A floor surface maintenance vehicle, and methods of using a floor surface maintenance vehicle, the vehicle including a frame, a plurality of wheels, a cleaning component extending from an underside of the frame, a steering wheel having a central aperture and rotatable about a central axis, and a steering wheel hub located within the central aperture of the steering wheel and having a panel, wherein the panel is stationary relative to the central axis. Buttons are provided on the panel, including a first button that is C-shaped and extends around a portion of a periphery of the panel. The C-shaped button may be used to control frequently used functions such as cleaning functions or operation of a horn, for example.
