Abstract

A particular wide-area vacuum/squeegee-head floor cleaning tool, in accordance with the principles of the invention, includes: an elongated frame including a top, a front, a back, a first end, a second end, and a soil uptake opening positioned between the first and second ends; at least one squeegee blade at the front and extending between the first and second ends; at least one squeegee blade at the back and extending between the first and second ends; a first wheel at the first end; a second wheel at the second end; and a third wheel at the soil uptake opening. The first, second, and third wheels are constructed and arranged to support the elongated frame above a floor surface when the squeegee blades at the front and back are in contact with the floor surface in a deflected orientation and vacuum suction is applied to the floor cleaning tool by the vacuum source.
