Warranty Replacements and Returns


To begin a Warranty Replacement or Return, or for any other Technical or Customer Support related questions, please email us at support@modrobotics.com!

1-Year Warranty on Modular Robotics products:
Did you know that your Cubelets and/or MOSS robots purchased through Modrobotics.com or through one of our resellers like Amazon or RobotLab are under warranty for one year from the purchase date?

With proof of purchase, we’ll repair or replace your robots within one year even if you dropped a Cubelet in the pool, the dog buried your MOSS Motor in the yard for a fortnight, or your robot blocks simply aren’t working the way they should. Modular Robotics reserves the right to reject warranty items that have been intentionally abused.

If your robots are defective or misbehaving in some way, please email us at support@modrobotics.com with your proof of purchase, explaining as best you can the issue you are observing. We may be able to help you fix the problem yourself, but if not, we’ll be happy to repair or replace your robots!

After you’ve contacted our Customer Support team, you will be asked to send items for repair or replacement to our factory at the address below:
