摘要： An area partitioning method, a partition cleaning method and a robot are provided. The area partitioning method includes: sequentially determining, according to a preset priority order, whether each of candidate directions of a current partition can satisfy a creation condition; creating, when one of the candidate directions satisfies the creation condition, a new partition in the candidate direction satisfying the creation condition; and ending area partitioning when none of the candidate directions satisfies the creation condition. The method can improve the working efficiency of the cleaning robot and avoid the occurrence of random cleaning, which leads to good use experience and has a good application prospect.
