Compare LG CordZero A937 Cordless Stick Vacuum vs Shark PowerDetect Corded Stick 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.

Included tools (crevice, upholstery, pet) cover basic needs and many reviewers like the flexibility for stairs and furniture. Common asks are a dedicated dusting/soft brush attachment and, for some, a better-performing pet power brush.

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.

Aesthetics get light praise: several mention the sleek look and distinctive purple/eggplant finish. This is generally secondary to performance in the reviews.

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.

PowerDetect/Detect mode is praised for automatically adjusting behavior when moving between hard floors and carpet, usually switching quickly. A few users say it can misread uneven surfaces or flip modes during repositioning, so the manual floor modes are useful.

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

Area rug handling is mixed: many people use it successfully on typical area rugs, but lightweight throw rugs are commonly reported to get sucked into the head. That can trigger a red light/shutoff and may require switching modes, lifting technique or using attachments.

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

Assembly is repeatedly described as fast and straightforward, typically involving snapping a few parts together. Multiple reviewers say they were cleaning within minutes of opening the box.

Obstruction/overheat protection shows up as indicator lights and can stop the vacuum when something jams or when a rug gets pulled in. This is useful for safety, but can be triggered by very thin rugs and requires a reset.

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.

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 dust cup is widely considered small for whole-house cleaning, especially with pets, so expect frequent emptying. The upside is that it is clear and easy to remove and reinsert.

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 impressions are mixed: many call it sturdy for an under-10-pound stick vacuum, while others emphasize that it is mostly plastic and worry about hinges, connectors or the cord over time.

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.

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

On low-pile carpets and rugs, most reviews report strong pickup and good transitions from hard floors. A few mention occasional drag or the need to select a specific mode for best feel.

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

Medium-pile carpet cleaning is frequently described as deep and thorough, with visible grooming lines and a surprising amount of hidden dirt pulled out. Some users say the head can feel strong enough to tug forward or require extra effort depending on the rug.

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 prevention is typically strong, with many users reporting sustained suction and minimal brush roll clogging. Issues tend to appear when the small bin is overfilled, which can dirty filters faster or trap hair in the cyclone area.

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.

Comparative comments skew very positive, with multiple owners saying it outcleans older Shark Rockets and even some Dysons, Kirbys or canisters by pulling out more hidden dirt. A few still prefer bigger uprights for capacity and all-day cleaning.

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 are generally described as simple and intuitive, with an easy toggle between Detect, hard floor and carpet modes plus a visible floor-type display. A few people would prefer additional options such as a reduced-suction setting for delicate rugs.

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.

The convertible handheld design is frequently used for stairs and above-floor tasks by detaching the wand or main unit. Owners like being able to switch quickly without needing a separate handheld vacuum.

Multiple reviewers call out a long cord (commonly cited around 30 feet) that can cover several rooms before re-plugging. Some customers still wish for a swivel or retractable design despite the reach.

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

Cord management is the most consistent complaint: the cord is frequently described as thick, stiff and prone to kinking or tangling, which can affect maneuverability and even feel like a tripping hazard. A smaller set of owners say it is manageable with careful wrapping or breaks in over time.

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.

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

Cyclone separation is generally viewed as effective at keeping dirt in the bin and supporting consistent suction. A few hands-on testers note string or hair can snag in the cyclone pathway, especially if the bin is overfilled.

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

Handling is generally described as nimble thanks to a lighter body, swivel steering and a head that can get into corners and around furniture. The main negatives are top-heavy feel for some users and the stiff cord, which can fight your turns.

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 is widely rated high: one-button start, clear mode switching and simple emptying encourage more frequent cleanups. Pain points are usually about cord stiffness, small bin stops and occasional mode confusion on uneven floors.

Edge and baseboard cleaning receives both praise and criticism. Many credit the DuoClean-style head for pulling debris right up to edges, while some report reduced suction at the very front of the head near walls and prefer using the crevice tool for corners.

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 generally described as quick and low-mess: the bin pops off and dumps easily, encouraging more frequent cleanouts. Some mention occasional hair/debris clinging inside the bin area.

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.

Sealed HEPA-style filtration is a standout in both expert writeups and owner feedback, with several people noting less dust escaping while vacuuming. Washable pre-filters and a large HEPA filter are appreciated for ongoing ownership.

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 dual-roller floorhead design earns high marks for multi-surface pickup and for cleaning on both the forward and backward stroke. A few users report quirks, such as the front soft roller reducing suction right at baseboards or the head feeling stiff on certain carpets.

A few reviewers highlight the rubber squeegee/seal as helping maintain contact and suction on hard floors for better debris pickup, including on the backward stroke. Most feedback focuses more on overall hard-floor pickup than the seal itself, with edge-near-wall suction being the bigger point of debate.

