These tools are a great fit for my model of Shark. Shark DIDN'T even carry the variety of replacement tools for my model. With the adaptor pieces, it seems they would be a universal fit. The quality is very good, though not OEM. But when your manufacturer stops making replacement part for equipment that is only 3 years old, you have to look elsewhere. I am glad I found this allotment and have a very useful array that Shark never offered and very adaptable. They hold up to do all the jobs I need to do. More than happy and satisfied
