ABSTRACT:
A surface maintenance machine has a cleaning system which includes a rotatable brush and a mechanism for raising and lowering it, and a drive for propelling the machine in forward and reverse directions. There is a visual control screen for use by the operator which has a plurality of display sectors, at least some of which display multiple information icons. There are a plurality of buttons for use by the operator, at least some of which are each associated with a specific display sector. A central processing unit is connected to the visual control screen, the control buttons, the drive for the brush, and the drive for propelling the machine. There are sensors connected to the central processing unit and positioned on the machine to determine operating conditions in the cleaning system and the propelling system. A microprocessor evaluates instructions received from operation of the control buttons and the operating conditions determined by the sensors, and then issues commands to the cleaning system for operating the brush, its drive, the mechanism for raising and lowering the brush, the propulsion system and other appropriate systems.
