Picking the right vacuum for your home is all about figuring out how you want to use it and your particular likes and dislikes about the chore of vacuuming. The other thing about vacuums that changed in just the last couple of years is that design is becoming a much bigger player in this decision. More and more, vacuums are being built to be more attractive, and stored out in the open, as opposed to stuffed in a closet. Plus, as more of us are more germ conscious, there’s also a movement toward designs that enable more hands-free and sanitary emptying. Case in point, the new LG Cord Zero stick vacuum.

In this review I’ll test this vacuum for myself in my home: I was able to secure a loaner from LG for two weeks so I’ll tell you what it’s like to use, about its special features including its All in One Tower, how the accessories work and if overall I can recommend this stick vacuum to you. I’ll also give you a hint that if you have a lot of hard floors, you may want to read this review thoroughly before you buy.

What is LG Cord Zero?

LG Cord Zero is a small to medium-sized cordless stick vacuum that comes with an auto-emptying base known as the All in One Tower.

You could say the LG Cord Zero is a vacuum that strives to reduce as much human effort as possible. LG’s naming of the vacuum doesn’t quite do it justice because having really only refers to the basic level of convenience of a stick vacuum and many brands already make “zero-cord” vacuums. Instead, LG touts this cordless vacuum as having extended battery life and extra quality-of-life enhancements like automatic dustbin emptying via the included docking station.

The LG Cord Zero also has detachable accessories and you can use it as a handheld vacuum as well, which you could also say is table stakes when it comes to premium stick vacs too.

What’s in the Box?

The Cord Zero motor unit is a decent size and well-balanced with a smart locking button that sits right by your thumb for easy access.

The LG Cord Zero comes with two primary cleaner heads for floor vacuuming – the larger universal power nozzle for carpets and hard floors and the power mini nozzle for vacuuming tighter spaces such as chairs and furniture.  Both heads can be connected to the vacuum using the 9.5-inch telescoping extension tube (which makes the vacuum’s reach from about 28 inches from the motor to 38 inches), or plugged right into the motor unit.

The Cord Zero also comes with a crevice tool which you can use in conjunction with the vacuum’s Turbo mode to clean pet hair from tight areas as well as dust from corners.

Finally, you get a combination tool which can act as a shorter and wider crevice tool with a built-in brush attachment if you prefer.

You also get two batteries with your vacuum. One is stored in the vacuum motor and the other is inside the base station.

LG All-in-One Tower

LG Cord Zero review

Charging the LG Cord Zero involves setting it into the included docking station which LG refers to as the “All-in-One Tower.”

This dock is rather large because there’s a lot going on with it.

It houses its own storage compartments for the nozzles in hidden doors on each side of the station, as well as a dedicated area where you insert LG’s proprietary and disposable vacuum dust bag where the vacuum automatically unloads collected dust and debris. Out of the box, you get 3 of these tower bags free and you must purchase more after you run out for around $19.99 CAD for a pack of 3.

The tower has a clean and commanding look compared to typical docking stations. It is at once both extremely clever and somewhat frustrating.

First the clever: everything you need for the vacuum can be hidden inside to maintain that streamlined lock, and to keep from misplacing accessories. Doors open on either side of the docking station to reveal the storage for your accessories. Under the top lid is a smart compartment to keep your extra battery fully charged. Then, using a door in the bottom of the station you can access the vacuum bag. While it’s clever and holds everything, it does actually seem like there’s a lot of wasted space.

Now, the frustrating: the doors don’t open fully. They kind of only open on a 45° angle so they can be a bit awkward to take things in and out of. They also don’t stay open and constantly try to swing partially closed, which can be extremely annoying when you’re trying to put things away.

The station also seems larger and heavier than it should be for what it’s doing. It also has a small revolving panel on each side where you can either leave it alone for a clean appearance or swivel to reveal hooks for holding the nozzles.

Keep in mind that LG also sells other Cord Zero variants that may include other accessories such as a mop kit. However, the one I’m reviewing (A937KGMS) doesn’t include this.

Long emptying time

I found the All-in-One Tower takes a good amount of time to do its auto-emptying task. Frustratingly long if you need to empty the vacuum, but less of an issue if you’re done with your task.

You’ll stick the vacuum in its cradle and push down to lock it in place. Press the start-stop button on top of the station to begin the auto-emptying process. It takes about 10 seconds for the machine to recognize the vacuum is in place and to begin the auto-empty cycle. Fully auto-emptying the vacuum canister takes a further 20 to 25 seconds before it is unlocked and released for you to use again.

Key Features

LG is probably not the first brand you’ll think of when you are seeking cordless vacuum cleaners so it needs some unique features to separate itself from the highly competitive pack. The good news is that the LG Cord Zero offers a few interesting technologies.

Kompressor Technology

The difficulty in designing a cordless vacuum is to make it light enough to be versatile without sacrificing features. This is why most of them have smaller canister sizes for storing dust and debris and the LG Cord Zero is no exception.

However, the Cord Zero vacuum features a special lever you can press to compact the dirt inside the dustbin, allowing it to store about three times its physical capacity. LG calls this technology Kompressor and it allows you to vacuum more and take fewer trips to empty the bin. This also doubles as an effective way to keep the suction power more consistent as vacuums tend to reduce in performance as the dustbin fills up.

How well does LG Cord Zero clean?

LG Cord Zero test

I tested all my vacuums mostly the same way; I will spill things like finer flour or sugar, middle size beds like rice or oats, and larger cracker pieces to see how it performs on both carpet and hard floors.

