After 10 years of use, my Shark needs new parts to pick up dog hair like it used to. I watched a video online and saw this HEPA roller filter replacing the kit to restore lost suction. After removing over a dozen bolts (a pain) just to replace the reel, I found other parts that I needed to replace (the short flexible hose had snapped over the years). After I received the remaining parts, the assembly went smoothly. Now my Shark collects dirt and dust like before.
