It seems Roomba vacuums aren't the only robots scoring strong sales success for iRobot (NASDAQ:IRBT) abroad.

On Tuesday, Bedford, Mass.-based iRobot announced that it's just inked contracts worth $7.2 million to deliver its iRobot 510 PackBot military robot to Brazil. The contracts, which include both robots, spare parts, and associated equipment, will be delivered by December.

Brazil, which will be hosting the FIFA World Cup soccer tournament in 2014, is buying the PackBots in preparation for the event. Among other uses, the PackBot is often utilized for bomb disposal.

In a press release, iRobot noted that it has already delivered more than 5,000 such robots to military and civil defense forces worldwide. Most of these sales, of course, have been to the U.S. military. But the company has disclosed in past announcements that its PackBots are in use in at least 30 countries worldwide.
