A portion of this product is difficult to test. I have ordered a complete replacement for my Shark professional vacuum cleaner. QINAN Vacuum Cleaner Filter + Brush Roll Replacement Compatible with Shark Rotator Pro Lift-Away NV500 NV501 UV560 NV502 NV505 NV550 NV520 1 HEPA Filter, 2 Foams, 1 Roller Brush I was only able to replace the foam filter. The rest requires tools I don't have. They had some kind of screwdriver in them, but I don't know what they're supposed to be used for because they didn't fit anywhere. Installation instructions were not included for any of the parts.
