RIDGID-204B flex shaft drain cleaner

Whether you're servicing residential kitchens, commercial drainage systems, or bathroom waste lines, the RIDGID-204B delivers fast, efficient, and reliable cleaning performance.

Key Features

High-Speed Cleaning Performance

Powered by an 18V lithium battery, the machine operates at 1,000–2,000 RPM, providing powerful rotational force for efficient drain cleaning.

Three Cleaning Modes

One machine performs three essential functions:

  • Break through blockages
  • Crush stubborn deposits
  • Clean pipe walls thoroughly

This significantly reduces repeat service calls while restoring optimal pipe flow.

Long 21.3m Flexible Shaft

The 21.3-meter (70 ft) flex shaft reaches long drain runs with ease, making it ideal for:

  • Residential plumbing
  • Commercial buildings
  • Restaurants
  • Apartment maintenance
  • Indoor and outdoor drainage systems

Dual Chain Knockers Included

Supplied with both:

  • 2" Smooth Chain Knocker
  • 4" Smooth Chain Knocker

These rotating chains effectively remove:

  • Grease buildup
  • Soap scum
  • Mineral scale
  • Sludge
  • Tree roots
  • Organic debris

Cordless Battery Operation

The cordless 18V lithium battery design provides:

  • Excellent portability
  • No power cord limitations
  • Convenient indoor operation
  • Faster setup on job sites

Flexible Shaft Design

Compared with traditional drain snakes, the flexible shaft rotates at much higher speed, allowing the chain knockers to clean the entire pipe wall instead of only punching through the blockage.

This results in cleaner pipes and longer-lasting drainage performance.
