You still need the stupid adapter that prevents the hoover from standing firmly on the floor. If you want to do it differently, you can fit a plug yourself. As the housing is insulated, this should not be a problem.
If you have an IQ of more than 50, you can get the idea of letting the plug hang out about 2 cm .... then the vacuum cleaner stands upright wonderfully because the adapter is no longer in the way - the power cable is flexible!
(at least with me ... ;) )
