Compare LG CordZero A937 Cordless Stick Vacuum vs Dyson V12 Detect Slim Vacuum

Reviews highlight a generous accessory set (including mini motorized and mop options) with convenient storage, but some shoppers report confusion about what is included or wish for additional hard-floor heads.

Most packages include two full-size heads plus crevice/combination tools and the Hair Screw Tool; reviewers consistently call the accessory set high quality and genuinely useful.

Many reviewers like the sleek, premium look of the vacuum and tower and feel comfortable leaving it out rather than hiding it in a closet.

Reviews often compliment the premium Dyson look and polished plastics, though some note the finish can scuff, chip, or peel over time.

The LG ThinQ/Wi-Fi features provide status and usage history, but many reviewers consider the app optional and a few report pairing or usefulness frustrations.

At least one reviewer reports debris scatter or blowback on hard floors (especially with light, bulky bits), contributing to frustration with messy pickups.

On some area rugs and runners, the Motorbar can feel too grabby or trip, so users often switch to Eco mode or use the fluffy head for smoother gliding.

Setup is usually straightforward, though some owners say the instructions are unclear and the tower doors or alignment can be finicky.

Setup is mostly snap-together and quick out of the box; installing the wall dock is optional but adds convenience and stability.

Some users report the Motorbar can stop spinning on certain rugs or when it grabs bulky items, requiring a quick reset—protective, but interruptive.

Dual batteries and a tower that charges the spare are major positives, but real-world longevity varies and some owners report batteries that degrade, fail, or do not meet advertised claims.

Battery is removable and typically takes about 4–4.5 hours to charge. Runtime is ample for small homes but can fall short for multi-level deep cleans unless you add a spare.

The onboard bin is small and the Kompressor can compact fluffy debris, while the self-empty tower relies on proprietary bags that add convenience but also cost and occasional mechanical complaints.

The bin is notably small (around 0.1 gal/0.38 L). That keeps weight down but forces frequent emptying—especially in larger homes or heavy pet-hair cleanups.

Build impressions vary: some praise a premium feel, but customer reviews include repeated reports of breakage, tower failures, overheating, or motor problems over months of use.

Build quality feels tight and premium in most reviews, but a few note small annoyances like finish wear or parts that can feel finicky during emptying or disassembly.

High-pile and rug cleaning is generally a strength, with good pickup scores and strong pet-fur results compared with its hard-floor chunky-debris performance.

High-pile carpet and shag are more challenging: performance can be decent but less consistent, and strong suction can cause sticking or slow progress.

Low-pile carpet pickup scores well in testing and is commonly described as reliably strong for everyday carpet cleaning.

Low-pile carpets are handled well for everyday debris, though fine powders can require extra passes or higher power.

Deep-clean tests on carpet show above-average pickup for embedded debris, supporting strong performance on typical medium-pile household carpets.

Medium-pile carpet performance is generally strong for surface debris and pet hair, but deeper extraction is still behind the most powerful cordless Dysons.

Clogging feedback is split: the cyclone design can resist fine-dust prefilter clogging, but many users and tests report jams or blockages with larger debris like cereal or kibble.

The compact bin and airflow path can fill quickly and trigger clog warnings in heavy-duty use, so it works best as a maintenance vacuum rather than a post-renovation workhorse.

Compared with Dyson and Samsung rivals, it competes well on carpet and convenience and can be quieter, but falls behind on hard-floor chunky debris and long-term consistency.

Often positioned as a lighter, slightly less powerful alternative to the V15/Gen5 and a premium step up from older entry Dysons; it also compares well with non-Dyson sticks on usability.

Button-based controls (no trigger) are often described as ergonomic, but some dislike long-press behavior for max power and the overall number of modes and indicators.

The single power button eliminates trigger fatigue and the LCD shows mode, remaining time, particle data, and alerts. A few users still prefer triggers for one-handed on/off control.

The vacuum converts quickly to a handheld for cars, stairs, upholstery, and tight spots, and this flexibility is repeatedly called out as a key benefit.

It converts to a handheld with a button press and is repeatedly described as easier for above-floor cleaning than heavier cordless models.

Cordless convenience is consistently praised thanks to swappable batteries, a dock that charges the spare, and easy grab-and-go daily cleaning.

Cordless design is a major win for quick daily cleanups and room-to-room use, especially in apartments and smaller homes.

Crevice tool results are generally strong, with tests showing good extraction of sand/flour from grooves and owners using it to compensate for chunky-debris issues.

