The contact points on the Roomba may be dirty. Roomba's charging contacts are under the front bumper of the robot. This means that they are in front of the brushes, and see a lot of debris. They can easily get dirty and increase the resistance in the charging circuit. If after cleaning the contacts, the Roomba will still not charge correctly, you may need to replace the battery or get a new charging dock.
