Compare LG CordZero A937 Cordless Stick Vacuum vs Dyson Gen5 Outsize Cordless Vacuum Cleaner

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 tool set is widely praised: two main floorheads plus a hair screw tool, combination/dusting tools, and a built-in crevice tool cover most home scenarios. Some reviewers note that many attachments can become a storage hassle if you do not have a dedicated dock or stand setup.

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.

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.

Auto/Medium mode and sensor-driven suction adjustments are frequently mentioned as helpful, reducing the need to manually switch settings. The automation is generally appreciated even when the particle-count visuals are seen as less useful day to day.

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

Some reviews note airflow can cause minor blowback with very small debris in certain situations. It is presented as an occasional annoyance rather than a major failure, but it’s a notable edge case for a high-suction cordless vacuum.

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

Setup is straightforward for the vacuum itself, but docking options can add complexity. Wall-mount docks may require drilling, while freestanding stand options (when included) are viewed as easier and more renter-friendly.

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 setup is a standout: the Outsize commonly includes two swappable batteries and an extra charger, enabling long sessions and easy battery swaps. Charge times are described as typical for the category, but the ability to rotate batteries is a major usability win.

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 larger 0.5-gallon (about 1.9 L) bin is a core Outsize advantage and reduces how often you need to empty during large cleans. The tradeoff is added bulk, and a few reviewers note that runtime may end before the bin fills for some households.

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 described as premium and well-finished, consistent with Dyson’s reputation. Minor notes include small flex around the built-in crevice tool area, but overall durability impressions are strong.

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 pickup is also reported as strong, with lab-style results in the high‑90% range and good hair handling. A few comparisons suggest the Outsize’s wider head can slightly reduce concentrated deep-clean performance versus the Gen5 Detect, but still scores well above average.

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

On low-pile carpet, test results and reviewer feedback indicate strong pickup and good deep-cleaning ability for a cordless stick vacuum. Performance is generally framed as premium-tier, though some comparisons suggest the standard-width Gen5 Detect can be slightly more effective per pass.

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

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.

Clogging and tangle-related interruptions are reported as rare in testing, especially with pet hair and long hair. A few reviewers note potential hair wrapping around side axles/gaps, but overall debris flow and anti-tangle systems reduce maintenance compared with many cordless rivals.

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.

Comparisons often favor the Gen5 Detect for lighter weight and slightly better concentrated performance, while the Outsize is preferred for capacity and coverage speed. Against older Dysons, reviewers highlight incremental improvements (runtime, filtration, features), but some argue the performance leap over a V15 may be smaller than the price gap.

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 readouts are generally considered excellent: an on/off button (no trigger hold), mode switching, and an LCD that shows time remaining and alerts. The particle-count display is often viewed as novelty, but real-time runtime and troubleshooting info are valued.

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 handheld easily and includes effective handheld tools, but several reviewers warn the Outsize can feel wrist-heavy for longer above-floor tasks. Some recommend using a hose accessory to make handheld and dusting jobs more comfortable.

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

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 cleaning is generally strong, helped by the included crevice tool and high suction. Some review testing reports only minor issues in crevice-specific trials, suggesting it performs reliably for gaps and grooves on hard floors.

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.

The Fluffy Optic green laser is one of the most-cited features and is widely considered genuinely useful for hard floors. Reviewers say it makes fine dust visible and encourages more thorough cleaning, though it can be a bit unsettling for anyone sensitive to seeing every speck.

Handling is strong for floor cleaning, especially in open areas where the wider head covers more space per pass. The flip side is added bulk and weight, making tight spaces and prolonged handheld use less comfortable than on lighter Dyson models.

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.

Usability is rated highly overall thanks to an on/off button, strong pickup, helpful tools, and clear runtime readouts. The biggest usability negatives are the heavier feel and bulk, plus occasional comments that the lack of a trigger can lead to leaving it running between rooms and wasting battery.

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 is described as quick and low-mess, and the larger bin reduces how often you need to do it. Transparent bin design also helps users see what’s collected and avoid surprises before dumping.

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.

Filtration is repeatedly described as top-tier, with a fully sealed system and HEPA media that targets very small particles. This is framed as a meaningful upgrade for dust containment compared with less-sealed cordless competitors.

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.

Floorhead design is widely praised: the Fluffy Optic head excels on hard floors and the Motorbar XL adds faster coverage for larger spaces. Some testing suggests the wider XL head can slightly reduce suction concentration versus a standard-width head, but overall pickup remains excellent.

