He was thinking about adding a gps tracker onto it for safety. 

I am a fan of checking in occasionally to make sure the cleaner is on top of things and to do a walk through to check safety things like deck boards and steps, railings etc.

From either a safety standpoint or because the property couldn’t meet my standards of being a nice place to live (not a slum property).

Is this possible with an Arm?
