In the 1960s, Electrolux marketed vacuum cleaners in the United Kingdom with the slogan "Nothing sucks like an Electrolux." The company chose the double entendre deliberately, since the informal American meaning of sucks was already well known in Britain.
Yes, in 1941 Electrolux developed the Charlton automatic rifle, based on the Lee-Enfield design. It was built to make up for shortages of the Bren light machine gun and the Lewis gun in the Home Guard.
