This is the same machine - for public use - it fits Pet Perfect II, purple handheld vacuum I don't give 5 stars , because their design isn't perfect - they absorb dirt - so you have to physically remove dirt/hair/nasty things from the filter, and - they're not very strong so they tear easily. after a few months of use. However, if you have a Pet Perfect II or any other Shark Vac, you kind of get stuck with them. They work.
