iRobot's new Roomba can empty itself - but it'll cost you almost $1,000

The robot vacuum now comes with an auto-emptying feature, wherein it attaches to a dock and any dirt or debris is sucked up into a reservoir that houses a large trash bag. This way, users don't have to worry about emptying their Roomba as often and, in turn, it becomes a more hands-free process. These features will come at a price, however. The i7 is priced at $950, making it the company's most expensive model to date. The dock also serves as a charging station for the i7 .
