Abstract
A floor cleaning apparatus, particularly adapted to clean carpet, is disclosed. A rotatably mounted brush extends in a transverse direction substantially parallel to the floor. The apparatus has front and back ends with a plurality of foam-producing nozzles mounted to the rear of the brush, the nozzles being positioned to spray foam into the brush, so that rotation of the brush causes the foam to be brushed into the floor. Vacuum means are also included which have a downwardly directed intake extending transversely across the apparatus, the intake being positioned forward of the brush so that rearward movement of the apparatus causes the vacuum means to remove foam and released dirt from the floor.
