Third for a four year old vacuum cleaner. I have never seen such a disposable brush. The plastic breaks where the bearing is, causing the vacuum to vibrate horribly. In fact, Dyson recommends replacing them once a year, probably because they know they're junk. I've had ricars and even vacuums that have lasted ten years with no problems.
