An automatic floor cleaning machine includes a unitary, self-contained and propelled, power driven body mounting from front to rear in a normal cleaning direction of travel: a propulsion mechanism including drive wheels and guide wheels for dry tracking on the floor surface to be cleaned, a scrubber mechanism including a pair of rearwardly disposed, vertically articulated counter-rotating magnetically and floatably mounted brushes for wetting and cleaning such floor surface, a vacuum mechanism including a vertically and horizontally articulated quick-detachable squeegee for drying of and proper tracking on the cleaned surface, and a combined mechanical and electrical control system operatively associated with each of such propulsion, scrubber and vacuum mechanisms, for convenient actuation by a walk-behind operator to control actuation of such machine. Preferably, a sweeper mechanism is mounted on the body forwardly of the propulsion mechanism and operatively associated with such control system for advance sweeping of a debris-laden floor surface.
