Depending on where you are from it seems you may call it a Agitator, a Brushroll, or a Beater Bar. They are all the same thing, the bar that rotates with bristles on it to help pick up dirt and brush through your carpet for better cleaning. In our neck of the woods we call it a "Brushroll". So if this is what you need we hope you now can find it.

Brush rolls, beater bars, agitators are a very important part of the vacuum cleaner. They tend to be overlooked in the upkeep department of the vacuum, but really are essential. They are the first to encounter the dirt, carpet, pet hair, paper clips, rocks and whatever else is on the floor. And Usually they are the last thing that gets attention. The bristles are a very robust nylon based material but they are not invincible. The bristles still get worn out. The least expensive vacuums brush roll may not last that long, and the very high quality vacuums brush roll may go a long time before they experience any issues. The bristles can show wear different ways. Loss of bristles from the bar. Bristles that are shorter than they were. The bristles are not the only part that get worn out. The place where the belt rides can get worn or grooved. The bearings or bushings can get worn out as well. If a vacuum cleaner has trouble breaking belts or if you smell the “burnt rubber” smell than the brush roll could be the culprit. Hair or carpet fibers can get caught round the end preventing it from spinning or spinning freely. Some times if it has had this problem for too long then it can cause the holding area for the brush roll to become damaged. Vacuum cleaner brush rolls should be examined regularly to make sure that they spin freely and that there is not a bunch of things wrapped around it. If it does not operate as it is supposed to then your carpet will not get as clean as you remember.
