I opened a Nilfisk Multi 20. Use a flatscrew driver to click the cover of the grip of the cleaner. Remove with a torque key the screw on the backside. Use the flatscrew driver to lift the powercord pedal on the front side perpendicular to the grip. It is clipped on the grip where it swings. Use the same torque key to remove the second screw. Finally remove the inlet cover by pulling it out.
