This 3″ STINGER Duct Cleaner comes with a 20’ hose and quick connects so you can switch from hose to wand cleaning effortlessly. Clean vent hood tracks and plenums, or switch to a hose and send it down ductwork. Revolutionizing Efficiency in Hood Cleaning: The 3″ STINGER Duct Cleaner is engineered to transform how professionals tackle hood cleaning jobs. Its Variable Speed Control optimizes performance, allowing slow RPM operation to deliver a high-PSI spray pattern that stays consistent over longer distances — making it perfect for large-diameter ductwork. Whether cleaning vertical or horizontal systems, hard-to-reach corners, the STINGER delivers unmatched cleaning. Why Professionals Choose the STINGER: Reduced Downtime: Low RPM minimizes friction, preventing seal and bearing failures while enabling full use of your washer’s heat output. No Compromises: You don't have to turn down the PSI to prevent seizure. You can control Stinger RPM as full PSI by adjusting the wash arm angles. Cost Savings: Slash labor, chemical, and fuel expenses with a tool built to work smarter, not harder. Durability Meets Innovation: Includes the next-gen Stinger Cage (see below) for drop-proof protection and tool-free maintenance. Next-Gen Stinger Cage: Impact-resistant Protection, Zero Hassle Say goodbye to bent metal cages. The new Stinger Cage redefines durability with its impact-resistant molded design, engineered to withstand rooftop drops, job site abuse, and daily wear. Specifically molded to fit STINGER duct spinners, this two-piece cage snaps together seamlessly via male/female tabs and is secured with three heavy-duty rubber O-rings (top, middle, bottom). Why Upgrade to the Stinger Cage? Drop-Proof: Proprietary blend of rigid rubber construction bounces back — no bends, no breaks, no replacements. Instant Access: Pop off the O-rings to adjust wash arms, replace nozzles, or service seals in seconds. Perfect Fit: Precision-engineered for STINGER brand duct spinners, ensuring flawless compatibility. Included with every STINGER Duct Cleaner, this cage isn’t just an upgrade—it’s a long-term solution for pros who value reliability and efficiency. What separates the Stinger from other duct cleaners is our revolutionary “Variable Speed Control Head Technology”. By simply adjusting the angle of the spray arms on the cleaning head, you can adjust your cleaning RPM from 0-3200 while not giving up any volume, pressure or temperature of your pressure washer. Other cleaning heads on the market have a fixed of about 3200 RPM which results in a premature bearing loss, seal lockups and ineffective cleaning. Bottom line, speed kills. Slowing the RPM down sounds counterintuitive for speeding up cleaning, but think of it this way. If you were using a pressure wand and you whisk back and forth quickly over a piece of gum, for example, the gum simply won’t move. However, if you hold the nozzle on the surface for just 1 second, you allow the water pressure to penetrate into the surface resulting in a deeper, more effective clean. By running a cleaning head at a lower RPM with full pressure, you allow the wash arms more time to blast full penetrative power at the surface which results in deeper, faster cleaning that also happens to protect your equipment from seal and bearing failure. You get professional, longer-lasting equipment that cleans better and works faster.
