The Secret Behind STINGER's Superior Cleaning Power: Variable Speed Control Head Technology

What truly sets the STINGER Duct Cleaner apart is our patented Variable Speed Control Head Technology — an innovation that redefines how duct cleaning should work.

Unlike conventional duct cleaners with fixed-speed heads spinning at 3200 RPM, the STINGER lets you take control. By simply adjusting the spray arm angles, you can fine-tune the cleaning head’s RPM from 0 to 3200 — without sacrificing pressure, volume, or heat from your washer.

Why Fixed-Speed Heads Fall Short

Traditional duct spinners operate at a single high speed, which causes:

• Premature bearing failure
• Seal lockups
• Ineffective cleaning from rushed water impact

Why? Because speed kills — especially when it’s uncontrolled.

Why Slower RPM = Faster, Deeper Cleaning

It might sound counterintuitive, but slowing the spin actually speeds up your cleaning. Imagine trying to remove gum with a pressure wand:
Quickly sweeping over it does nothing. But pausing the spray for just one second? The gum lifts right off.

The same principle applies with the STINGER.

At lower RPMs, the wash arms spend more time blasting each surface point — giving the full force of your washer a chance to penetrate grease and buildup. The result?
Faster, deeper cleaning with less effort and wear on your gear.

The STINGER Advantage

• Fully Adjustable RPM (0–3200) – Dial in exactly the speed you need for each job.
• No Performance Loss – Maintain full PSI, flow, and heat at all speeds.
• Extended Equipment Life – Reduced friction means fewer breakdowns and lower repair costs.
• Better Results in Less Time – More power where it matters = less time on the job.

Precision control. Deeper cleaning. Longer equipment life.
That’s the STINGER difference — built by professionals, for professionals.