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

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

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

Hair-wrap resistance is repeatedly praised, with testing showing near-zero tangling on the brushroll and effective detangling combs. A minority of comments mention hair can wrap on side axles/gaps, but overall maintenance burden from hair is low.

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.

Hard-floor fine dust pickup is consistently described as exceptional, especially with the Fluffy Optic head that both reveals and removes fine particles. Multiple reviewers comment that floors look cleaner than expected once the laser highlights what’s left behind.

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

Hard-floor large-debris pickup is excellent in both testing and real-world anecdotes, including piles of debris, pet hair, and even hay-like material. Reviewers highlight strong intake and consistent results across different hard-floor mess types.

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

Multiple sources describe the Gen5 series as state-of-the-art cordless vacuum tech, highlighting the laser illumination, sensors, improved filtration, and strong power specs. Innovation is framed more as a premium refinement than a necessity for every buyer.

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

Routine maintenance is generally described as simple (emptying the bin, maintaining filters), and anti-tangle systems reduce brush cleanup. The main practical maintenance complaint is organizational: lots of tools need a good storage solution to avoid losing attachments.

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 described as typical for high-power cordless vacuums: not quiet, but manageable. Measured figures and reviewer impressions generally place it around the high‑60s to high‑70s dB depending on mode, with Boost being noticeably louder.

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

Onboard tool storage is a clear convenience win: the built-in crevice/dusting tool stored in the wand is frequently praised for quick cleanup without hunting for attachments. This design is cited as improving everyday usability over older Dyson models.

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

Overall sentiment is very positive on cleaning performance and feature set, with several reviewers placing it among the best cordless vacuums available. The strongest reservations are about price and the heavier, bulkier feel compared with non-Outsize alternatives.

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.

Pet hair performance is a highlight: multiple tests report excellent fur pickup and very low clogging, even with heavy shedding. The included hair-focused tools (hair screw and detangling floorhead) are repeatedly called out as effective for pet owners.

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 is the most consistent complaint. Reviewers often describe the Gen5 Outsize as best-in-class but hard to justify unless you specifically want the XL bin, wide head, and included extra battery; otherwise, the Gen5 Detect or older Dyson models are frequently cited as better values.

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.

Eco/Low runtimes are commonly reported around 70–75 minutes per battery depending on head, which is excellent for a high-power cordless. With the included second battery on Outsize packages, reviewers emphasize that total cleaning time can exceed two hours for large homes. Boost/Turbo runtime is much shorter, often reported in the ~7–15 minute range per battery depending on the test and head. Several reviews suggest Boost is best reserved for occasional deep-clean bursts rather than whole-home cleaning.

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.

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 feedback is mixed: wall docks can require drilling and can feel finicky for renters, while a freestanding stand (where available) is praised for keeping tools organized. Overall, the Outsize footprint and accessory count make storage planning more important than with smaller stick vacs.

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.

Reviews consistently describe suction and real-world pickup as elite for a cordless stick vacuum, with lab-style results around 98% debris removal. A few comparisons note the wider XL head can spread suction over more area, slightly reducing concentration versus the standard-width Gen5 Detect, but performance remains well above average.

The Gen5 Outsize is repeatedly framed as ideal for big cleans: large homes, heavy debris loads, and pet owners. The combination of high pickup, big bin, and two-battery runtime supports longer sessions without frequent stops.

The Outsize format is less ideal for cramped areas. Several reviewers note difficulty in very tight spots (for example, car seats or compact nooks) and recommend considering a smaller model if you mainly clean small rooms or do lots of spot-cleaning.

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

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.

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.

Above-floor cleaning is effective thanks to strong suction and the hair screw tool, but the Outsize’s weight makes extended handheld or overhead work more fatiguing. Reviewers suggest it’s best as a primary floor vacuum rather than a lightweight dusting tool.

Versatility is a consistent strength: the combo of a hard-floor roller and an all-floor Motorbar head is repeatedly praised for mixed flooring. Reviewers commonly describe it as effective across hardwood/tile and carpets without frequent tool swaps.

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.

Weight is one of the biggest drawbacks. Multiple reviews cite around 8.6 lb (about 3.9 kg) and describe it as noticeably heavy for wrist-intensive handheld work, stairs, and overhead cleaning compared with lighter stick vacuums.