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 consistently rated excellent, with owners reporting noticeably more pet and human hair removed compared with prior vacuums and fewer repeat passes. Very delicate throw rugs can be an exception because the suction can grab the rug itself.

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, reviews frequently mention strong pet-hair pickup without scattering, including around litter areas. Performance is generally described as reliable across tile, wood and vinyl.

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 a major strength: multiple testers report little-to-no hair wrapping on the brush rolls, even with heavy pet shedding. Still, some note hair can collect in corners of the soft roller or in the cyclone/bin area and needs occasional cleaning.

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.

For fine dust on hard floors, the soft roller and sealed filtration help capture dusty residue that other vacuums can miss, according to several owners. One critical review notes it may not pull dust from deep gaps in older, uneven wood floors without using attachments.

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 a clear highlight: multiple reviewers call out rice, salt, cat food and kitty litter being captured quickly with minimal bounce or scatter. Forward-and-backward pickup can reduce the need for repeated passes.

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

Headlights are commonly praised for making dust and debris easier to see. Some reviewers also note the lights act as status/warning indicators, and a few wish illumination stayed available when using the unit in handheld configurations.

Low-profile design helps it fit under some furniture and reach under cabinets more easily than bulkier uprights. Clearance is not universal, and at least one owner reports it still could not fit under a particular couch.

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

Maintenance is moderate: filters are washable and brush rolls resist tangles, but owners with pets often clean filters more frequently to maintain suction. Some also mention periodic cleaning of sensors/rollers and replacing the odor cartridge if used.

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 feedback trends positive, with many calling it quieter or less obnoxious than older vacuums. It is still loud enough to be noticeable, and a few mention unexpected loudness or squealing on back strokes on rugs.

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

The odor neutralizer is polarizing: many like the light fresh scent and adjustable intensity, while others find it unpleasant and remove or discard the cartridge. When used, it can help with pet-related odors such as litter.

Onboard tool storage is convenient for some (keeping a crevice or upholstery tool at hand), but others find the storage clip awkward or that tools get in the way. The larger pet tool may not store neatly on the unit.

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

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-focused performance is a core strength: reviews highlight strong fur pickup, anti-tangle rollers, HEPA sealing and an optional odor feature that can help around litter. The main pet-related downside is more frequent bin emptying and mixed opinions on the pet brush tool.

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.

Value is often rated high because performance is compared favorably to pricier brands while staying in a midrange price band. Detractors argue the stiff cord and small dust cup keep it from feeling premium.

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.

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.

Several reviews describe a glide or self-propelled feel in forward motion, making routine vacuuming easier. Others report inconsistent push effort on certain carpets, ranging from effortless to a bit draggy.

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.

For stairs, the lighter weight and the ability to reconfigure into a compact handheld/wand setup are repeatedly called out as helpful. Several users say it is far easier than hauling a traditional upright.

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.

Self-standing storage is frequently mentioned as a big quality-of-life upgrade, letting users pause without leaning the vacuum on furniture. A few people still use a hook/wall-style storage approach depending on how they store it.

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 repeatedly describe very strong suction for a corded stick, often pulling embedded grit and pet hair from carpets and quickly grabbing messy debris like kitty litter or rice on hard floors. A minority note it can feel almost too strong on light rugs or be a bit draggy on some carpets.

The compact, lightweight form is repeatedly recommended for small apartments and tight storage, especially compared with canisters and uprights. The long cord also reduces outlet switching in smaller layouts.

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

Reliability sentiment is cautiously positive: several shoppers cite strong ratings and a multi-year warranty, but long-term durability is still uncertain for many. Concerns include cord wear and the longevity of plastic hinges or clips.

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.

Most reviewers find swapping tools and converting configurations straightforward with simple release buttons. A small number say the new connections can feel tight at first compared with older Shark models.

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

Under-furniture pickup is often helped by the low-profile head and lightweight feel, with several users cleaning under cabinets, beds and sofas more easily than with uprights. A few note certain couches are still too low or that lighting is limited in handheld mode.

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 a strong use case: owners report good pickup on couches, car seats and stairs once converted to handheld or wand mode. Feedback on the pet tool is mixed, with at least one complaint that the pet power brush feels underpowered.

Versatility is a recurring positive: the vacuum transitions between carpets, hard floors, stairs and above-floor tasks with minimal fuss, and forward/backward pickup is frequently highlighted. Owners who dislike batteries also like that corded power supports longer sessions.

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 under 10 pounds, the vacuum is commonly described as light and easier on backs than full-size uprights. Some users still feel strain because weight sits higher near the handle.
