Miele Triflex HX1 vs. Dyson V15 Detect

Miele Triflex HX1 vs. Dyson V15 Detect

Miele was known for its bagged (and corded) upright vacuums, but HX1’s release changed all that, and we’ll see how it fares against the Dyson V15 Detect.

Both are versatile options, but each has unique strengths, with the Miele HX1 having more configuration options but the V15 Detect having more tools out of the box.

I’ve spent many hours testing both models in various aspects, from vacuuming performance to run time (and everything in between), to see which option is better.

Introduction to the Miele Triflex HX1 and Dyson V15 Detect

While these products are categorized as cordless stick vacuums, their designs differ vastly.

The V15 Detect has used Dyson’s framework since it started manufacturing cordless vacuums – the dustbin, motor, trigger, and handle on top with the extension tube and interchangeable tools.

Miele’s design is more nuanced with two stick vacuum configurations – the dustbin frame on top or in the middle.

Each of these designs offers distinct advantages and disadvantages we’ll look at below.

More Configuration Options: Miele Triflex HX1

Miele Triflex upright configuration


  • Versatile configuration options
  • Above-average deep cleaning performance
  • Decent-sized dustbin (0.5 liters)
  • Self-standing, even without a dock
  • It will run for over 60 minutes


  • Not ergonomic in its handheld configuration
  • Expensive
  • Limited versatility with the bulky frame
  • Didn’t pass the fog test

For many years, Miele manufactured bagged upright and canister vacuums, but with the popularity of cordless vacuums, it has dipped its toes into this niche with the Triflex HX1.

The Triflex branding refers to the three configuration options.

First is the traditional stick vacuum configuration with the dustbin/motor frame on top.

Miele Triflex stick configuration

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

Another option is to attach the container to the middle section, giving it more balance and enabling self-standing storage.

Lastly is the handheld configuration, which is my least favorite because of its bulky and weight.

Miele Triflex handheld configuration

Cleaning performance is above average since it has decent airflow, but the lack of a soft roller attachment huts its efficiency on hard floors.

It got a good score, but it’s not something I’d recommend on this surface (only 77% average).

But it’s much better on carpets, getting an excellent 99.77% score on surface debris and 93.9% on embedded sand.

If there’s one reason to opt for this product, it’s its carpet cleaning performance and self-standing feature, but that’s it.

Better Technology: Dyson V15 Detect

Dyson V15 Detect


  • More technology than the Miele Triflex
  • Superb cleaning performance (on hard floors and carpets)
  • Almost-invisible dust will pop with the laser slim roller
  • Larger dustbin
  • Premium deep cleaning performance
  • Lengthy run time (over 84 minutes)
  • Excellent at cleaning hair (even long strands)


  • Extremely expensive
  • Top-heavy design

The Dyson V15 Detect is the opposite of the Miele Triflex HX1. Whereas Miele uses (mostly) analog controls, Dyson utilizes a lot of digital.

One feature Dyson introduced with the V15 Detect is the Piezo sensor readout behind the motor.

It shows a readout of the quantity of various debris sizes. But this isn’t the most helpful feature (in my opinion).

That distinction goes to the laser slim roller, flashing bright green light, revealing almost-invisible dust particles.

Dyson V15 green light expose dust particles

I’ve reviewed a bunch of LED-equipped stick vacuums, but none of those match the dust-popping illumination of this tool.

Dyson also upgraded the standard brush roll by adding combs and tweaked the bristle base to improve its anti-tangle properties.

Dyson V15 high torque nozzle

It retains the adjustable gates but with better hair-cleaning performance.

Another tool Dyson introduced, perhaps my favorite, is the Torque Screw Tool.

Dyson V15 torque screw brush out

Nothing seems to tangle on it, even (extremely) long hair strands.

Its tapered brush shape and indentations force hair towards a holding area inside the dustbin, making it the best handheld tool for cleaning hair.

The V15 Detect offers better cleaning performance on hard floors because it has a soft roller attachment, but the variance on carpets isn’t as significant.

