The LG CordZero A9 Kompressor Cordless Stick Vacuum Cleaner with Dual Battery, 200W Suction Power - Fantasy Silver (A9K-CORE1S) doesn't have one fixed UK price. Like most cordless stick vacuums, what you pay depends on which retailer is selling it, when you look, and whether it's part of a bundle or promotion at that moment. Rather than guess a figure, this page sets out what tends to move the price of this specific model and where UK shoppers typically go to check it.
Is there a current price for the LG CordZero A9 Kompressor?
We don't currently have tracked retailer offers for the A9K-CORE1S in our dataset, so we're not going to quote a number here — any figure we didn't verify against an actual listing wouldn't be reliable, and prices on cordless vacuums shift often enough that a static figure goes stale quickly anyway. If you want to see live pricing once retailers are tracked for this model, our comparison tool is the place to check rather than relying on a number printed on this page.
What affects the price of this model
A handful of specific features on this machine tend to push cordless stick vacuum pricing up relative to simpler single-battery models:
- Dual battery pack. The A9K-CORE1S ships with two rechargeable Li-ion batteries plus a charging dock, rather than one. Two batteries cost more to produce than one, and together they support up to 120 minutes of total runtime rather than the shorter window a single-battery machine would give.
- Kompressor dust compaction. This is the feature that gives the model its name. It mechanically compresses debris inside the 0.44L bin so it can hold roughly as much dirt as a 1.06L bin before it needs emptying. Compaction hardware adds cost compared with a plain bagless bin of the same size, but it also means fewer trips to the bin during a cleaning session.
- Smart Inverter Motor rated for 200W max suction, plus an adjustable telescopic tube for reaching different floor and furniture heights.
- Washable HEPA filtration, which avoids the ongoing cost of replacement filter cartridges, though washable filters still wear out and need replacing eventually.
- Connected features — LG ThinQ app connectivity, Smart Diagnosis, and thumb-touch control — which are more common on higher-tier models than on basic corded or single-battery cordless vacuums.
- Accessory bundle. The set includes a universal multi-surface brush, pet hair brush, combination tool, cleaning brush, flat nozzle, and pre-filter, alongside the two batteries and dock. A richer bundle generally sits at a higher price point than a bare unit with one or two tools.
Weight (2.7kg) doesn't directly set the price, but lighter cordless machines with this level of motor and battery specification tend to sit toward the upper end of the category rather than the entry level.
Kompressor vs Tower: why the two LG A9 models are priced differently
LG sells more than one A9-series CordZero model, and it's worth being clear about which one this page covers. The A9K-CORE1S reviewed here is a standalone dual-battery stick vacuum: it stores and charges on a regular dock, and you still empty the bin by hand — the Kompressor compaction just means you do it less often. LG also sells an A9T-ULTRA1C Tower variant, which adds an All-in-One Tower dock that automatically empties the bin after every use, plus dual PowerPack batteries and a mop attachment for hard floors. That auto-empty dock and mopping capability are the reason the Tower variant typically commands a higher price than the Kompressor model on this page. If automatic bin-emptying and mopping matter more to you than keeping the price down, the A9T-ULTRA1C Tower is the model to look at instead of this one. If a simpler dual-battery machine with less frequent manual emptying suits you better, the Kompressor is the one to compare against other cordless stick vacuums in the same price bracket.
Where UK shoppers typically check the price
For a model like this, UK buyers typically compare pricing across three types of source: major electricals retailers, LG's own UK online store, and general online marketplaces. Each can list different stock levels, bundle contents, or short-term promotions at any given time, which is exactly why a single quoted price tends to go out of date fast. Checking more than one source before buying is a reasonable habit for any vacuum in this price bracket, since the same model can be bundled with different accessory sets or warranty terms depending on where it's sold. For the fullest breakdown of how this model performs beyond price — suction, runtime, noise, and handling — the full LG CordZero A9 Kompressor Cordless Stick Vacuum Cleaner with Dual Battery, 200W Suction Power - Fantasy Silver (A9K-CORE1S) review covers that in more depth than pricing alone can.
Key specs to confirm before you buy
When comparing this model's price against alternatives, make sure you're comparing the same specification. The A9K-CORE1S's core numbers are:
| Spec | Detail |
|---|---|
| Max suction power | 200W |
| Runtime | Up to 120 minutes (with two batteries) |
| Bin capacity | 0.44L, expands to 1.06L with Kompressor compaction |
| Filtration | HEPA, washable |
| Weight | 2.7kg |
| Battery | Li-ion, 2 included |
| Dock type | Standard charging dock (not auto-empty) |
| Colour | Fantasy Silver |
If a listing you're comparing has a noticeably lower price, check whether it includes both batteries, the full accessory set listed above, and the standard warranty — a cheaper listing sometimes reflects a reduced bundle rather than a genuine discount on the same configuration.
What is the maximum suction power of the LG CordZero A9 Kompressor A9K-CORE1S?
200W, delivered by LG's Smart Inverter Motor. That sits it in the mid-tier for cordless stick vacuums rather than at the top of the suction spectrum, and it's paired with an adjustable telescopic tube for reaching different floor and furniture heights. Suction power alone doesn't determine cleaning performance here — the Kompressor dust compaction feature means the 0.44L bin holds roughly as much dirt as a 1.06L bin before it needs emptying, so you empty it less often even without a higher-suction motor. At 2.7kg, the machine stays light enough for one-handed use despite carrying two Li-ion batteries.
Does the A9K-CORE1S come with an auto-empty dock?
No. It uses a standard charging dock rather than an auto-empty base. Kompressor dust compaction reduces how often the bin needs emptying — compressing debris so the 0.44L bin holds roughly as much as a 1.06L bin would uncompressed — but emptying is still done by hand rather than automatically. LG's separate A9T-ULTRA1C Tower model is the one with an All-in-One Tower dock that empties the bin automatically after every use, plus dual PowerPack batteries and a mop attachment, which is why the Tower typically costs more than this Kompressor model.
How many batteries does this model come with?
Two rechargeable Li-ion batteries, supporting up to 120 minutes of combined runtime, plus the charging dock they sit in when not in use. Two batteries cost more to produce than the single battery found on simpler cordless stick vacuums, which is one of the features that pushes this model's price above entry-level single-battery machines. The dual-battery setup is separate from the Kompressor dust compaction feature, which reduces how often you need to empty the 0.44L bin but doesn't affect runtime. At 2.7kg, the machine remains light enough to carry both batteries without feeling front-heavy during use.
Is the filter washable?
Yes, it uses washable HEPA filtration, which avoids the ongoing cost of replacement filter cartridges, though washable filters still wear out eventually and need replacing. This is one of several features — alongside the dual Li-ion battery pack, Kompressor dust compaction, and LG ThinQ app connectivity — that push the A9K-CORE1S toward the upper end of the cordless stick vacuum price range rather than the entry level. The Smart Inverter Motor delivers up to 200W max suction alongside this filtration, and the whole unit weighs 2.7kg.
What colour option does the A9K-CORE1S come in?
Fantasy Silver is the only colour option listed for the A9K-CORE1S. It's the standard finish for this dual-battery configuration, distinct from LG's separate A9T-ULTRA1C Tower model, which pairs its auto-empty dock and mop attachment with its own finish. Since there's no tracked retailer price for this model, colour isn't a factor that changes the cost here the way it sometimes does on other cordless vacuums where different finishes carry different price points — the A9K-CORE1S's price is instead driven by its dual Li-ion batteries, Kompressor dust compaction, Smart Inverter Motor, and washable HEPA filtration rather than by finish or colourway.
