It all started with a single vacuum. In the 1920s, Electrolux took off thanks to designer Gustaf Sahlin and his invention of the canister vacuum, which could clean floors more efficiently than other models and didn't produce tiny tornados in the living room. Much of Sahlin's original design has remained throughout the decades and continues in the company's current vacuum line, which has grown to include uprights and central vacuum systems. In 2003, the company entered the new millennium with even more products and a new name: Aerus Electrolux. The change in moniker reflects its expansion into new areas, including systems for water purification and air filtration.
