Ability to change the unit in the Robot Vaccum app from ft2 to m2 (Metric Measurements)

As a non US it would be great if I can have the option to change the room area from ft2 to m2. Should be a simple fix from the developer point of view.

[Mod Edit]:Title Modified to Enhance Search Clarity.

Could you please add the option for square meter (instead of square feet) for the Robot Vacuum?
