LG CordZero A9 vs. Dyson V15 Detect Comparison

LG CordZero A9 vs Dyson V15 Detect

After comparing the LG CordZero A9 and Dyson V12 Detect, I’ll continue my series on these brands by looking at the CordZero A9 and V15 Detect.

As I’ve mentioned in the previous comparison, the CordZero A9 is LG’s first cordless stick vacuum, and it comes in several sub-variants we’ll look at in a bit.

While LG got its design inspiration from Dyson, it has some unique features absent in the latter, like the stand with a slot to charge the extra battery and a three-button interface for power plus toggling between two power settings.

But how does it compare to the more premium V15 Detect? One of Dyson’s latest releases. I’ve put these products through a grueling series of tests to find out.

Introduction to the LG CordZero A9 and Dyson V15 Detect

LG CordZero A9. vs. Dyson V15 Detect full body

Continuing my series on LG and Dyson, we’ll look at how the CordZero A9 compares to the premium V15 Detect.

Since Dyson introduced the V10 Absolute, they’ve focused their R&D solely on cordless vacuums, and the V15 possesses all the latest features.

This model isn’t the latest with the pending release of the Gen5 Detect, Dyson’s most powerful cordless vacuum to date, but there’s not much variance from what I’ve seen in the advertorials.

Of course, that can change once I get the product and test it, but I’m still waiting for it to be available here before purchasing, so stand by for that review.

Premium, High-Tech: Dyson V15 Detect

Dyson V15 Detect


  • It has all of Dyson’s bells-and-whistles
  • The laser slim roller offers the best-in-the-industry dust tracking with the bright green laser
  • Outstanding range at over 80 minutes (from a single battery)
  • Above-average dustbin bin capacity
  • Excellent at cleaning hair, especially on carpets
  • Lots of interchangeable tools
  • The torque screw tool is highly efficient at cleaning long hair strands (even large quantities)
  • Detachable battery


  • Premium cost
  • Noisy, especially in the boost (or max) setting
  • Hair will stick to the inner walls

Dyson launched the V15 with several groundbreaking features, like the laser slim roller and torque screw tool.

The laser slim roller utilizes an industry-first green laser, illuminating dust and accentuating it better than any LED-equipped stick vacuum I’ve tested.

Dyson V15 green light expose dust particles

Dust is visible without additional lighting thanks to the sharp contrast of green light.

This feature helps make vacuuming efficient – here’s the after photo.

Precisely, it measures four debris sizes and shows the quantity in real-time on the LCD screen behind the motor.

The round silver button toggles between the three power settings (eco, auto, boost).

Below is the Piezo readout is the battery status – how much run time is left.

The next upgrade is the high torque attachment with the same adjustable gates, which now has combs above the brush roll to help untangle hair.

I’ve tested it on hair strands between five and thirteen, and it excelled, picking up a high percentage (more below).

Another attachment that helps it clean hair is the torque screw tool with the tapered brush.

Dyson V15 torque screw brush out

It picked up everything, even large quantities of long hair strands.

The tapered brush funnels hair into a holding area and then into the dustbin – a clever design I haven’t seen.

More Basic: LG CordZero A9

  • Cheaper than the Dyson V15 Detect
  • Same efficient pick-up as the V15 for less
  • Above average with deep cleaning carpets (over 94%)
  • The lightweight frame is very ergonomic
  • It comes with a stand for storage and charging the extra battery
  • Two detachable batteries extend run time


  • Shorter range
  • Fewer tools
  • Noisy

A more basic option is the LG CordZero A9. While it doesn’t have the V15’s bells and whistles, this model is less expensive than its premium counterpart.

You can see traces of the Dyson V8 with its design, like the vertically aligned dustbin, soft roller, and standard brush roll design.

LG CordZero A9 body only 1

But LG didn’t blatantly copy Dyson, and it added its (own) touches.

An obvious one is not using a trigger but a three-button interface behind the handle.

LG CordZero A9 handle controls

This provides consumers easy access to the power switch, and it’s less tiring to use since there’s no trigger to squeeze.

In front of the switches is a 3-LED battery indicator. Not high-tech, but at least you can see the battery status.

It has two separate nozzles for vacuuming hard floors and carpets.

LG CordZero A9 cleaning nozzles

LG designed its version of the soft roller and standard nozzle. The design looks similar to the Dyson V8, but the CordZero’s version is better at cleaning hair on carpets!

These tools compensated for the A9’s low airflow with their high-end agitation and picked up a higher overall percentage than the V12 Detect.