Kindly, LG also sent a few packages of other spills for me to test out including large size plastic glitter and breadcrumbs.

On carpet, the Cord Zero performed very well. On hard floors it was another story.

In my carpet vacuum tests the Cord Zero picked up everything, mostly in a single pass. From finer sugar to big plastic glitter, it was able to gobble up all my test spills. Only in a couple cases did it need to go over an area more than once.

Works well on flat rugs

In some of my other reviews I have experienced difficulty with other vacuums getting caught up on some of the flatter rugs I have in my home. In particular, Dyson stick vacuum’s tend to catch on my Ruggable rugs and the motor head shuts down and needs to be restarted.

I’m glad to say the Cord Zero absolutely no difficulties with flatter runs, and didn’t seem to get caught up in them at all, nor did they stall out while running.

Terrible on hard floors

On my tiled kitchen floor, the vacuum was a major failure. On each of the tests using the included debris LG supplied for me, the vacuum simply pushed most of the spills away from the cleaner head, creating small piles at the end of each stroke. It took multiple passes before I was able to get all the debris vacuumed up.

When it came to the glitter, the vacuum made more of a mess with that than it did to clean it up. It spread and scattered the small plastic pieces all over the floor, and in some cases the whirring roller brushes also shot pieces a great distance.

I was actually pretty shocked at how poorly this vacuum was at cleaning floors. I dug into the manual to see if it offered any clues, and found a small insert that references when cleaning debris that may be subject to static electricity, to first use the crevice tool or other nozzle attachment. So I tried that and it wasn’t much better. I will say that needing to use two different attachments to clean up one type of spill is more work than I think you should have to do it comes to helping your vacuum.

Comparing LG to Dyson: a rare face-off

Curious if it was just the type of glitter that was a bear, I decided to do something I don’t normally do in a dedicated review… and that’s run a vacuum side by side against its competitor, in this case, the Dyson Gen5 Detect.

To my surprise, the Dyson picked up the entire glitter spill, while the CordZero continued to struggle.

In short, I have to say I’m really surprised by this poor performance.


LG Cord Zero review

I also tested out this vacuum on several pieces of furniture including my sofa and a chair. The vacuum seems to do an excellent job of picking up pet hair and dirt from places it tends to connect. Tended to prefer the larger cleaner head just because it was faster, but the smaller cleaner head was also effective.


I’m actually surprised by the quieter operating volume of this vacuum. Even when it’s cranked up to turbo, it’s not overly loud.

Battery Life and Features

A fully charged LG Cord Zero battery will let you use the vacuum for up to about 120 minutes without using any of the powered motor heads 80 minutes with one of those heads attached.

Activating the “Power” mode will cut the battery life in half while the “Turbo” mode maxes out at roughly 12 minutes. While these figures might sound low, the LG Cord Zero comes with that second battery allowing you to swap out the fully drained one and continue vacuuming with the fresh battery.

I can say this vacuum is on par with something like the Dyson Outsize which also offers 120 minutes of runtime across two batteries.

Auto Empty

The practice of having a handheld vacuum automatically empty its load is really an experience worth trying. Yes, the proprietary disposable bag does add to the aftermarket costs but if you are after long vacuuming sessions and less getting your hands dirty, the auto-empty feature really cuts out the hassle.

You can dock the vacuum in either handheld or upright mode to empty and the feature works by letting the tower literally suck out the contents so you have a nice and clean canister ready for the next job. You don’t have to open the container either which means you never expose yourself to the dust. The LG Cord Zero still lets you manually open the dustbin and empty it too, making this feature completely optional especially if you aren’t a fan of buying replacement bags.

When you talk to vacuum, the tower will automatically empty the bin for you. It takes a few seconds for it to register, and you do have to make sure the vacuum handle is securely placed into its cradle. From there it will vacuum out the insides all on its own. I can also say the noise level for this procedure is nowhere near as loud as I thought it might be.

There is a small washable air filter located inside the motor handle. The lead of the canister will simply swivel off and you can wash and/or replace the filter.

Overall review: LG CordZero

LG Cord Zero review

Overall I may as well cut to the chase and say I can’t recommend the LG CordZero, but I’ll spell out why.

The biggest downside is the cleaning performance on hard floors. The Cord Zero pushes dirt around with what appears to be a poorly designed main motorized cleaning head. The All in One Tower’s big, heavy and clunky design overshadows its useful storage. And the flappy doors just add to my distaste.

The dustbin is small and fills quickly and while I appreciate the marketing around the Kompressor compacting, on bouncy pet hair I didn’t find it overly effective.

I also realized that I found the process of auto-emptying to be more hassle than it was worth, since having it return to the base, lock it in place and wait for the cycle to begin, vacuum out the bin and then play the LG chime before it finally unlocks and releases took too long. It was far faster and easier to flip open the bottom of the bin at the nearest trash can and keep going.

So what are the plusses of this machine? Mercifully it’s great at vacuuming carpet. The vacuum itself is lightweight and portable and the easy-to-use locking power button is in a perfect spot.

In short, it feels like LG spent too much time on the looks and not enough time on the core competency; the cleaning.

The LG CordZero sells for about $1049CAD/$999USD and you can get it from places like Canadian Tire and Lowes in Canada or Amazon in the USA. You can also get a version without the Tower for less (About $699CAD) at Walmart.
