Unplug the machine, recline so the machine is flat on the floor. Turn it over and unscrew the seven (7) scews with a Phillips head screwdriver (magnetic is preferred) (See picture below). Once all the screws are out, turn the machine back over, with the machine still reclined, and lift the plate straight up and set aside (see picture below). Grasp the brush at both ends and lift to remove. Clean off any debris, hair, or string. If the brush appears worn or the ends seem jammed, the brush will need to be replaced.