Crevice and groove pickup is above average; several tests show strong usable suction for pulling debris from cracks and grout.

Testing notes the multi-cyclone design helps keep fine debris from loading up the prefilter quickly, supporting steadier suction on dust-heavy jobs.

The slim cyclone design supports strong everyday suction, but some reviews note it is less aggressive than higher-end Dyson cyclone setups, contributing to weaker deep-carpet performance versus flagship models.

Debris illumination is inconsistently reported: one roundup notes LEDs on the mop attachment, while many owners still wish the primary floorhead included lighting.

The green laser illumination on the hard-floor head is widely described as a game-changing feature for spotting fine dust, hair, and debris—especially under furniture and in dim rooms.

The light, balanced feel makes it easy to steer, carry, and use on stairs. Minor handling complaints include Laser head caster quirks and occasional rug resistance.

Day-to-day use is often described as easy thanks to button controls and docked charging/storage, but some friction points include tower doors, app extras, and hard-floor technique.

Most reviews call it user friendly thanks to low weight, button power, and intuitive controls. The main usability downsides are small-bin interruptions and occasional rug-related stoppages.

Edge cleaning is repeatedly called out as a strength, often clearing close to walls without needing a crevice tool, though stubborn powder at edges can take extra passes.

The auto-empty tower is a major convenience and helps avoid dust clouds, but reliability is inconsistent with reports of incomplete emptying, jams, or messy failures.

Point-and-shoot emptying is generally clean and easy, but the small bin can pack tightly and occasionally needs manual clearing of clumps.

The multi-stage system and HEPA bag can contain dust well, yet one lab-style test reports leakage and some owners describe dust plumes or smell during auto-emptying.

Multiple testers describe the system as well sealed with HEPA-level filtration, helping keep fine dust and allergens contained rather than recirculated.

The universal power nozzle works across surfaces but is frequently criticized for pushing chunky debris on hard floors, and several reviewers wish it had a soft roller and/or headlight.

The two-head approach works: Laser Slim Fluffy excels on hard floors while Motorbar handles carpets and hair. Tradeoffs include head-swapping and Motorbar sensitivity on some rugs.

Carpet hair pickup is frequently praised, especially with the mini/pet tools, though occasional tangling and maintenance is still reported with long hair.

Carpet hair pickup is a strong point, with many reports of removing embedded pet fur in a couple of passes.

Hair pickup on hard floors is usually effective, though long strands and fuzz can still contribute to tangles or clogs that require cleanup.

Hair pickup on hard floors varies by head: Motorbar tends to lift hair effectively, while the fluffy head can sometimes push longer strands around depending on floor texture.

Tangle resistance is mixed: short hair often causes little wrap, but long hair can wrap heavily and may require regular brush-roll cleaning.

De-tangling features reduce hair wrap significantly, though some long hair can still collect on roller ends or axles and needs periodic cleanup.

Fine dust on hard floors is mixed: some tests show excellent pickup on sugar/flour, while other owners report pushing debris around depending on head design and technique.

With the Laser Slim Fluffy head, fine dust pickup on hard floors is excellent and highly visual, often revealing and removing particles you would otherwise miss.

Large debris on hard floors is the most consistent weakness; multiple reviews note cereal, Cheerios, and kibble being pushed, left behind, or causing jams.

Large debris pickup is strong overall, though some note the Motorbar can push or miss bigger bits on hard floors compared with using the fluffy head.

Multiple reviewers note the main floorhead lacks a headlight, and some mention LEDs only on certain attachments, creating expectation mismatches.

Washable filters and accessible rollers help, but owners frequently mention hands-on maintenance such as unclogging, cleaning passages, and replacing bags.

Expect frequent bin emptying and periodic filter/roller cleaning. Most find maintenance straightforward, though some testers call it finicky due to the compact bin and occasional clogs.

Handling is generally light and balanced with good swivel action, though the floorhead behavior on hard floors can reduce the feeling of effortless maneuvering for larger debris.

The mop attachment can help with light spot cleaning and shine, but it is not a full mop replacement and some owners report poor results or mechanical issues.

Noise is a standout strength: measured levels are relatively low on standard modes and many users describe it as quieter than competing cordless sticks.

Noise is generally moderate on Eco/Auto and noticeably louder on Boost. Measured dB varies by tester, but most agree it is manageable for a cordless stick vacuum.

