ABSTRACT OF THE DISCLOSURE An automatic self-propelled carpet cleaning machine comprises a body movably mounted by a drive wheel. The body is powered by a drive motor which may be selectively connectable either to an AC power source located separately from the body or to a DC power source contained in the body. In addition, the body includes a first storage chamber for receiving fresh cleaning solution therein and a second storage chamber for receiving spent cleaning solution there- in. The first and second storage chambers are provided by a flexible membrane which divides an enclosed cavity into two parts. A scrubbing means is also carried by the body in back of the drive wheel on the body. The scrubbing means includes means for applying the fresh cleaning solution to the carpet, means for agitating the carpet fibers contacted by the cleaning solution to remove foreign material there- from, and means for removing the spent cleaning solution from the carpet and placing that solution in the second storage chamber.
