The contact, the cleaner body, and two contacts with the charger and two contacts with the floor suction tool are provided.

Thus, the rechargeable vacuum cleaner of the present invention
By connecting the storage batteries in series and charging them with one charger, even if the storage batteries are divided into one for the vacuum cleaner body and one for the floor suction tool, only one charger is required, and both storage batteries can be charged at once. In addition, since the charger is compact, the installation space is not required and the cost can be reduced.

According to a third aspect of the present invention, there is provided a rechargeable vacuum cleaner having a dust collecting chamber, a cleaner main body having an electric blower driven by a first storage battery, and a flexible hose connected to the cleaner main body. A floor suction device having an extension tube connected to the flexible hose, a rotating brush connected to the extension tube, and a motor for rotating the rotating brush; and a second power supply as a driving power source for the motor. In the vacuum cleaner provided with a storage battery, when the first storage battery and the second storage battery are connected in series to a charger and charged, and the vacuum cleaner main body is stored in a charging stand of the charger, When the contacts of the vacuum cleaner body are connected to the contacts of the charger and the floor suction device is stored in the stand,
The structure was such that the contacts of the floor suction tool were connected to the contacts of the cleaner body.

Thus, the rechargeable vacuum cleaner of the present invention
Just by placing the vacuum cleaner body and the floor suction device on the charging table mounting table, the charger and the storage battery of the vacuum cleaner body and the storage battery of the floor suction device can be automatically connected. Reliable and easy charging of the storage battery can be ensured.
