1. An apparatus for removing residual concrete from an interior of a rotatably mounted ready mixed concrete truck drum, comprising:
an elongated boom, wherein the boom is configured to be inserted into the drum generally along a longitudinal axis of the drum;
a nozzle housing hingedly connected to a leading end of the boom so that the nozzle housing is positionable in a plurality of angular positions relative to the boom, wherein the nozzle housing includes:
a high-pressure nozzle rotatably mounted within the nozzle housing;
a motor configured to oscillate the nozzle about a stroke length;
an encoder configured to monitor the position of the nozzle along the stroke length;
a controller in operable communication with the motor and the encoder, wherein the controller is configured to dynamically alter the stroke length and includes an actuator to fix the nozzle at a location about the stroke length;
a source of high-pressure water fluidically coupled to the nozzle;
whereby the nozzle directs high-pressure water into residual concrete contained within the drum to clean the interior of the drum.
