Robot Vacuum Comparisons
Head-to-head and five-way comparisons of the premium robot vacuums we cover, based on manufacturer documentation.
Our comparisons put specifications side by side and explain which documented differences actually affect ownership — dock automation, obstacle-crossing hardware, maintenance, and what each product does not state. They are editorial analysis of manufacturer information, not lab results.
How we compare
- Sources first. Each figure comes from the manufacturer or the Amazon US listing, and each comparison says when a spec is not published.
- Specifications are not performance. A higher rated suction number or a longer feature list is not a measured cleaning advantage. We do not turn spec sheets into scores.
- Fit, not a single winner. Where a comparison names a better fit, it names the documented feature behind it and who benefits — see each article's limitations section.
- No fabricated data. No invented test results, prices, ratings, or availability. Check price and stock on the Amazon listing itself.
