We can drop the word 'cleaner' in England. Also you often hear 'hoover' from the previously nearly universal brand Hoover, though now I think more people use Dyson branded cleaners but whilst we may refer to tha machine as 'the dyson' if we own one we wouldn't say 'I am going to dyson the room.' Folks say 'I will vacuum the room' or 'hoover the room' regardless of brand.
To note, Americans do not use Hoover as a verb. We also drop the word 'cleaner' sometimes in the USA.
And shouldn't it be "... is not working" since otherwise it sounds as if the malfunction is inborn or permanent?
