Cordless vacuum cleaners have grown up. LG’s new CordZero A939 is no longer just a clean accessory, it’s powerful, durable and flexible enough to become your daily necessities, not just on the edges. However, for maximum convenience, this $999 vacuum cleaner and its powerful all-in-one tower base station is expected to empty itself.
It fits neatly into the top of the LG CordZero series, which currently sells for $399. The entire series is equipped with functions such as interchangeable batteries, multiple accessories, and five-step filtration, but just as you would expect from a high-quality A939, the A939 adds some extra details.
The key is the new all-in-one tower. This is a system that absolutely requires room space: a relatively small footprint-with a movable floor, which adds greater stability-but it is very tall, nearly 40 inches. Folding side hooks not only increase the width when fixing tools such as electric brush heads, but the way the door opens means you also need to consider a total width of about 18 inches. I hope that for all tower sizes, LG has also found a place to put spare vacuum bags.
However, just like kitchen appliances, useful household appliances justify the space they occupy. In this case, the biggest selling point is LG’s two ways to minimize headaches by emptying the dust. One of them is familiar to previous CordZero vacuum cleaners, and the other is brand new.
The former is Kompressor, which effectively squeezes the contents of the trash can through a sliding rod on the side. LG said that in this way, you can get more than twice the effective capacity of the trash can without loss of suction.
However, the latter is brand new. The All-in-One Tower is both a charging station for CordZero and a way to empty it. Dock the vacuum cleaner in front, then automatically or manually (if you want) it will open the dust box, suck the contents into the second larger trash can in the tower itself, and then make the A939 ready to be used again .
This is the system we have seen on some robot vacuum cleaners, but it also makes sense for cordless vacuum cleaners. After all, you usually have to choose between larger bins to increase the time between emptying, while smaller bins are lighter and easier to handle. Not to mention the fact that the traditional trash can is dumped on top of the trash can usually end up leaving a lot of floating dust.
In LG’s case, in addition to CordZero’s own filtration, there is a 3-step filtration system in the tower-a removable and washable pre-filter and HEPA filter at the bottom. LG said that one of the one-piece tower bags can fit up to six compressed trash cans, totaling nearly 34 ounces; one box has three boxes, and the subsequent three boxes are priced at $19.99.
Honestly, having to replace disposable bags—not to mention the environmental impact compared to plastic bins that you can empty—makes me stop. LG told me that it has tried paper bags, but found that they may not be as strong as the vacuum required to completely empty the CordZero trash can. LG’s design at least does make the entire replacement process simple and clean: the same tab that you pull to remove the entire bag can also cover the lid.
You can reorder replacement bags through the LG ThinQ app-including setting up a subscription for them, although not based on your actual usage-this will also remind you when to clean the various filters in the tower and the vacuum cleaner itself. The latter has a washable HEPA filter on the lid, a washable pre-filter, and the cyclone separator in the trash can also be cleaned.
LG includes two batteries, one is charged inside the CordZero and the other is under the cover of the base station. At the lowest power setting, the battery life using both can be up to 120 minutes. In the middle setting, you watch 80 minutes together; in Turbo mode, this drops to only 14 minutes. It takes 3.5 hours to fully charge, and the all-in-one tower prioritizes the battery in the vacuum cleaner.
As for the suction power, LG overturned people’s expectations that cordless vacuum cleaners must be lower than power-powered models. Considering the amount of hair she shed every day, my cat is not bald, which is a constant source of surprises, and keeping the top of the hair on tile, hardwood, and carpet floors can be a chore.
The low-power mode is perfect for walking around and doing typical cleanup tasks. The middle setting is more similar to a traditional vacuum cleaner; I have saved Turbo mode for particularly tricky scenes, such as removing burrs from the entrance mat.
Unlike most cordless vacuum cleaners, LG’s handle has a lockable power button: you don’t have to keep pressing the trigger to make the motor run. This is a good convenience feature, although it does work, because I have confidence in the battery life of LG.
Most of the time I have always insisted on using LG’s detachable extension tube and standard electric brush head. My only complaint is that the latter is a bit tall; depending on how high the base under your kitchen cabinet is, you may find it stuck. Some competitors’ vacuum cleaners have low-profile heads.
LG also includes Power Mop, which is an optional accessory for its cheaper cordless vacuum cleaner. It has a pair of removable, washable cushions-fixed with Velcro; there are four in the box-and you can choose to spray water from the top refillable water tank. Replacement pads are priced at $19.99 per set, but LG said it is expected to last “for many years,” depending on the roughness of the floor.
Mopping tiles is a task I don’t like, but Power Mop does help. It may take some trial and error to get the pace right: moving too fast, you will miss the patch, but walking too slowly, automatic spray (with two settings, as well as off) may make the area too wet.

Otherwise, there is a universal nozzle, an electric mini nozzle, a combination tool and a crevice tool. They are easy to get in and out, whether directly connected to the vacuum or via LG’s telescopic rods. This adds another 9.5 inches of coverage.
What price is really convenient? US$999 is not only expensive for cordless vacuum cleaners, but also very expensive for vacuum cleaners. When you can buy an unbranded model for less than $200, can LG really be worth five times the price?
Of course, the reality is that you really have to appreciate and cherish these things, such as not having to empty CordZero’s trash every time you use it, long running time and a full set of accessories. If you just want to quickly tidy up the stairs or around the home office, the cheaper model may succeed. However, I think CordZero can actually replace your existing vacuum cleaner and is your only vacuum cleaner.
The 10-year motor warranty helps justify it, and so does the flexibility of Power Mop. Even so, I suspect that most people will be satisfied with LG’s products at a more affordable price-even if they missed the smart all-in-one in the process. With the development of vacuum cleaners, LG CordZero A939 is top-notch, but you really have to take cleaning seriously to justify this new flagship product.
