Not suitable for my Shark Rotator Professional (NV500 series). But you can't really tell until you try it. I ordered it, tried it, but it didn't fit the Shark. When I clicked on the return option, I was told that a return is not possible. When I followed the link to explain why it was non-refundable it was just general information. Nothing specific to this product or order. As far as I can tell, the product listing page I ordered doesn't say it's non-refundable.
