Detailed Description

The RIDGID K9-204+ FlexShaft Machine is the next evolution in flexible drain cleaning technology. Designed for mid-size lines commonly found in commercial buildings, restaurants, apartments, and municipal facilities, it gives technicians unmatched efficiency and precision. This upgraded “plus” version builds on RIDGID’s proven K9-204 design, adding latching access doors, an improved cable clamp, and on-board tool storage to streamline setup and maintenance.

The system’s 70′ (21.3 m) of 5/16″ (8 mm) FlexShaft cable is enclosed within a durable nylon sheath, protecting both the operator and the workspace. Inside the pipe, centrifugal chain knockers spin at high speed to remove grease, soft roots, and hardened scale—without using chemicals or excessive pressure. As the chains expand, they scour the full diameter of the pipe, restoring maximum flow and extending line life.

Setup and cleanup are exceptionally quick thanks to the machine’s fully enclosed system. Simply plug in, position the drum, and activate the foot pedal for instant rotation. Because the cleaning action occurs inside the flexible sheath, debris is contained, leaving the work area cleaner and safer. Technicians can even use a RIDGID SeeSnake® inspection camera simultaneously, confirming results in real time and documenting before-and-after footage for customers.

Mobility and ease of use are also central to the design. The K9-204+ weighs less than many comparable machines, making it easy to load, transport, and position on-site. For multi-level service environments, its compact frame and durable construction ensure reliable performance across repeated daily use.

In summary, the RIDGID K9-204+ FlexShaft Machine provides fast, chemical-free cleaning for professional plumbers and maintenance crews who demand efficiency, precision, and jobsite cleanliness. The key benefit is complete, wall-to-wall cleaning with camera verification—all in one portable, enclosed system.
