Drain cleaning drum machines unwind cable from their large drum and automatically rotate the cable to break through roots and blockages in floor drains and main sewer lines. They clean longer runs and larger-diameter pipe than drain guns and augers, and the continuous length of cable allows a smoother feed than sectional machines. Their frame provides a stable base that supports the drum and positions cable at the front of the machine to ease access for unwinding. They wind cable onto the drum for storage and keep it contained in the drum housing, reducing mess and splatter.
