Abstract
A vacuum cleaner and a method for controlling the motor power of a vacuum cleaner are disclosed. The vacuum cleaner comprises an electric motor and an electric power supply for providing electric power to the electric motor. Furthermore, a voltage measuring means for measuring a motor voltage over the electric motor and a current measuring means for measuring a motor current flowing through the electric motor are provided. The vacuum cleaner further comprises a control means for controlling, based on the measured voltage and the measured current, the electric power provided to the electric motor from the electric power supply towards a target motor power value.
