I'll grant that the ones using RGB cameras for SLAM have potential for exfiltrating information, but floor plans are literally public record. What value could that possibly have?
You can probably tell roughly number (and size) of sofa, chairs, tables, shelving units in each unit. Amount of carpet vs floor space. Total floor space.
That lets you build a dataset of these numbers correlated with all the other things Amazon knows about you. Then target you for ads.
Maybe, it notices that your coffee table is smaller than average than other similar people/apartments. They also know you have previously bought dark colored fake wood furniture before. So they advertise dark colored coffee tables to you, in the price range you would be able to afford.
I would be more concerned about this scenario if Amazon was also capable of discovering that because I purchased 1 door mat, does not mean that I want acquire a hoard of door mats, for my house made entirely of exterior doors.
Floor plans aren't public record, only a rough outline of building size. Go pull up your county's record of your house. At most, you'll get a box diagram showing sizes of different sections of your house, but nothing to indicate the actual layout of anything. These robot vacuums collect much more detailed information than that on millions of houses.
Even where they are public record, there are often limits. San Francisco limits you to six requests per day, costs $0.10 per page, and must be applied in person or via mail.
you mean basically the exact same information that you can get by going to an assessors website or office (in the USA anyway), and looking at the property record card they publish when setting your tax rates? Not to mention when you apply for a building permit, with plans - that all becomes public information.
The comment said "transcribe the floor plan", and this distinction is relevant because there are multiple options for robot vacuum cleaners without cameras.
