4.3.2 Operation modes
Map Management
A. Real time mapping
Real time creation of a house map may help you understand the cleaning route and the cleaning environment easily. A map of the house is created after cleaning. The map is updated in real time during each vacuuming operation to ensure a normal navigation. To create a complete house map;
a. Open the doors of your rooms for the robot vacuum cleaner to map each room;
b. Remove any objects that may cause obstruction or blockage of the robot vacuum cleaner;
c. Do not change the location of the charging dock or unplug it after the map is created.
B. Repositioning and remapping
If the robot vacuum cleaner is relocated or significant changes are made in the environment, the robot vacuum cleaner tries to reposition to adapt to the new environment and may create the relevant map again. The details are as follows:
a. If repositioning is successful, the robot vacuum cleaner continues on cleaning;
b. If repositioning is unsuccessful, the robot vacuum cleaner starts over to scan in order to make the mapping again.
WARNING: Ensure that the robot vacuum cleaner always starts the cleaning operation from the charging dock.
During cleaning, do not intervene in the robot vacuum cleaner or change its location.
Room cleaning mode (Supported by the relevant mobile application only)
You may specify the rooms you want to be cleaned with the mobile application, then the robot vacuum cleaner cleans only the room(s) that is/are marked in the map.

• The robot vacuum cleaner may also enter the areas other than the selected area after it starts cleaning; thus please remove the obstacles on the ground around the selected area. Area selection does not provide a secure isolation.
• Regional cleaning may only be started after the robot vacuum cleaner successfully creates a map.

Regional cleaning mode (Supported by the relevant mobile application only)

The dimensions of the region can be determined by holding from the right bottom corner. In the meantime, the dimensions of the displayed area are written on the screen with the dotted line.
Select regional cleaning mode in the application and then specify a cleaning area. The robot vacuum cleaner only cleans the selected area and then returns to the charging dock.

• Regional cleaning may only be started after the robot vacuum cleaner successfully creates a map.

Refer to the mobile application operation manual for detailed usage tips.
