Abstract: A floor types identifying device for use in a vacuum cleaner is disclosed, and comprises a current sensing unit coupled and a processing and controlling module. When a suction head is moved, a driving current of a roller brush driving motor is detected by the current sensing unit, such that the processing and controlling module judges that the suction head is moved on a specific floor that has a hard surface, a short-pile-carpeted surface or a long-pile-carpeted surface according to a variation of the driving current. Therefore, for a vacuum cleaner that is integrated with the floor types identifying device of the present invention, both suction power of the vacuum cleaner and driving power of the roller driving motor can be properly adjusted in response to the floor's surficial material type.
