Cleaning area selection method and device

A non-transitory computer readable storage medium carrying one or more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the steps of:

• obtaining a secondary selectable area to be cleaned, comprising:
• dividing the area to be cleaned into at least two sub-areas to be cleaned;
• classifying the at least two sub-areas to be cleaned into a large sub-area to be cleaned and a small sub-area to be cleaned according to sizes;
• acquiring a boundary line between the large sub-area to be cleaned and the small sub-area to be cleaned;
• and extending the boundary line to form an extended boundary line and determining whether the extended boundary line divides the large sub-area to be cleaned, wherein if yes, a first sub-area to be cleaned that is located on a same side of the boundary line as the small sub-area to be cleaned, and a second sub-area to be cleaned that is located on a different side of the boundary line from the small sub-area to be cleaned are acquired;
• establishing a communication relationship between the small sub-area to be cleaned and the first sub-area to be cleaned, and establishing a communication relationship between the small sub-area to be cleaned and the second sub-area to be cleaned;
• and using the first sub-area to be cleaned, the second sub-area to be cleaned, and the small sub-area to be cleaned as at least three secondary selectable area to be cleaned;
• and
• controlling a floor-cleaning robot to move by one unit length in a first direction, and determining whether a current location of the floor-cleaning robot is the secondary selectable area to be cleaned, wherein
• if not, controlling the floor-cleaning robot to move by one unit length in a second direction perpendicular to the first direction and determining whether the current location of the floor-cleaning robot is the secondary selectable area to be cleaned, wherein
• if not, controlling the floor-cleaning robot to move by two unit lengths in a third direction perpendicular to the second direction and opposite to the first direction and determining whether the current location of the floor-cleaning robot is the secondary selectable area to be cleaned, wherein
• if not, controlling the floor-cleaning robot to move by two unit lengths in a fourth direction perpendicular to the third direction and opposite to the second direction and determining whether the current location of the floor-cleaning robot is the secondary selectable area to be cleaned;
• and
• executing a cleaning operation in the secondary selectable area to be cleaned if the current location of the floor-cleaning robot is the secondary selectable area to be cleaned.
