I had bad luck with this product. The belts broke easily. The beater bar notches were stripped easily. My mother was using it so I wasn't present when the other belts broke and the beater bar was destroyed. She's not incompetent and knows how to correctly operate a vacuum.I tried using the attachment on my couch and on the stairs. The rotating rubber bristles, for lack of a better word, kept stopping if I applied any pressure to the attachment.
