The company announced a series of lawsuits on Monday targeting Hoover, Black & Decker, Bobsweep and Bissell Homecare, according to the Boston Globe. The Massachusetts-based manufacturer of the popular Roomba robot vacuum cleaners accused its rivals of infringing patents it owns detailing technology and designs for autonomous floor-cleaning bots.
The company has been selling robot vacuum cleaners under the Roomba brand since 2002, with Hoover and Black & Decker only unveiling their rival products in 2016 and 2017, respectively.
"The filing of this litigation signals our commitment to protecting our investments," said iRobot spokesman James Baussmann in a statement to the Globe. "iRobot will not stand by while others offer products that infringe on our intellectual property."
Hoover and Black & Decker did not respond to requests for comment.
