I really like this replacement brush. It's actually better than the original that came with the vacuum because the spiral pattern of the bristles on one end of the brush is about a third of the way in the opposite direction. Where the two circuits meet is exactly where the vacuum inlet is, which is about a third of the way in one direction, not all the way in one direction. The original that came with the vacuum had a continuous spiral pattern on the brush that collected all the dirt at one end. While it's a small difference and you probably won't notice a difference in cleaning power, this replacement brush is slightly more efficient at transporting debris straight to the cleaner's inlet. It's also not difficult to install.
