Abstract
A camera, as for example a TV camera, is associated with a hydraulic jet nozzle unit whereby delivery of water under pressure to the jet nozzle unit causes rearwardly-directed jets of water to advance the camera and jet unit along a sewer, with the structure being retracted along the sewer by suitable means, such as rewinding a hose which supplies water under pressure to the jet nozzle unit.
