It sounds like you are having some issues with your Neato D80 robot vacuum. Here are a few things you can try to troubleshoot the problem:
Make sure that the bin is properly closed and seated in the vacuum. If the bin is not closed or seated correctly, the vacuum may not function properly.
Check the battery to make sure it is fully charged and properly installed in the vacuum. If the battery is low or not properly installed, the vacuum may not function properly.
Check the charging cord and charging port to make sure they are not damaged and are making a proper connection.
If the problem persists after trying these troubleshooting steps, you may need to take the vacuum to a repair center for further diagnosis and repair.

Press and hold the Start Button for 10 seconds. The robot will turn off. Press the Start Button again to turn the robot back on. Wait for the beeping sound to confirm the robot finished the reboot sequence.
