Purchased with my Bissell Zing (4122) which works great on my hardwood floors but has a hard time picking up cat fur from the medium pile living room carpet. I wasn't really expecting it to work that well, but figured it was cheap enough to at least try. I was pleasantly surprised when I put it on the end of the wand and turned on the vacuum cleaner - it immediately started rotating with good power. I tried it on my carpet and it worked like a charm! I'm so glad I finally got rid of that permanent layer of fur on the carpet that felt like a losing battle. All the happier that I didn't have to buy a new vacuum cleaner just for a carpet in my house!
