ABSTRACT:
An improved suction head for a surface vacuum cleaning apparatus which includes a glide shoe having slots on the bottom thereof adjacent to the leading and trailing edges of the shoe, a vacuum conduit in fluid communication with the glide shoe slots, a nozzle positioned within the interior of the head and between the leading and trailing glide shoe slots to spray cleaning fluid onto a soiled surface, and means for permitting air to continuously flow to the soiled surface through the interior of the suction head when the glide shoe is in contact with the soiled surface whereby air flows continuously into the slots from both the interior and the exterior of the head during operation so as to assure that substantially all of the cleaning fluid sprayed is drawn into the glide shoe slots.
