ABSTRACT:
An improved drivable automatic floor cleaning machine includes a carriage supporting a fresh liquid compartment, a dirty liquid compartment, a cleaning rotor, a travel roller pair, and a rearward suction nozzle. The improvements include an adjustable machine frame with a depending protective curtain surrounding the periphery of the rotor remote from the suction nozzle, the machine frame being adjustable, preferably automatically, to accommodate rotors of different diameters, and to confine the cleaning liquid beneath the machine for improved efficiency and range of operation using either battery or rectifier power.
