ABSTRACT:
A carpet cleaning head wherein the head 8 is fabricated of two mating elements, a shroud 12 and an inverted cup-shaped main body portion 14, wherein the main body portion incorporates radially extending vacuum scrubbers 30 and has secured thereto on the underside thereof nozzles 40 for supplying heated cleaning fluid under pressure. The cleaning head 8, including the shroud 12, rotates forming a moving seal with the carpet containing the heated pressurized cleaning fluid, exaggerating the pressure difference with the vacuum and enabling the scrubber to do a more complete cleaning operation.
