Actually I only used the filter parts of this product. The first thing I noticed was that the blue filter was even tighter than the original, which can't be bad. I won't need any other parts yet, but for now I'm very satisfied. Update: Everything worked very well until I replaced the main brush for the second time. The vacuum runs for less than 5 minutes before I get a "main brush failure" alert. Very annoying. Would like to speak to the company to get a replacement. Apart from this problem I was satisfied.
