Cleaning apparatus and method for controlling the same

A cleaning apparatus comprising:

• a robot cleaner comprising a brush configured to scatter dirt by scrubbing a surface to be cleaned and a mop configured to clean the surface to be cleaned by contacting the surface to be cleaned;
• and
• a station on which the robot cleaner is placeable,
• wherein the robot cleaner further comprises:
• an air jet device configured to spray air onto the surface to be cleaned,
• a camera configured to obtain an image of the surface to be cleaned,
• memory, comprising one or more storage media, storing instructions, and
• a processor communicatively coupled to the air jet device, the camera, and the memory,
• wherein the instructions, when executed by the processor, cause the robot cleaner to:
• determine to spray air onto the surface to be cleaned through the air jet device based on the image obtained from the camera, and
• identify a target object as liquid based on a shape change of the target object included in consecutive images obtained from the camera before the air jet device sprays air onto the surface to be cleaned and after the air jet device completes spraying air onto the surface to be cleaned.

• determining to spray air onto the surface to be cleaned through the air jet device based on the image obtained from the camera;
• spraying, by the air jet device, air onto the surface to be cleaned;
• obtaining, by the camera, consecutive images of the surface to be cleaned while air is sprayed onto the surface to be cleaned;
• and
• identifying a target object as liquid based on a shape change of the target object included in the consecutive images obtained from the camera.
