Abstract
A machine for cleaning floors is provided and more particularly a riding machine which both sweeps and scrubs the floors. The machine has a rotary drum broom near the front and three staggered disc brushes at an intermediate portion. The drum broom is rotatably carried by two arms which are pivotally mounted on a frame or body of the machine. A hopper for receiving dirt and debris from the drum broom is also moveably mounted on the arms in front of the broom. A linkage and lever mechanism is used to rotate the arms to raise and lower the broom and the hopper simultaneously when the cleaning machine is driven from one location to another. A squeegee assembly is carried by the machine behind the disc brushes for picking up the dirty solution, clean solution being first supplied to the disc brushes and to the floor. A tank for supplying clean solution and a tank for receiving dirty solution from the floor are also located on the machine above the rotary drum broom and at least one of the tanks is tiltable to the side for access to components of the machine located therebelow.
