Always stays attached to my cordless cylinder vacuum. Great brush/head. Knowing that it needs to be tilted slightly to "invite" the dirt helps make it more efficient. The bristles on the brush will soften a bit with use, which is a good thing as they are very stiff when new. UPDATE after a few months of use - the swivel where the "neck" connects to the brush body is wobbling. I'll admit I'm pretty aggressive at times when it comes to sanding the floor mats, but at this rate I buy two a year. It's ok, but I'll try it with a metal bar to see if durability improves.
