LG CordZero A937 Auto-Empty vs Dyson Gen5 Detect Cordless Vacuum

The Dyson Gen5 Detect is the stronger deep cleaner: 300 W of suction, whole-machine HEPA, and a screen that tells you when a floor is actually clean. The LG CordZero A937 wins on run time and convenience, with up to 120 minutes per charge and a stand that empties the bin for you. Pick the LG for long, light sessions and hands-off emptying; pick the Dyson for carpets, embedded dust and the most thorough clean per pass.

  • Choose the LG CordZero A937 Auto-Empty if you want long run time, a lighter vacuum, and a stand that empties the bin so you rarely touch dust.
  • Choose the Dyson Gen5 Detect if you have carpets and pets and want the most suction, whole-machine HEPA, and a screen that confirms when a floor is clean.

What reviewers say

Dyson Gen5 Detect Cordless Vacuum

Owners rate the Gen5 Detect highly for suction and filtration, and the particle counter is widely seen as genuinely useful rather than a gimmick. Most complaints centre on weight, the small bin and short bursts of maximum power.

What people mention
  • SuctionPraisedOwners say it pulls more grit out of carpet than earlier cordless models and rivals at the same level.
  • WeightCriticisedMany find it tiring to hold high or for long sessions, especially on stairs.
  • Bin sizeCriticisedThe small bin fills quickly in big rooms, so owners empty it several times per clean.
  • FiltrationPraisedAllergy sufferers report less dust in the air and fewer symptoms after switching.

Questions and answers

Which is better for pet hair?
The Dyson Gen5 Detect. Its higher suction and de-tangling cleaner head pull more hair out of carpet, and whole-machine HEPA traps what it lifts. The LG handles pet hair well on hard floors and its auto-empty stand keeps hair out of your hands.
Which has longer battery life?
The LG CordZero A937, at up to 120 minutes versus up to 70 for the Dyson. Both figures are on the lowest power setting; expect far less at max suction.
Is the Dyson worth stepping up to?
If you have wall-to-wall carpet or allergy concerns, yes. The extra suction, whole-machine HEPA and cleaning screen give a more thorough clean. If you mostly clean hard floors and want long sessions, the LG is the better fit.
Which is easier to live with day to day?
The LG. It is lighter, charges faster and its stand empties the bin for you. The Dyson asks more of you: heavier, slower to charge, and you empty the bin by hand.
Do both convert to a handheld?
Yes. Both detach to a handheld for stairs and upholstery. The Dyson's wand also detaches to become a crevice tool, so you can switch mid-clean without hunting for an attachment.
Which is better on hardwood?
The LG is a solid hard-floor vacuum and lighter to push. The Dyson's Fluffy Optic head reveals fine dust on hard floors, which helps if you want proof the floor is clean.
