Miele Triflex HX1 vs. Dyson V12 Detect

Miele Triflex HX1 vs. Dyson V12 Detect

Continuing my series on Miele and Dyson, we’ll compare the Miele Triflex HX1 and Dyson V12 Detect.

Unlike the V15 Detect, priced at the premium level, the V12 Detect is cheaper, thus, making this comparison closer than the previous one.

One critical variance with the V12 and V15 is the airflow, which translates to worse deep cleaning performance. So the Triflex is closer to this model than the V15 Detect.

Introduction to the Miele Triflex HX1 and Dyson V12 Detect

Unlike the Dyson V15, priced over the premium threshold, the V12 Detect is cheaper but has a smaller dustbin and lower airflow output, dragging it closer to the Miele Triflex HX1.

Miele formerly only manufactured bagged vacuums, but the HX1 changed that narrative, and it’s the first Miele bagless product.

I don’t blame them since cordless bagless vacuums are more popular than their bagged counterparts, so Miele wanted a piece of the multi-billion dollar pie.

Self-Standing Convenience: Miele Triflex HX1

Miele Triflex upright configuration


  • Self-standing convenience
  • Bigger dustbin capacity than the V12 Detect
  • Above-average deep cleaning performance
  • Detachable battery
  • Decent run time without the standard nozzle (over 60 mins)


  • Short run time with the primary nozzle (around 30 mins)
  • No soft roller attachment (subpar on hard floors)
  • Poor hair cleaning performance

Instead of copying Dyson’s framework, Miele went in another direction for its first cordless stick vacuum.

As its name implies, the Triflex is unique; consumers can use it in three configurations.

The first is putting the dustbin container on top in a traditional stick vacuum setup.

Miele Triflex deep under furniture

This configuration offers better reach underneath furniture but at the expense of the top-heavy feel.

Next and my favorite setup is the handheld frame in the middle, providing the best ergonomics for cleaning floors and (also) enabling it to stand on its own.

Lastly is the handheld configuration – my least favorite because of its sheer bulk and handheld placement, making it unusable for long stretches.

Miele Triflex HX1 handheld configuration

The Triflex’s cleaning performance is adequate on carpets but subpar on hard floors because it doesn’t have a soft roller nozzle.

It can vacuum small debris but will snowplow large dirt piles. Also, the brush doesn’t have adequate agitation on hard floors.

The only reason I recommend this option is its carpet cleaning performance, which is above average.

Lighter and More Technology: Dyson V12 Detect

Dyson V12 Detect slim roller


  • Lightweight and ergonomic
  • Better steering than the Miele Triflex
  • Longer run time (over 60 mins with the soft roller)
  • More tools out of the box
  • The laser slim roller accentuates almost invisible dust
  • Excellent on hard floors
  • Above average at cleaning long hair strands


  • Small dustbin volume (0.35-liters)
  • No self-standing feature

The V12 Detect represents a zag in Dyson’s product development.

Before testing it, I thought it was a variation of the V15 with a push-button switch, but it’s not.

This model is a lighter version of the V15, geared towards mobility and ergonomics rather than power and volume.

Dyson V12 vs. V15 Detect dustbin alignment

You can see the massive size variance in the photo above.

There will be compromises with the downsized frame, particularly with dirt volume and power.

However, the V12 isn’t meant for deep cleaning carpets but for cleaning smaller spaces with its more compact frame.

One significant advantage of the V12 over the Triflex HX1 is its technology. A myriad of features in it are not available in Miele.

The Piezo sensor readout behind the motor is the most obvious, showing debris size and quantity.

Dyson V12 vs. V15 Detect interface

It’s similar to the V15 but on a smaller screen.

The screen also shows the run time status and potential error codes.

While these features are excellent, they aren’t the most helpful ones. That distinction goes to the laser slim roller.

Dyson V12 laser slim roller dust

This tool is (probably) the best at accentuating dust compared to an LED-equipped stick vacuum.

This will make vacuuming hard floors more proficient because it helps track which areas need cleaning (and otherwise).

Since it has a soft roller nozzle, the V12 Detect is better than the Triflex HX1 for cleaning hard floors.

