iRobot® Roomba® s9 green extractors. The extractors are used inside your S9 brushmodule. Because of the circular movement they extract dirt from your floor. If used a long time or when it hits on some very sharp objects on his path the extractors get damaged. They are easy to replace.
We advice you to remove the extractors from your machine regularly to clean out the dirt that sometimes will be stuck inside the extractors. Just remove the extractors and pull off the bearings on the sides of those extractors and clean out the dirt underneath. Just a little bit of maintenance will make your Roomba much longer.