The V15 is a better option for cleaning embedded debris because of its higher airflow.

Similarities of the Miele Triflex HX1 and Dyson V15 Detect

Next, we’ll look at the similarities between these versatile stick vacuums.

1. Versatility

Both products offer consumers different configuration options as a handheld and stick vacuum.

Miele offers more versatility in this aspect I discussed earlier and is better with its stick vacuum ergonomics in specific configurations.

But Dyson has better usability, especially in its handheld configuration because of the lighter body.

2. High-End Agitation (on Carpets)

Another similarity is the premium-level agitation, especially on surface debris on carpets.

These products have stiff bristles, but Dyson’s brush is thicker and can resist tangles better, whereas Miele’s brush is thinner.

There’s not much difference in cleaning surface debris on carpets, but the V15’s higher airflow and chunker brush enables it to pick up more embedded sand (100% vs. 93.9%).

Differences between the Miele Triflex HX1 and Dyson V15 Detect

Next, we’ll look at the meat of this article – the differences between these products.

1. Framework

Miele Triflex HX1 and Dyson V15 Detect framework

Miele and Dyson utilize different frames. Dyson uses a horizontally aligned dustbin (introduced in the V10) with a hygienic system.

Dyson V15 hygienic system

Miele uses the same horizontally aligned dustbin, but its handle position is in a different location.

The Triflex HX1 has no hygienic system, but the broad opening makes it easy to empty.

2. Dustbin Design

Aside from the horizontal alignment, many variances exist with the Dyson V15 Detect and MIele Triflex HX1.

The first is capacity – the V15 Detect has a larger volume at 0.77 liters, more than 50% more than the Triflex’s capacity of 0.5 liters.

There’s also a variance with emptying the dustbin contents.

Miele’s design allows consumers to attach the dustbin near the base. It has a twist-to-open mechanism to detach the container from the frame.

Emptying the V15’s dustbin is more straightforward, with fewer steps.

Remove the extension tube or attachment, point the container to the trash bin, then push the red lever underneath the container.

3. Primary Nozzle

Another difference is the brush roll design. The V15 Detect comes with two – a soft roller and a standard brush roll for cleaning hard floors and carpets, respectively.

Dyson V15 soft roller attachment

The Miele Triflex HX1 only has a standard brush roll with a low clearance, so I don’t recommend it for vacuuming hard surfaces.

4. Tools

The V15 Detect comes with more tools, one of Dyson’s better offerings in this category.

Dyson V15 tools

The Miele Triflex HX1 doesn’t have as much, with only attachments.

Miele Triflex handheld tools

It only has three tools for handheld use, but the bulky frame makes it challenging to use in this configuration.

5. Power Switch

Lastly, for this section is the power switch. Dyson utilizes the trigger for the V15 Detect, the same one found in most of its models.

Dyson V15 trigger

It’s designed to maximize run time since power is only used on demand, whereas the Miele Triflex HX1 uses a (more traditional) slide switch.

Ergonomic Comparison

Dyson wins this category because it has better steering with the ball system, especially on hard floors where it’s much smoother.

Miele steers decently, but it lacks the sharp turning radius of the V15 Detect, regardless of surface.

Another advantage of the V15 Detect is that it has better handheld ergonomics.

Not that it’s lighter, but its handle position provides better conform for extended use.

  • Miele Triflex HX1: 4 pounds 10.5 ounces
  • Dyson V15 Detect: 4 pounds 8.4 ounces

The Triflex HX1’s bulky frame hinders its ability to reach underneath furniture.

Even with the traditional stick vacuum confirmation, the V15 is still better because it has a slimmer profile and an optional under-appliance tool for reaching deep underneath furniture.

Dyson V12 under attachment

The photo above shows the V12 under-appliance attachment, but the V15 has the same tool.

Interface Comparison

The Dyson V15 Detect and Miele Triflex HX1 have various interfaces.

Dyson is more high-tech with the Piezo readout and real-time run time status, while Miele has a simpler interface with the slide switch and LED battery indicator.

