Abstract

A charging control method, a non-transitory computer-readable storage medium, and a cleaning robot are provided. The method includes: detecting a charging status of the cleaning robot; in response to detecting that the cleaning robot is being charged, braking and locking the cleaning robot; monitoring a preset unlocking trigger operation, the preset unlocking trigger operation includes at least one of: rotation of the driving wheel under action of an external force, the cleaning robot completing charging, or the cleaning robot receiving an instruction for indicating to start a cleaning mode; in response to monitoring the preset unlocking trigger operation, unlocking the driving wheel; where monitoring the preset unlocking trigger operation includes: monitoring a status of the driving wheel; and in response to monitoring that the driving wheel rotates, determining that the unlocking trigger operation is detected.
