Compare LG CordZero A937 Cordless Stick Vacuum vs Shark Vertex Pro Cordless Vacuum Cleaner

Ease of use was generally strong, though not enough to offset reliability and clogging complaints for dissatisfied customers.

Ease of use is generally strong, driven by no head swapping, easy emptying, and smooth maneuvering, despite some resistance or weight caveats.

Kid-friendliness was poor in evidence involving playdoh and larger household debris that still required broom-and-dustpan cleanup.

Kid-friendliness has only one light positive mention, focused on the vacuum being cool enough that kids may like using it.

Onboard storage was one of the tower’s best-liked features because tools are hidden, organized, and close at hand.

Onboard tool storage is a weakness because one reviewer specifically found the lack of onboard storage frustrating.

Hard-floor hair pickup was weaker in customer evidence, particularly for dog fur on tile or wood floors.

Hard-floor hair pickup has limited but positive evidence from a reviewer impressed by the vacuum’s hair performance across test floors.

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.

Heavy-duty suitability has limited but positive evidence from a pet-heavy home reviewer who saw enough power for deeper cleaning.

Small-space suitability was weak because the tower needs side clearance and loses usefulness in tight slots.

Small-space suitability has limited but positive evidence from compact fold storage and short-space convenience.

Innovation was strongest around the auto-empty tower, which reviewers framed as unusual or bleeding-edge for stick vacuums.

Innovation versus competitors is mixed-to-negative because reviewers liked some Shark features but noted missing newer automation.

Large debris intake was one of the weakest areas, with cereal, Cheerios, and food pieces clogging, scattering, or getting pushed around.

Large-debris intake on hard floors is mostly strong, though one reviewer saw oats flicked around and another saw edge-related debris quirks.

Debris illumination was criticized because customers expected a headlight or dirt-revealing floorhead at this price.

Debris illumination is helpful overall, with floorhead lighting making dirt easier to see, though one reviewer found it only moderately helpful.

The missing headlight/LED feature was a recurring disappointment for customers.

LED headlights are helpful for visibility, although one reviewer found the white light less useful than Dyson-style green illumination.

Crevice pickup was a strength in test evidence, especially pulling sand or flour from hard-floor grooves.

Crevice and groove pickup has limited negative evidence, with one lab test requiring considerable effort and still missing debris.

Storage was a tradeoff: the tower hides tools and can be freestanding, but several reviewers found it large or space-hungry.

Storage is one of the clearest strengths, with repeated praise for the fold-over design and compact, stable storage posture.

Area-rug handling was positive where reviewers said flatter rugs and fringe did not stall or jam the vacuum.

Area-rug handling is mixed: shag performance was praised, but rugs, tassels, and deep pile could cause sticking.

Filtration was praised in some reviews, but one detailed test criticized the vacuum for failing dust containment.

Filtration and dust containment are a major strength, with multiple reviewers praising sealed HEPA performance and low particle escape.

Maintenance was mixed: washable filters and easy parts helped, but clogs and frequent filter washing hurt ownership.

Maintenance is mixed: washable and accessible parts help, but filter clogging, frequent washing, and hair removal were recurring concerns.

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.

Overall opinion is mostly positive, but not unanimous: many recommend it strongly, while one lab review does not recommend it due to filter clogging.

Hair-wrap resistance was mixed: some tests and users saw little wrap, while long-hair tests found major tangling.

Hair-wrap resistance is mostly strong, but not perfect: several reviewers praised anti-wrap performance while others found clumps or non-removable roller issues.

Clogging was one of the clearest weaknesses, especially with cereal, fur, fluff, and narrow intake paths.

Clogging prevention is a weakness in the lab review that found the pre-motor filter clogged easily with fine debris.

Carpet pickup was strong overall, including high-pile, shag, and general carpet tests.

High-pile carpet evidence is excellent, including a best-performance tie and a successful shag-carpet test.

Low-pile carpet pickup was acceptable but reduced by larger cereal-type debris.

Low-pile carpet pickup is strong in tests, with one review reporting 90% pickup and another saying most debris was collected.

Fine dust and small-debris pickup on hard floors tested well in controlled reviews.

