1. A device for cleaning the internal surface of a pipe having a main pipe axis, the device comprising:
a cage having a front end and an opposing rear end;
a tubular housing disposed within the cage and extending between a front end and an opposing rear end;
a plurality of tubular conduits each having a front end and an opposing rear end and each being disposed within the cage so as to be laterally spaced apart from the housing, each of the plurality of tubular conduits having an encircling conduit wall with an outside face extending between the front end and the rear end thereof, an inlet being disposed on each tubular conduit to receive a pressurized gas;
a plurality of nozzles being spaced apart along the outside face of each tubular conduit so as to be in fluid communication with the tubular conduit, each of the plurality of nozzles being sloped toward the rear end of the cage so as to be disposed at an angle in a range between 10° and 45° relative to the tubular conduit on which the plurality of nozzles are disposed;
a camera head disposed on the front end of the housing; and
a further nozzle being disposed on and in fluid connection with each of the plurality of tubular conduits, the further nozzle of each of the plurality of tubular conduits facing forward toward the front end of the cage so that when the pressurized gas passes out through the further nozzle of each of the plurality of tubular conduits, the pressurized gas passes forward of the front end of the cage, the further nozzle of each of the plurality of tubular conduits being spaced apart from the housing and the camera head.
