A method for specifying a cleaning area to a cleaning robot without an in-built map provides a hand-held mobile device capturing a two-dimensional code label arranged on a top of a cleaning robot parked on a charging base, and obtaining a positional relationship between the mobile device and the cleaning robot through the captured image. The cleaning robot is controlled to enter a cleaning mode under the guidance of the mobile device. With captured images, a user can specify an area within the environment for cleaning, and through a touch display screen can control the cleaning robot to go to the specified cleaning area for cleaning. The mobile device and the cleaning robot employing the method are also disclosed.

One object determining system comprising: an air ejection device, configured to eject air; a distance detecting circuit, configured to detect distances between an electronic device comprising the object determining system and at least one location of an object when the air ejection device ejects air to the object; and a determining circuit, configured to determine a type of the object according to variations of the distances.

There is provided a cleaning robot including a light source module and an image sensor. The light source module projects a horizontal line pattern toward a moving direction. The image sensor captures, toward the moving direction, an image of the horizontal line pattern. The light source module is arranged below the image sensor so as to eliminate the interference from second reflection.

Apparatuses, machine-readable media, and methods related to cleaning detection are described. A cleaning detection system can be used to determine whether there is a need for cleaning by comparing detection inputs, from sensors of the cleaning detection system, that are associated with an updated status of an area to a baseline status of an area. The cleaning detection system can receive a number of initial inputs associated with an area scanned by the device, determine a baseline status of the area based on the number of initial inputs, receive a number of detection inputs associated with the area scanned by the device, and determine whether a location of the area is in need of cleaning based on a comparison of the baseline status and the number of detection inputs.
