LG may be best known for TVs and appliances, but their CordZero handstick vacuum line has quietly become one of the most innovative options in the cordless vacuum market. With features like dual batteries, auto-empty stations, and Kompressor technology, LG brings unique engineering to the cordless vacuum space. Here’s how the CordZero lineup breaks down, on LG’s own published figures, so you can decide whether LG deserves a spot in your cleaning cupboard.
LG CordZero Lineup Overview
Models on LG’s US Site (2026)
| Model | What LG highlights | Runtime (LG rating) | Status |
|---|---|---|---|
| All in One (A939KBGS) | Auto-empty tower, Power Mop, 2 batteries | Up to 120 min (both batteries) | Discontinued |
| All in One (A937KGMS) | Auto-empty tower, Dual Floor Max nozzle, 2 batteries | Up to 120 min (both batteries) | Listed |
| All in One (A949KTMS) | Auto-empty tower, Power Mop Pro and Dual Floor Max nozzles | Not in LG’s listing summary | Listed |
| Kompressor (A925KSM) | Kompressor bin, Dual Floor Max nozzle, 2 batteries | Up to 120 min (both batteries) | Listed |
| Kompressor with ThinQ (A923KGMP) | Kompressor bin, ThinQ, Dual Floor Max nozzle | Up to 60 min | Listed |
| Kompressor with ThinQ (A941KTMP) | Dual Floor Max nozzle, ThinQ | Up to 100 min | Listed |
| CordZero (A913BM) | Single quick-release battery, telescopic wand | Up to 50 min | Listed |
Runtimes are LG’s ratings from its US listings, measured in Normal mode; the powered nozzles and higher modes cut them.
Understanding LG’s Model Codes
LG sells these under long descriptive names plus a model code, and retailers often shorten them to “A9” or “A9 Kompressor”. The code is the only reliable identifier, so match it against LG’s page before buying rather than trusting a retailer’s short name.
Kompressor Technology Explained
LG’s signature innovation is the Kompressor lever, a mechanical system that compresses collected debris in the dustbin.
How It Works
- Collection: Debris enters the dustbin through cyclonic separation
- Compression: The Kompressor lever pushes debris down
- Compaction: Dust and hair are pressed into the bottom of the bin
- Result: LG rates it at up to 2.4 times the capacity of an uncompressed bin
Practical Benefits
- Less Emptying: Compress hair and dust instead of making frequent trips to the trash
- Tidier Emptying: Compacted debris is less likely to puff out when you empty the bin
- Hygiene: Less contact with collected dirt
We couldn’t find a published test of how many rooms a compressed bin lasts, so treat the 2.4x figure as LG’s own capacity rating rather than a promise about emptying frequency.
Performance Analysis
Suction Power
LG CordZero models use Smart Inverter Motors producing:
All in One (A939KBGS):
- Three power modes: Normal, Power and Turbo
- 370 W power consumption on a 25.2 V battery system
- No suction figure on LG’s page
Kompressor with ThinQ (A941KTMP):
- LG calls it the best suction across a range of floor types among its US cordless sticks
- No air-watt figure in LG’s listing
Suction Power in Context
Air watts measure cleaning power at the nozzle, not just motor wattage, which is why the 370 W consumption figure on the All in One’s spec sheet can’t be compared with a Dyson air-watt rating. LG says its multi-cyclone system maintains suction as the dustbin fills.
Battery Technology
Dual Battery System (All in One):
- Two quick-release lithium-ion batteries included
- Up to 120 minutes on the pair, by LG’s rating, in Normal mode without the powered floor nozzles
- Swap the second battery in when the first runs down
- 3.5-hour charging time
LG doesn’t publish per-mode runtimes for the All in One, so expect far less than 120 minutes in Power or Turbo, or with the powered nozzle fitted. Across the range, LG says most CordZero models recharge in about 4 to 5 hours.
Filtration System
LG lists a 5-step filtration system among CordZero features, with a washable cyclone and filters on models such as the A913BM and A916BM. LG doesn’t describe it as HEPA on the A939KBGS page, so we don’t either. Rinse the washable parts on the schedule in your model’s manual and let them dry fully before refitting.
Noise Levels Across Modes
LG lists 84 dB for the A939KBGS but doesn’t say which mode that is, and we couldn’t find per-mode figures for the line. Expect noise to rise from Normal through Power to Turbo, as it does on every cordless stick.
Design and Usability
Weight and Maneuverability