A few users mention noticeable odors, particularly during auto-empty cycles, while others do not report smell issues.

The wand clip can carry small tools like the crevice and combination attachments, but onboard storage is limited and does not accommodate the full-size heads.

Ongoing costs can be higher than bagless rivals due to proprietary dust bags and replacement parts, and some mention paying extra for certain accessories.

No bags are needed and filters are washable, but adding an extra click-in battery can raise ownership costs if you need longer runtime.

Longer-term reports describe strong cleaning performance after years of near-daily use, but cosmetic wear (paint chips or rubber coating peel) can show if stored roughly.

Overall sentiment is very positive: owners love the laser-guided hard-floor cleaning and lightweight ergonomics, with the small bin and carpet/rug quirks as the main drawbacks.

Packaging is usually adequate, but there are reports of cracked or damaged tower components arriving out of the box.

Several reviews highlight organized, mostly recyclable packaging with minimal plastic, making unboxing and setup straightforward.

Pet tools and carpet cleaning earn frequent praise for picking up fur, but heavy shedding can contribute to clogs and some owners report the base or chute struggling with pet hair.

Reviewers with pets praise the Motorbar and Hair Screw Tool for pulling fur from rugs, furniture, and pet beds; heavy shedders may still prefer a larger-bin model.

Value is polarizing: some feel the auto-empty convenience justifies the premium, while many owners call it overpriced given hard-floor shortcomings and reliability complaints.

Consistently judged expensive at MSRP, but many consider it a strong buy when discounted because it delivers high-end Dyson features in a lighter chassis.

Measured runtimes vary widely by mode and head, but many users see roughly half an hour to an hour per battery in standard use, with the second battery extending total time. Turbo runtime is short and best treated as a burst mode; several reviews cite single-digit minutes of high power before needing a recharge or battery swap.

Measured Eco/Auto runtimes commonly land around 30–50 minutes with a powered head, varying with floor type and how aggressively Auto boosts suction. Boost mode is best for quick spot cleans; many tests show roughly 7–20 minutes depending on the head used.

Some owners warn that dragging hard grit or pebbles can scratch wood floors if not picked up cleanly, so careful technique matters on delicate surfaces.

The spinning mop system is water-focused with adjustable output and typically discourages detergent use; it is best for light, fresh messes rather than deep cleaning.

Low weight and strong handheld accessories make stairs and vertical surfaces easier than with upright-style vacuums.

The freestanding all-in-one tower is praised for storing tools and charging a spare battery, but multiple reviewers call it bulky and note the doors and clearances can be awkward in tight spaces.

Storage is compact, but it is not reliably freestanding; several reviewers recommend using the wall dock to prevent tipping.

Across tests and owner reports, suction feels strong on carpet and rugs, but overall performance is inconsistent on hard floors and some users report suction drop-offs over time.

Across tests and long-term use, suction feels strong for its size and cleans surface debris extremely well, though it trails larger Dysons for deep carpet extraction.

Repeatedly recommended for studios, apartments, and smaller homes because it is light, compact, and fast for daily touch-ups.

Support experiences are mixed; several owners report frustrating warranty processes, slow turnaround, or being required to ship the full unit for service.

Reviews cite Dyson’s two-year warranty and established service network; reliability is generally viewed as good, with most concerns centered on wear and maintenance rather than failures.

Attachments generally click on and off quickly, and the tower storage keeps tools handy, though some reviewers dislike having to swap tools to handle hard-floor debris well.

Attachments click in with a quick release and most users find swaps easy, but getting best results often means switching between the Laser Slim Fluffy and Motorbar heads.

Several reviews praise the low-profile reach for getting under furniture and the flexibility to clean along edges and into tighter spaces.

The slim head and ability to lay nearly flat make it easy to reach under couches and low furniture, with the laser helping spot dust in dark areas.

Above-floor performance is a strong point: mini motorized tools and crevice attachments are praised for sofas, stairs, vehicles, and tight spots.

The Hair Screw Tool and other attachments are widely praised for pulling hair from couches, beds, stairs, and car interiors, making handheld cleaning a standout strength.

The mop attachment tank is easy to fill and includes adjustable flow settings, though capacity is limited as expected for an add-on tool.

Weight is around the mid-5 lb range; many find it manageable, but whole-home sessions can still feel tiring compared with lighter sticks.

At about 5.2 lb, it is consistently described as one of the lightest premium stick vacs and easier to carry, lift, and use in handheld mode.