Add its lightweight design, and it’s the no-brainer option for this surface.

On carpets, it’s closer, but the variance is negligible.

Similarities of the Miele Triflex HX1 and Dyson V12 Detect

Next, we’ll examine the similarities between these two very different options.

1. Versatility

Dyson V12 handheld configuration

These options are versatile in various configurations as a handheld or stick vacuum.

Dyson is the more versatile option overall, but Miele has more configuration alternatives with the handheld frame on top or middle to enable the self-standing feature.

The V12 Detect is better because of its sleeker and lightweight frame. It’s much better in its handheld configuration than the Triflex HX1.

2. Detachable Battery

Dyson V12 battery

Another similarity is the detachable battery. The Miele Triflex HX1 and Dyson V12 Detect batteries are detachable and have chargers that can charge them outside the vacuum.

So it’s possible to purchase an extra battery to extend the run time.

Differences between the Miele Triflex HX1 and Dyson V12 Detect

Next. We’ll examine the differences between the Miele Triflex HX1 and Dyson V15 Detect.

1. Framework

Like the previous comparison between the Triflex HX1 and V15 Detect, these products have varying designs.

The V12 Detect utilizes Dyson’s traditional framework with the handheld frame on top, while Miele has more configuration options (handheld frame on top or in the middle).

One advantage for Miele is it has a self-standing feature in one of those configurations, but Dyson offers better steering, especially in cramped spaces.

2. Brush Roll

Most (if not all) V12 Detect variants come with two brush roll options – the laser slim roller and the standard brush roll.

Dyson V12 floor nozzles

The Miele Triflex HX1 only comes with a standard brush roll attachment.

One issue with this tool is its low profile opening, so it snowplows large dirt piles.

Its brush design also lacks agitation and is inefficient on hard floors.

3. Dustbin Design

Another difference is the dustbin design. Miele has the larger capacity container at 0.5 liters, while the V12 Detect only has a 0.35-liter volume.

Miele Triflex dustbin and filter

But I like the V12 design better since it has a hygienic system that pushes debris downward.

4. Tools

The Dyson V12 Detect has more tools and attachments out of the box. It comes with innovative tools like the torque screw and laser slim roller tools.

Dyson V12 tools

Miele doesn’t have this type of variety and has a simpler toolset – one upholstery, crevice, and round brush tool.

Miele Triflex handheld tools

Another advantage of the V12 Detect is some models come with two batteries and two chargers so that consumers can charge the batteries simultaneously.

6. Filtration

Dyson V12 fog test

All Dyson products I’ve tested, except for the V7 MotorHead, have sealed systems, meaning these products don’t leak during the fog test.

Miele, despite its claim, doesn’t have a sealed system since it leaked (albeit slightly) during this experiment.

Ergonomics Comparison

Despite the Triflex’s upright ergonomic feel, the V12’s lighter frame gives it a distinct advantage in this category.

The compact frame, smaller motor, and ball system significantly differ with steering and handle weight, which means consumers can use it for extended stretches without fatigued arms.

It has a sharper turning radius, and the more compact nozzle will fit in cramped spaces better than Miele’s bulky brush roll.

However, one of Miele’s configuration options (dustbin container in the middle) works great for cleaning open spaces.

Its steering is adequate but doesn’t have the turning radius of a Dyson.

Interface Comparison

Another disparity between Miele and Dyson is their interface.

Dyson V12 Piezo sensor

The V12 Detect utilizes a more modern interactive screen with the Peizo readout and batter status, showing how much run time is left. In contrast, the Triflex HX1 uses a slide switch and three-LED battery indicators.

Miele Triflex HX1 handle controls

So the advantage goes to the Dyson V12 Detect in this category.

Run Time Comparison

Dyson V12 Detect
Hard Floor63:00 mins.37:50 mins.N/A
Carpet42:00 mins.27:31 mins.6:25 mins.
Miele Triflex HX1
Cleaning Nozzle30:06 mins21:03 mins16:18 mins
Non-powered tools62:43 mins24:28 mins17:33 mins

Both options use the same rated 2500 mAh lithium-ion battery, but Dyson’s version runs longer per charge.

