Includes 3 sets of spare brushes (6 total), main brush and spare carbon cartridge filters. Replacing all parts takes about 20 seconds - the small brushes slide out immediately and the new ones are inserted immediately. I noticed that they held up better than the previous non-original brand when the previous ones came out and I found them on the floor. They have held up well during operation, for which I am grateful to them. The main brush is also very easy to replace, simply flip up the tabs, take out the old brush, insert the new one, close the door and you're done. Changing the filter doesn't hurt either. One drawback - the quality of the brush is not very good. After a use or two they started to wear out but they still do a good job - they're longer than the last set I bought and the whole set is cheap so no complaints.
