Side-by-Side Comparison
| Spec | LG CordZero All-in-One A937KGMS | Shark PowerDetect Cordless Stick Vacuum (IP1251) |
|---|---|---|
| Price | $775.99 | $349.99 |
| Release Year | 2023 | 2024 |
| Machine Type | Dry cordless stick vacuum with a bagless auto-empty charging tower | Dry cordless stick vacuum, converts to handheld |
| Suction (as published) | 210 air watts maximum, per the Home Depot spec sheet. LG's own product page states no suction figure at all | Sources conflict, and none is a suction figure: SharkNinja publishes no air watts and no Pa, describing it only as 'Shark's most powerful cordless suction' under ASTM F558 in Boost. Abt's spec sheet lists 380 W at 21.6 V, which is input power drawn, not suction delivered |
| Runtime, Eco / Headline (min) | 120✓ | 70 |
| Runtime, Max Power (min) | Not published by the manufacturer | Not published by the manufacturer — Shark quotes only 'up to 70 minutes' |
| What the Runtime Claim Actually Means | LG states the condition itself: 'up to 120 minutes' is two 60-minute batteries added together, in Normal mode, without a power nozzle attached. Fit the Dual Floor Max nozzle and the figure drops sharply; LG publishes no per-mode table | SharkNinja states the 70 minutes is ECO mode at the handheld unit — no wand, no powered floor head. Shark publishes no figure at all for Boost with the DuoClean Detect nozzle fitted |
| Removable Battery | Yes — two quick-release batteries included, and the tower charges both simultaneously | Yes — removable 21.6 V pack, but only one is included |
| Spare Battery | Not published by the manufacturer | Not published by the manufacturer; Shark does not list a price on the product page. Third-party XBATR-series replacements are widely sold |
| Dock / Wall Mount | All-in-One Tower included: free-standing, charges both batteries, stores tools and auto-empties the bin | Charging stand and charging cord included. The PowerDetect auto-empty base is a separate product (IP3251) and cannot be added to this one later |
| Filtration | 5-step filtration with a HEPA element, LG claims 99.99% of dust; the tower adds a 3-stage filter claimed at 99.9%. LG publishes no whole-machine seal certification | Sources conflict: SharkNinja lists felt and washable-foam pre-motor filters plus a HEPA post-motor filter, while Abt's spec sheet for the same SKU says 'no HEPA filter'. Shark does not claim its Anti-Allergen Complete Seal on this cordless model, though it does on the corded PowerDetect |
| Bin / Tank Capacity | Kompressor compresses the contents — LG claims 2.4x the capacity of a non-Kompressor bin. The tower is bagless | 0.7 qt (23.68 oz) dust cup with a bottom-release flap — debris drops out but your hand stays above the opening |
| Weight (lbs) | 5.95✓ | 7.96 |
| Filters, Consumables & Self-Clean | Cyclone and filters are removable and washable, so there is no scheduled filter purchase. The bagless tower means no consumable bags either | Foam and felt pre-motor filters are washable and Shark specifies a monthly rinse. Replacement brushrolls and filters are stocked by SharkNinja |
| Warranty | 12 months | 60 months |
| Colors | Iron Grey | Dark Gray, Navy, Purple/Gray, Teal |
Category Scores
Suction Power
The Shark PowerDetect Cordless Stick Vacuum (IP1251) leads clearly here, 8.5 against 7.5 — a 1.0-point margin on actual cleaning force at the head, judged on air watts where a maker publishes them and discounted where only Pa or motor watts are quoted. If that is what you are buying for, the LG CordZero All-in-One A937KGMS does not close the gap elsewhere.
Sustained Runtime
The LG CordZero All-in-One A937KGMS leads clearly here, 8.0 against 5.5 — a 2.5-point margin on how long the machine really runs on max power with the motorised floor head attached — not the eco-mode, bare-tool figure on the box. If that is what you are buying for, the Shark PowerDetect Cordless Stick Vacuum (IP1251) does not close the gap elsewhere.
