A vacuum cleaner for cleaning floors or carpets, having a suction mouth (6), a base plate (5), which encloses the suction mouth (6), and a suction line, electrostatic charging of parts of the vacuum cleaner being provided in order to assist the dust uptake. In order advantageously to provide the vacuum cleaner with the dust uptake being assisted by electrostatic charging, the base plate (5) is electrostatically charged, and the electrostatic charging is carried out by a separate generator (8) provided in the vacuum cleaner.
