Amazon’s $1.7 billion deal to buy Roomba maker iRobot gets UK approval

British antitrust regulators have cleared Amazon’s purchase of robot vacuum maker iRobot. But the $1.7 billion deal still faces scrutiny in the United States and Europe. The U.K. regulators said Friday that they decided not to escalate an initial investigation because the deal would not result in a “substantial lessening of competition” within the United Kingdom. Amazon said it was pleased with the result and hopes for “similar decisions from other regulators soon.” Consumer groups have voiced concerns that Amazon’s purchase of Bedford, Massachusetts-based iRobot, which makes the popular Roomba robotic vacuum cleaners, would widen the e-commerce giant’s dominance in the smart home market.
