Compare LG CordZero A937 Cordless Stick Vacuum vs Dyson Gen5 Detect Cordless 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.

The Gen5 Detect is repeatedly praised for a premium, practical tool bundle, typically including the Fluffy Optic head for hard floors, the Digital Motorbar head for multi-surface use, the Hair Screw tool for upholstery, plus additional combo tools and a wall dock for storage and charging (exact bundles can vary by retailer/variant).

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.

Design impressions are consistently premium, with Dyson’s signature tech-forward look and solid feel, though many reviewers also describe the body as bulkier than lighter cordless competitors.

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.

Smart behavior is repeatedly tied to built-in sensors: Auto mode can detect dirt levels and sometimes floor changes to adjust suction in real time, improving cleaning confidence and helping runtime by using high power only when needed (without relying on an app ecosystem).

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

A recurring performance quirk is blowback or scattering of lighter debris (like sugar or small litter) during certain pickup scenarios, where the vacuum’s strong airflow can move debris around until you slow down, reposition, adjust head gates/vents, or make extra passes.

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

Across reviews, setup is described as fast and straightforward (often taking only a minute or a few minutes), with clearly fitting parts and flexible charging options via direct plug-in or the included wall dock for charging and storage.

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 performance is a major strength, with many sources citing up to ~70 minutes in Eco/low power and strong runtimes even in Auto depending on head and floor type; the pack is described as removable/swappable and charging is typically via wall dock or direct plug-in, with recharge times commonly cited around roughly 3 to 4.5 hours.

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 Gen5 Detect uses a bagless bin that reviewers commonly describe as about 0.2 gallons (around 0.75–0.77L / ~750 mL), which is typical for premium stick vacs but smaller than uprights and notably smaller than the Gen5 Outsize variant.

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 is generally described as robust and premium, but a recurring caution is minor flex around the built-in crevice-tool/wand area and occasional durability concerns about specific floorhead parts (like a wheel) even if the main body feels solid.

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 performance is generally above average and can lift impressive amounts of embedded fine grit, but several test-driven reviews note the head can get pulled down into plush carpet (reducing clearance for larger debris) and may require slower passes, vent/gate adjustments, or occasional brushroll intervention on thick rugs.

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

Low-pile carpet pickup is consistently reported as excellent (often mid-to-high 90% removal in objective tests), with the main caveat being that very light debris can be pushed or blown aside in certain situations until you make an extra pass or adjust head airflow/gates.

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

Medium-pile carpet deep-clean performance is repeatedly reported as exceptional in test-driven reviews, including perfect or near-perfect embedded-sand results, though several reviewers note it can feel hard to push until gates/vents are adjusted.

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.

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.

In comparative reviews and award roundups, the Gen5 Detect is repeatedly positioned near the top (including winning performance and battery categories in some test ecosystems), while value-focused comparisons often point shoppers toward cheaper alternatives like the Dyson V15 or strong non-Dyson competitors if cost and weight matter more than having the newest flagship.

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.

Controls and feedback are a highlight: an on/off button replaces Dyson’s older trigger, and the LCD provides battery countdowns, mode info, and real-time particulate/dirty-floor feedback; multiple sources also mention on-screen maintenance prompts as part of the experience.

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.

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

The Gen5 Detect is repeatedly positioned as a high-end cordless experience with strong runtime and a dock-based charging/storage setup, but the convenience comes with the trade-off of a heavier, more top-heavy feel than many rivals.

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 frequently cited as best-in-class in test-driven coverage, with perfect or near-perfect crevice performance reported and strong ability to pull debris from tight gaps and channels.

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

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

Dyson’s Fluffy Optic-style laser head on the Gen5 Detect is repeatedly described as extremely bright and effective at revealing otherwise invisible dust (often even in well-lit rooms), encouraging more thorough cleaning and sometimes making users realize their floors were dirtier than expected.

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.

Ease-of-use feedback is strongly positive around the on/off button (no trigger fatigue), Auto mode, the laser head, and the built-in crevice/dusting tool for quick transitions, but many users still report fatigue from the heavy, top-heavy feel and carpet push resistance during longer sessions.

No summary yet.

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.

Emptying uses Dyson’s point-and-shoot style lever that ejects debris and includes a wiping action, which many find quick and relatively hygienic, but multiple reviewers note it can still be dustier than sealed auto-empty stations and may be messier for allergy sufferers if emptied indoors.

Multiple reviews note that the LCD interface includes maintenance messaging, such as notifying the user when the filter needs attention (washing/replacement guidance varies by source and phrasing).

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.

Reviewers and test outlets consistently frame the Gen5 Detect as a sealed HEPA cordless vacuum with excellent dust containment, frequently citing top-tier filtration results and Dyson’s claims of capturing extremely fine particles, making it a strong option for allergy-conscious homes.

