Abstract
Apparatus is disclosed for cleaning a sewer or other chamber. The apparatus includes a wheeled vehicle having a frame. A water reservoir tank is mounted near the front of the vehicle frame and is adapted to hold a supply of water. A hose unit is mounted at the rear of the vehicle frame. The hose unit has a hose connected to the water reservoir tank and adapted to be inserted into the chamber to discharge water into the chamber. A debris holding tank is mounted on the vehicle frame between the water reservoir tank and the hose unit. The debris holding tank is adapted to receive and hold debris. A boom is mounted on top of the debris holding tank and adapted to extend rearwardly over the hose unit. The boom has a conduit connected to the debris holding tank and adapted to be lowered into the chamber to be cleaned to transport material from the chamber into the debris holding tank. The location of the debris holding tank amid the water reservoir tank and the hose unit permits the boom to extend over the hose unit and be used in conjunction with the hose paid out from the hose reel. The position of the tanks also permits an even weight distribution on the vehicle frame.
