The Morning After: Is the Roomba an endangered species?

The company behind Roomba robovacs told investors earlier this week that revenue was substantially down and it's struggling to pay its debts. Amazon was briefly tapped to acquire the robot company iRobot, but the threat of a European Commission investigation led to the retailer terminating the deal -- apparently happy enough to pay off the 94 million termination fee. That, however, isn't enough to tackle the 200 million loan iRobot took out to survive long enough for Amazon to come to the rescue. It's extra rough when the company announced, just the week before, a bunch of new models, including a new Roomba that can compact debris and dust, so it only needs to be emptied every few weeks. At the same time, rival robot vacuum cleaners are getting more versatile, more complicated and more intriguing.
