LG CordZero A937 Cordless Stick Vacuum Review
Bottom Line
Choose it for carpet, quick cordless cleaning, organized storage, and hands-off emptying. Skip it for heavy hard-floor debris, pet-fur clogging risk, tight storage slots, or if warranty support matters most.
Best for
Best for users who want a premium cordless stick vacuum with strong carpet pickup, organized attachment storage, dual batteries, and hands-off dust emptying for quick daily cleaning.
Not for
Not for buyers who mainly clean hard floors with larger debris, have heavy-shedding pets, need a compact storage slot, or want low-risk long-term reliability.
Verdict
The LG CordZero A937 earns its strongest praise as a convenient all-in-one stick vacuum: reviewers liked the cordless format, carpet pickup, quiet operation, hidden tool storage, swappable batteries, and the self-emptying tower when it works. The tradeoff is that the same evidence repeatedly exposes weak spots: larger debris on hard floors can push, scatter, or clog, pet fur can jam the intake or auto-empty path, and several customers reported base, battery, motor, or support failures. It feels premium and unusually convenient in positive reviews, but the high price makes the hard-floor and reliability complaints much harder to ignore.

Negative 1.5-2.419 (29%)
Pros highlights
-
Emptying was highly polarized: many loved the dust-free auto-empty tower, but others found it slow, messy, or unreliable.
-
Reviewers and tests split on raw suction: some found it excellent or surprisingly strong, while others measured only average airflow or said it was weak in real use.
-
Overall opinion was highly mixed: several reviewers loved or recommended it, while others refused to recommend it because of hard-floor, reliability, or support problems.
-
Carpet pickup was strong overall, including high-pile, shag, and general carpet tests.
-
Maintenance was mixed: washable filters and easy parts helped, but clogs and frequent filter washing hurt ownership.
-
The compressor and bag system drew praise for extending capacity, but the small bin and bag cost/capacity were common caveats.
Cons highlights
-
Large debris intake was one of the weakest areas, with cereal, Cheerios, and food pieces clogging, scattering, or getting pushed around.
-
Comparative performance was mixed: LG impressed in some user comparisons but lagged behind Dyson, Samsung, or Tineco in several tests and reviews.
-
Storage was a tradeoff: the tower hides tools and can be freestanding, but several reviewers found it large or space-hungry.
-
Smart and app features were not a major selling point; reviewers often called the app unnecessary or unreliable.

FAQ
Is the LG CordZero A937 good on carpet?
Yes, carpet performance was one of its strongest areas. Reviewers and tests praised pickup on carpet, including high-pile and shag examples.
How does it handle hard floors?
Hard-floor results were mixed. Fine dust and crevice pickup tested well, but larger debris like cereal, Cheerios, glitter, or food pieces was often pushed, scattered, or clogged.
Is the auto-empty tower worth it?
When it works, reviewers loved the cleaner, hands-off emptying and hidden tool storage. Customer reviews also reported base failures, dust spraying, incomplete emptying, and units getting stuck.
Is it a good vacuum for pet hair?
It can pick up pet hair very well, especially in positive tests and some customer homes. The downside is repeated customer evidence of fur clogging the intake or auto-empty path.
Does the battery last long?
The two-battery setup was praised because it extends usable cleaning time. Turbo mode and advertised runtime claims drew complaints, so runtime depends heavily on power mode and nozzle use.
Does it have a headlight?
Several customers complained about the missing headlight or dirt-revealing floorhead, especially because of the premium price.
