if they are almost exactly same 2 vacuum cleaners except for mopping function, how can they score different points in parameters like Low-Pile Carpet , high-Pile Carpet or bare floor? its nonsense

Hello!

The verdict scores at the top of the review are usage scores, scores composed of several performance scores with weighted values. You can see what those weighted values are by clicking on the question mark beside the text. So, for example, Low-Pile Carpet is a hypothetical score that you might experience by using the product. It’s composed of 30% Low-Pile Carpet Pickup, 12% User Maintenance, 10% Portability, 10% Pet Hair Pickup, etc., with the performance scores shown later in the review.

In the case of the Dyson V15 Detect vs. the Dyson V15 Submarine, we did find minor differences in low-pile carpet pickup despite the vacuums being so similar. It’s a 0.5 point difference, which is minor and within the subjective margin of evaluation for a vacuum due to unit variance. If you take the other weighted scores - user maintenance: slightly lower, portability: slightly lower because it’s heavier, recurring cost: lower score since you have to replace the roller, noise: slightly lower score because it’s louder, the Submarine’s final weighted score is a bit lower.

We score this way based on user feedback. If you have any questions or suggestions to help us improve, please let us know.

Thank you.
