ABSTRACT:
A carpet cleaning machine having a scrub brush, independent means for selectively delivering cleaning and rinse solutions, and vacuum means for removing the solutions and entrained dirt. A cleaning head is moved about the carpet on a pair of wheels by an attached operating handle which includes means for controlling the volume and timing of the release of the solutions. The wheels are so located, with respect to the center of gravity of the head, that the scrub brush is normally in contact with the carpet. However, in response to appropriate manipulation of the operating handle, the head is pivoted about the axis of the wheels and the scrub brush is lifted from the carpet and the vacuum nozzle brought in contact with the carpet. A pump is used to deliver rinse solution from a reservoir to the head by a flexible hose and the vacuumed waste is delivered to a remote collection chamber through a flexible hose and a portion of the operating handle. To protect the rinse solution pump, a bypass loop is provided.