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.

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 repeatedly described as excellent (including near-total pet-hair removal in some tests), though a few reviews note occasional leftover clumps on thicker carpet that are typically resolved with an extra slower pass.

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

On hard floors, reviewers commonly describe reliable hair pickup with the floorheads, aided by the detangling design so hair is more likely to be directed into the bin than wrapped around the roller during typical cleaning.

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

The Digital Motorbar’s detangling features earn strong marks for reducing hair wrap in testing, but some Dyson-focused coverage notes that very long hair can still collect around axle/gap areas, so occasional brush/roller checks may be needed depending on household hair length.

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.

On hard floors, the Gen5 Detect is repeatedly described as exceptionally effective on fine dust, with the Fluffy Optic laser exposing particles that are easy to miss and multiple tests reporting near-perfect pickup that leaves floors noticeably cleaner.

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 on hard floors is generally strong, but several reviews note scatter or plowing with certain items (like kernels, rice, or pieces that get pushed aside), meaning slower forward passes or placing the head directly over debris can be needed for a fully clean sweep.

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.

Maintenance is generally straightforward thanks to washable filtration and cleanable rollers, plus tool/bin disassembly for periodic cleaning; several reviewers note the display can prompt filter care, and some call out that washing the filter requires ample drying time before reinstalling.

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.

Handling reviews are mixed: the vacuum can maneuver well on hard floors and reach under furniture, and the heads include features (like adjustable gates/vents) that reduce carpet drag, but the strong suction can make it harder to push on many carpets and some users notice plowing or resistance depending on direction and debris type.

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 in a typical high-performance cordless range, with measured results commonly landing around high-60s dB on Eco, mid-70s dB on Auto/Medium, and high-70s to low/mid-80s dB on Boost/Max, though some Dyson-focused testing notes the Gen5 can get especially loud at higher settings.

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

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

Across all reviews, the Gen5 Detect is framed as a top-performing, tech-packed cordless vacuum with standout battery life/efficiency, strong filtration, and the laser head’s visibility benefits, but its heavy/top-heavy ergonomics, occasional edge/large-debris quirks, and very high price mean it best fits buyers who prioritize peak Dyson tech over value or lightweight comfort.

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

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.

For pet households, reviewers repeatedly highlight strong suction paired with the detangling Digital Motorbar head and the Hair Screw tool, which together reduce clogs and make it easier to lift fur from carpets, stairs, upholstery, and pet beds.

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.

Price and value are the most consistent drawbacks: many sources characterize the Gen5 Detect as a near-$1,000 flagship that can be hard to justify versus cheaper models with similar practical cleaning, though sales, refurbished purchases, and buyers who prioritize the newest Dyson tech often view it as worth the splurge.

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.

Real-world low-power runtime is consistently positioned as a class leader, commonly cited around ~70–75 minutes on Eco depending on head and floor type, with Auto runtimes often in the mid range; multiple comparative tests also credit it as a battery-life award winner versus other cordless models.

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.

Stair cleaning is regularly described as strong thanks to the motorized tools (especially the Hair Screw / mini motor tool), with the main limitation being the unit’s top-heavy feel during longer handheld sessions rather than a lack of cleaning ability.

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.

Several reviews note it is top-heavy and generally not designed to stand upright on its own, so most owners will rely on the included wall dock for stable storage and charging rather than parking it freestanding mid-clean.

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 lab-style testing and reviewer comparisons, the Gen5 Detect is consistently described as an airflow and suction standout (often cited around 262 AW), delivering elite deep-cleaning power that can translate into outstanding pickup but also higher push resistance on carpet.

Reviewers often frame the Gen5 Detect as a great fit for small-to-medium homes where its power and runtime feel abundant, but note its bulk and wrist-heavy handheld feel can be less ideal for very tight tasks like detailed car interiors or narrow gaps.

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

No summary yet.

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.

Multiple reviewers call the wand’s integrated crevice/dusting tool a major workflow upgrade: you press a button (or buttons) and immediately switch into detail cleaning without hunting for a separate attachment, then slide it back when finished.

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

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

With the Hair Screw / mini motorized tool and strong suction, above-floor cleaning (sofas, pet beds, car seats, shelves) is often described as very effective, but many reviewers caution that handheld use can feel awkward or tiring because so much weight sits in the handle/wrist.

With two primary floorheads, a fast handheld transition, and specialty tools (notably for hair and upholstery), reviewers broadly describe the Gen5 Detect as highly versatile across hard floors, multiple carpet types, stairs, and above-floor cleaning, with comfort limited most by weight in handheld use.

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.

Multiple sources highlight that the Gen5 Detect is heavier and more top-heavy than many cordless rivals (often cited around 7.7 lb overall and roughly a 5 lb handle), which can be felt most in handheld mode and on carpets where suction creates more resistance.