Therefore, the Dyson V15 Detect wins in this category because of the practicality of the LCD screen.

Run Time Comparison

Dyson V15 Detect
Hard Floor84:19 mins41:30 mins.N/A
Carpet56:58 mins17:23 mins11:02 mins
Miele Triflex HX1
Cleaning Nozzle30:06 mins21:03 mins16: 18 mins
Non-powered tools62:43 mins24:28 mins17:33 mins

The Dyson V15 Detect runs much longer, even with the cleaning nozzle (84 vs. 30 mins) – more than doubling the range.

Also, there’s a considerable gap between Miele’s run time with the non-powered tools and Dyson’s range with the cleaning head (84 vs. 62 mins).

The V15 Detect is better because it has a larger capacity battery (3600 vs. 2500 mAh) that’s more energy dense.

Also, there’s better availability, and some V15 Detect variants come with two batteries and chargers.

Airflow Comparison

I use an anemometer to measure airflow to check power, which I think is a better gauge than pure suction in predicting cleaning performance.

Miele Triflex HX1
Wand34.55 CFM48.72 CFM54.88 CFM
Cleaning Head35.88 CFM41.91 CFM45.75 CFM
Dyson V15 Detect
Wand34.55 CFM42.38 CFM73 CFM
Cleaning Head29.98 CFM36.32 CFM69.19 CFM

Surprisingly, the Miele Triflex HX1 has more airflow at the cleaning nozzle than the V15 Detect, but the latter (not a surprise) was better in the max setting.

Another surprising result is the higher output in the medium setting.

Nonetheless, even in the middle setting, the V15 is better at deep cleaning.

The V15 Detect has as much as 40% more at the highest setting, which gives it a massive advantage in deep cleaning carpets.

Cleaning Comparison

ModelDyson V15 DetectMiele Triflex HX1
Hard Floors (Surface Test)99.85%77.75%
Sand on Hard Floor99.8%100%
Carpet (Surface Test)100%99.77%
Deep Cleaning100%93.9%

Dyson’s higher airflow is confirmed in the cleaning experiments, where it got higher averages on both surfaces.

It’s much better on hard floors because of the soft roller attachment. And on carpets with higher airflow and better brush roll design.

Miele was decent but only excels on carpeted surfaces since it only has a standard brush roll.

Which Option is Better on Hard Floors?

No doubt, it’s the Dyson V15 Detect, as confirmed in the cleaning experiments.

Miele’s lack of a soft roller attachment hurts its performance on this surface.

It struggles greatly with large debris piles wince the cleaning nozzle doesn’t have much clearance.

Surprisingly, the Triflex HX1 was better at vacuuming sand (100% vs. 99.8%), but the difference is tiny.

However, the Dyson V15 Detect was much better with the other surface experiments because it has a laser slim roller.

Hair Wrap [on Hard Floors]

Another benefit of the V15’s high airflow is its performance on hard floors. Even without an active-tangle system, it picked up a high percentage even with long hair strands.

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

It was perfect between five and eleven inches, picking up 100% on these experiments.

And even with 12-inch strands, it (still) got an 80.6% score.

However, one weak spot for the laser slim roller is the gap at the edge where hair will wrap around, and something to check during maintenance tasks.

Miele doesn’t have as much airflow and didn’t do as well with the narrow brush roll and the lack of combs.

Miele Triflex hair wrap on hard floors

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

There’s visible hair wrapping on the brush even in the seven and nine-inch experiments, so it’s not something I’d recommend for cleaning hair.

Another reason the Dyson V15 is better in this category is the Torque Screw Tool, which is excellent at cleaning long hair strands.

Edge Cleaning Comparison

Both options can efficiently clean the edges, needing only a few passes for the task.

Here’s a before and after shot for the Dyson V15 Detect.

There’s not much variance with the eye test as both got (nearly) everything out of this area.

Which Option is Better on Carpets?

The cleaning experiments on carpets were much closer for the Miele Triflex HX1 and Dyson V15 Detect, with Miele picking up in the high 99s and the V15 Detect getting a perfect score.

