1. A combination vacuum cleaner and liquid extractor foot for cleaning a surface comprising:

  • a housing having a front edge, a rear edge opposite the front edge and a bottom surface extending between the front and rear edges;

    forward and rear wheels mounted to the housing adjacent the front and rear edges, respectively;

    a first suction opening formed in the housing bottom surface;

    a second suction opening formed in the housing bottom surface a spaced distance rearwardly of the first suction opening;

    a vacuum source;

    an outlet suction conduit mounted to the housing between the forward and rear wheels so that an operator can apply downward force to the housing by applying downward force to the outlet conduit;

    a connecting conduit between the first and second suction openings and the outlet suction conduit; and

    a diverter valve mounted in the connecting conduit, the diverter valve selectively connecting one of the first and second suction openings and the outlet suction conduit while at the same time selectively occupying a portion of the connecting conduit thereby at least partially blocking suction communication between the other of the first and second suction openings and the outlet suction conduit, and vice versa.
