source of cleaning fluid of the apparatus with one of the first set of cleaning jets and the second set of cleaning jets, and discharging the cleaning liquid from the selected one of the first set of cleaning jets and second set of cleaning jets onto a carpet to be cleaned.