LG says most of its stick vacuums weigh 6 to 7 pounds without accessories; the A939KBGS is 5.95 lbs by LG’s figure. That puts them in the same band as most mainstream cordless sticks, and the handheld unit comes off for stairs and upholstery.
Ergonomic Considerations
LG lists one-touch control on models such as the A916BM, and an adjustable-length wand, so you can switch on and change modes without shifting your grip much.
Attachments and Tools
What’s in the box varies by model. LG’s A939KBGS page lists the Universal Power Nozzle, Power Mini Nozzle and Power Mop Nozzle, plus a combination tool and crevice tool. Current models swap in the Dual Floor Max nozzle, which LG describes as a carpet agitator and hard-floor soft roller in one head. Check the in-the-box list on LG’s page for the exact model code.
Stand and Storage
Portable Charging Stand:
- Freestanding, so there’s no wall mounting
- LG lists it with models such as the A916BM and A926KSM
All-in-One Tower (A939KBGS and other All in One models):
- Empties the dustbin automatically
- Stands on the floor and stores the vacuum
- Hidden tool storage
- A portable charging stand is also included for the batteries

Comparison to Competitors
vs. Dyson V15 Detect
| Feature | LG All in One (A939KBGS) | Dyson V15 |
|---|---|---|
| Status and tier | Discontinued | Premium |
| Suction | Not published | 240AW |
| Runtime | Up to 120 min (two batteries, Normal) | 60 min |
| Weight | 5.95 lbs | 6.8 lbs |
| Dust tank | 33.8 oz (LG figure) | 0.77L |
| Stand | Auto-empty tower | Wall mount only |
| Laser dust detection | No | Yes |
Verdict: Dyson publishes a suction figure and LG doesn’t, so raw power can’t be settled on paper; LG wins on rated runtime, weight and the auto-empty tower, but only the Dyson is still sold new. For a full assessment, see our Dyson V15 Detect review.
vs. Samsung Jet Series
LG and Samsung compete directly in the cordless stick market, and both bring consumer electronics know-how to the category. Samsung has its own bin-compression approach. LG’s case is the dual-battery models and the freestanding stand; we haven’t compared suction because LG publishes no air-watt figure for its sticks.
Real-World Performance Scenarios
Scenario 1: Whole-Home Cleaning (2,500 sq ft)
With the All in One’s two batteries, LG’s up-to-120-minute rating in Normal mode covers a long session, though the powered nozzles and higher modes cut into it. Start with the first battery in Normal mode for general floor cleaning throughout main living areas. When it runs down, swap in the second. Use Power mode for high-traffic carpeted areas and Turbo for spot-cleaning stubborn debris. The ability to clean continuously without waiting for charging makes the dual battery system particularly valuable for larger homes or thorough cleaning sessions.
Scenario 2: Daily Quick Clean (Apartment/Small Home)
For daily maintenance in smaller spaces, a single battery provides more than adequate runtime. The Normal mode setting efficiently handles everyday dust, crumbs, and light debris across hard floors and area rugs. A freestanding charging stand positioned in a central location means the vacuum is always ready for quick pickups. Kompressor models suit this well, as you can compress debris from multiple quick-clean sessions before needing to empty the bin, reducing total time spent on vacuum maintenance.

