Sure, but most people don’t have a modern dishwasher. It’s an appliance that lasts 20 to 30 years ergo most people have old dishwashers that were manufactured decades ago.
Ya, but eventually the new tech will take over and we will be talking about very different things. Even if you just consider new builds, or hundreds of millions of Chinese buying their first dishwasher ever. Also, lots of utility districts offer incentives to upgrade to more efficient appliances.
