Your Roomba may be vacuuming up more than you think.

High-end models of Roomba, iRobot’s robotic vacuum, collect data as they clean, identifying the locations of your walls and furniture. This helps them avoid crashing into your couch, but it also creates a map of your home that iRobot could share with Amazon, Apple or Google.

That prospect stirred some alarm when Reuters quoted iRobot’s chief executive, Colin Angle, saying that a deal could come in the next two years. But iRobot disputed that account, saying in a statement on Tuesday: “We have not formed any plans to sell data.” Reuters issued a correction, saying Mr. Angle was hoping to share the maps free with customer consent, not sell them.

The confusion underscored that the frontier of smart home data and privacy can be a sensitive one. In the hands of a company like Amazon, Apple or Google, that data could fuel the growing product category of digital home assistants.

“When we think about ‘what is supposed to happen’ when I enter a room, everything depends on the room at a foundational level knowing what is in it,” an iRobot spokesman said in a written response to questions. “In order to ‘do the right thing’ when you say ‘turn on the lights,’ the room must know what lights it has to turn on. Same thing for music, TV, heat, blinds, the stove, coffee machines, fans, gaming consoles, smart picture frames or robot pets.”
