According to US government, women spend 16 minutes a day, on average, doing laundry, and men spend 4 minutes on average. That's over a 100 hours a year for women, so yes, there is probably a lot of demand for a technology that makes this faster.
How does one justify $600+ on saving 16 min a day? How does one sell this to any consumer with a >$100,000 income to a household?
