Corner cleaning

How i get corner clean . I noticed extension mopping is not done every time . What setting should be change so it will clean the corner every time.
And i have one more issue sometimes dock doesn't start i have to turn it off and on few times

Hi, You can set mop extension to high frequency so that it extends the mops everytime it cleans the edges.

For dock On/Off issue, please check if the wire is connected tightly behing the dock station, sometimes if there it loose contact, it may happen. Also, keep the small white switch on dock station always ON
