I've had great luck with iRobot replacement parts for filters and brushes, so I expected the extractors to be just as good. Unfortunately, these extractors are MUCH NOISY. Once installed, my Roomba makes a lot of extra noise while vacuuming my tile floors, to the point where it's very distracting. To be honest it sounds like the plastic doesn't quite fit and is rubbing against either another hood or the bottom of the Rumba. The noise sounds like rannnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn constantly as it vacuums throughout the house. I won't be buying these again and had to throw in extra money for some proper extractors. If you're using a Roomba 960, be careful. I would not recommend these
