1. A suction head for a vacuum cleaner, comprising:

  • a body forming;

    a suction passage connectible with a suction source, andat least one downwardly open suction port communicating with said suction passage for sucking debris upwardly into said suction port from a floor as the suction head is moved in forward and rearward directions across the floor;

    a rag roll device mounted on said body for rotation about an axis oriented transversely of said forward and rearward directions, said rag roll device being arranged to contact the floor to be subjected to a rotation-inducing force during movement of the suction head; and

    a rotation regulating mechanism mounted on said body and operably connected to said rag roll device for holding said rag roll device against rotation when said rag roll device is moved across the floor in one of said forward and rearward directions, so that said rag roll device performs a wiping action against the floor, and for automatically releasing said rag roll device for rotation about said axis in response to movement of said rag roll device across the floor in the other of said forward and rearward directions, so that different portions of said outer periphery of said rag roll device assume a floor-contacting position when said rag roll device is moved across the floor in said other direction.
