LG CordZero A925 vs Dyson V15 Detect Plus: Where the Extra $350 Goes
Both are do-it-all cordless sticks with a motorized pet tool, an anti-tangle brush, and fully sealed HEPA filtration — so shoppers usually land here torn between Dyson's name and headline suction figure and the LG's lower price. On paper the Dyson looks like the flagship. The scores tell a more complicated story, and most of it comes down to runtime, weight, and what you actually get for $750.
| LG CordZero A925 | Dyson V15 Detect Plus | |
|---|---|---|
| Overall score | 7.7/10 | 5.7/10 |
| Suction | 7/10 | 7/10 |
| Runtime | 9/10 | 4/10 |
| Handling | 7/10 | 6/10 |
| Suction (advertised) | not published | 240 AW |
| Max runtime | 120 min | 60 min |
| Weight | 5.9 lb | 6.8 lb |
| Filtration | Sealed HEPA | Sealed HEPA |
| Dock | Charging dock | Freestanding / wall mount (no dock) |
| Typical price | $400 | $750 |
Suction: one number published, one not — same score
Dyson publishes 240 air watts; LG publishes no suction figure at all. That gap looks decisive until you notice the engine scores both at 7/10. Air watts (Dyson) and kPa (most rivals) measure different things, so an AW number never proves more real-world pickup than a brand that reports differently — or, here, reports nothing. On carpet and hard floor the two clean comparably. Dyson's spec buys brand confidence and its dust-detection readout, not measurably stronger suction than the cheaper LG.
Runtime and weight: where the scores split
Here the engine diverges hard: LG runtime 9/10, Dyson 4/10. Both quoted figures — LG's 120 minutes, Dyson's 60 — are eco-mode, non-motorized-tool numbers; switch to Boost with the powered brush and each drops to single-digit minutes. The difference is that the LG carries swappable batteries to extend a session, while the Dyson runs down and needs a recharge. Weight compounds it: 5.9 lb versus 6.8 lb (handling 7 vs 6). That 0.9 lb is felt on stairs and overhead.
Filtration ties; dock and price don't
Filtration is a genuine wash — both seal HEPA, so allergy buyers can stop comparing there. The split returns on storage and money. The LG parks in a freestanding charging dock; the Dyson ships without one, so it lives on a wall mount you drill in or leans in a corner. Then the price: $400 versus $750. The cheaper vacuum posts the higher overall score (7.7 vs 5.7). You pay $350 more for the Dyson name and readout, and give up runtime, a dock, and a pound of reach.
Verdict
For almost everyone cross-shopping these, the LG CordZero A925 is the smarter buy: it matches the Dyson on the engine's suction score, runs far longer, weighs less, docks itself, and costs $350 less — hence the 7.7 vs 5.7 overall. Pick the Dyson V15 Detect Plus only if you specifically want its dust-detection readout and published suction spec, clean smaller spaces where short runtime is a non-issue, and don't mind wall-mounting. It's the pricier, heavier tool that the numbers here don't reward.
