I love my Sebo! I didn't really know what effect a simple brush change would have. It was like putting it back into almost new condition. I didn't realize how worn my brush bristles were and how it would affect my vacuum's performance. Replacing it with a new brush is definitely worth it. Installation was easy. I got it done in less than 2 minutes. It took a little effort to significantly improve the cleaning process! I highly recommend the brush.