Dyson’s brush roll is better designed with the chunkier brush roll that agitates better than Miele’s thinner brush.

And you could see this variance in the deep cleaning experiment where the V15 Detect picked up 100% at the middle setting, and the Triflex only got 93.9%.

Hair Wrap [on Carpets]

Again, Dyson’s high airflow and brush roll enhancements give it a significant advantage in cleaning hair on this surface.

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%

It got 100% with shorter five to nine-inch strands and (still) excellent 99% and 98% with eleven and twelve-inch strands, respectively.

These are much better results than the V11 and Outsize – the latter struggling with longer strands.

Miele was (surprisingly) better at cleaning hair on carpets than on hard floors.

Miele Triflex hair wrap on carpet

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

It struggled with long strands, only getting 37%, and the eye test confirms it as a huge chunk wrapping on the brush.

Deep Cleaning Comparison

Again, the Dyson V15 Detect is better at deep cleaning carpets because of its high-end agitation and premium airflow.

It got an average of 100% in deep cleaning experiments, even in the auto setting, whereas the Miele Triflex HX1 only picked up 93.9% (in the max setting).

Noise Comparison

ModelMiele Triflex HX1Dyson V15 Detect
Low77.2 dB70.3 dB
Auto/Mid82.8 dB72.5 dB
Max83.8 dB80.8 dB

Despite the lower airflow and suction, the Miele Triflex HX1 is the noisier option, exceeding 80 decibels.

The Dyson V15 Detect is noisy but much quieter in the low and auto settings, so it’s the less noisy option.


These products need some TLC to function efficiently for years, and if you’re spending a few hundred dollars for something, you’ll want it to last as long as possible.

I’ll enumerate the list of components to clean or replace.

  1. Primary brush roll: Clean the roller weekly to remove accumulated dirt and hair on the axles.
  2. Dustbin: Empty it after every cleaning cycle to prevent dust mites from breeding.
  3. Filter: Wash the filter every month. I’d recommend purchasing an extra to minimize downtime waiting for it to dry.
  4. Battery: Avoid using it in the max setting for extended stretches to prevent it from overheating.

Which Option Offers Better Value?

Despite the price discrepancy, I think the Dyson V15 Detect offers better value because of its versatility and cleaning performance.

The Triflex HX1, in theory, is usable as a handheld, but it’s not comfortable to use because of its bulk.

Plus, the lack of a soft roller hampers its performance on hard floors, limiting use to only carpets.

3 Reasons to Choose the Miele Triflex HX1

  1. Cheaper option: The Triflex HX1 is a few hundred dollars cheaper than the V15 Detect.
  2. Above-average carpet cleaning performance: It isn’t far off with cleaning surface debris on carpets.
  3. Self-standing: It has one configuration where consumers can store it vertically without a third-party dock.

5 Reasons to Choose the Dyson V15 Detect

  1. Longer run time: The V15 Detect more than doubles than Triflex HX1 run time with the cleaning nozzle (84 vs. 30 mins).
  2. Better at cleaning hair: It’s better at resisting tangles, even with long hair strands above nine inches.
  3. More tools: Consumers will get more tools out of the box.
  4. Better handheld ergonomics: The V15’s handle position and tool variety make it a better handheld option for above-floor cleaning.
  5. Tracks dust: This model is (probably) the best at illuminating almost-invisible dust.

The Verdict: Dyson is Still the Better Option

Even if the Miele Triflex HX1 is cheaper, the Dyson V15 Detect offers more value for your dollar.

It has more tools, technology, and better cleaning performance on both surfaces.

The only reason I’d recommend the Triflex HX1 is the price, above-average carpet cleaning performance, and self-standing feature, but that’s it.

Not having a soft roller attachment hinders its performance on hard floors since it snowplows large debris piles.

Also, the bulky frame limits its reach underneath furniture. Its default configuration almost has an upright vacuum feel, which is cumbersome to steer and heavy.