If you’re familiar with the Dyson brand, they spend a lot on battery R&D, and even with the “small” capacity output, it has an excellent range at 63 minutes with the soft roller on hard floors and 42 mins on carpets (using the standard nozzle).

Unfortunately, the Miele Triflex HX1 doesn’t have this extensive range, only lasting 30 minutes with the primary nozzle and over 62 minutes with a non-powered attachment.

Decent, but compared to the V12 Detect, it’s not close.

Airflow Comparison

Next, we’ll check how the Miele Triflex HX1 and Dyson V12 Detect compares with airflow.

Miele Triflex HX1

Cleaning Head35.88 CFM41.91 CFM45.75 CFM
Dyson V12 Detect
Wand27.43 CFM32.23 CFM58.74 CFM
Cleaning Head24 CFM28.52 CFM48.38 CFM

The airflow results between Trifflex HX1 and V12 Detect are much closer than with the V15.

Miele has the advantage in the low and middle settings, while the V12 Detect was better in the max setting, which is a good sign for Miele, at least for vacuuming carpets.

Cleaning Comparison

ModelDyson V12 DetectMiele Triflex HX1
Hard Floors (Surface Test)99.8%77.75%
Sand on Hard Floor99.9%100%
Carpet (Surface Test)99.45%99.77%
Deep Cleaning94.1%93.9%

These results are closer than the numbers suggest. The poor Quaker oats result (only 12%) skewed the Triflex HX1 scores pick up, but it was decent with the other experiments (between 99% and 100%).

So If you based it on these figures outside Quaker oats, it’s still a viable option on hard floors.

But there are other factors to consider.

Which Option is Better on Hard Floors?

Surprisingly, even without a soft roller tool, the Triflex HX1 was better at picking up sand (100% vs. 99.9%).

But I’d still recommend the V12 Detect on this surface because it’s more efficient (with the soft roller tool) and has the green laser – beneficial for tracking dust.

Another plus for Dyson is its ball steering and compact nozzle, so it’s better in tight spaces, whereas Miele has a bulky frame that’ll struggle in these areas.

Hair Wrap [on Hard Floors]

The Dyson V12 Detect is the better option for cleaning hair with its higher airflow in the max setting, which manifests in the results.

  • 5-inch strands: 96%
  • 7-inch strands: 100%
  • 9-inch strands: 92.5%
  • 11-inch strands: 98%
  • 13-inch strands: 100%

These are better than expected results for a tool without an active anti-tangle system, meaning it doesn’t have a comb for untangling strands.

However, one weak spot for the V12 Detect is hair wrapping on the axles since there’s a noticeable gap.

The Miele Triflex HX1 didn’t do as well. You could see visible strands wrapping on the brush even with shorter seven-inch hair.

Miele Triflex hair wrap on hard floors

  • 5-inch strands: 98%
  • 7-inch strands: 84%
  • 9-inch strands: 53%

The biggest culprit is the thin brush with stiff bristles, which lacks an anti-tangle system.

Don’t rely on this product to vacuum hair (pet or human), specifically long strands.

Edge Cleaning

There’s little difference with edge cleaning for the Miele Triflex HX1 and Dyson V12 Detect.

Both are efficient, needing only a few passes to vacuum debris from this area.

Here’s a before and after shot for the Miele Triflex HX1.

Which Option is Better on Carpets?

The gap between the Triflex HX1 and V12 Detect is narrower on this surface, but the latter has a slight edge since it has more airflow at the max setting.

It was better in the deep cleaning experiments, picking up (a tad) higher (94.1% vs. 93.9%), but the variance is too minimal to consider either the outright winner.

Also, the results on surface debris experiments are very close (99.77% vs. 99.45%), with the Triflex HX1 getting higher averages, so it’s a toss-up.

Deep Cleaning

The deep cleaning results are incredibly close – only a 0.2% variance (94.1% vs. 93.9%), so it shouldn’t be a deciding factor between these products.

Consumers should consider other factors like dustbin capacity, features, and ergonomics to determine which option is better.

Hair Wrap [on Carpets]

Like on hard floors, the Dyson V12 Detect is better at cleaning hair on carpets. It picked up a higher percentage and resisted tangles better, even with long hair strands.

