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.

Abstract: A sewer cleaning unit is disclosed which comprises a single tank assembly mounted on a wheeled vehicle. The single tank assembly has a substantially horizontal fixed divider forming a first tank portion adapted to carry and discharge a supply of water, and a second tank portion adapted to receive and hold debris, thus obviating the disadvantages of tank designs of the prior art. The unit may also be provided with hand-operated control means near the intake end of the conduit connected to the second tank portion and a control means connected to the reel for the hose from which water is discharged from the first tank portion, the reel control means and the hand-operated control means capable of being operated simultaneously by a single operator.
