Just to be sure, a low blinking blue light (one flash per second) means the DFI sensors is active and a fast blinking blue light (4 flashs per second) means the same ?
I have a fast one.
If the blue light is blinking and the waste drawer is empty and the sensor has been cleaned properly but the issue persists, then the sensor has gone defective and needs to be replaced.
Your robot is under warranty so we will send you a new DFI sensor.
Please provide us with the following:
1- Shipping address.
2- Phone number.
3- Serial number located on the back of the robot.
You can send us these details via private message for more secuirty.
