Vacuum cleaners and methods of controlling a motor driven by a battery source in a vacuum cleaner. The vacuum cleaner has a motor, a battery source for providing power to the motor, a voltage measuring unit for measuring a voltage over the motor, and a current measuring unit for measuring a current flowing through the motor. Further, the vacuum cleaner comprises a control unit for controlling, based on the measured voltage and/or 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, and to gradually decrease the power provided to the motor after the time period ends.

The present invention provides, in one embodiment, a vacuum cleaner nozzle comprising a nozzle body (); a suction plate () having an elongated suction inlet (), wherein the suction plate () is pivotally connected to the nozzle body () about a first pivot axis (A), which first pivot axis (A) extends parallel to the elongated direction of the suction inlet (); a nozzle outlet device () having, at a first end thereof, a tubular opening (), which tubular opening is matable with a tubular component () of a vacuum cleaner; and flexible hose () which is arranged to interconnect the suction plate () with the nozzle outlet device () such that the suction inlet () is in fluid communication with the tubular opening () of the nozzle outlet device (). The nozzle outlet device () is connected to the nozzle body () by means of a link element () comprising a forked first end and a second end, wherein the flexible hose () extends within the forked first end of the link element (), the forked first end () of the link element () is pivotally connected to the nozzle body () on either side of the flexible hose () about a second pivot axis (B), which second pivot axis (B) is parallel with the first pivot axis (A), and the second end () of the link element () is connected to a second end of the nozzle outlet device () about a third pivot axis (C), which third pivot axis (C) is perpendicular to the first and second pivot axes (A, B) and to an axis (D) passing through the first and second ends of the link element ().