It won’t match the V15 Detect with either surface or embedded debris, but it’s not far off.

And with its lower price point, this variant is something budget-conscious shoppers should consider.

Similarities between the LG CordZero A9 and Dyson V15 Detect

Next, we’ll look at the similarities between these products.

1. Versatility

Though these products don’t look alike, both are versatile enough for cleaning upholstery and floors, thanks to the interchangeable tools.

The CordZero’s lighter frame gives it the advantage over the bulky V15 Detect, making it more ergonomic above floors.

However, Dyson comes with more tools out of the box, and this variant has the latest attachments, like the torque screw tool.

2. Purpose-Built Nozzles

LG CordZero vs. Dyson V15 soft roller

Both have purpose-built nozzles – a soft roller and standard brush roll for cleaning hard floors and carpets.

One variance is peripheral features like Dyson’s laser slim roller.

Dyson V15 accentuates dust

LG’s soft roller is chunkier with the same profile as the Dyson V8. It doesn’t have any additional illumination to help track dirt.

3. Sharp Steering

LG is one of a few brands that match a Dyson cordless stick vacuum steering – specifically, how sharp it turns.

Simplicity S65 steering vs LG CordZero

The photo above shows a side-by-side photo of the LG CordZero A9 (right) and the Simplicity S65 (left).

LG doesn’t turn as sharply, but it’s pretty close.

One disadvantage for the CordZero A9 is its bulky soft roller attachment that won’t fit under low clearance overhangs compared to the V15’s slim profile roller.

4. Battery Detachability

Dyson V15 detachable battery

Both have detachable batteries, enabling consumers to double the run time by purchasing an extra.

Most CordZero options come with two batteries out of the box, but the V15 Detect runs much longer per battery.

Differences between the LG CordZero A9 and Dyson V15 Detect

While these vacuums share the same versatility, there’s a lot of variance with their designs, starting with the dustbin.

1. Dustbin

LG CordZero A9 vs. Dyson V15 Detect dustbin comparison

One of the most noticeable variances between the LG CordZero A9 and Dyson V15 Detect is the dustbin – orientation and capacity.

LG utilizes an older designed vertically aligned dustbin with only 0.399 liters, while Dyson almost doubles that at 0.77 liters.

Another plus for the V15 Detect is the hygienic system, which has a built-in mechanism to push dirt downwards.

Dyson V15 hygienic system

The CordZero A9 doesn’t have this feature, but select variants (A927KVMS) have a debris compactor feature, increasing capacity up to 2.4 times.

2. Power Switch

Dyson V15 trigger

Another variance is the power switch with Dyson’s trigger and LG’s three-button switch.

LG CordZero A9 handle controls

I like LG’s design better because there’s no need to continually squeeze a trigger, which can be tiring when vacuuming for long stretches.

3. Battery Status

Dyson was one of the first brands to introduce a real-time run time status on an LCD screen with the V11, and that trend continues in the V15 Detect, where a timer is shown underneath the Piezo readout.

Dyson V15 LCD close up

Unfortunately, LG doesn’t have this feature but only has a 3-LED indicator showing the battery status, so there’s less precision.

4. Filter and Filtration

Dyson cordless stick vacuums from the V10 onwards use a single-piece filter where the pre and post-motor elements are fused.

Dyson V15 vs V11 Outsize vs V11 Torque Drive vs V10 filter

All its products after the V10 utilize the same design, albeit in differing sizes.

Another aspect going for Dyson is the seals, which are (probably) the best in the industry as they didn’t leak during the fog test.

Dyson V15 fog test

LG’s filter isn’t as thick or the seals robust since there were visible leaks during the fog test.

LG CordZero A9 fog tests

The CordZero A9 utilizes a two-piece system, but the seals aren’t as good.

Here’s a close-up of the primary filter.

LG CordZero A9 main filter 1

And the HEPA filter.

LG CordZero A9 post-motor filter

Only the primary filter is washable with its cloth material, but the HEPA filter is not, so please take note.

Ergonomics Comparison

LG’s lighter body gives it a considerable advantage in this category, despite having the same weight (around 6 lbs).

Most of the CordZero’s weight is at the bulkier nozzle attachment, so that doesn’t affect the handle weight.

The V15’s larger dustbin makes it more top-heavy, and consumers will feel the added bulk when cleaning for longer stretches, especially on carpets where the steering isn’t as light.

