What cleaning modes are available on the Airrobo P20?

The P20 offers five cleaning modes: Auto Cleaning (zigzag pattern finishing with edge cleaning), Spot Cleaning (zigzag route from a specific area), Spiral Cleaning (spiral route from the center of an area), Edge Cleaning (cleans along walls automatically), and Scheduled Cleaning (set a time via the app). All modes except Spot and Spiral will automatically return the robot to the charging base when complete. (Pages 9-10)
