Abstract
A vacuum cleaner of protection class II is provided with a connection for a suction hose; a drive motor; at least one electrically non-conductive part; a feed line configured to feed static voltage; and a capacitor device provided with a capacitor group with at least one capacitor. For discharging static voltage, the electrically non-conductive part is electrically conductively connected via at least one contact element to the capacitor device. The feed line is connected to the at least one capacitor. The at least one capacitor outputs the voltage to an electrical power network when a certain charge quantity is exceeded. The at least one contact element can be the motor shaft of the drive motor.
