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 V12 Detect Slim
Seven of 8 expert sources tested the V12 Detect Slim hands-on, and they broadly agree it is a light, maneuverable vacuum that excels on hard floors, with an expert score of 81. Owners are positive too (owner score 84 from 507 comments): 45% praise the light weight and 36% the suction, while 16% complain about the small bin. Reliability is the weak spot, scoring 58, with 17% of owner comments mentioning failures and 5% describing a unit that broke or died. Retail ratings are strong overall (87 from 33,118 votes, with 21,772 five-star ratings), but smaller retailer listings average only 3.79 stars across 126 ratings, and battery opinions are split almost evenly (12% negative vs 11% positive).
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.
