Keeping things clean keeps Electrolux Home Products in business. The company makes and markets Beam, Eureka, and Electrolux brand central vacuum systems for boats, RVs, and residences (tubing is installed in the walls and the vacuumed debris is sent to a collection bin in the home's basement or garage). Its products are sold through certified dealers and online, serving customers in more than 50 countries worldwide. Owned by AB Electrolux, the vacuum maker was known as Beam Industries until 2007. The company's roots go back to WWII, when it manufactured washing machines, dishwashers, and scooters -- a product that became popular during the wartime gas-rationing period.
