[When to Change] The cyclone baffle bin runner helps support the dust bucket components. If you experience difficulty opening the dust bin lid via the slide rail during garbage removal, causing the bin to fall off, inspect the triangular part on the support plate of the cyclone separator. If it is missing or damaged, replace it with a new bin runner for proper operation. [Easy to Replace] The bin runner comes with disassembly tools, making it easier to remove and install. Follow the included installation video for guidance—the entire process takes only a few minutes. Be sure to keep your screws secure to prevent loss, as they are a special size. Replacement screws may be available in our store if needed. Upgraded and Stronger Design – Features an exclusive widened stress point and an enlarged release bin switch handle design, allowing easier dustbin release and effortless emptying. The improved handle integrates seamlessly with the opening mechanism. The updated opening handle is compatible with the switch lever. Previous versions were shorter and narrower; this version has been upgraded for better ergonomics, improved grip, and reduced finger strain from repeated use. Perfect Compatibility – This dust box red lever repair kit serves as a direct replacement for the trigger opening switch button on V10, SV12, V11, SV14, V12, V15, and Gen5 models.
