An extended-reach sewer inspection device involving a hose-driven apparatus for progressively inspecting and cleaning the inside of a pipe at remote locations. The apparatus is comprised of a hose that has a nozzle apparatus which includes rearwardly-directed non-axial orifices such nozzle is attached to a forwardly-extending axially-aligned male member that has a female proximal end connected to the hose and a distal end opposite of the hose. A skid that includes a central body with at least three pipe-engaging runners connected to it and an axially-aligned opening dimensioned to freely receive the male member in such a manner as to allow the member to rotate freely within the skid. A retainer is secured to the distal end of the male member to hold it in the central-body opening, and a video camera is affixed to the central body whereby non-rotating video images are available to assist in the inspection and cleaning of a pipe.
