LG CordZero A937KGMS

Verdict

The LG CordZero auto-empty model offers good overall cleaning and exceptional convenience with its quiet operation, dual batteries and auto-empty tower, but it clearly lags behind rivals on large debris pickup. It is best for users who prioritize low noise and hands-off emptying over top-tier hard-floor performance with big particles.

Pros

  • Aesthetic design & finish 3 reviews 5.0
    Reviewers describe the CordZero’s stick and tower as sleek and modern looking, with a premium finish that helps it blend into living spaces rather than looking like a bulky appliance.
  • Convertible handheld design 2 reviews 5.0
  • Maintenance requirements 2 reviews 5.0
  • Build quality & durability 1 review 5.0
    Owners often say the CordZero feels very solid and well built, with materials and fit that convey a high-end, long-lasting machine.
  • Cyclone performance 1 review 5.0
    The CordZero’s multi-cyclonic separation does an excellent job stripping fine dust out of the airstream before it reaches the pre-motor filter, helping the vacuum hold suction and reducing the need for frequent filter cleanings.
  • Hair Pickup — Carpets 1 review 5.0
  • Pet-Ready Features 4 reviews 4.8
    The handheld tools and power mini nozzle work well for pulling pet hair and tracked-in debris from carpets, floors and upholstery, and paired with the chemical-free setup and auto-empty dock this makes the CordZero a reassuring, low-mess option for many pet homes.
  • Cordless convenience 2 reviews 4.8
  • Upholstery / Above-Floor Pickup 2 reviews 4.8
    The powered mini nozzle and larger head both do a strong job pulling pet hair and embedded dirt from sofas and chairs.
  • Noise level 4 reviews 4.7
    Both vacuuming and mopping modes are described as very quiet and almost whisper-like, with the CordZero frequently ranking as the quietest option in side-by-side stick vacuum comparisons.
  • Weight 2 reviews 4.7
  • Maneuverability & Handling 6 reviews 4.7
    The mid size stick design, balanced motor unit, and telescoping wand make the CordZero feel lightweight and easy to maneuver around furniture.
  • Accessories & Tools 7 reviews 4.6
    The CordZero tower kit includes multiple attachments for floors, stairs and upholstery, giving owners flexible options for everyday messes and targeted cleaning jobs.
  • Ease of use 8 reviews 4.5
    Ergonomic controls, simple modes and the all in one tower with auto empty and onboard tool storage generally make the CordZero straightforward for everyday use, though some users find the auto empty cycle slow enough that flipping open the bin over a trash can feels faster for quick cleanups.
  • Emptying & Mess Control 7 reviews 4.5
    The auto empty tower vacuums debris from the small on board bin into a replaceable dust bag whenever you dock it, minimizing dust clouds and dirty hands and keeping emptying largely hands off, though some users feel the auto empty cycle takes long enough that they sometimes prefer to flip the bin open manually for speed.
  • Onboard tool storage 6 reviews 4.5
    The all in one tower hides and stores the main tools and accessories inside the base, keeping everything organized and out of sight, though the side doors only open partway and tend to swing closed, which can make accessing tools a bit fiddly.
  • Area Rug Handling 1 review 4.5
    In testing, the CordZero glides smoothly over flat rugs without stalling or shutting down, making it more reliable on thin area rugs than some rival sticks.
  • Crevice / Groove Pickup (Hard Floors) 1 review 4.5
    Hard-floor crevice testing found that the CordZero quickly pulled most flour out of grooves and cracks, indicating strong performance in gaps and joints.
  • Suction & Airflow 5 reviews 4.4
    Lab measurements show suction and airflow are roughly average for a cordless stick, but the multi-cyclonic design helps it maintain that power so real-world pickup, especially on carpets, is still strong as long as you avoid oversized debris.
  • Battery & Charging 9 reviews 4.4
    Battery life on medium power is strong for its class at around half an hour per pack, and with the extra quick release pack and tower charging many users can swap batteries in seconds and see total runtime stretching close to two hours on lower settings, though max power turbo runs are much shorter.
  • Mopping performance 5 reviews 4.4