Interface Comparison

LG CordZero A9 vs Dyson V15 Detect interface

The photo above summarizes the technological differences between the CordZero A9 and V15 Detect.

LG uses simpler tech with a three-button interface for power and toggling between two suction settings, while the V15 only has a single button plus an interactive LCD screen.

Dyson’s LCD screen provides the Piezo readout, run time status, current power setting, and error codes (if triggered).

It’s more precise, especially with how much run time is left, giving consumers a heads up when to recharge.

LG’s 3-LED battery indicator is decent but not as accurate.

Battery and Run Time Comparison

The V15 Detect wins this category thanks to its larger 3600 mAh lithium-ion battery.

Dyson has improved its battery tech with every subsequent release, introducing more energy-dense versions that run longer.

Dyson V15 Detect
Hard Floor84:19 mins41:30 mins.N/A
Carpet56:58 mins17:23 mins11:02 mins
LG CordZero A9
Cleaning Nozzle43 mins.N/A15 mins

While LG runs longer, combining the two batteries (86 minutes), the V15 Detect is much better per battery (84++ mins).

Another advantage is the middle setting, where a sensor boosts suction when it detects more debris.

However, LG runs further in the max setting (15 vs. 11 mins), which is a big surprise for me during the experiments.

Airflow Comparison

Next, we’ll look at airflow, where I use an anemometer to check air turbulence flowing through the wand and nozzle.

It indicates how well a cordless vacuum will clean, especially on carpets.

Here are the results for the LG CordZero A9 and Dyson V15 Detect.

LG CordZero A9
Wand31 CFMN/A52 CFM
Cleaning Head24.53 CFMN/A36.32 CFM
Dyson V15 Detect
Wand34.55 CFM42.38 CFM73 CFM
Cleaning Head29.98 CFM36.32 CFM69.19 CFM

There’s a noticeable variance between these cordless vacuums. Dyson has (more than) 33% more at the extension tube and a whopping 62% more at the nozzle.

This variance is seen (mostly) in the carpet cleaning experiments where the V15 Detect excels.

Cleaning Comparison

ModelDyson V15 DetectLG A9 CordZero
Hard Floors (Surface Test)99.85%99.7%
Sand on Hard Floor99.8%100%
Carpet (Surface Test)100%99.95%
Deep Cleaning100%94.75%

Despite the airflow variance, there isn’t much disparity between the CordZero and V15 Detect with vacuuming experiments.

The LG CordZero held its own, especially with surface debris tests, where it picked up in the high 90s.

Which is better on hard floors?

One metric I use is the sand on hard floor test, where the CordZero got a higher score – albeit only 0.2% better.

Here’s a before and after shot for the LG CordZero A9.

And the Dyson V15 Detect.

Dyson V15 sand on hard floor

There’s not much variance with the eye test as these products got nearly everything.

In my opinion, the 0.2% difference is negligible, and both nozzles are highly efficient at debris pick-up, even a difficult one like sand.

Consumers should look at factors like roller size and whether they need the green laser for tracking dust.

Hair Wrap Comparison [on Hard Floors]

Next, we’ll look at how these products fared with cleaning hair, starting with the V15 Detect, which was excellent despite not having any active anti-tangle system.

  • 5-inch: 100%
  • 7-inch: 100%
  • 9-inch: 100%
  • 11-inch: 100%
  • 12-inch: 80.6%

The V15 slim roller was excellent at picking up hair, even long strands above nine inches, except for twelve-inch strands where hair wrapped on the roller and axle.

  • 5-inch strands: 98%
  • 7-inch strands: 81%
  • 9-inch strands: 86%
  • 11-inch strands: 86%

LG didn’t do as well, only picking up in the 80s with hair strands above five inches. The low airflow is a factor in these tests since both products don’t have an active anti-tangle system.

Edge Cleaning Comparison

There’s not much variance between the LG CordZero A9 and Dyson V15 Detect, as both picked up efficiently.

Here’s a before and after shot for the CordZero A9.

The eye test confirms this, as both got everything from this area.

Which is better on carpets?

The Dyson V15’s higher airflow is a huge factor in why it was better on this surface.

It got a perfect 100% on surface debris and embedded sand, even in the middle setting for the latter, while the CordZero A9 only got 94.75% – a decent score given its airflow limitations.

Hair Wrap Comparison [on Carpets]

Dyson’s upgraded brush roll with the combs and chunkier brush roll gives it a significant advantage over most cordless stick vacuums, along with the airflow variance.

