How many rugs does the average person have in their home? Is it in any relation to the amount and shape of furniture? If we shape our tables a certain way, are people more likely to buy our rugs to go with them? What's the average size of a rug in a person's home? etc

Interestingly enough, this isn't possible at the moment, but probably possible in the future. I own a (edit: 980) and they do actually detect when they're on a carpet/rug (they turn on a carpet mode that is basically just sucking twice as hard). However, there is no indication they're saving this data (the maps don't give any information of where Roomba thinks there's carpet, and there's always a delay in the carpet mode when it enters the carpet so its not learning that).

Its these kinds of things that lead me to sort of trust the CEO here with current products. Even after 2 months the map isn't very accurate and the user can manipulate the data (the map gives no indication between walls, the blockers it comes with, and closed doors).

Probably will keep close attention to see if they ever make any upgrades though.

How much free space is there in the user's home? Can we target them with furniture ads? If they have a lot of furniture, can we target them with reupholstery or furniture polish or other such maintenance ads?

Do they have a big home? Do they have a small home? I'm sure this is valuable for advertising reasons as well.

How often do they clean their home? If they're cleaning all the time, maybe we should target them with ads for professional cleaners. If they rarely clean their home, there's probably something of value that can be learned from that too.
