The present invention relates to vacuum cleaners and methods of controlling a motor driven by a battery source in a vacuum cleaner. For instance, a vacuum cleaner (1) is provided comprising a motor (2), a battery source (3) for providing power to the motor, a voltage measuring unit (4) for measuring a voltage over the motor, and a current measuring unit (5) for measuring a current flowing through the motor. Further, the vacuum cleaner comprises a control unit (6) for controlling, based on the measured voltage and the measured current, the power provided to the motor from the battery source to attain a target motor power value during a specified time period running from start-up of the motor. |
