ABSTRACT:
A cleaning device for cleaning wall rugs and the like is disclosed. It comprises a cleaning head, a rigid tube and means for connecting the cleaning head to the rigid tube to permit relative movement between the head and the rigid tube. The head has a fluid discharge open end enclosure for applying cleaning fluid to a rug surface throughout a first area and an annular opening substantially surrounding the open end of the discharge enclosure through which a vacuum is applied to the rug surface throughout a second area. The spent cleaning solution passes through the annular opening to a vacuum source regardless of direction of movement of the cleaning head while it is in contact with the rug surface to be cleaned.
