LG's CordZero A9 family is built around two ideas: two swappable batteries in the box for long runtime, and a Kompressor lever that squashes dirt in the bin so you empty it less often. The A9T versions add an All-in-One Tower that empties, charges and stores the stick. It is a capable, well-thought-out cordless, but UK availability is patchier than Dyson, Shark or Samsung, so price and stock should drive the decision.

Key specs

Figures are taken from LG's published specs, which vary slightly by market and version. Encouragingly, LG publishes runtime with the powered floor nozzle as well as the best-case figure, which gives a realistic picture. The older original A9 has shorter runtimes than the Kompressor models, so check which generation you are buying.

Design and handling

The CordZero is a conventional stick with a pistol-grip handheld at the top. At around 2.6kg it is reasonably manageable, lighter than many rivals with a dock. LG's main design trick is the Kompressor: a lever on the bin that pushes the dirt down, compacting it so the bin holds more before you empty it. It also helps scrape hair and dust off the bin's mesh.

The handheld is also usable with an extension, and the telescopic wand on many versions adjusts to your height, which taller owners appreciate. Storage depends on the version: a wall mount or a floor-standing stand for the A9K, the All-in-One Tower for the A9T.

Cleaning performance by floor type

Carpets

The Power Drive nozzle is effective on short and medium-pile carpets, and independent reviews broadly rate pick-up as good, though not quite at the level of the strongest Dyson models on deep pile. Power mode helps on thick carpets, at the cost of runtime.

Hard floors

Good, particularly with the soft-roller head included in some bundles. Some A9T versions add a Power Drive Mop nozzle with spinning pads for light mopping, useful in kitchens but not a substitute for a dedicated wet-and-dry cleaner; see best wet and dry cordless.

Pet hair

Short pet hair is handled well. The Kompressor lever helps stop hair from clogging the bin, and the tower's self-emptying keeps contact with hair to a minimum.

Stairs and above-floor

The handheld is compact enough for stairs and the car. Two batteries mean you can do floors and stairs on the same day without waiting to recharge.

Battery and charging

This is the CordZero's standout feature. Two batteries come in most bundles, so with the floor nozzle in Normal mode you can expect around 40 minutes each, around 80 minutes in total. That is enough for a large home in one session. Charging takes around four hours per battery, so charge both in rotation.

Bin, filtration and maintenance

The 0.44-litre bin is small on paper, but the Kompressor lever means it holds more than the number suggests. On the A9T, the All-in-One Tower empties the bin automatically into a bag, keeping dust exposure low. As with any self-emptying system, bags are an ongoing cost and the emptying cycle is briefly loud.

LG uses a multi-stage filtration system with washable filters. Clean them regularly. Our HEPA filters guide explains filtration claims.

Versions and UK availability

LG uses suffixes on model codes (for example, MAX, PRO or ULTRA variants) that differ by retailer and market. UK stock has been less consistent than for the big three brands, so check LG UK and major retailers, and make sure UK spares and warranty support apply before buying from a marketplace seller. Our LG cordless hoover guide covers the range.

Who should buy the CordZero A9?

The CordZero makes sense for larger homes that need long runtime without paying extra for a second battery, and for people who want fewer bin trips thanks to the Kompressor lever. The A9T with its tower suits allergy sufferers and pet owners who want hygienic emptying. Taller users also benefit from the telescopic wand.

It is harder to recommend if you cannot buy it from a mainstream UK retailer at a competitive price, or if you need a machine with easy, long-term parts support. Dyson, Shark and Samsung are simpler to buy and service in the UK, and their prices drop more predictably in sales.

Reliability and parts

LG's cordless hoovers have a reasonable reputation for build quality, and the swappable batteries mean wear is shared between two packs, which can extend their useful life. The main risk is parts availability in the UK in future years, given LG's lower profile in floorcare here. Check that batteries, filters and tower bags are in stock before you buy, and keep your receipt for warranty claims. Our warranty guide explains your rights under the Consumer Rights Act.

Pros and cons

Alternatives worth considering

• Samsung with a tower: the Samsung Bespoke Jet, more widely available in the UK.
• Dyson flagship: the Dyson V15 Detect for maximum carpet pick-up.
• Self-emptying for less: see our best self-emptying cordless hoover guide.
