A system for removing waste material from the bell end of a cast iron pipe is disclosed. The system has both a cleaning assembly and an exhaust system. The cleaning assembly has a plurality of wire brushes mounted on a shaft. The shaft is mounted on a cart that also supports a movable part of the exhaust system. The cart moves the wire brushes and part of the movable part of the exhaust system into and out of the bell end of the pipe. A motor on the cart rotates the shaft and brushes, and a tilt mechanism tilts the brushes down to contact the pipe. The pipe is rotated about its central longitudinal axis as the brushes contact and clean the pipe. The rotating brushes clean the sand core from the end of the pipe, and the waste sand is drawn by the exhaust system to the bag house where it is filtered. The exhaust system also includes a stationary duct. The stationary duct has a door and a chute. Larger chunks of waste sand can be removed from the exhaust system through the door and chute.
