Not Eureka branded but they work as well or even better than the original for a small price. I always ran out of bags and had to make extra trips to the store to buy them. This 36 pack should last you for a while. My only complaint is that the seal that goes on the opening (when the bags are filled and removed) sometimes loses its stickiness and doesn't seal the full bag - it's a small piece. Duct tape solves this problem.