Hard-floor fine-dust pickup is consistently strong, with multiple reviews describing clean hard floors and easy fine-debris pickup.

Weight was mixed: several reviewers called it light, while customer reviews criticized the unit or head as heavy.

Weight is one of the most repeated tradeoffs, praised as manageable by some but criticized in handheld, stair, or longer-use scenarios.

Stuck resistance was mixed: it handled flatter rugs well, but customer reviews reported the vacuum getting stuck in the base station.

Stuck resistance is a weakness on some rugs or deep-pile carpet, where reviewers reported sticking or catching.

Tool changes were described as intuitive and easy, with attachments clicking on and off without much friction.

Tool changes and configuration changes were described as simple, especially lift-away transitions and snap-in cleaning parts.

Handling was mostly positive: reviewers highlighted light wrist feel, maneuverability, tight-corner control, and low-to-ground movement.

Handling is widely praised, with reviewers highlighting responsive swivel, smooth steering, and easy maneuvering around obstacles.

Packaging feedback was positive in the customer evidence that mentioned it.

Packaging feedback is positive where discussed, with reviewers appreciating recyclable paper and cardboard packaging.

Hair-channel clogging was a clear pet-home problem, with fur getting stuck and requiring manual clearing.

Hair-removal channel issues are a recurring caveat where reviewers saw clumping or difficult detangling around non-removable parts.

The compressor and bag system drew praise for extending capacity, but the small bin and bag cost/capacity were common caveats.

Dust-bin feedback is mixed: some reviewers liked the larger or above-average capacity, while another found the bin compact and messy to empty.

Cordless convenience was a clear positive, with users valuing the lack of cord for easier day-to-day cleaning.

Cordless use is strongly valued for range, car cleaning, stairs, and freedom from cord limits.

Hair pickup from carpets was positive in testing, with long strands removed from the floor.

Carpet hair pickup is generally strong, with pet-hair carpet performance praised despite some clumping and cleanup caveats.

Under-furniture reach was good thanks to low-profile and lay-flat handling.

Under-furniture cleaning is widely praised thanks to the MultiFLEX/flexible wand, though one reviewer disliked the feel and low-appliance reach is limited.

Above-floor and upholstery cleaning were strong, with reviewers praising couch, fabric, tight-spot, and pet-hair pickup.

Above-floor and upholstery cleaning is generally good, helped by attachments, handheld conversion, and lift-away-style use.

The tool bundle and attachments were generally valued, though some customers objected that certain accessories were sold separately.

The tools are useful for common above-floor tasks, but coverage is uneven and some reviewers wanted better storage or a broader kit.

Runtime was mixed: dual batteries and medium-mode life helped, but turbo runtime and advertised claims disappointed some reviewers.

Runtime is mixed: low-power or two-battery use can be strong, but boost mode drains quickly and some reviewers wanted more battery life.

Emptying was highly polarized: many loved the dust-free auto-empty tower, but others found it slow, messy, or unreliable.

Emptying is mixed: several reviewers found it easy and low-contact, while one had trapped hair and messy manual removal.

Versatility was strong overall because reviewers used it across mixed floors, quick cleans, attachments, handheld cleaning, and mopping.

Versatility is one of the strongest themes, with reviewers repeatedly praising multi-surface cleaning and multiple configurations.

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.

Pet-related evidence is mostly positive for hair pickup and pet tools, with caveats around clumping and occasional manual cleanup.

Support and warranty feedback was strongly negative overall, with repeated complaints about slow repairs, poor communication, and unresolved failures.

Support evidence is limited but favorable, based on replacement parts availability and warranty coverage.

Value was mixed: some reviewers called it worth the cost, but many felt the high price amplified missing features, failures, and repair hassles.

Value is mixed-to-positive: several reviewers call it a strong mid-priced or good-value option, but others say newer or better alternatives exist.

Setup and unpacking were described as straightforward by customer reviewers.

Setup is consistently easy, with reviewers saying assembly is straightforward and the main parts click together logically.

Cyclone performance was praised for helping sustain suction and keeping the pre-motor filter cleaner.

