It’s not as efficient as a spinning brush attachment [SEP] It’s not as efficient as a spinning brush attachment. I got both bc I’m desperately swimming in dog hair. Maybe she’s got a medical problem, but it’s really bad. She hates this on because it’s so scratchy. It’s a cool idea, but she is happier with the spinning rubber tooth attachment. It’s louder and harder to use bc it doesn’t fit my vacuum, but it’s so much more effective. Half of a vacuum was filled up. Idk if my Shepard is going bald or not. She needed a serious solution.
