How we score
Every robot gets an overall score out of 100 plus a breakdown by criterion. Our scores are independent — no advertiser can buy or sway them. Here's exactly how it works.
1. We gather the data
For each robot we collect manufacturer specs, real retailer prices and user feedback. Prices refresh automatically so they stay current.
2. We score each criterion
Specs are converted to 0–100 scores using calibrated scales that are consistent across the whole category — suction, navigation, battery, quietness, features and value for a vacuum, for example. The same scale applies to every model, so the scores are comparable.
3. We compute the overall score
The overall score sums up how the robot performs within its category. A model is never judged against a different category — a pool cleaner and a vacuum don't share criteria.
4. We keep it current
As prices move and new models launch, scores and rankings recalculate. Our best-of guides reflect the market as it is now, not a frozen snapshot.
