Individual Robot Vacuum Reviews, Scoped To What We Can Verify

It is a careful reading of everything a manufacturer publishes about one machine, cross-checked against what its competitors publish at the same price, with the gaps named. It is not a hands-on test, it is not an owner's report, and it will never pretend to be either.

Every review here carries a section headed what we did not verify. That section lists, specifically, the claims we could not check: whether the suction figure means anything in practice, whether the battery holds up after a year, whether the app is still supported in three. Those are real questions and we would rather name them than let a confident tone imply we answered them.

Only machines that are currently in stock and under the $300 ceiling. That sounds obvious and it is not how this category usually works - a large share of the 'best robot vacuum' pages ranking today recommend machines you cannot buy. When we checked the models we had planned to review, several were out of stock or discontinued, and those pages simply were not written.

The ceiling is enforced against live prices, not against our memory of what something cost. If a machine reviewed here rises above $300, the page says so at the top rather than quietly going out of date.

1. The verdict, in a paragraph, with the live price and a buy link at the top of the page rather than buried at the bottom.
2. Published specifications, each with the document it came from. Figures the manufacturer does not publish are marked 'Not published'.
3. What the specifications mean in a real home - the translation step, which is where a spec sheet stops being useful on its own.
4. What we did not verify - the explicit limits of this review.
5. Who should buy it and who should not, both stated plainly.
6. Alternatives at this price, linking to the band page and the relevant head-to-head.

Each review carries a score out of ten, computed from the published rubric. That score is editorial content and it stays on the page. It is deliberately not emitted as a review rating in the page's structured data, because that markup is a machine-readable assertion that this publisher tested the product and rated it. We did not, so we do not say we did - not in prose, and not in a format only a search engine reads.

It costs us the star ratings in search results that competitors show. That is the trade, and it is the correct one.
