The RIDGID K9-204 (64273) FlexShaft Drain Cleaning Machine is a lightweight, highly efficient machine that delivers wall-to-wall cleaning in 2 in. to 4 in. drain lines up to 70 feet. The K9-204 FlexShaft machine can be operated while an inspection camera (sold separately) is in the line, letting you see while you clean.

The K9-204 FlexShaft machine utilizes a specialized chain knocker that is attached to a flexible cable, which is spun at high speeds by a cordless drill attached to the center drive shaft (drill sold separately). The cable assembly is manually fed in and out of the drain, and the chain knocker expands to the pipe's inside diameter to break up the blockage and clean the walls of the pipe. Since the cable spins inside a durable nylon sheath, which is housed within a fully contained drum, there is less jobsite mess.
