Miele Triflex HX1 Review

Miele Triflex HX1 Review

In this review, we’ll look at the Triflex HX1, Miele’s first and only cordless stick vacuum.

At first glance, it looks like a traditional stick vacuum, but it has two other configurations, which add to its versatility and give consumers more options.

Aside from using it as a traditional stick vacuum with the motor on top, it can be used in an upright configuration with the motor closer (my favorite) to the base and handheld.

I’ve put this vacuum through many tests and I’ll reveal the results in this review.

Excellent on Carpet, Average on Hard Floors
  • Ergonomics - 93%
  • Surface Cleaning - 92.41%
  • Deep Cleaning - 93.9%
  • Quality - 95%
  • Design - 94%
  • Value - 94%


The Miele Triflex is an excellent, cheaper alternative for cleaning carpets IF you opt for the base variant, which is the best, in my opinion. Its price is in a sweet spot – not as expensive as a Dyson V11, but it offers nearly the same vacuuming performance. I enjoy its upright configuration since it’s the most ergonomically pleasing. But there are some issues with the noise, not-so-responsive steering, filtration, and handheld usability. If you’re looking for a cord-free carpet-cleaning vacuum that can stand independently, this is a good option.


  • Vacuums hard floors and carpets well
  • Picked up over 90% in deep cleaning tests in the middle setting
  • The upright configuration doesn’t strain your arm and wrist
  • Above-average suction and airflow
  • The twist-to-open mechanism makes it easy to empty
  • Detachable battery
  • Fingertip controls make it easy to toggle between the different power settings


  • Subpar run time with the nozzle attached (only 30 mins)
  • Not very comfortable to use as a handheld
  • Lacks efficiency on hard floors
  • Very noisy
  • Expensive (especially premium models)

Introduction to the Miele Triflex HX1

Miele is a well-known brand for people familiar with vacuum cleaners, particularly bagged canister vacuums.

So when I saw this product, I was a bit surprised, but with the growing interest in cordless vacuums, it shouldn’t come as such.

The Miele Triflex HX1 has a unique design, not common in full-sized stick vacuums.

Unlike other brands with the motor near the handle, it is close to the base.

This configuration is similar to the Lupe Pure and Shark ION P50.

However, Miele offers two other options for consumers.

The next option is the stick vacuum mode, where the dustbin and motor are near the handle.

And lastly is the handheld configuration.

My favorite of the three is the upright setup since it offers the best ergonomics cleaning floors.

With the bulk of the weight close to the base, it’s easier to move around.

The only reason you’d use the stick configuration (I think) is you’ll need to transition to a handheld.

While the handle placement is ideal for cleaning floors, it isn’t in handheld mode since you’ll have to carry most of the weight.

It’s not an issue cleaning flat surfaces, but it can be for tackling vertical spaces.

Different Triflex Options: HX1 vs. HX1 Pro vs. HX1 Cat & Dog

There are three other Triflex options (at least on Amazon).

The model I have is the base variant, the HX1. It comes with these three above-the-floor tools.

  1. Upholstery tool
  2. Crevice tool
  3. Brush tool

Next is the HX1 Cat & Dog, which is designed for pet owners.

It has the same toolset as the base HX1 but with the handheld electrobrush, Miele’s version of a mini turbo brush.

The HX1 Pro is the premium option with the LED-equipped nozzle, which Miele calls the “Multifloor XXL BrilliantLight.”

It also comes with an extra battery that doubles the run time from 60 minutes (claimed) to 120 minutes.

Dustbin design and capacity

Even with the upright configuration, the Triflex’s dirt volume is below average at only 0.5 liters.

It won’t hold much dirt, but I like its placement as an upright – another reason why I prefer using it in this configuration.

There are several layers of filtration, starting with this outer mesh layer.

Inside it are two filters – a primary cylindrical shaped filter.

And a smaller middle filter inside.

Miele says these are lifetime filters and washable with 99.999% filtration.

However, it did not pass the fog test, and there were visible leaks at the exhaust.

Cleaning nozzle

Staying true to its roots, the Triflex utilizes a wide nozzle at around eleven inches – more than an inch broader than other brands.

This board width enables it to vacuum more debris than a narrower head but at the expense of portability.

It won’t do well in tight spaces because of it and this protruding swivel mechanism.

