Miele Triflex HX1 Review: Check What Experts Say!

You are currently viewing Miele Triflex HX1 Review: Check What Experts Say!

This review will focus on the Miele Triflex HX1 model, Miele’s first and actually the only cordless stick vacuum to the deepest point.

It looks very much like a stick vacuum at first glance. However, there are two configurations that allow for more versatility and give consumers more options.

It can be used as a stick vacuum, having the motor on the top. However, you can also use it upright with the motor located near to its base (which proves to be very useful).

This vacuum has been subject to numerous tests, and we’ll share the results in this review.

Summary of Miele Triflex HX 1

If you choose the base version, the Miele Triflex carpet cleaner is a great alternative. The price is right – it’s not as expensive as the Dyson V11 but has the same cleaning performance.

Its upright design is our favorite because it’s the most comfortable to use. There are issues with noise, filtration, and handheld usability. This is an excellent choice if you are looking for a cordless carpet cleaner that can stand alone.

Triflex HX1 is Miele’s first cordless stick vacuum. It’s a bold attempt to break the mold. While other brands only offer one configuration, the Triflex HX1 has three.

The carpet cleaning results were excellent, but the absence of a soft-rolling nozzle reduces effectiveness on hard surfaces (only a bit, and you can truly neglect that). The stick vacuum’s ergonomics are good, especially when used in an upright position, and also, the steering is cool and doesn’t lack responsiveness at all. It’s easy to maneuver in tight spaces, no matter if it has a bulky frame.


  • Airflow and suction are above-average
  • More than 90% of deep cleaning tests were performed in the middle setting.
  • It’s easy to switch between different power settings with your fingertip controls
  • Vacuum hard floors and carpets thoroughly
  • This upright position doesn’t strain your wrists and arm muscles.
  • Battery detachable
  • It is easy to empty the container with the twist-to-open system


  • Loud at top speeed.
  • It is not very comfortable to use handheld

Let’s Introduce the Miele Triflex X1

Miele is well-known for its bagged canister vacuums. Although we were surprised to see this vacuum, there is no reason it should not be.

Miele Triflex HX1 sticks vacuums with a nice unique design. It is not like other brands that place the motor close to the handle.

Miele also offers two options for customers. Stick vacuum mode is another option, with the motor and dustbin located near its handle.

The last one is handheld configuration. The upright configuration is our favorite because it provides the perfect ergonomics while cleaning floors. It’s much easier to move because the weight bulk is close to the base.

We don’t think you would use the stick mode if you have to switch to a handheld. Honestly, the handle placement is great for cleaning floors, but it’s not ideal for handheld use since you have to carry the bulk. While it’s easy to clean flat surfaces, it can be problematic for vertical cleaning.

However, if you want to use it only for a while, then the weight won’t hurt you.

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

Triflex also offers three additional options (at most on Amazon). The base model, the HX1, is what I have. These three tools are included in the package.

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

The HX1 Cat & Dog is next, which is for pet owners. This model has the same toolset and features as the HX1 Base, but it comes with a handheld electro brush. This is Miele’s mini turbo brush.

The premium option – HX1 Pro, comes with the LED-equipped Multifloor XXL BrilliantLight nozzle. It also includes an extra battery that increases its run time from 60 mins to 120 mins.

Design and capacity of dustbins

The dirt volume of the Triflex is only 0.5 liters, even with its upright configuration.

Although it won’t retain much dirt, we loved the upright position. This is another reason we preferred to use it in this configuration in our testing.

There are many layers of filtration. The outer mesh layer is the most important. It contains two filters, a primary cylindrical-shaped filter, and a secondary circular-shaped filter. A smaller middle filter is also included. These filters are washable and can effortlessly used for a lifetime, according to Miele. They also have 99.999% filtration.

Cleaning nozzle

The Triflex nozzle is about 11 inches in width, which is greater than an inch more than the other brands. The nozzle’s width permits it to remove more debris as compared to the nozzle’s narrower size However, this also allows it to be simpler to carry.

