I believe the dishwasher has made the biggest impact on our society because everyone uses it nowadays. The dishwasher is convenient in so many ways. It could be done in less time then using hands; then you could attend to other business. And it works better by getting more stains off. Dishwashers aren't complicated at all, which makes it easy. The good thing about dishwashers is that new features will keep getting added, and new models will keep getting manufactured. Overall, I think the dishwasher is one of the greatest strongest inventions that has changed the lives of mankind.