It was (almost) perfect at picking up hair, even long strands.

Dyson V15 hair wrap on carpet

  • 5-inch strands: 100%
  • 7-inch strands: 100%
  • 9-inch strands: 100%
  • 11-inch strands: 99%
  • 12-inch strands: 98%

Even with long eleven and twelve-inch strands, it got nearly 100%, which bodes well for pet owners, factoring in the torque screw tool’s efficiency.

Surprisingly, LG was excellent, also picking up in the high 90s and 100s in all the experiments.

  • 5-inch strands: 99%
  • 7-inch: 100%
  • 9-inch: 100%
  • 11-inch: 99%

There wasn’t much visible hair wrap on its chunky brush roll, so kudos to LG for this feat.

Noise Comparison

ModelLG A9 CordZeroDyson V15 Detect
Low72.0 dB70.3 dB
Auto/MidN/A72.5 dB
Max79.4 dB80.8 dB

Even with the airflow disparity, there isn’t much variance with noise. The V15 Detect is (obviously) the noisier option, but the LG CordZero A9 isn’t far off – only a few decibels difference.

So it’s a win for Dyson in this category, even if it’s (technically) louder.

Dyson Versus Other Brands


All cordless stick vacuums need maintenance to function efficiently for years.

You’ll be spending (easily) a few hundred for these products, and caring for them makes sense to ensure these machines last as long as possible.

  1. Primary nozzles: This component is the most abused and needs the most frequent maintenance – at least weekly. Fortunately, these brushes are detachable and straightforward to clean. Remove dust and hair build-up, especially on the axles, to prevent premature wear.
  2. Dustbin: Empty the contents after every run to prevent debris from clogging the filter and dust mites from breeding.
  3. Filter: Clean the primary filter once a month to maintain performance.
  4. Battery: Avoid using the max setting for extended periods to lengthen the battery’s service life. Using it in this setting overheats the battery, shortening its lifespan.

These products are available in online stores like Amazon. Check the links below for the latest pricing information.

Disclaimer: I’ll earn a commission if you purchase through any of the links above, but at no extra cost, so it’s a win for us!

Which offers the better value?

The answer will depend on the price variance, which can vary depending on the season.

If it’s below $100, I’d bite the bullet and spend more for the Dyson V15 Detect because it comes with more technology, runs longer, and is better at cleaning carpets.

Otherwise, LG’s cleaning performance is decent for consumers who want something cheaper and do not mind the simpler technology.

5 Reasons to choose the Dyson V15 Detect

  1. More technology: The V15 Detect is packed with more technology like the Pieze sensor, laser slim roller, and LCD screen than the more basic CordZero.
  2. Runs longer: Its energy-dense lithium-ion battery will run longer (over 84 mins) per charge, nearly doubling LG’s output.
  3. Better carpet cleaning performance: The V15’s higher airflow enables it to clean carpets better, even embedded sand at the auto (or middle) setting.
  4. Tracks dust: The laser slim roller’s green light embellishes almost-invisible dust particles better than any LED-equipped stick vacuum.
  5. Torque screw tool: This attachment is highly efficient at cleaning long hair strands on fabric upholstery.

Reasons to choose the LG CordZero A9

  1. Cheaper option: The CordZero A9 is less expensive than the V15 Detect.
  2. Above-average cleaning: Despite the lower airflow, the CordZero A9 picks up debris well and is not far off the V15.
  3. Two batteries: Most sub-variants come with two batteries, mitigating the shorter run time per battery.
  4. Good at cleaning hair: LG’s standard brush roll is (surprisingly) excellent at picking up long hair strands, with only a few strands wrapping on the brush roll above nine inches.
  5. Storage stand: It comes with a stand for storing the vacuum vertically (plus tools) and a slot for charging an extra battery.

The Verdict: Dyson Offers More Value

Despite being the more expensive option, the Dyson V15 Detect offers more for your dollar.

It has Dyson’s latest technology: Piezo sensor, laser slim roller, interactive LCD screen, real-time data for run time and debris counter, and more.

If the price variance is around $100, even $150, I’d go with the Dyson because it performs better, especially at vacuuming carpets with its higher airflow.

LG’s option isn’t bad. It’s quite good for a first product.

Consumers will enjoy efficient cleaning performance on hard floors and carpets for less than a premium cost.

The lighter frame makes it more ergonomic as a handheld, but it won’t be as good at cleaning carpet for longer stretches.

So you’ll have to weigh what to prioritize and budget.