It is a protruding swivel device however it can be used in small spaces. It also hinders the Triflex model from cleaning under furniture that has very little clearance. Brush rolls are a standard one and Miele states that it’s multi-floor. However, it’s not the most effective.

Brush rolls can be thin, with stiff bristles. This is the reason it doesn’t perform effectively with hair with long strands.

The nozzle of the Miele nozzle is not like the Dyson torque drive attachments, which comes with two gates. Still, it picked up much on the pile of Quaker oatmeal.


Miele Triflex Miele Triflex includes a removable battery that is quickly replaced, and has a longer run duration. This model HX1 Pro can be purchased to include two batteries included in the box.

Ergonomics and Usability

Miele Triflex HX1

Its upright configuration is actually the most comfy and ergonomic for the Triflex HX1. The handle position of the Triflex HX1 is perfect for upright use with the motor at its lower end. The combination of these factors reduces the weight on the top.

It can also be stored vertically without the need for a dock, which is another reason our experts loved its upright design. Also, it will not stand by itself if it is used in the stick vacuum configuration.

It can be used for two purposes. If you have to clean under furniture, the primary reason is why it’s used as a stick vacuum. The dustbin can be moved towards the handle to remove a major roadblock, allowing it to move further.

The second reason is that you will rely on it extensively as a handheld since switching from stick to handheld is easier in this form.

How Long Does the Triflex HX1 Last?

Miele uses a VART Lithium battery with a rating of 2500 milliamps and a claimed time of 60 mins. It comes with a non-powered tool.

This vacuum cleaner took only 29 mins to clean the carpet with the main nozzle when it was in the lowest setting. It cleans carpet as deep in the middle setting as in the maximum setting. This is a good thing. The average 21-minute time is better than average.

What Power Does the Miele Triflex HX1 Model Have

Airflow and suction were two aspects I was eager to test with the Triflex. It was good. We tested it with a water lift gauge and an anemometer.

Let’s first look at the results of airflow.

Area Tested Low Mid Max
Cleaning head 35.62 CFM 41.88 CFM 45.78 CFM
Non-powered tools 34.47 CFM 48.68 CFM 54.91 CFM

It’s good  in the low and middle setting. It truly tapers off at the max.

Battery Low Mid Max
Cleaning head 30:03 mins 20:45 mins. 16: 03 mins
Non-powered tools 58:41 mins 24:13 mins 17:24 mins

The results of cleaning verify this. The Triflex has almost identical results for deep cleaning both at the maximum and mid settings. Tests of suction were great and uniform for all configurations.

  • Y-gauge (sealed): 21 CFM
  • Y-gauge (unsealed): 18 CFM
  • Water lift (direct): 21 CFM

Since it contains the fewest variables, the unsealed result is our favorite. It also represents the vacuum’s working suction. It is only beyond the Torque Drive and Outsize with an unsealed test. We believe this is a good companion for a stick vacuum.

Cleaning Results

The Miele Triflex HX1 was tested with various debris, including quinoa, pet litter, coffee grounds, quaker oatmeal, hair, and coffee grounds.

Let’s first look at the overall results.

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

Its average performance in vacuuming using the quaker oatmeal was the reason it did not exceed 95, however 92.7 is also a great score. It could have had more points if it didn’t. It performed so well on hard flooring that we were pleasantly surprised. This is a rare achievement for vacuums that do not have a soft-roller.

Results from hard floors

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

It did well with the rest of the experiments, picking out above 99% despite its struggles with quaker oatmeal. It passed without any debris, which is a sign that it has good airflow and seal.

Hair wrap test on hard floors

Let’s now see how the Miele Triflex performed in resisting hair tangles. Here are our results of our tests on hair strands ranging from five to nine inches.

  • 5-inch strands: 97%
  • 7-inch strands: 85%
  • 9-inch strands: 55%

It was able to manage strands up to seven inches in length, but it struggled with long hair over nine inches. It can’t handle long hair because of its narrow roller. Plus, it doesn’t have any combs for untangling them. This would be too difficult to use for long strands. However, it could work for shorter ones.

Sand on hard floors results

It also picked up sand perfectly, which is one of the most difficult things to clean on this surface. It was able to pick up an average of 99.9%, which is much better than stick vacuums that use a soft-roll attachment.

