Japanese Patent JPH03191939

PURPOSE: To enable a main brush to wash along a wall in the same way as a side brush and prevent a washing head from a damage by forming the main brush as the washing head given a vertical force so that the washing head can operate in the position of laterally extending over the side part of a frame. CONSTITUTION: A method capable of washing the proximity of a wall without using a washing side brush is to extend a washing head 24 over one side of a machine frame, for example laterally outward by 12cm (5 inches). This means the extension of the washing head to the position shown by the brushes 26, 26'. Thus, the washing brush is located in the position close to the wall like the side brush. The lateral position of the washing head is controlled by an actuator 52 which is provided laterally below a frame of a scrubber and connected to a swing lever 54 pivotably attached to the frame of the scrubber.