Cyclone performance is a clear weakness in one lab review, which criticized the lack of multiple cyclones for fine-dust separation.

Noise feedback was mostly positive, with several tests and users calling it quiet or less annoying than rivals.

Noise is a drawback in the reviews that measured or discussed it, especially on boost or carpet settings.

Comparative performance was mixed: LG impressed in some user comparisons but lagged behind Dyson, Samsung, or Tineco in several tests and reviews.

Comparative performance is mixed: it wins on runtime or price in some comparisons, but one lab says better options exist.

Ownership costs were a mild concern because bags and refill accessories were described as expensive or extra-cost items.

Ownership-cost evidence is mixed: washable filters help, but one lab warned the filter may need frequent cleaning and replacement.

Stair use was supported by lightweight handling and handheld-style cleaning, especially with smaller attachments.

Stair cleaning is context-dependent: cordless reach helps, but the heavy cleaner head can make repeated lifting cumbersome.

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.

Reviewers generally found suction and pickup strong on floors, though one lab measured below-average raw airflow and another noted reduced suction versus top competitors.

Long-term durability was a major weakness in customer evidence, with reports of suction loss, motors dying, and units failing early.

Longevity evidence is limited but positive, centered on the long warranty coverage mentioned in one review.

Floorhead design was a common flaw, especially the low or poorly designed head that pushed larger debris instead of taking it in.

The DuoClean/dual-roll floorhead is a standout, repeatedly credited for strong pickup and compensating for lower measured power.

The low-profile floorhead helped reach under beds and furniture.

Low-profile reach is mixed-to-negative, with reviewers saying it can reach under some furniture but not under low appliances or far under furniture without reconfiguration.

Build quality evidence was mixed-to-negative: some saw premium construction, while customers reported weak plastic, broken tabs, and poor build quality.

Build-quality evidence is limited to one positive user-facing comment describing the vacuum as sturdy and well made.

The handheld conversion was useful for finer control, tight areas, cars, sofas, and stairs.

The handheld conversion is useful for above-floor work, but several reviewers found weight or balance limiting during longer handheld use.

The design was widely considered sleek and attractive, though one reviewer criticized the tower as heavy and clunky.

Design opinions are mixed but lean positive: reviewers liked the sleeker look in some models, while one found the styling clunky.

The lock-on power button was praised, but the long-press process for maximum suction was criticized.

Controls and displays are usually praised for battery readouts and easy mode changes, though one reviewer disliked the default Deep Clean reset.

Smart and app features were not a major selling point; reviewers often called the app unnecessary or unreliable.

Smart automation is a weakness because reviewers noted the lack of automatic suction or floor adjustment.

Battery feedback was mixed: dual batteries were a major advantage, but turbo/runtime complaints appeared in tests and customer reviews.

Battery and charging are generally positive because of removable or swappable batteries, though runtime depends heavily on mode.

Debris blowback/scatter was a problem on hard floors and with loose debris.

Edge and baseboard cleaning is good overall, though one test found parallel wall cleaning better than head-on approaches.

Mopping was mostly secondary: useful for light spot cleaning, but several users found it unimpressive or gimmicky.

The self-emptying cycle was a standout feature when working, and some customers described it as essential.

The obstruction shutoff behavior was criticized when users reported false obstruction errors or shutdowns during cleaning.

Medium-pile and deep carpet evidence is strong, including perfect or near-leading deep-clean results in several tests.

Floorhead seal evidence is mixed-to-negative, with good crevice pickup in one review but weaker seal concerns in others.

Odor control was a negative in customer evidence, with the auto-empty/dust-bag process described as producing an unacceptable smell.

Scratch resistance evidence was negative where small debris dragged along wood floors and scratched them.

The liquid system was limited: reviewers noted water-only use and customers criticized the mop attachment when it failed or performed poorly.

Mopping residue/streaking evidence was negative where customers said the mop moved dirty water around.

Surface-safety evidence is limited but positive, based on the soft roller’s gentle buffering action on hardwood.

The mop water controls were viewed as useful enough for choosing water output, but evidence was limited to basic water-level use.

Dock and auto-empty reliability was a significant concern in customer reviews, especially base failures within months.
