A vacuum cleaner includes a drive unit having a maximum input power and a drive unit operating device configured to operate the drive unit below the maximum input power. The drive unit operating device includes a regulating unit configured to regulate an actual input power of the drive unit within a first operating range in which an input power is above a predefinable upper limit. The regulating unit is operable to detect a controlled variable including the actual input power and/or a measure of the actual input power, compare the actual input power to a reference variable including the predefinable upper limit and/or a measure of the predefinable upper limit, and influence the actual input power of the drive unit so as to conform the actual input power of the drive unit to the reference variable. |
