A surface cleaning machine includes a frame, wheels for supporting the frame and a debris hopper positioned on the forward part of the frame. There is a cylindrical sweeping brush mounted on the frame for rotation about an axis transverse to machine movement. There is a drive on the frame for the sweeping brush with the sweeping brush being mounted behind the debris hopper and rotating in a direction to throw debris from a surface being cleaned forwardly toward the debris hopper. A cylindrical conveying brush, parallel to the sweeping brush, is mounted on the frame for rotation in the same direction as the sweeping brush. The same drive rotates both brushes. The conveying brush is positioned above the sweeping brush and located relative thereto to convey debris moved upwardly by the sweeping brush in an upward and forward direction toward the debris hopper. A scroll is mounted on the frame forward of both brushes and between the brushes and the debris hopper to direct the flow of debris from the brushes to the debris hopper.
