Where does it park when it's done? Does it know when it has covered the entire pool or does it keep goning until the battery is low?

In Standard mode, it will keep cleaning the pool until the battery is low and then stop at the side of the pool.

In Fast mode, it will clean the entire pool twice and then stop at the side.

Automatically stop by the nearest wall after the clean is done, ready to be retrieved with the Hook or the floating ring.

However, if the battery is low during the cleaning process, it will go to the side of the pool and stop.

We recommend that you charge the robot before using it for the first time.

During the charging process, the two outermost indicator lights are in a breathing state until fully charged, when 11 white lights are on.
