How the VS Score works — and what it can’t tell you
Every measurable spec is scored against the average of all the Robot Vacuums we track: matching the class average scores 50, clearly beating it climbs towards 100, and each spec counts according to an editorial weight that reflects real-world impact — a battery-capacity gap moves the score far more than a colour-options list. The quality bars on the spec cards above show where this model sits inside the full range for its class, and the overall VS Score rolls every weighted result into one number.
Unknown values are never estimated. A spec this product doesn’t report simply drops out of its scoring — it isn’t penalised with a guess — but a thinner spec sheet does mean a score built on fewer data points, which is why completeness is disclosed under About this data.
Most importantly: a spec-sheet lead is not the same as a better product. Megapixels, gigahertz and benchmark points describe capacity, not experience — image processing, software optimisation, thermals, haptics and ergonomics decide how a device actually feels, and no table captures reliability or long-term support quality. Treat the VS Score as a structured summary of what can be measured, not a substitute for your own priorities.
About this data
- Specifications are compiled from each manufacturer’s official spec sheet, cross-checked against trusted specification databases, and normalised into one schema so identical things are compared identically.
- Specifications last verified July 21, 2026.
- Data completeness: 29 of the 30 specs in this category are verified (97%). Anything we could not verify is shown as Unknown — never estimated — and is excluded from the score.
- Prices and availability come from live retailer feeds via our shopping partners and refresh throughout the day; a missing price means no partner currently lists the product, not that it is discontinued.
- Want the full picture? Our editorial guidelines explain how we research products, weight the scores and stay independent.
- Spotted an error in a spec? Tell us and we will correct the sheet.
