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 Gen5detect
Of the 12 expert sources, 11 tested the Gen5detect hands-on, and nearly all praise its suction, sealed HEPA filtration and dust-revealing laser head. Two reviewers call it the best cordless vacuum they've tested. Among 529 owner comments, 46% praise suction. The two big caveats are consistent: 8 of 11 hands-on reviewers and 23% of owners find it heavy, and almost every reviewer flags the roughly $950 price. Several reviewers say the V15 Detect or cheaper rivals clean nearly as well. Reliability is the weaker spot (score 59, failure mentions in 17% of owner comments, 6% reporting it broke or died), and the battery runtime claims vary widely in real use. The QVC rating of 3.08 stars rests on only 12 reviews and is too thin to weigh heavily.
