A cornerstone of Goodway, the Soot-A-Matic was first introduced over 30 years ago. Now in its third generation as the SAM-3, it is the world's most popular system for cleaning firetube boilers. The unit is compact, portable and easy to use. One operator can thoroughly clean a boiler in a fraction of the time required by other cleaning methods - all by flipping a switch. Interchangeable bayonet nozzles and cleaning tools are available to fit tubes 1-3/8"-4" (35-102mm) O.D. The SAM-3 uses a cleaning tool mounted to the tip of a 26' (7.9m) spring steel tape. A trigger switch controls tape feed. The operator inserts the nozzle into the boiler tube and pushes the trigger forward.

The cleaning tool travels the full distance of the tube at more than 3' (0.9m) per second, loosening soot and scale. The operator pulls the trigger back for cleaning tool return and moves to the next tube. A GTC-540 Soot-Vac vacuum, connected to the tube through the SAM-3, simultaneous removes loosened deposits.
