Awesome on cat hair. I use this Black + Decker dustbuster® Hand Vacuum Pet (Purple) on my sofa's and carpet. I love my cat but he sheds so much. And with cat hair all over the place. I am so glad that the Black + Decker dustbuster works perfect for the job. It gets up all the cat hair. And all the little crumbs that my kids get embedded into my sofa. I love Black & Decker and their products. They are an Awesome Brand.
