Electrolux will have a much bigger presence in the United States after its purchase of General Electric’s U.S. appliance unit. Though one of the world’s largest appliance manufacturers, Electrolux is known in the United States mainly as the maker of elite vacuum cleaners and high-efficiency refrigerators and freezers. Adding the wide range of GE appliances will give Electrolux a much broader presence in the U.S. market, possibly eventually making it the leading manufacturer of home appliances.
