1. A floor cleaner comprising, in combination:

  • a housing including an intermediate portion with a constant rectangular horizontal cross-section along a height thereof and including an angled front face, an angled rear face and a pair of angled side faces for defining an interior space, the housing further including a bottom portion with a horizontally oriented bottom face having an area greater than that encompassed by the horizontal cross-section of the intermediate portion and a top portion mounted on a top face of the intermediate portion and extending rearwardly therefrom, the top portion having at least one cylindrical grip coupled thereto and extending rearwardly therefrom for maintaining the housing in a generally upright orientation, the front face of the intermediate portion of the housing having a first compartment formed therein for containing a cleaning solution tank, the rear face of the intermediate portion of the housing having a second compartment formed therein for containing a recovery tank;

    a scrub assembly including a cylindrical brush having a pair of vertically oriented arms rotatably coupled to opposite ends of the brush and extended upwardly therefrom for slidably coupling within a recess formed in the bottom face of the bottom portion of the housing, the scrub assembly further including a toggle switch mounted on an inboard end of the grip of the housing and having a first orientation for lowering the cylindrical brush from the associated recess such that the same may be rolled about a floor to be cleaned, the toggle switch further having a second orientation for raising the cylindrical brush within the associated recess such that the same is stored therein;

    a water sprayer mounted on the bottom face of the bottom portion of the housing in front of the cylindrical brush of the scrub assembly and connected to the cleaning solution tank for dispensing water downwardly and forwardly toward the floor at various pressures upon the actuation thereof;

    a vacuum port mounted on the bottom face of the bottom portion of the housing to the rear of the cylindrical brush of the scrub assembly and connected to the recovery tank for suctioning water from the floor upon the actuation thereof;

    a spherical ball rotatably mounted on the bottom face of the bottom portion of the housing between the vacuum port and the scrub assembly for maintaining the vacuum port a slight predetermined distance from the floor when the cylindrical brush is situated within the recess of the housing; and

    an indicator panel coupled to the inboard end of the grip for indicating a current level of fluid within the tanks and further allowing control of the pressure at which the water is dispensed by the water sprayer.
