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.

Pros
-
Fine dust and small-debris pickup on hard floors tested well in controlled reviews.
-
Innovation was strongest around the auto-empty tower, which reviewers framed as unusual or bleeding-edge for stick vacuums.
-
Onboard storage was one of the tower’s best-liked features because tools are hidden, organized, and close at hand.
-
Versatility was strong overall because reviewers used it across mixed floors, quick cleans, attachments, handheld cleaning, and mopping.
-
The handheld conversion was useful for finer control, tight areas, cars, sofas, and stairs.
-
The low-profile floorhead helped reach under beds and furniture.
-
Tool changes were described as intuitive and easy, with attachments clicking on and off without much friction.
-
Ease of use was generally strong, though not enough to offset reliability and clogging complaints for dissatisfied customers.
-
Above-floor and upholstery cleaning were strong, with reviewers praising couch, fabric, tight-spot, and pet-hair pickup.
-
Cordless convenience was a clear positive, with users valuing the lack of cord for easier day-to-day cleaning.
-
Hair pickup from carpets was positive in testing, with long strands removed from the floor.
-
Packaging feedback was positive in the customer evidence that mentioned it.
-
Carpet pickup was strong overall, including high-pile, shag, and general carpet tests.
-
Noise feedback was mostly positive, with several tests and users calling it quiet or less annoying than rivals.
-
Under-furniture reach was good thanks to low-profile and lay-flat handling.
-
Handling was mostly positive: reviewers highlighted light wrist feel, maneuverability, tight-corner control, and low-to-ground movement.
-
Area-rug handling was positive where reviewers said flatter rugs and fringe did not stall or jam the vacuum.
-
Cyclone performance was praised for helping sustain suction and keeping the pre-motor filter cleaner.
-
The self-emptying cycle was a standout feature when working, and some customers described it as essential.
-
Crevice pickup was a strength in test evidence, especially pulling sand or flour from hard-floor grooves.
-
Pet performance was polarized: several reviewers praised pet-fur pickup, but customer reviews repeatedly reported fur clogging and weaker results in homes with shedding pets.
-
Setup and unpacking were described as straightforward by customer reviewers.
-
Stair use was supported by lightweight handling and handheld-style cleaning, especially with smaller attachments.
-
The mop water controls were viewed as useful enough for choosing water output, but evidence was limited to basic water-level use.
-
The design was widely considered sleek and attractive, though one reviewer criticized the tower as heavy and clunky.
-
Emptying was highly polarized: many loved the dust-free auto-empty tower, but others found it slow, messy, or unreliable.
-
The tool bundle and attachments were generally valued, though some customers objected that certain accessories were sold separately.
-
Battery feedback was mixed: dual batteries were a major advantage, but turbo/runtime complaints appeared in tests and customer reviews.
-
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.
-
Maintenance was mixed: washable filters and easy parts helped, but clogs and frequent filter washing hurt ownership.
-
Low-pile carpet pickup was acceptable but reduced by larger cereal-type debris.
-
Runtime was mixed: dual batteries and medium-mode life helped, but turbo runtime and advertised claims disappointed some reviewers.
-
Hair-wrap resistance was mixed: some tests and users saw little wrap, while long-hair tests found major tangling.
-
Weight was mixed: several reviewers called it light, while customer reviews criticized the unit or head as heavy.
-
The compressor and bag system drew praise for extending capacity, but the small bin and bag cost/capacity were common caveats.
-
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.
-
Filtration was praised in some reviews, but one detailed test criticized the vacuum for failing dust containment.
-
The lock-on power button was praised, but the long-press process for maximum suction was criticized.
-
Mopping was mostly secondary: useful for light spot cleaning, but several users found it unimpressive or gimmicky.
Cons
-
Build quality evidence was mixed-to-negative: some saw premium construction, while customers reported weak plastic, broken tabs, and poor build quality.
-
Stuck resistance was mixed: it handled flatter rugs well, but customer reviews reported the vacuum getting stuck in the base station.
-
Smart and app features were not a major selling point; reviewers often called the app unnecessary or unreliable.
-
Storage was a tradeoff: the tower hides tools and can be freestanding, but several reviewers found it large or space-hungry.
-
Comparative performance was mixed: LG impressed in some user comparisons but lagged behind Dyson, Samsung, or Tineco in several tests and reviews.
-
Value was mixed: some reviewers called it worth the cost, but many felt the high price amplified missing features, failures, and repair hassles.

Ownership costs were a mild concern because bags and refill accessories were described as expensive or extra-cost items.
-
The liquid system was limited: reviewers noted water-only use and customers criticized the mop attachment when it failed or performed poorly.
-
Small-space suitability was weak because the tower needs side clearance and loses usefulness in tight slots.
-
Floorhead design was a common flaw, especially the low or poorly designed head that pushed larger debris instead of taking it in.
-
The missing headlight/LED feature was a recurring disappointment for customers.
-
Clogging was one of the clearest weaknesses, especially with cereal, fur, fluff, and narrow intake paths.

-
Heavy-duty suitability was weak for pet-heavy or kid-heavy homes because customers reported clogs, weak pickup, and the need to use other tools.

-
Dock and auto-empty reliability was a significant concern in customer reviews, especially base failures within months.
-
Hair-channel clogging was a clear pet-home problem, with fur getting stuck and requiring manual clearing.
-
Kid-friendliness was poor in evidence involving playdoh and larger household debris that still required broom-and-dustpan cleanup.
-

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.
