He succeeded again. Having fulfilled his first contract, Mr. Wenner-Gren returned to Lux with the Model II, a vacuum cleaner that weighed only 9 kilos and cost half the price of the Model I.
Convinced of the sales potential of the Model II, he tried to persuade Lux to manufacture the machine on a larger scale. Once again, his request was granted. It was granted on the condition that Mr. Wenner-Gren would get orders for 5,000 vacuum cleaners – ten times the yearly turnover guaranteed in his original contract – then Lux would invest in mass production.
He returned to his colleagues in Hamburg and offered them the sole right to sell his Lux II vacuum in Germany. Impressed with the machine and certain of its saleability, they immediately wrote an order for 5,000 machines.
