The answer

What to know.

The serial number of the Dolphin robot is a 10-digit number that can be found inside the robot on a white sticker.

If your filter opening is on the bottom of the robot:

  1. Turn your Dolphin upside down and remove the filter(s).
  1. Look for a white label (sticker). This label has your robot's serial number on it.

If your filter opening is on the top of the robot:

  1. Open the top lid and remove the filter(s).
  1. Look for a white label (sticker). This label has your robot's serial number on it.

If the serial number is not accepted during the registration process, verify that the characters are entered correctly.
