Abstract: A surface cleaning machine (10) is disclosed in the preferred form as a combination sweeping-scrubbing apparatus including a sweeping brush (18) for sweeping debris into a hopper (20) and a one piece squeegee (112) for picking up solution after four staggered, disc brushes (122). The squeegee (112) is U-shaped having a longitudinal extent greater than that of the disc brushes (122) located intermediate the legs (124) of the squeegee (112). The drive wheel (16) is located in front of the disc brushes (122), the squeegee (112) and the solution applying means (128). The squeegee (112) is raised and lowered relative to the frame (12) by an actuator (104) which pivots an L-shaped member (94), the leg (96) of which abuts against and pivots a lever (84) interconnected to the mount (62) for the squeegee (112) by a turnbuckle (88). The hopper (20) is raised and simultaneously tilted by a single cylinder (30 ) which pivots the upper arm (24) of a parallelogram including a lower arm (36).
