Amazon has signed an agreement to acquire iRobot, makers of Roomba robot vacuums.

The deal is valued at approximately $1.7 billion, and Amazon will acquire iRobot for $61 per share in an all-cash transaction.

iRobot has been designing robot vacuums since 2002, and it has sold millions of its popular Roomba vacuums. Earlier this year iRobot launched its latest iRobot OS, an AI-powered platform for its robot vacuums and mops. The iRobot OS is designed to differentiate Roomba products from competitors with additional software features and capabilities as the robot cleaning space gets increasingly competitive.