Also, it hinders the Triflex from going under shallow clearance furniture.

It only has a  traditional brush roll, and while Miele says it’s “multi-floor,” I wouldn’t recommend it on hard floors.

The brush roll is on the slim side with stiff bristles, which is why it didn’t do well with longer hair strands (more on that later).

Also, it has a low clearance inlet, hampering its performance on hard floors.

Unlike the Dyson torque drive attachments that have two gates, Miele’s nozzle does not.

I tried it on this pile of quaker oats, and it didn’t pick up much.

Fortunately, it did better with other debris, but I’m pointing out that there are limitations.


Miele Triflex battery

The Miele Triflex has a detachable battery, making it easy to replace and extend run time if you purchase.

You can get two batteries out of the box by purchasing the HX1 Pro, plus an extra charger.

Ergonomics and Usability

The Triflex HX1’s upright configuration is the most ergonomic mode. Its handle position is ideal for upright use, with the motor at the lower end.

This combination of factors lightens up the load on top.

Another reason why I like its upright configuration is you can store it vertically without a dock.

However, using it in its stick vacuum configuration will increase the handle weight, and it won’t stand independently.

You’ll use it as a stick vacuum for only two reasons.

The first reason is if you need to clean under furniture. Relocating the dustbin towards the handle removes a significant roadblock, enabling it to go further.

And the second reason is if you’ll rely on it as a handheld extensively, since transitioning from stick to handheld is more straightforward in this form.

How long with the Miele Triflex HX1 run?

Miele utilizes a VART Li-ion battery rated at 2500 milliamps with a claimed run time of 60 minutes.

But please note that it is with the non-powered tool attached.

With the main nozzle, it only lasted 30 minutes in the lowest setting.

Cleaning head30:06 mins21:03 mins.16: 18 mins
Non-powered tools62:43 mins24:28 mins17:33 mins.

The good news is it deep cleans carpet as well in the middle setting as it does in the max setting, so the 21-minute figure is above-average.

How much power does the Miele Triflex HX1 have?

One aspect I was looking forward to testing with the Triflex is suction and airflow.

I used an anemometer, water lift gauge, and Y-gauge to assess how much it has, and it was decent.

First, let’s look at the airflow results.

Area TestedLowMidMax
Cleaning head35.88 CFM41.91 CFM45.75 CFM
Extension tube34.55 CFM48.72 CFM54.88 CFM

It’s above average in the low and middle settings but tapers off in the max.

This is confirmed in the cleaning results (up next), where the Triflex had nearly identical deep cleaning results in the mid and max settings.

Suction tests were also above-average and even across the board.

  • Water lift (direct): 22 foot pounds
  • Y-gauge (unsealed): 19 foot pounds
  • Y-gauge (sealed): 22 foot pounds

In my opinion, the unsealed result is the most accurate since it has the least number of variables and represents the working suction of a vacuum.

It’s only behind the V11 Torque Drive and Outsize with the unsealed test, which I think is good company for a stick vacuum.

Cleaning Results

I tested the Miele Triflex HX1 with various debris like quaker oats, quinoa, pet litter, sand, coffee grounds, and hair.

First, let’s look at the overall results.

  • Overall: 92.78%
  • Hard floor: 77.75%
  • Sand on hard floor: 100%
  • Carpet: 99.77%
  • Deep cleaning: 93.9%

The overall score is skewed by its poor performance vacuuming quaker oats. Otherwise, it would have been a higher average.

I was pleasantly surprised at how much it picked up on hard floors, which is a rarity for stick vacuums without a soft roller.

Hard floor results

Miele Triflex hard floor results

  • Quaker oats: 12%
  • Coffee grounds: 99%
  • Quinoa: 100%
  • Pet litter: 100%

Despite its quaker oats struggles, it did well with the other experiments, picking up above 99%.

Passes were clean, which shows it has a good seal and airflow to pick up debris.

Sand on hard floor result

Another surprise is how well it picked up sand, one of the most challenging stuff to clean on this surface.

It picked up an average of 100%, which is better than other stick vacuums with a soft roller attachment (Dyson V15 Detect, Shark Vertex Cordless, Tineco A11).

Hair wrap test on hard floors

Next, let’s look at how well the Miele Triflex did at resisting hair tangles. 

I tested it on hair strands between five and nine inches, and here are the results.

