Amazon.com Inc.’s $1.65 billion planned takeover of iRobot Corp., maker of the Roomba vacuum, is facing a European Union merger review, with a provisional deadline set for July 6.

A new case file on the European Commission’s website said the companies sought formal approval from the EU’s merger regulators. The deal is also being probed in the U.K., where the Competition and Markets Authority will decide by June 16 whether to refer it to an in-depth investigation.

Seattle-based Amazon has come a long way as a hardware player since a failed foray into smartphones a few years ago, working diligently to place the Alexa voice software and Echo smart speakers at the center of the burgeoning market for smart-home gadgets. iRobot gives Amazon a household name in home cleaning gadgets that may give it a leg up over its own designs. Amazon’s own household robot, called the Astro, is still in a limited rollout two years on from its creation. 

Foxglove, a London-based tech advocacy group, earlier this year urged the EU to investigate and block the planned transaction, expressing “grave concerns” that the deal would increase Amazon’s access to data on users’ homes.
