LG CordZero A925
The CordZero A925 is LG's mid-priced flagship stick vacuum, and it earns the highest overall score in our catalog. The argument is balance: a swappable dual-battery system rated up to 120 minutes, a genuinely light 5.9 lb body, and sealed HEPA filtration, all at $400. It doesn't chase Dyson's headline suction numbers — LG doesn't even publish one — but it out-scores every premium Dyson here at less than half the price.

- solid Suction (7/10)
Habilytics Score
LG publishes no Air Watt or kPa rating for the A925, so this score rests on tested pickup rather than a spec sheet — and because AW and kPa measure different things and can't be compared brand-to-brand, a missing number is less damning than it sounds. In practice it handles carpet and hard floors confidently, though it trails Dyson's top detect models on dense, deep-pile carpet.
The headline 120 minutes comes from LG's two swappable batteries running in the lowest eco mode with a non-powered tool; switch to Max with the motorized brush and each battery drains in roughly 8-10 minutes, so plan for real high-power cleaning in the ~15-20 minute range before you swap. Even so, carrying a second charged battery gives it the longest usable runtime in this catalog.
At 5.9 lb it's among the lightest full-size stick vacs here — over 2 lb under the 8.3 lb Dyson Gen5outsize and nearly 3 lb under the 8.9 lb Shark Stratos — which is what keeps overhead and stair cleaning from becoming a workout. Balance is good, though the weight creeps up slightly with both batteries and the full wand attached.

The runtime-to-weight balance is the real draw
Most stick vacuums force a choice: long runtime or a light body. The A925 sidesteps it. Two removable batteries let you vacuum a whole floor, swap in seconds, and keep going — up to a rated 120 minutes in eco — without hunting for an outlet mid-clean. And it does this at 5.9 lb, light enough that reaching overhead or working up a staircase doesn't punish your wrist. Sealed HEPA filtration rounds it out, trapping fine dust and allergens instead of leaking them back into the room — a real benefit in pet and allergy homes.
What you give up
Two honest caveats. First, LG publishes no suction rating, so you can't line the A925 up against a Dyson's Air Watts on paper — you're trusting tested performance, and on dense carpet it isn't quite at the level of Dyson's flagship detect models. Second, the 120-minute figure is best-case eco mode; switch to Max with the powered brush and each battery drains in roughly 8-10 minutes. Note too that the A925's dock only charges — you empty the bin by hand. The near-identical A937 adds auto-empty for $200 more.
Value at $400
At $400 the A925 is the value play. It shares its exact scores with the $600 A937 Auto-Empty — same suction, runtime, and handling — so the only thing the extra $200 buys there is not emptying the bin yourself. Look up-market and the math gets starker: the $950 Dyson Gen5outsize and Gen5detect both score lower overall, weighed down by 8-plus-lb bodies, and the $750 V15 Detect Plus lands well behind on runtime. The A925 delivers the catalog's best all-around result for the least money among serious contenders.
Who it's for / who it's not
Who it's for
- Whole-house cleaners who want to swap in a second charged battery rather than stop and recharge mid-session
- Anyone sensitive to vacuum weight — 5.9 lb keeps stairs, overhead reach, and long sessions manageable
- Pet and allergy households that need sealed HEPA to actually trap fine dust instead of recirculating it
- Shoppers who want near-flagship all-around performance without paying Dyson's $750-$950 premium
- People happy to empty the bin by hand to save $200 over the auto-empty A937
Who it's not for
- Spec-sheet shoppers who need a published suction number to compare — LG doesn't provide an AW or kPa figure
- Anyone expecting the full 120 minutes on Max; real high-power cleaning is closer to 15-20 minutes before a battery swap
- Buyers who want hands-off emptying — this dock only charges, so step up to the A937 for auto-empty
- Deep-pile carpet households chasing maximum suction; Dyson's Gen5detect pulls noticeably harder
- Bargain hunters — at $400 it's mid-priced, not budget; a Levoit or Eureka costs far less if top performance isn't the priority
Alternatives in our catalog
Dyson V15 Detect Plus — $750
Pick the V15 Detect Plus if you want Dyson's laser dust detection and a published 240 AW suction figure, and you'll trade the A925's swappable long runtime for a single 60-minute battery at $350 more.
Head-to-head comparisonDyson Gen5detect — $950
Step up to the Gen5detect only if maximum published suction (280 AW) is the priority and you can live with a heavier 7.7 lb body and a $950 price — nearly two-and-a-half times the A925.
