1. A floor treatment apparatus comprising:

  • a multi-part enclosure comprising a primary enclosure, a front enclosure portion, and a rear enclosure portion, the multi-part enclosure having a front surface, a rear surface, an upper surface, a lower surface, a left surface, and a right surface;

    a first wheel operably interconnected to the lower surface adjacent to the left surface and located closer to the rear surface than the front surface;

    a second wheel operably interconnected to the lower surface adjacent the right surface and located closer to the rear surface than the front surface;

    a platform located closer to the lower surface than the upper surface and substantially between at least a portion of the right surface and at least a portion of the left surface, and extending from a portion of the rear surface, wherein a portion of the platform is positioned substantially adjacent to an axis extending between a center of the first wheel and a center of the second wheel;

    a floor treatment assembly operably connected to the lower surface of the enclosure;

    a power source positioned substantially within the multi-part enclosure;

    an electric monowheel drive motor associated with the power source;

    a third wheel associated with the electric monowheel drive motor and operably connected adjacent the lower surface of the enclosure;

    a steering mechanism associated with the third wheel;

    a steering wheel operably interconnected by a shaft to the steering mechanism wherein the steering wheel is associated with the front enclosure portion, which is capable of selective rotation relative to the primary enclosure about a first axis that is parallel to an axis extending between a center of the first wheel and a center of the second wheel, the front enclosure portion including a control panel, and wherein the steering wheel maintains a position relative to the front enclosure portion when the front enclosure portion is rotated away from the primary enclosure; and

    wherein the rear enclosure portion is capable of selective rotation about a second axis parallel to the axis extending between the center of the first wheel and the center of the second wheel.
