Our verdict
The dual swappable batteries and washable 5-layer HEPA filter make this an appealing option for households that want extended cleaning sessions without stopping to recharge, and the Kompressor bin-squashing trick meaningfully delays how often you empty it. It won't suit anyone looking for a self-emptying dock or a wet-and-dry/mop-combo machine, since neither is part of the package. With only a EU price point around €799 and no confirmed UK figure, shoppers should check local pricing carefully before assuming value.

Suction power, battery and runtime
LG rates the CordZero A9 Kompressor's Smart Inverter Motor at 200W of suction power (AW) on its maximum setting. LG has not published a breakdown of suction output across the individual power modes for this specific SKU, so only the peak figure is confirmed.
The source data lists a runtime range of 12 to 120 minutes, which most likely reflects maximum power (shortest runtime) versus the lowest suction setting (longest runtime) rather than a single continuous figure - this should be confirmed against LG's official mode-by-mode runtime chart before relying on it. Because two batteries are included, swapping the spare in mid-clean extends total usable time beyond a single charge. A full charge takes around 4 hours.
Bin capacity and filtration
The dust bin holds 0.44 litres before compaction. LG's Kompressor system presses collected dust and debris down, and the manufacturer states this effectively extends capacity to roughly 1.06 litres before the bin needs emptying, reducing how often you handle it. Filtration runs through a 5-layer HEPA system, and the filter is washable rather than a disposable part, which can lower running costs over time. This combination makes the model relevant for households managing allergies or pet hair, both listed as intended use cases in the manufacturer data.
Weight, size and what's in the box
At 2.7kg, this sits in the standard weight band for cordless stick vacuums (LG's own dimensions list it at 270 x 260 x 1120mm). The box includes two rechargeable batteries, a charging dock, a universal multi-surface brush, a pet hair brush, a combination tool, a cleaning brush, a flat nozzle and a pre-filter. Other listed features include an adjustable telescopic tube, thumb-touch control, LG ThinQ app connectivity and Smart Diagnosis for troubleshooting via the app. It is not self-emptying, and it is not a wet-and-dry or mop-combo machine - it is dry vacuuming only, across carpet and hard floors.
Price and where to buy
LG's own German product page does not display a price directly, so check current UK retailer listings for today's price. As with any price on this site, confirm the current figure with a retailer before buying. Voltage and per-mode noise level were also not confirmed for this SKU and are not stated here as a result.
Who this vacuum suits - and who should look elsewhere
Based on the verified specs, this model fits households wanting a lightweight, app-connected cordless stick vacuum with washable HEPA filtration and a dual-battery setup for longer cleaning sessions, particularly where pet hair or allergies are a concern. It is less suited to anyone specifically wanting a self-emptying dock, a wet-and-dry or mop-combo function, or a confirmed UK price before committing. If any of those matter more, it's worth comparing other cordless stick vacuums side by side on the same specs first.
How long does the LG CordZero A9 Kompressor A9K-CORE1S run on a charge?
The verified data lists a runtime range of 12 to 120 minutes, likely representing maximum power versus the lowest suction setting. A full charge takes around 4 hours. The exact mode-by-mode breakdown should be confirmed with LG before purchase. Because two batteries are included in the box, swapping the spare in mid-clean extends total usable time well beyond that single-charge range, which is useful given the compact 0.44L bin needs emptying more often than larger cordless models. At 2.7kg, the unit stays light enough to hold comfortably across a full 120-minute low-power session, and the 5-layer HEPA filter keeps working throughout without needing attention during that time.
Does the LG CordZero A9 Kompressor have HEPA filtration?
Yes, it uses a 5-layer HEPA filtration system, and the filter is washable rather than disposable. That combination is aimed at households managing allergies or pet hair, both listed as intended use cases for this model. The washable design should help keep running costs down over time compared with vacuums needing replacement filters, and it works alongside the Kompressor bin-compaction system, which presses debris down inside the 0.44L bin to extend its effective capacity to roughly 1.06L before emptying. Combined with the 2.7kg weight and dual battery setup, this positions the A9 Kompressor as a lightweight, allergy-conscious option among LG's cordless stick vacuums.
How much does the LG CordZero A9 Kompressor A9K-CORE1S weigh?
It weighs 2.7kg, which falls in the standard weight range for cordless stick vacuums. That's manageable across the model's runtime range of 12 to 120 minutes depending on power mode, and it houses a 5-layer washable HEPA filter and a 0.44L bin that compacts to roughly 1.06L via the Kompressor system. Dimensions are listed at 270 x 260 x 1120mm, consistent with a typical upright stick vacuum shape. Given the dual swappable battery design, that 2.7kg figure describes the vacuum body with one battery fitted for use, rather than the combined weight of both batteries and the charging dock included in the box.
Is the LG CordZero A9 Kompressor self-emptying?
No, it has a 0.44L bin that compacts up to roughly 1.06L using LG's Kompressor system, but it must be emptied manually - it does not have a self-emptying dock. That means more frequent manual emptying than a self-emptying model would require, though the compaction system extends how long you can go between empties compared with a same-sized bin without it. The included charging dock handles battery charging only, taking around 4 hours per battery, not bin emptying. At 2.7kg, emptying the compact bin by hand isn't a heavy task, and the washable 5-layer HEPA filter inside means dust exposure during emptying should be limited compared with a disposable filter design.
What is included with the LG CordZero A9 Kompressor A9K-CORE1S?
The box includes two rechargeable batteries, a charging dock, a universal multi-surface brush, a pet hair brush, a combination tool, a cleaning brush, a flat nozzle and a pre-filter. That's a fairly complete accessory set, and the two batteries in particular extend total runtime well beyond the 12-to-120-minute single-charge range by letting you swap in a fresh pack mid-clean. The pet hair brush and universal multi-surface brush cover both carpet and hard floors, working alongside the 5-layer washable HEPA filtration and 0.44L compacting bin. LG ThinQ app connectivity and Smart Diagnosis troubleshooting are also included as features, though no self-emptying dock is part of the package.
How much does the LG CordZero A9 Kompressor A9K-CORE1S cost in the UK?
Prices vary by retailer and over time, so check current UK retailer listings for today's price. As with any price on this site, confirm the current figure with the retailer before buying. For that price, you get a 2.7kg cordless stick with a dual-battery setup, a 5-layer washable HEPA filter, and LG's Kompressor bin-compaction system extending the 0.44L bin to roughly 1.06L effective capacity. Because this figure is aggregated from EU sources rather than a single confirmed UK GBP listing, and no self-emptying dock or wet-and-dry function is included at this price, it's worth comparing against other cordless stick vacuums with a directly confirmed UK price before committing.
