What cleaning modes are available on the P20 Robot Vacuum Cleaner?

The P20 offers five cleaning modes: Auto Cleaning (zigzag pattern followed by edge cleaning), Spot Cleaning (zigzag route in a specific area), Spiral Cleaning (spiral route from the center of an area), Edge Cleaning (follows and cleans along walls), and Scheduled Cleaning (starts automatically at a set time). All modes except Scheduled Cleaning can be activated via the remote control or the AIRROBO app. (Page 9-10)
