ABSTRACT:
A pneumatic cleaning device attachment includes an elongated, rigid tubular section, a flexible tubular section and a rigid tubular end piece that are connected together in series. The rigid and flexible tubular sections, as well as at least a portion of the end piece, have generally commensurate inner and outer diameters. A tubular, rigid cover member, having an associated length greater than an associated length of the flexible tubular section and an associated inner diameter that is greater than the diameters of the rigid and flexible tubular sections, is slidable mounted between a first position wherein the cover member extends between the rigid tubular section and the end piece in order to maintain the flexible tubular section in a straight posture and a second position wherein the cover member extends about the rigid tubular section such that the flexible tubular member is exposed. The attachment is further provided with a handle member which is detachably mounted to the rigid tubular section. When the cover member is placed in its second position, the handle member can be used to maintain the flexible tubular section in a curved posture.
