This disclosure describes inspection tools and methods to inspect and maintain the interior of vent gas manifold channels. A magnetically-coupled probe, (e.g., a ball, cylinder, rectangular cube, or disc), is inserted inside the vent gas manifold channel. A magnetically-coupled head then magnetically drags the magnetically-coupled probe through the channels of the vent gas manifold. The inspection tool uses a sensor to monitor the position of the magnetically-coupled probe inside of the channel. If an obstruction is encountered, the sensor monitors local changes in one of more physical or electrical properties of the inspection tool and alerts an operator. The magnetically-coupled probe may be a steel bucket with sharp leading edges that detaches and scoops up the obstruction. A programmed robot manipulator arm or human operator may move the head across the surface of the vent gas manifold parallel to the channel.
