As shown in the first embodiment, the suction tool 100 includes a control unit 160 that controls the drive motor 150. Various electric circuits and the like are mounted on the control unit 160. The control unit 160 and the drive motor 150 are electrically connected.

In the present embodiment, the control unit 160 has a torque detection unit 161 that detects the torque applied to the drive motor 150. The torque detection unit 161 detects torque according to an electric signal from the drive motor 150. The function of the torque detection unit 161 may be realized by an external device of the control unit 160.

Further, in the present embodiment, the control unit 160 includes a motor control unit 162 that controls the rotation speed of the drive motor 150 according to the torque detected by the torque detection unit 161 described above.

The torque applied to the drive motor 150 varies depending on the type of the cleaning body 132 and the type of the surface to be cleaned. For example, the torque applied to the drive motor 150 differs between the case where cleaning is performed by the soft cleaning body 132 for wooden flooring and the case where cleaning is performed by the hard cleaning body 132 for carpet. When the wooden flooring is cleaned by the soft cleaning body 132 for the wooden flooring, it is preferable to reduce the rotation speed of the drive motor 150 in order to prevent damage. Further, when the carpet is cleaned by the hard cleaning body 132 for the carpet, it is preferable to increase the rotation speed of the drive motor 150 in order to scrape out the dust more strongly.

Further, for example, compared to the case where the soft cleaning body 132 for wooden flooring is correctly used to clean the wooden flooring, when the wooden flooring is cleaned by mistake with the hard cleaning body 132 for carpet. The torque applied to the drive motor 150 becomes high. In this case, it is preferable to reduce the rotation speed of the drive motor 150 in order to prevent the wooden flooring from being damaged by the hard cleaning body 132.

Further, the suction tool 100 may include, for example, a cleaning body detecting unit 170 that detects the type of the cleaning body 132 attached to the rotating shaft 131. For example, when using the vacuum cleaner 200, the user inputs information on the type of the cleaning body 132 attached to the rotating shaft 131 by the operation unit 270. The cleaning body detection unit 170 detects the type of the cleaning body 132 attached to the rotating shaft 131 according to the input information to the operation unit 270. The cleaning body detection unit 170 may be configured to be able to automatically detect the type of the cleaning body 132 without requiring an operation by the user. Then, the motor control unit 162 controls the rotation speed of the drive motor 150 according to the type of the cleaning body 132 detected by the cleaning body detecting unit 170. As a result, an appropriate operation is executed according to the type of the cleaning body 132 attached to the rotating shaft 131.

Further, the motor control unit 162 may control the rotation speed of the drive motor 150 according to both the detection result of the torque detection unit 161 and the detection result of the cleaning body detection unit 170. As a result, a more appropriate operation is executed according to the type of the cleaning body 132 attached to the rotating shaft 131 and the type of the surface to be cleaned. The functions of the torque detection unit 161 and the motor control unit 162 of the control unit 160 in this embodiment are realized by a device provided in the vacuum cleaner main body 210, for example, a control device for a vacuum cleaner that controls an electric blower 251 or the like.
