ABSTRACT:
A sanitizing hand-manipulated vacuum cleaning apparatus embodying a floor-engaging suction head including a front squeegee and a rear abrasive pad establishing a suction chamber therebetween which is adapted to be connected to a source of sub-atmospheric pressure. The suction head is rigidly connected by a horizontal beam to a rear caster supported carriage, while an elongated handle has its lower end connected by a universal joint to the beam adjacent the rear end of the latter. The suction head, beam and carriage, by reason of their position relative to one another, and by reason of the universal joint connection to the beam, are capable of traversing the floor so that they will follow the guiding movements of the handle in a manner similar to that which obtains when the trailing absorbent strings of a conventional mop follow and are guided by manipulation of the mop handle. A pneumatic connection between the suction head and the source of sub-atmospheric pressure is provided and, if desired, a fluid connection leading from a source of a detergent fluid may be provided for floor wetting purposes exteriorly and rearwardly of the abrasive pad in the immediate vicinity of the latter.