Edge cleaning

Miele Triflex HX1 (3)

The Miele Triflex cleaned this area well, despite not having a soft-rolling tool. The Miele Triflex was very efficient and took only a few passes to enjoy the results you see.

Crevice pick-up test

Another experiment I conducted was a crevice pick-up test. We set out to scatter debris in a quarter-inch crevice. This proves that the Miele TriflexHX1 has an above-average airflow.

Results with low pile

  • Quaker oats are 99.98%
  • Coffee grounds: 98.51%
  • Pet litter: 100%
  • Quinoa: 99.63%

The Miele Triflex HX1 is a great choice for carpet cleaning due to its superior airflow and brush roll design. It’s easy to notice the difference with the excellent scores all around.

Although the coffee grounds experiment might suggest otherwise, the eye test revealed that it picked up almost all of the coffee grounds and left almost no visible trace particles.

Carpet with a mid pile

  • Quaker oats 99.84%
  • Coffee grounds: 99.98%
  • Pet litter: 100%
  • Quinoa: 100%

It cleaned the mid-pile carpet better, at least in our experiments. The passes were clean and there was no visible debris. You can also check out Miele C1 vs C2 who perform well.

Deep cleaning results

At the mid-level setting, the Miele Triflex managed to pick up embedded sand (94.15%), which was a surprise to us. It actually had a higher average at its middle setting than it did at its max setting (93.65%), which was a surprise to us but still, it is decent for this purpose.

It scored an average of 93.9% on the four tests it passed.

Carpet hair wrap test

We also tested the Miele Triflex HX1’s resistance to tangles on the carpet. Surprisingly, the Miele Triflex HX1 worked well with shorter strands of five to seven inches but not with nine inches.

  • 5-inch strands: 99.95%
  • 7-inch strands: 98.2%
  • 9-inch strands: 39.4%

How Loud Is the Miele Triflex X1?

The Miele Triflex has a problem with high noise levels, especially when the main nozzle is attached.

Zone Low Mid Max
Cleaning head 72.1 dB 81.3 dB 82.1 dB
Non-powered tools 69.8 dB 77.3 dB 78.4 dB

The nozzle was at its maximum setting and the middle setting, exceeding eighty decibels. This is the highest level we have ever tested for stick vacuums. Using suction-only tools, these figures drop too much more manageable levels below 80 decibels.

Parts availability

Parts availability won’t be an issue for Miele brands, except for the filter and battery. Triflex isn’t as well-known as Dyson, so it’s unlikely that third-party manufacturers will see them.

Amazon Store sells filters and batteries. You can even get them at the Miele website.

Is the Miele Triflex a Great Value?

Miele Triflex HX1 (2)

It depends on which variant you opt. The HX1 base model is our favorite. It is priced at an acceptable price for the performance it offers. Although the Cat & Dog does offer more, we think it is slightly expensive.

Here are some reasons to choose this German-made stick vacuum.

Four Reasons to Buy the Miele Triflex X1

  1. It’s easy to empty the dustbin: We love the twist-to-open mechanism during the testing. It is easy to use, and you don’t have to use your finger to touch the dirt.
  2. It cleans deep: The product does a great job cleaning embedded sand from the middle setting.
  3. High carpet cleaning performance: Triflex HX1 mode comes with a nice wide nozzle with strong and stiff bristles that makes it easy to clean.
  4. Self-standing feature: Our favorite configuration is the upright one, which can stand on its feet.

The Verdict: The Base Model Is a Great Value for Carpet


The Miele Triflex HX1 is amazing at cleaning floors. It was able to clean other types of debris, such as coffee grounds and sand, with no problems.

Its efficiency is affected by the absence of a soft-roll attachment, but it still picks off debris. It shines on the carpet with its stiff bristles and above-average suction.

With its excellent floor cleaning abilities, the base model is our favorite. The Cat & Dog model is a better value. Its handheld ergonomics are less than perfect. A Dyson V11 Torque Drive is about the same price. It offers superior cleaning performance and a larger dustbin.
