Putting in the model number SV75 says they fit and they fit. Difficult to get in far enough for the vacuum to re-engage, and even more difficult to open the vacuum to pull it back out. For old or arthritic hands, this can be a big problem. Looking at the model numbers on the side of the box, SV75 isn't even listed, so are they really for SV75? Models indicated on the box, see photo.
