Know before you buy
The V15 Detect's 7.61 score is driven almost entirely by safety (79.8% weight). It delivers the same sealed-HEPA 14 profile as the $1,050 Gen5detect at $380 — the core safety spec is identical. The material transparency gaps (filter chemistry, body BPA status) are real but category-wide. At $380 with the lowest annual TCO in the Dyson lineup (~$101/year), this is the best safety-to-value ratio in the cordless vacuum category.

You want whole-machine sealed HEPA 14 filtration — not just a HEPA filter — and want independent verification that no dirty air bypasses the filter at chassis seal points.
You're considering the Gen5detect but find it hard to justify $670 more for 10 extra minutes of runtime and marginally higher filtration capture (99.99% vs 99.97%).
Your home is under 2,000 sq ft and 40 minutes of runtime covers your cleaning session comfortably.
You want the largest dustbin in the category (0.77L) with a real-time particle sensor that confirms cleaning effectiveness as you go.
Your home is over 2,000 sq ft and you need 50–60 minutes of continuous runtime without a mid-session recharge.
You want a user-replaceable battery for long-term ownership — the Miele Triflex HX2 offers field-swappable battery packs the V15 does not.
You need the vacuum to self-empty into a dock — the Samsung Bespoke Jet's Clean Station does this; the V15 Detect does not.

In this Cordless Vacuum showdown, Miele takes the lead with a score of 8.2/10 vs Dyson's 7.6/10. Miele excels in overall performance, though Dyson may still be right for specific use cases.

Two strong Cordless Vacuum options compared. Samsung and Dyson both perform well with different strengths, so the right pick depends on your specific priorities.
The Dyson V15 Detect Absolute Cordless Vacuum was graded against the same cordless vacuum-specific rubric we apply to every product in this category — no brand-by-brand exceptions, no sponsored placements, no affiliate-weighted scores. The verdict above came from three pillars: safety (materials, certifications, recall history, chemical exposure pathways), efficacy (independent testing data, verified performance specs, real-world usage durability), and usability (ergonomics, cleaning, noise, parts availability over time). Every point deduction has a citation behind it. Every claim links back to a primary source. Nothing is hidden behind opaque badges.
What separates this from a typical cordless vacuum review elsewhere on the web: we don't accept sponsorships, paid placements, or rev-share-weighted rankings. The brand of the Dyson V15 Detect Absolute Cordless Vacuumcannot pay to move up the list. The score is logic-driven (a weighted formula across safety, efficacy, and usability), not opinion-driven, so an editor's personal preference cannot override the evidence. When two products in this category are within a point of each other, the right tie-breaker is whichever pillar matters most to your household — not whichever one ranks first.
A high safety score on the Dyson V15 Detect Absolute Cordless Vacuumdoesn't automatically mean “buy this.” A cordless vacuumthat's genuinely safe but loses points on efficacy may still be the wrong fit if performance is what you actually need. Conversely, a cordless vacuumthat's usability-strong but safety-flagged probably isn't the right call for a child with a known sensitivity. The score is the start of the decision, not the end.
R3 is not a medical, legal, or financial advisor. This review is general consumer-safety reporting, not personalized health guidance. If a safety concern on this page intersects with a specific allergy, sensitivity, or medical condition in your household, talk to your pediatrician or a board-certified specialist — they can weigh the evidence against your family's situation in a way no review can. We'll update this page when credible new evidence changes the picture (a recall, a new lab certification, a meaningful product redesign); the last-updated date in the byline is the source of truth on how current this analysis is.
