The files

Four files, each dated from its own rows.

products.json
The home robots on this site, with the specs each maker states.
33 records, 77 KB. Newest date: Nov 2, 2026.
offers.json
Where each home robot is sold, with the price and stock on the day I checked.
72 records, 33 KB. Newest date: Nov 2, 2026.
humanoids.json
The humanoids with their own page on this site, with what each maker states. A tracker, not a buying guide.
20 records, 66 KB. Newest date: Nov 6, 2026.
changes.json
Every change I’ve published, oldest first, with the page that shows it.
65 records, 40 KB. Newest date: Oct 31, 2026.

They’re built with the site, so they match its pages. updated at the top of each file is the newest check date in its rows.

How to read them

The same rules hold in every file.

Joining the files: slug in products.json and humanoids.json matches robot_slug in offers.json and changes.json.
Prices: US dollars, the cart price before tax and coupon codes, on the day in checked. Only a row with offer_type “Robot” is a robot’s price. Bundles and extended warranties have their own rows.
Amazon: these rows have no price, because Amazon doesn’t allow showing a price I checked myself. The row gives the link.
“Not stated”: I looked and the maker doesn’t say.
Empty (null): no value on record. The field doesn’t apply to that kind of robot, or there’s no figure to give. The robot’s page has any detail.
Dates: YYYY-MM-DD, US Eastern.
Makers’ words: specs, safety guidance and delivery dates are what the maker says, on the day I read it. A delivery or pre-order date is the maker’s claim, not a fact.
Not ranked: robots are in order of their ID and changes in order of date. The order means nothing.

The files are under the CC BY 4.0 license. You can copy, share and build on them, commercially too, as long as you credit RoboHousehold and link to this page.

The license covers my records. Words in quotes are the maker’s and stay the maker’s.

Prices and stock change. Go by the date on each row, and check the seller’s page before you rely on one.

Found a wrong value?

Tell me the file, the robot and the field. I check it against the maker’s own page before changing anything, and if it was wrong, it goes on Corrections.
