Best Drain Cleaning Machines for Small Lines Ranked

7 drain cleaning machines with a 3/8 in cable or thinner.

Last updated: November 3, 2026

A small line machine comes with a 3/8 in cable or thinner, which bends through the tight traps of sinks, tubs, showers and floor drains of about 1-1/2 to 3 in. Most are drum machines on a wheeled cart with a foot pedal. Pro makers rate this cable to about 3 in, so a listing that promises 4 in or more from it is stretching.
