How we reached each verdictThe numbers behind each model's score
Dreame Z30
Three of the 4 expert sources tested the Dreame Z30 hands-on, and all 3 praise its cleaning, accessories and value against Dyson. The main concern is reliability. It scores 34 on reliability, 26% of owner comments mention some kind of failure, and 8% specifically say it broke or died. Battery life is genuinely contested: 16% of owners praise the battery and 14% criticize it, and Tom's Guide measured only 30-40 minutes in auto mode against the claimed 90. The expert evidence is fairly thin, because Consumer Reports' verdict is paywalled and only 3 sources published scores, but the owner base is large, with 338 comments, 314 of them first-hand.
Dyson V15 Detect
All 10 hands-on expert reviewers rate the V15 Detect a strong cleaner, and 42% of 566 owner comments praise its suction, so the core verdict is well supported. Its laser dust-revealing head wins over 8 of 10 reviewers, though Consumer Reports calls it of limited value. The recurring catches are price, cited by 6 reviewers, and a hold-down trigger with no lock, flagged by 5. Durability is the thinner part of the evidence: reliability scores 71, 12% of owner comments mention failures, and only one reviewer reports long-term use, nearly two years, with no performance drop.
