I recently came across a string of web articles on numerous thefts of robotic cleaners from backyards. I could pull the cleaner out of the pool after every use, but that would defeat the primary convenience of running it on auto-schedule. Has anyone come up with a deterrent to this potential problem? Trackers would be viable if they were waterproof; but they're not. A dog would do the job, but that seems a bit much. Any suggestions appreciated.
