Abstract
A water extraction cleaning machine has a suction nozzle assembly with two suction nozzle openings incorporated. The suction nozzle openings are preferably positioned one on each side of the cleaning solution spray nozzles so that the cleaning machine can be used for simultaneous application and removal of cleaning fluid regardless of whether the user is pushing or pulling the cleaning machine. In another aspect, a plate member is slidably mounted to the bottom of the suction nozzle assembly. The plate member has a pair of suction nozzle openings which are spaced to seal one of the two suction nozzles of the suction nozzle assembly depending upon the direction of travel of the suction nozzle assembly.