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

It did well with five and seven-inch strands but struggled with nine-inch long hair.

The narrow roller is a factor why it couldn’t resist long strands, plus it does not have any combs to untangle them.

I would not recommend this for cleaning long strands, but it would suffice for shorter strands.

Edge cleaning

Despite not having a soft roller tool, the Miele Triflex did well cleaning this area, as you’ll see in the before and after photo below.

It was efficient, needing only a few passes to achieve the result you see above.

Crevice pick up test

Another experiment I did was a crevice pick-up test, where I scattered debris on this quarter-inch crevice.

The result above proves the above-average airflow that the Miele Triflex HX1 possesses.

Low pile results

Miele Triflex low pile results

  • Quaker oats: 100%
  • Coffee grounds: 98.6%
  • Quinoa: 99.8%
  • Pet litter: 100%

Cleaning carpet is where the Miele Triflex HX1 excels with its above-average airflow and brush roll design.

You can see it at play with the high scores across the board.

The coffee grounds experiment may say otherwise, but the eye test reveals it picked up most of it and didn’t leave visible trace particles.

Mid pile carpet

Miele Triflex mid pile results

  • Quaker oats: 99.8%
  • Coffee grounds: 100%
  • Quinoa: 100%
  • Pet litter: 100%

It did better cleaning mid-pile carpet, at least for my experiments, with close to a 100% average.

IIn the before and after shots above, you can see, you can see that the passes were clean, and there wasn’t any visible debris left.

Deep cleaning results

One surprise for me with the Miele Triflex is how well it picked up embedded sand in the middle setting (94.15%).

It actually got a higher average at the middle setting versus the max setting (92.65%), which is a head-scratcher for me, but regardless, it’s decent for this purpose.

Overall, it picked up an average of 93.9% in the four tests I did.

I also tested how well the Miele Triflex HX1 will resist tangles on carpet.

Surprisingly, it was better with shorter five and seven-inch strands but struggled with nine-inch hair.

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

How noisy is the Miele Triflex HX1?

One issue with the Miele Triflex is the high noise levels, particularly with the main nozzle attached.

Area testedLowMidMax
Cleaning head77.2 dB82.8 dB83.8 dB
Non-powered tools71.2 dB77.8 dB78.9 dB

It breached eighty decibels in the middle and max setting with the nozzle, one of the highest I’ve tested for stick vacuums.

But with suction-only tools, those figures go down considerably to more bearable levels below 80 decibels.

Availability of parts

Being a Miele brand, there won’t’ be an issue with parts availability, at least for stuff like the filter or battery.

However, don’t expect third-party manufacturers to see Triflex components since it isn’t as popular as a Dyson.

You can purchase filters and batteries from Amazon or the Miele website.

Does the Miele Triflex offer excellent value?

It depends on the variant you select. The base model HX1 is the best value option for me.

The price is at a sweet spot for the performance it brings to the table. You could argue that the Cat & Dog offers more, but it’s slightly overpriced, in my opinion.

To help you decide, I’ve come up with some reasons why you should go with this German-made stick vacuum.

4 Reasons to Purchase the Miele Triflex HX1

  1. Excellent carpet cleaning performance: The Triflex HX1 is built to clean this surface well thanks to the wide nozzle and stiff bristles.
  2. Deep cleans well: One surprise doing the tests is how well this product cleans embedded sand in the middle setting.
  3. Self-standing feature: My favorite configuration is the upright mode, where it can stand on its own.
  4. Easy to empty dustbin: I like the twist to open mechanism for emptying debris. It’s easy to use, and there’s no need to touch the dirt with your fingers.

The Verdict: Base Model is Excellent Value on Carpet

I’m pleasantly surprised with how well the Miele Triflex HX1 cleaned floors.

Aside from its struggles with quaker oats, it did well with other types of debris like coffee grounds, sand, and quinoa.

The lack of a soft roller attachment hurts its efficiency, but it still picks up debris.

On carpet is where it shines with stiff bristles, above-average suction, and a good seal.

The base variant is the best value, in my opinion, with its floor cleaning performance.

But I wouldn’t spend extra for the Cat & Dog model because its handheld ergonomics is less than ideal.

You could get a Dyson V11 Torque Drive for roughly the same price, which offers better overall cleaning performance and a larger dustbin.
