Abstract
Disclosed are a method and device for selecting a to-be-cleaned area. The method includes: obtaining to-be-cleaned secondary selectable area; controlling a floor-cleaning robot to move by one-unit length in first direction and determining whether the current location of floor-cleaning robot is to-be-cleaned secondary selectable area; if no, controlling the floor-cleaning robot to move by one-unit length in second direction and determining whether the current location of floor-cleaning robot is to-be-cleaned secondary selectable area; if no, controlling the floor-cleaning robot to move by two-unit lengths in third direction and determining whether the current location of floor-cleaning robot is to-be-cleaned secondary selectable area; if no, controlling the floor-cleaning robot to move by two-unit lengths in fourth direction and determining whether the current location of floor-cleaning robot is to-be-cleaned secondary selectable area; and executing cleaning operation in to-be-cleaned secondary selectable area if the current location of floor-cleaning robot is the same.
