Abstract: A MOTOR DRIVEN CLEANSING MACHINE HAVING AN ENDLESS BELT DRIVEN OVER A PLURALITY OF ROLLERS. ONE ROLLER FORMS THE FRONT EDGE OF A BELT-SUPPORTING MEMBER, BETWEEN TWO CONVERGING BELT-SUPPORTING SIDES, WHICH IS PIVOTABLY MOUNTED IN A FRAME. THE PIVOT AXIS IS PARALLEL WITH THE AXES OF THE ROLLERS. THE BELT-SUPPORTING MEMBER IS HELD IN A NEUTRAL POSITION BY THE TENSION OF THE BELT BUT IS PIVOTABLE IN EITHER DIRECTION WHEN THE FRONT EDGE OF THE BEL-SUPPORTING MEMBER IS PRESSED AGAINST A SURFACE TO BE CLEANSED.