    Filters and other routine maintenance parts are easy to access and swap, so upkeep is quick and does not require tools or digging through hidden panels.
  • Carpet — Low-Pile Pickup 4 reviews 4.4
    Reviewers find the CordZero very effective on carpets, usually clearing fine dust and larger debris in a single pass with only occasional extra strokes needed.
  • Versatility 7 reviews 4.4
    With its dual floor nozzle, handheld tools and optional mop attachment, the CordZero is designed to handle mixed flooring and everyday messes, though some tests still find the main head working better on carpets than on hard floors in certain homes.
  • Carpet — Medium-Pile Pickup 2 reviews 4.4
    In deep-clean tests on embedded debris, the CordZero removed roughly three-quarters of the material, an above-average result that trails the best cordless models by only a small margin.
  • Hair‑Wrap / Tangle Resistance 5 reviews 4.3
    Tests show the brush roll resists tangling completely with about 8-inch hair but allows most 14-inch strands to wrap around, so it is excellent for shorter hair yet clearly weaker than top rivals with very long hair.
  • Floor Drying Time 1 review 4.3
  • Filtration / Dust Containment 6 reviews 4.2
    While the multi-stage washable filters are designed to capture fine dust, fog-test results show noticeable leakage from the main body, suggesting weaker overall dust containment than many competing HEPA stick vacuums.
  • Controls & UI 4 reviews 4.1
    The simple three-button layout and tower-top touch panel are easy to understand and, unlike trigger-style sticks, the power button stays on after one press, though having to long-press the plus button to reach max power can still feel slow and fiddly.
  • Overall opinion 9 reviews 4.1
    Overall impressions remain mixed: strong carpet cleaning, long battery life and the convenient all-in-one tower are big strengths, but poor large-debris pickup on hard floors, bulky storage and especially weak dust containment lead some testers to say they cannot recommend it for most homes, particularly those with lots of bare flooring or dust-sensitive occupants.
  • Bin & Bag 8 reviews 4.1
    The dust bin is quite small at around 300 ml and can fill quickly with hard debris, but the compressor mechanism compacts fluffier dirt so the bin holds more between auto-empty cycles into the HEPA dust bag, improving hygiene and reducing trips to the trash.
  • Carpet — High-Pile Pickup 1 review 4.0
  • Stair Cleaning 1 review 4.0
  • Tool-change simplicity 1 review 3.8
  • Runtime (Measured, Default) 2 reviews 3.8
  • AI, Smart & App / Automation 3 reviews 3.7
    The CordZero can connect to Wi Fi and LG’s app so owners can monitor battery level, cleaning history and maintenance reminders from their phone, adding convenience even if the smart features are not essential for every user.
  • Price & Value 5 reviews 3.6
    Because much of the price goes toward the tower, auto empty system and extra battery, the CordZero tends to be best value for shoppers who specifically want that integrated, high convenience setup, but some reviewers feel its high price and weak hard floor performance make it poor value compared with top Dyson sticks.
  • Hard Floor — Fine Dust Pickup 3 reviews 3.5
    Recent lab testing shows the CordZero can clear fine dust from hard floors without much trouble, though earlier reviews saw it sometimes pushing flour or glitter into piles, so results may vary by floor type and mess.
  • Storage footprint & upright-stand stability 3 reviews 3.5
    Owners note that the all in one tower has a relatively streamlined look but is quite large and heavy, taking up more floor space than they would like.
  • Headlight & LED lights 2 reviews 3.5
    LEDs on the cleaning head help highlight dust and spills in front of the vacuum, making it easier to see where additional passes are needed.
  • Solution / Liquid system 2 reviews 3.5

Cons

  • Clogging & debris prevention 3 reviews 3.0
    Multi-cyclonic separation keeps fine dust away from the pre-motor filter so suction stays steady and filter maintenance is infrequent, though oversized lightweight cereal-type debris can still clog the airway and hurt its performance in stress tests.
  • Runtime (Measured, Boost/Turbo) 2 reviews 2.9
  • Hard Floor — Large Debris Intake 5 reviews 1.9
    Tests show the CordZero struggles with larger crumbs and confetti on hard floors, often scattering debris ahead of the brush or across the room rather than pulling it in cleanly.
