LG CordZero A9 review

The A9 Ultimate is the top-of-the-range model in LG's CordZero stick vacuum range. In addition to the usual array of vacuum heads, it comes with a rotating mop that automatically dispenses water during operation.

With an RRP of $1,349, LG is positioning the A9 Ultimate as a direct competitor to the Dyson V11. However, I'm not entirely convinced that it's worth such a hefty price tag, given the inherent limitations of stick models (this is a criticism that applies equally to Dyson).

But if you're willing to pony up the cash, the A9 Ultimate is an excellent vacuum that ticks all the important cleaning boxes, including battery life, ease of use and versatility.



  • Easy to use and assemble
  • Minimalist user interface
  • Seven heads and nozzles included
LG CordZero A9

The LG CordZero A9 Ultimate follows the same design template as other stick vacuums on the market. The concept is similar to a dustbuster, just bigger and a lot more powerful. It features a battery-operated motor and charging stand, a compact dust bin and a series of detachable vacuum heads connected to a telescopic vacuum pipe.

Unlike cheaper stick vacuums, the LG CordZero A9 Ultimate comes with a pair of interchangeable Lithium-Ion batteries. You can charge these independently of the vacuum using the supplied stand.

LG hasn't skimped on the attachments either. You get four motorised nozzles (including the aforementioned rotating mop), a flexible crevice tool, a mattress nozzle and a short bristle brush for collecting hard dirt. In all, there are seven head attachments included in the package.

All of the attachments can be mounted to the charging stand, which results in a conspicuously tall and bulky unit. It is possible to "downsize" the floor stand if space is limited, but you will then need to store the nozzles somewhere separately. The package also includes a wall mount if you prefer a permanent fixture.

The control layout comprises three thumb buttons: power on/off and a pair of -/+ buttons that toggle between Normal, Power and Turbo Modes. Sadly, there's no inbuilt screen apart from a primitive battery gauge. At this price, we were expecting an LED display similar to the Dyson V11 and Roborock H6. As it stands, it's not always clear which power mode you're using, especially if you're hearing-impaired.

In terms of appearance, the LG CordZero A9 Ultimate is reminiscent of Dyson's Stick Vacuum range, featuring a similar gun-shaped body in muted silvers and greys. The telescopic pipe and nozzles share a similar colour scheme, which I personally prefer to Dyson's vibrant reds.

The package comes with two removable filters that can be washed and reused.



  • Works on most surfaces
  • Dust bin latch is troublesome
LG CordZero A9

LG is pitching the CordZero A9 Ultimate as a complete replacement for your corded canister vacuum and trusty mop. The included attachments are designed to tackle almost any household surface.

There are dedicated, motorised heads for carpets, hard floors, mopping and bedding, plus three non-powered nozzles that rely on the vacuum's suctioning power. Short of pot-plant topiary, there's not a whole lot the A9 Ultimate can't do (on paper, at least.)

According to LG, the A9 Ultimate's motor creates artificial whirlwinds of air to help separate and suck up dust particles while cleaning. This is assisted by the rotating rollers in the motorised heads. It all sounds very impressive, but can a battery-powered vacuum really compete with a traditional AC-powered unit?

I tested the LG CordZero A9 Ultimate on carpet, lino, a shag rug, a hardwood floor and some crumb-strewn bedsheets, using the intended nozzle for each task.

It performed well in each test, with the exception of the rug. Even at the highest setting, debris remained stubbornly embedded in the pile. If your carpets are thicker and shaggier than average, this could be problematic. But for most users, the A9 Ultimate is powerful enough to get the job done – just.

Special mention must also go to the Multi-Surface Power Drive Mop which is the real star of the package. This is a motorised head attachment that allows you to vacuum and mop at the same time. It achieves this via a pair of rotating cloth cleaning pads and a plastic tank that automatically dispenses water to keep the fabric damp. You can choose to have the water spray out at either six or eight-second intervals. Four mop pads are included in the box.

With the standard Power Drive Nozzle attached, the LG CordZero A9 Ultimate weighs around 3kg. This is pretty standard for a high-end stick vacuum (the Dyson V11 Absolute weights 3.05kg, for example).

While smaller children might struggle with the size and weight, it's less cumbersome than a traditional corded vacuum and a lot more fun to use. Kids will be chomping at the bit to earn their pocket money with this thing.

The adjustable vacuum pipe extends to a maximum of 1.12 metres. This should eliminate the need to stoop uncomfortably, no matter how tall you are.

While we wouldn't call it quiet, the LG CordZero A9 Ultimate certainly isn't the noisiest vacuum on the market. LG rates it at 86db in Turbo mode, which sounds about right. In Normal mode it passes the "TV test" – I vacuumed around my lounge room without receiving any angry comments from family members watching Netflix.

The A9 Ultimate has a bin capacity of 0.44 litres, which is around half the size of the Dyson V11 Absolute. Nevertheless, it remains large enough to do a full house clean without any issues (provided your house isn't ridiculously filthy). LG has tried to make emptying the dust bin easy via a release button, but we found the mechanism a bit fiddly.

As mentioned, the charging stand has a large footprint and stands around half a metre tall. While it's not as bulky as a traditional barrel vacuum, you can't really toss it into a cupboard out of sight due to the charging requirements. It looks handsome enough, but just be mindful that it's going to be on display somewhere in your household.

Battery life

Battery life

  • Includes dual batteries
  • Up to 40 minutes per battery (but only technically)
Roborock H6

The LG CordZero A9 Ultimate package includes two interchangeable 2,000mAh batteries. This effectively doubles your battery life and allows you to charge one battery while using the other.

It also makes battery replacement easier, which should help to prolong the life of the product (by contrast, a model like the Roborock H6 requires you to replace the entire vacuum if the battery goes kaput). Battery replacements aren't cheap though, with LG charging around $140 for a new battery.

LG rates each battery at "up to 40 minutes". However, this is a little misleading, as it refers to a non-motorised nozzle running at the lowest possible suction setting. In reality, you're going to be using the motorised head in Turbo Mode for most carpets.

This results in a far less impressive battery life of around 10 minutes. With that said, the inclusion of an extra battery means you can easily swap batteries mid-clean. This gives you a minimum of 20 minutes cleaning time between charges.

You can charge one battery while using the other, although this isn't as handy as it sounds. A full charge takes somewhere in the region of 3.5 hours, which makes multiple charge-and-swap relays impossible.

Should you buy the LG CordZero A9 Ultimate Handstick Vacuum?

  • Buy it if you want a versatile stick vacuum and mop for multiple surface types
  • Don't buy it if you need something cheap and simple

The LG CordZero A9 Ultimate Handstick Vacuum is a good all-rounder that is capable of cleaning and mopping most household surfaces. The inclusion of removable batteries is also highly appreciated. However, at over a grand in price, it's prohibitively expensive even when compared to a Dyson and not as powerful as a traditional high-end vacuum.

If money is no object and you like the idea of a motorised mop, the LG CordZero A9 Ultimate is an excellent choice. For everyone else, try one of LG's cheaper CordZero models instead.
