Every product reviewed on Hoomerly receives a single score out of 10. That number is our own — it is not aggregated from third-party sources, not pulled from Amazon ratings, and not borrowed from other review sites. It reflects the judgment of the contributor who covered that product, based on how well it performs the job it is actually sold to do.

One Score, Not a Breakdown

We assign a single overall score rather than separate sub-scores for individual criteria. The reason is straightforward: a product that scores 9 on suction and 4 on mopping is not a 6.5 overall — it depends entirely on what you are buying it for. A single number that reflects real-world usefulness is more honest than an average that can obscure a critical weakness or inflate a product with one standout feature.

The score represents our answer to one question: how well does this product do what most people who buy it actually need it to do?

What Goes Into the Score

The criteria we weigh vary by category because different products serve fundamentally different purposes. A robot vacuum is scored on different factors than a lawn mower or an air purifier. What stays consistent across all categories is the underlying framework:

  • Core performance — Does it do its primary job well? This carries the most weight in every score. A robot vacuum that maps beautifully but cleans poorly does not score well.
  • Real-world usability — Does it work the way a real household actually uses it, not just in ideal conditions? This includes setup, day-to-day operation, and whether it requires more management than it should.
  • Durability and reliability — Does it hold up over time? We factor in reported failure patterns, build quality, and whether the product performs consistently across multiple uses, not just on the first run.
  • Value at the price — Does what it delivers justify what it costs? A product priced at $300 is judged against what $300 should reasonably buy, not against a $1,000 flagship.
  • Significant weaknesses — A product with a critical flaw in a core function takes a meaningful penalty regardless of its strengths elsewhere. We do not average weaknesses away.

Who Assigns the Score

The contributor who writes the review assigns the score. Jessica Lane scores home appliances. Tom Woody scores outdoor power and garage equipment. Each contributor brings category-specific experience to their evaluation, which means the scoring criteria are calibrated to what actually matters in that product space — not applied generically across unrelated categories.

Scores are not committee decisions. The author who did the evaluation owns the number, and the reasoning behind it is in the review itself.

What the Numbers Mean

  • 9.0 – 10.0 — Exceptional. Does its job better than almost anything else at or near its price. Worth the cost for most buyers in its target use case.
  • 7.5 – 8.9 — Strong. Performs well across the criteria that matter, with trade-offs that are worth knowing but unlikely to be dealbreakers for the right buyer.
  • 6.0 – 7.4 — Decent. Gets the job done but has meaningful limitations. Usually a good fit for a specific type of buyer, not a general recommendation.
  • 4.5 – 5.9 — Below average. Underperforms in one or more core areas. Hard to recommend without significant caveats.
  • Below 4.5 — Not recommended. Included for comparison or context, but the performance or value does not hold up.

What the Score Does Not Reflect

Our score is not influenced by affiliate commission rates, brand relationships, or how popular a product is. A product with a large number of Amazon reviews does not score higher because of it. A product from a well-known brand does not get credit for its name. The score reflects performance and value, nothing else.

We also do not score based on specifications alone. A 20,000 Pa suction claim means nothing if the real-world airflow doesn’t back it up. Where independent lab data exists, we use it. Where it doesn’t, we rely on the contributor’s direct evaluation and note that clearly in the review.

Score Updates

Scores can change. If a product receives a significant firmware update that improves or degrades performance, if a known issue is resolved, or if a better-value alternative launches that shifts the competitive context, we revisit the score and update it. The review will note when a score has been revised and why.
