Roomba 500, 600, 700, 800 or 900 series Front Castor assembly. This castor wheel is easy to replace.
We advice to clean this front castor wheel regularly. You can take the wheel out of the vacuüm cleaner and click the black and white wheel out of the holder. This way it is easy to clean the axis.
Depending on the floors Roomba® will be driving around the front wheel will wear out sooner or later. Specialy on a rough floor we advice to check if your Roomba® keeps connecting to the homebase. If not it is possible you have to replace its frontwheel.
