Amazon faces hurdles to close iRobot deal

Amazon.com's deal to acquire iRobot has had it jumping through regulatory approval hoops in the U.S. and elsewhere for more than eight months. This is mainly due to the maker of the Roomba vacuum holding a 62 percent share of the robotic vacuum market. "The iRobot deal more naturally fits the profile of the things we know this FTC is concerned about," said Paul Gallant, policy analyst for TD Cowen.