Dyson V12 hair wrap on carpet

  • 5-inch strands: 100%
  • 7-inch strands: 95%
  • 9-inch strands: 91%
  • 11-inch strands: 46%

It picked up over 90% to nine-inch hair but struggled with long eleven-inch strands, which isn’t surprising since it doesn’t have an anti-tangle system.

The Miele Triflex HX1 was worse, with nine-inch strands picking up less than the Dyson V12 Detect.

Miele Triflex hair wrap on carpet

  • 5-inch strands: 100%
  • 7-inch strands: 98%
  • 9-inch strands: 37%

You can see the hair wrapping on the brush. So consumers will need to remove the brush to dislodge it.

Another advantage of the V12 Detect is it has a torque screw tool, enabling it to vacuum long hair strands on upholstery.

Traditionally designed brush rolls will struggle to clean this much hair, but not this tool.

There’s nothing wrapped on the roller, even with this much hair.

Noise Comparison

ModelMiele Triflex HX1Dyson V12 Detect
Low77.2 dB70.1 dB
Auto/Mid82.8 dB72.5 dB
Max83.8 dB80.7 dB

The Miele Triflex HX1 is the noise option, exceeding 83 decibels in the max setting, a few more decibels higher than the V12 Detect, which is one of its more significant drawbacks, even with the lower airflow output.

It’s also noisier in the lower settings, so I don’t recommend using it late at night, especially inside apartment-type homes where your neighbors are nearby.


All cordless stick vacuum products need upkeep to maintain performance for years. And I’ll enumerate the components you need to clean or replace below.

  1. Primary brush roll: Cleaning it weekly to remove any hair or debris buildup on the roller or axles. This should be a straightforward task since the brush rolls are detachable.
  2. Dustbin: Empty it after every cleaning cycle to prevent dust mites from breeding.
  3. Filter: Clean it monthly using only water and dry it before reattaching it inside the dustbin. I’d recommend purchasing an extra filter to prevent any downtime.
  4. Battery: Avoid using the max setting for extended stretches to prevent it from overheating and shortening its lifespan.
  5. Attachments: Clean them using a (slightly) damp microfiber towel to remove any dust accumulation.

Which Option Offers Better Value?

The price disparity between the Dyson V12 Detect and Miele Triflex is closer than with the V15 Detect, so it shouldn’t be a significant deal breaker.

Each product has its distinct advantages. The V12 Detect offers better versatility and ergonomics since it has more tools and it’s lighter.

In contrast, the Miele Triflex HX1 has more capacity, and consumers can store it upright without a dock.

5 Reasons to Choose the Dyson V12 Detect

  1. More technology: The V12 Detect offers a more refined technological toolset than the basic Triflex. It has a laser slim roller, interactive LCD screen, and torque screw tool, helping consumers be more proficient at cleaning their homes.
  2. Longer run time: Despite using the same capacity (2500 mAh) lithium-ion battery, the V12 Detect runs further at over 63 minutes with the soft roller tool.
  3. Better at cleaning hair: It’s better at resisting hair tangles on both surfaces.
  4. Excellent at tracking dust: The laser slim roller is the best-in-class at tracking almost invisible dust.
  5. More tools: Consumers will get more attachments from the V12 Detect.

3 Reasons to Choose the Miele Triflex HX1

  1. Larger dustbin: Miele has a larger volume (0.5 vs. 0.35), so consumers can vacuum a larger space.
  2. Self-standing: One of the Triflex configuration options allows for vertical storage without a dock, which is a plus for convenience.
  3. Above-average on carpets: It was excellent at cleaning surface and embedded debris carpets.

The Verdict: Dyson V12 Offers Better Value

One reason I say the Dyson V12 Detect has better value is the price variance, which is negligible – depending on where you purchase it.

Consumers will get more from the Dyson V12 Detect – better technology, more tools, longer range, and better hard floor cleaning performance.

Miele is a good vacuum, but its limitations and premium price level keep me from recommending it.

The only reason why I’d recommend it is it has a larger dustbin, and it’s self-standing without a dock.

Otherwise, the V12 Detect is better in other aspects.