Filtration & Sealing
The LG CordZero All-in-One A937KGMS leads clearly here, 8.0 against 6.5 — a 1.5-point margin on whether the whole machine is sealed or a HEPA element simply sits inside a leaky body, and what the claimed rating is actually measured at. If that is what you are buying for, the Shark PowerDetect Cordless Stick Vacuum (IP1251) does not close the gap elsewhere.
Handling & Ergonomics
The LG CordZero All-in-One A937KGMS leads clearly here, 9.0 against 8.0 — a 1.0-point margin on weight, balance, whether power is a push-button or a trigger you must hold, and how it stores. If that is what you are buying for, the Shark PowerDetect Cordless Stick Vacuum (IP1251) does not close the gap elsewhere.
Maintenance & Emptying
The LG CordZero All-in-One A937KGMS leads clearly here, 9.0 against 7.5 — a 1.5-point margin on bin or tank emptying, whether your hand ends up near the dust, self-clean quality and the ongoing cost of filters, bags and detergent. If that is what you are buying for, the Shark PowerDetect Cordless Stick Vacuum (IP1251) does not close the gap elsewhere.
Battery System
The LG CordZero All-in-One A937KGMS leads clearly here, 9.5 against 6.5 — a 3.0-point margin on removable or sealed, how many packs are included, what a spare costs and whether the pack is shared across a range. If that is what you are buying for, the Shark PowerDetect Cordless Stick Vacuum (IP1251) does not close the gap elsewhere.
Versatility
The LG CordZero All-in-One A937KGMS and Shark PowerDetect Cordless Stick Vacuum (IP1251) are level here, at 7.5/10 each. handheld conversion, above-floor tools, carpet capability and wet-mopping ability is not what separates these two — look to the categories where the scores diverge.
Value
The Shark PowerDetect Cordless Stick Vacuum (IP1251) leads clearly here, 8.5 against 7.5 — a 1.0-point margin on what you actually get for the street price once consumables and missing accessories are counted. If that is what you are buying for, the LG CordZero All-in-One A937KGMS does not close the gap elsewhere.

Pros & Cons
LG CordZero All-in-One A937KGMS
Pros
- +The only machine here that ships with two batteries, and the tower charges both at once — a genuine 2x working session
- +The auto-empty tower is bagless, so unlike Samsung's Clean Station there is nothing to keep buying
- +5.95 lb is the lightest full-size stick vacuum on this page
- +Kompressor physically compacts the bin contents, so you empty it far less often than a 0.5 L rival
Cons
- −The 120-minute headline is two batteries combined, in Normal mode, with no power nozzle fitted — LG's own footnote says so
- −210 air watts sits well under Dyson's 240 and Samsung's 400, and LG only publishes it on retailer spec sheets, not its own page
- −Only 1 year of parts-and-labour cover; the 10-year figure covers the motor alone
- −LG's US stick line churns fast — the A927 and A929 siblings are already discontinued
Shark PowerDetect Cordless Stick Vacuum (IP1251)
Pros
- +The MultiFLEX wand folds so it stands on its own and lies flat under a sofa — Dyson has no equivalent at any price
- +Push-button power rather than a held trigger, which is the ergonomic complaint people actually leave Dyson over
- +5-year limited warranty on the unit is by far the longest here
- +Detection genuinely modulates suction by floor type and dirt level rather than just lighting up an icon
Cons
- −The 70-minute claim is ECO at the bare handheld with no wand or floor head — the honest working figure is much lower and Shark publishes none
- −Shark publishes neither air watts nor Pa, so this machine cannot be compared on paper against anything else in the category
- −Sources disagree on whether this SKU even has a HEPA filter, and Shark pointedly does not claim a sealed anti-allergen system on it
- −One battery in the box and no published spare-battery price
