How we reached each verdictThe numbers behind each model's score
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.
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.
Dyson V8
All 6 expert reviewers used the V8 hands-on, and owner evidence is deep: 524 comments, 485 of them first-hand. Owners mostly like it. 40% praise its suction and 25% mention how light it is, but battery opinions split: 23% are positive and 17% are negative. 5 of 6 experts flag short runtime, especially in the roughly seven-minute max mode. 4 of 6 say it pushes larger debris on hard floors. The weak spot is reliability, which scores 42. 23% of owner comments mention failures and 6% say the unit broke or died. Consumer Reports' results are paywalled, so the expert view effectively rests on 5 detailed reviews.
