If the red 
full bin indicator is illuminated or blinking, it means Roomba® senses that the bin is full. Please empty the bin, and clean the full bin sensors and sensor ports thoroughly. If Roomba® continues to indicate the bin is full after you have emptied the bin, it means you have not thoroughly cleaned the bin full sensors and/or the sensor ports.
