Multi-surface rubber brushes (long cylinders in light and dark gray) look almost exactly like iRobot parts. That was the main reason I bought the set. However, they are not identical. Both my 960 and 980 made horrible noises when vacuuming and their batteries drained much quicker. Can't attest to the sanctity of what HEPA filters are supposed to be. I doubt they filter much, but at least they don't cause device crashes. The little side "vacuum cleaner" seems to work well. You just don't get quality for the price, and the annoying noise of the long rubber brushes keeps most conscientious users from even trying them. try to save. Screwed up with a poor quality product. From now on I only buy official iRobot parts.
