“An additional benefit is the flexibility this offers customers as they can subscribe to additional functions or upgrade to washers with larger capacity. This is the first test in the world of this concept. I strongly believe that Functional Sales will spread to other areas and may change the way we look at appliances – and services.”  This, coupled with the fact that Electrolux’s best washing machines consume less than 1kWh (kilowatt/hour) and less than 40 litres of water per cycle, makes for a very impressive solution.
“This type of product to service shift could have significant effects on the way the product is designed. To suit these business models, companies will have to design their products with increased endurance, serviceability and refurbishment capability which, in turn, will reduce the products overall environmental impact. These business models may well spread to other areas and may change the way we design our appliances in the future.”