Scenario 3: Pet Hair Intensive Cleaning
Pet owners are who the Kompressor models are aimed at. The Dual Floor Max nozzle on current models agitates carpet to lift embedded hair, and the handheld unit handles furniture and pet beds. After collecting hair, the Kompressor lever presses it down into a compact mass, and that’s the point of it: less of the web-like tangle that clings to the walls of a standard dustbin.
Who Should Buy an LG CordZero?
Perfect For:
- Multi-story homes: Portable charging stand moves with you
- Pet owners: Kompressor handles hair efficiently
- Allergy sufferers: 5-step filtration and auto-empty towers that cut contact with dust
- Convenience seekers: Stand requires no installation
- Extended cleaning: Dual batteries eliminate downtime
Not Ideal For:
- Tight budgets: More expensive than basic cordless
- Small apartments: Features may be overkill
- Spec-sheet shoppers: LG publishes no suction figure, so there’s nothing to set against Dyson’s air-watt ratings
- Minimalists: Stand takes floor space
Long-Term Ownership Considerations
Expected Lifespan and Durability
LG publishes no lifespan figure for the CordZero line. What it does publish is the warranty: on the All in One, 10 years on the Smart Inverter Motor against 1 year for parts and labor. Batteries are the part that wears, and LG doesn’t publish a cycle-life figure, so budget for a replacement at some point. For general battery troubleshooting advice, our guide on why cordless vacuums lose charge covers the fundamentals. The plastic construction isn’t indestructible, and a clear plastic dustbin is the part most exposed if it’s dropped on a hard surface.
Cost of Ownership
Beyond the initial purchase price, consider these ongoing costs:
Annual Costs:
- Filter replacement: low cost
- Brush roll replacement (if needed): low cost
- Cleaning solution for washable parts: minimal
Occasional Costs:
- Battery replacement (every 2-3 years): moderate investment
- Additional attachments: low to moderate each
- Kompressor seal replacement (rare): minimal
Compared to traditional upright vacuums, cordless models have higher battery replacement costs but eliminate bag expenses and typically have lower motor repair costs.
Maintenance Tips
Weekly:
- Empty dustbin after each use
- Check brush roll for hair wrap
- Wipe exterior with damp cloth
Monthly:
- Wash pre-filter and cyclone
- Check attachments for blockages
- Inspect battery contacts
Annually:
- Replace filters if worn
- Check for worn parts
- Deep clean all components
Troubleshooting Common Issues
Reduced Suction:
- Check for blockages in wand and nozzle
- Clean or replace filters
- Empty and clean dustbin
- Inspect brush roll for tangles
Battery Not Charging:
- Verify power connection to charging stand
- Clean battery contacts with dry cloth
- Try alternate battery if available
- Check for error codes on LED display
Brush Roll Not Spinning:
- Remove and clean brush roll
- Check for hair or debris jamming mechanism
- Inspect drive belt for wear
- Verify proper attachment connection

Final Verdict
LG CordZero handstick vacuums represent a compelling alternative to more mainstream brands like Dyson and Shark. While they may not offer the absolute highest suction power on the market, they excel in practical features that matter for daily use: extended runtime through dual batteries, innovative Kompressor technology that reduces maintenance frequency, and a freestanding charging system that requires no wall installation.
Value is strong across the lineup, particularly at the mid-range price points. In particular, the Kompressor models such as the A925KSM pair two batteries with the compressing bin, while the discontinued All in One showed how far LG took the idea, with two batteries, an auto-empty tower and a mop nozzle in one box. Auto-empty and extended battery models serve niche needs but represent solid engineering for buyers who want those specific features.
For homes with pets, allergies, or simply a preference for less frequent dustbin emptying, LG’s Kompressor technology alone puts these vacuums on the shortlist. Combined with LG’s battery expertise, thoughtful design, and competitive pricing, the CordZero lineup deserves its place among the top cordless vacuum options available in 2026.

Frequently Asked Questions
- How does LG Kompressor compare to Samsung's compression feature?
- LG's Kompressor is a manual lever, so you decide when to compress, and LG rates it at up to 2.4x the capacity of an uncompressed bin. We couldn't find published data that compares its reliability or compaction with Samsung's system.
- Can I buy extra batteries for my LG CordZero?
- The batteries are quick-release, so a spare swaps in without tools, and the dual-battery models ship with two. Check LG's parts store against your model code before buying a spare, because we couldn't find LG confirming that every CordZero battery fits every model. Third-party batteries aren't covered by LG's warranty terms for its own parts.
- Does the auto-empty station justify the extra cost?
- The auto-empty station suits allergy sufferers or those who dislike touching vacuum contents. However, it adds meaningfully to the price, so it's a luxury feature. The tower's bag still needs emptying now and then, and the tower takes up floor space.
- How does LG's warranty compare to Dyson and Shark?
- On the CordZero All in One (A939KBGS), LG's page lists 1 year on parts and labor and 10 years on the Smart Inverter Motor, against Dyson's 2-year and Shark's 5-year warranties.
- Are LG CordZero vacuums good for pet hair?
- LG builds them with pet hair in mind. The motorised floor nozzles (the Dual Floor Max on current models, with a carpet agitator) go after embedded hair, and the Kompressor models press hair into the bottom of the bin so it's easier to empty.
- Can the CordZero handle fine debris like flour or drywall dust?
- Like most cordless vacuums, the CordZero isn't designed for heavy construction dust. LG fits a 5-step filtration system, but very fine dust like flour can clog filters more quickly than normal household dirt. If you regularly clean fine dust, plan to clean or replace filters more frequently than the standard maintenance schedule suggests.
- Do LG CordZero models work well on thick carpet or high-pile rugs?
- The motorised floor nozzles are built for household carpet and rugs. Very thick or high-pile carpet is harder going for any cordless stick. Turbo mode adds power for it, though LG's long runtime ratings are for Normal mode, so expect much less in Turbo.
