LG Kompressor vs Dyson V15, which will be the winner of this tough competition? For me, it is the Dyson V15 because this vacuum has better pick-up performance and utility than its rival.
The Dyson V15 turns out to be a better option for pet owners and those having a mixture of bare floors and carpets in their houses. The strong suction combined with two interchangeable cleaner heads allows the Dyson V15 to deal with small-to-large debris very well. Its detangling brush roller of the motorbar makes the vacuum best for removing pet hairs. The laser light is also useful for cleaning hidden dirt on bare floors.
The LG CordZero Kompressor has a better design convenience for me because it has a one-touch power button, larger dust cup capacity, lower noise level, and a portable charging stand for no hole drilling on the wall. It also comes with two batteries, allowing you to vacuum more with no interruption. However, it can be prone to hair tangling and does not include headlights and a soft-roller floor head for optimizing bare-floor cleaning performance.

LG Kompressor vs Dyson V15: Differences
The Dyson V15 wins 2-1 against the LG Kompressor in terms of cleaning performance and utility. Meanwhile, the LG Kompressor is the better in design convenience.
Cleaning performance
Winner: Dyson V15
The suction of the Dyson V15 is stronger than that of the LG CordZero Kompressor. The measured suction I got for the LG Kompressor is around 75 inches of water lift, while that of the Dyson V15 is approximately 102 inches. The higher suction contributes to significantly increasing the pick-up efficiency, especially on the hard floor.
After several pick-up tests, the Dyson V15 is much better than the LG Kompressor, particularly in collecting pet hair and larger debris on bare floors. On carpets, both of them perform well, and the larger debris picking up is relatively better.
Particularly, when I used these two vacuums to collect the scattered sugar and powder on bare floors and carpets, the Dyson V15 and LG Kompressor can suck all of these things. However, the Dyson V15 is a bit better because it can nearly remove the debris off the carpets in one forward pass. The LG Kompressor needs more passes to give the same result.
With bigger debris like cheerios or kibbles, the Dyson V15’s pick-up performance is better owing to the adjustable gate on its Motorbar cleaner head. Meanwhile, the LG Kompressor pushes the cheerios rather than picking them up.
Additionally, the Dyson V15 includes a soft-roller cleaner head, which is ideal for optimizing the cleaning performance on hard floors as it can deal with both small and large debris. Though the LG Kompressor has a compatible soft-roller cleaner head, you need to buy it separately; and I see that the price of this cleaner head is quite high.
Another thing I like about the Dyson V15 is that its motorbar floor head has a hair-detangling mechanism. Therefore, when using it to remove pet hair on carpets and hard floors, the hair can easily get into the dust bin and does not get tangled on the bristle roller. Such a feature makes cleaning the brush bar less daunting.
The LG Kompressor can also collect pet hair decently, but the hair tangling on its brush roller can be significant. It is because its universal cleaner head does not have a self-cleaning brush roll like the Dyson V15. So, after every cleaning, I have to check the cleaner head and remove the tangled hair off the brush roll to ensure the diction efficiency for the next use.
Dust bin & Filtration
Tie!
One feature unique about the dust bin of the LG Kompressor is its Kompressor technology. The LG Kompressor’s dust cup has a lever for pushing down the dust content inside, making more room to spare. So, compared to the Dyson V15, when vacuuming the house with the LG Kompressor, I don’t have to stop to empty the dust cup in the middle of the cleaning session.
However, I prefer the dust-cup emptying mechanism of the Dyson V15 to that of the LG Kompressor. I need to pull down the lever on the dust cup to get the lid open and release things into the dust bag. Meanwhile, with the LG Kompressor’s dustbin, I have to push the button near the lid, then the dirt gets out, and parts of it stay on my hand.
The filtration systems of both Dyson V15 and LG Kompressor are excellent because all of them are well-sealed multi-stage filtering systems that can filter micro dust particles (up to 0.3 microns) to clean exhaust air.
Design & Convenience
Winner: LG Kompressor
Regarding ease of control, I am more on the side of the LG Kompressor. It is because this vacuum is relatively lighter, easy to maneuver, and features a single-touch power button for a better gripping experience. The single-touch power button is a great factor because, on the Dyson V15, I have to hold down the power trigger for a long period, making my arm tired easily.
Besides, the LG Kompressor has a charging stand that allows you to store and charge the vacuum on the floor without drilling any holes in the walls. Additionally, the LG Kompressor is relatively quiet in operation than the Dyson V15. The noise level I measured at the highest suction is around 75 dB for the LG Kompressor and 82 dB for the Dyson V15.
For battery life, the LG Kompressor is better because it comes with two batteries in the package. Thus, it offers a longer runtime than the Dyson V15. The tested runtime of the Dyson V15 and LG Kompressor in each mode is listed in the following table, you can take a look for reference.
| Dyson V15 | LG Kompressor | |
|---|---|---|
| No. of battery | x1 | x2 |
| Total runtime | Eco: 65 mins Auto & Med: 45 mins Boost: 8-10 mins | Normal: 74 mins Power: 40 mins Turbo: 12 mins |
| Charging time | 4.5 hours | 4 hours |
Utility
Winner: Dyson V15
Headlights
The green laser light on the fluffy cleaner head of the Dyson V15 makes it more advantageous in enhancing cleaning efficiency, compared to the LG Kompressor with no headlights.
For me, the headlight is an essential feature to get a more satisfying cleaning experience, especially when cleaning hard floors. The high-lumen headlight contributes significantly to illuminating dark areas under furniture and revealing small debris that is hard to see with bare eyes. Therefore, I often highly appreciate the vacuums with bright headlights in my comparison.
Intelligent sensors & LCD screen
For me, the standout feature of the Dyson V15, setting it apart from the LG Kompressor, is its piezo sensor. This sensor measures the dust amounts throughout the entire cleaning session. Moreover, the brand claims that in the auto mode, the sensor helps increase the suction power to improve the pick-up efficiency in highly dusty areas.
Furthermore, I find the LCD screen on the Dyson V15 to be superior to the LED display on the LG Kompressor. The Dyson V15’s LCD screen shows maintenance alerts and provides dust reports, in addition to the power modes and runtime countdown. Specifically, the dust report demonstrates invaluable insights in the form of categorized dust sizes and amounts, which is beneficial to keep you well-informed about the cleanliness of your surroundings.
Smart features
The LG Kompressor can connect to the ThinQ app on your mobile phone via a WiFi connection. This is not featured on the Dyson V15. By connecting the LG Kompressor to the app, you can track your cleaning history, diagnostics about your vacuums, and battery life.
