When I first heard about LG’s new vacuum cleaner with an “all-in-one tower that cleans up, then cleans itself”, I immediately assumed it was witchcraft.

I live in a good-sized, carpeted and pet-friendly apartment. We have a little ragdoll cat who sheds white fluff everywhere, especially during the summer months. As a result, I have to vacuum every day. That’s why I jumped when I heard about this LG vacuum cleaner that can empty itself.

Before we get started, I need to clarify that “self-emptying” isn’t entirely accurate. To clear up any confusion, when the LG CordZero A9 stick vacuum is placed in its all-in-one tower, all of the dust is sucked out of its body and stored inside a disposable dust bag within the charging station. So you still have to empty the Tower eventually, but it’ll be much easier and hassle-free.

Expensive with additional costs over time, heavy, mop nozzle ineffective, and loud self-emptying system.

First impressions

What does this LG vacuum cleaner come with?

Upon its delivery, what I quickly realised was that the box was immensely heavy. If you decide to go to your nearest electronics store to pick up your model — I cannot stress this enough — make sure you bring a friend or at the very least, get it delivered. The box itself isn’t huge but it is long. I struggled on my own to push the box into my apartment, despite the delivery guy kindly carrying it up the stairs and leaving it at my front door.

When I opened the box, I discovered that the all-in-one tower was the source of all this heavy-lifting. Thankfully, the LG stick vacuum itself is nowhere near as heavy. Inside, you’ll find an assortment of bits and bobs including the stick vacuum (which you need to assemble), four different nozzles, dual battery pack, a mop kit and a number of other accessories to reach those hard to get crevices.

Putting together the LG stick vacuum itself is quite straightforward. In fact, I didn’t even need to look at the instruction manual for guidance. It is separated into four parts: the product body which needs the battery installed, the extension pipe and the nozzle (which is one of four found in the box). Each part clicks into each other but if you would prefer to work with a shorter vacuum cleaner, you don’t have to attach the extension pipe. This is great because it means you can take the LG CordZero A9 into your garage and suck up any dust in your car (like I did).

The charging station

Next up is the auto-empty charging station and thankfully, it doesn’t need any assembly. Ideally, place it somewhere with ample space of about a 20cm radius so that you can open its side doors to store some of its tools and accessories.

The side doors act like a secret compartment and since the design is quite seamless, you wouldn’t even guess it opens up unless you checked the manual. There is an anti-tip kit included in the box, however, I didn’t end up using it despite placing my tower on the carpet. I found that it’s so weighted that it doesn’t need to be secured.

Once you’re all set up, you can gently place the LG CordZero A9 into the charging station. It may take you a few goes to figure out the exact placement so that your vacuum charges properly. Lucky for you, the charging station will chime a little song to let you know that you’ve placed the CordZero in properly.

This is also very important for the self-emptying function because if it isn’t placed properly, then the dirt and dust you’ve just sucked up won’t be cleaned out by the tower.

Does the LG CordZero A9 vacuum cleaner suck?

The short answer is yes, it’s excellent. I’m currently equipped with this $399 Electrolux one and there is a huge difference in the quality of suction and cleanliness.

When in use, it does feel a little off-balance because the head is disproportionately heavier compared to the extension pipe and nozzle. However, it’s still comfortable to grip and easy to wheel around the floors.

I found I had little use for the power mode on my carpet as its normal suction mode was more than sufficient. However, the power and turbo modes are a phenomenal boost if you want to suction deeper into your carpet. Keep in mind that the more power you use, the faster your battery will deplete.

Battery life

Battery life didn’t once concern me. That said, if you’re diligent about placing the LG vacuum back in its charging station after every use, you won’t have much to worry about. I never had to find out if two hours was enough since I was able to thoroughly tackle all of my rooms in my apartment in about 15-30 minutes.

While the extra-long battery life is a welcome feature, if you have a large home you won’t be able to get far without emptying your LG cordless vacuum after a few rooms. Especially, if you have pets. While the tower does eliminate the task of manually emptying the bag, you still need to shuffle back to the charging station, prop it in place then wait for the tower to suck out all the dust before you can continue.

Now, this wasn’t an issue for me with my apartment, since I could use the handy LG Kompressor to push back the cat fur and dirt in order to fit more in. But if you were hoping that not emptying the bag would save you time, you’ll be sorely mistaken.

The tower

When you’re all done expunging the dirt from your floors, you get to witness the fun part. By returning the LG CordZero to its tower, wait for the beep and then listen as a hurricane starts to ramp up inside the charging station. In other words, the self-cleaning process is very loud (and very frightening for my poor kitty).

Although, it is fun to watch as the dust bunnies vanish. But you’ll need to watch out if you’ve filled the vacuum to the brim, as you may need to re-activate the emptying function to fully empty it.

How good is the mop?

Meanwhile, the mop nozzle is quite handy if you’re looking for a quick-drying job. Easy to assemble, all you need to do is switch the nozzles, wet two of the velcro mop heads and stick them onto the nozzle.

I did find that the mop function wasn’t as effective at removing stains on the ground, primarily due to the low rotation speed of the mop nuzzle. Even if you give it a boost with the turbo mode, it takes a bit of hovering in one spot to effectively remove any stains off your tiles.

Emptying the tower

While the manual suggests that you can replace the dustbag around every three months, I found that after using the LG CordZero A9 for a month that my bag was already ready to be replaced. The bag itself is quite small for such a tall tower, and I honestly expected it’d be bigger.

Like any bagged vacuum cleaner, this means you’ll have to buy replacement dust bags every so often. Taking into consideration that a three-pack bundle for the tower costs $59, if you need to change your dust bag every month it will get costly for those on a budget. However, you can go to your local Domayne or Joyce Mayne who stock the three-packs much cheaper at $29.

That said, the convenient part about having a dust bag is that you don’t have to carefully tip your LG stick vacuum over the bin while hoping that every dust bunny doesn’t end up being sniffed up by your nose.

The final verdict

Okay, let’s talk price. Now that the LG CordZero A9 is out in the world, it’s currently selling for an eye-watering RRP of $1,919. Do I love the LG cordless vacuum? Yes. Would I get one? Yes, but not for that price tag. My cat? She’s on the fence.

Overall, this is a fantastic vacuum cleaner and my carpet looks professionally cleaned every time I use it. In fact, I would argue it rivals most Dysons. Personally, I don’t think I could justify spending just over $1,900 on it. You’ll also need to take into consideration whether buying replacement dust bags is part of your budget. After all, the reason why most people turn to a stick vacuum in the first place is because of its portability as well as the affordability that comes from forgoing the dust bags that traditional vacuums use.

But hey, if you’ve got the spare cash and you’re tired of emptying your stick vacuum every time you use it, then go ahead and drop your hard-earned cash.

Where to buy the LG CordZero A9 vacuum cleaner

You can buy the LG CordZero A9 from LG Australia here for $1,919. This model is referred to as the A9T-Ultra and is only available in the colour Iron Gray.

There’s a slightly cheaper model known as the A9T-Auto that you’ll see around in most Australian retailers, which comes in the colour Calming Beige. While they do appear similar, the only differences between the two include a variation of tools, but notably the A9T-Ultra’s Power Drive mop.

It’s not too much of a big deal if you’re happy to continue with your regular mop and bucket, but if you’re sold on this feature, then it’s worth upgrading to the A9T-Ultra.

Here’s where you can grab the A9T-Auto in Australia:
