Elux is a much better transliteration than Yi Lai Ke Si.
I don't want to see it written as Electrolux because the company Electrolux sucks long noodles these days. It's not what it used to be, by far. The product quality is garbage. If you know what's good for you, never buy a product belonging to the Electrolux group (they own a whole lot of brands, so be careful).
