Abstract: An automatic hose rotation mechanism for a suction excavator. The rotation mechanism operates to partially rotate the flexible hose around its longitudinal axis during a normal operation cycle. This means that the hose is regularly turned about its axis without having to detach it from the vehicle. The invention therefore reduces time required for vehicle maintenance and increases the lifetime of the flexible hose. The suction excavator may have a debris suction mechanism with a pivoting lid. A rotation mechanism for the flexible hose may couple one end of the flexible hose to the lid section so that the flexible hose rotates when the lid section pivots from the closed position to the open position.
