Steve,
Each pool and location is a little different.
In my case, I only put the robot in the water once or twice a week, so I don't really schedule..
If you plan to leave the robot in the pool all the time, then just schedule it based on how dirty your pool gets... It can't hurt to run it once a day.
The app lets you select a time to run each day, and what days you want to run. It will just keep repeating that schedule..
Thanks,
Jim R.
