  1. Interestingly, Spangler was an asthmatic. When he turned 60 and was suffering severely from asthma, he grew frustrated at the tiring and dusty work of sweeping the carpet in the store where he worked. He suspected that the carpet sweeper he used on the job was the source of his cough. This is what motivated him to invent a practical vacuum cleaner.
