With its versatile design and dual batteries, the Miele Triflex HX1 Pro is an attractive cordless vacuum. But is it worth the high price tag? Read our in-depth review to find out.

Miele is known for their cylinder vacuums, but the HX1 series is their first attempt at a bagless cordless model. It’s a powerful stick vacuum with a 3-in-1 design, HEPA AirClean filter, and headlights. Miele has also included three power levels and a pivoting floorhead.

There are several versions of the HX1, including the “basic” version and the Cat & Dog. Unlike other versions, the HX1 Pro has two batteries for an extended run-time. It also comes with a battery charging cradle and Miele’s Electrobrush floorhead – along with an eye-watering price.

How does the Miele compare with other cordless vacuums though? Is the Pro version of the HX1 the best option? And can it justify the price? Read our Miele Triflex HX1 Pro review to find out!

Overview of the Miele TriFlex HX1 Pro’s Features

  • Power unit can be moved into three configurations (stick, upright, and handheld)
  • 0.5 litre dust capacity
  • Powerful suction that rivals other premium cordless vacuums
  • Two swappable lithium-ion batteries for a 120 minute maximum run-time (on lowest suction setting)
  • HEPA AirClean filter to capture allergens and other small particles
  • Electrobrush floorhead with BrilliantLight to illuminate dirt
  • Several non-motorised accessories

Miele Triflex HX1 Pro Appearance & Design

Split image of the Miele Triflex HX1 Pro

The Miele Triflex HX1 Pro is a stylish vacuum cleaner with a sleek, modern design. While it lacks some of the most advanced features of models like the Dyson V11, it’s a durable vacuum that’s powerful and easy to use.

When cleaning floors, the Miele’s pivoting floorhead makes the vacuum easy to navigate around the home. There’s also an automatic floor detection system (more on that later) and a simple sliding switch to move between the three power modes. You don’t need to hold down a trigger when cleaning either, which will be a relief to anyone who finds Dyson’s trigger system uncomfortable to use.

There are some downsides to the HX1’s design though. It’s not a heavy vacuum in comparison to corded uprights, but at 3.6kg it’s certainly above average for a cordless. It also only has a 0.5 litre dust capacity, so you’ll need to empty it regularly.

What Exactly is a “3-in-1” Design?

One of the key features of the HX1 series is the 3-in-1 design. Nearly all cordless stick vacuums have a handheld option, but you can move the power unit of the HX1 into three different positions. So, whether you need to maximise reach, want to make the vacuum more comfortable to hold when cleaning floors, or need to clean tight locations, there’s a configuration option for almost any cleaning task.

Here’s an overview of the three HX1 configurations:

  1. Stick mode with the power unit at the top of the tube (Reach Mode). This is the most manoeuvrable option and is great for cleaning under furniture, as the bulky floorhead isn’t in the way. It’s also a useful mode for vacuuming cobwebs on ceilings. The downside is that the power unit is quite tiring to hold in this position, as you need to support most of the weight.
  2. Upright vacuum mode with the power unit at the bottom of the stick (Comfort Mode).  Moving the power unit to just above the floorhead turns the Miele Triflex HX1 Pro into a cordless upright. As the power unit is closer to the floor, the HX1 feels more balanced and less tiring to hold, so it’s a great option for cleaning big areas of floor. The Miele is also freestanding in this configuration. The vacuum is more cumbersome to use in tight areas when in Comfort Mode though.
  3. Handheld mode with the stick detached (Compact Mode).  Compact Mode (effectively a handheld vacuum) is handy for cleaning cars, pet beds, furniture, stairs, and other awkward locations. Using this mode for too long can be tiring though, due to the relatively heavy power unit.

While all three modes have their pros and cons, having the option to switch between them makes the HX1 one of the most versatile cordless vacuums on the market. Moving between the different setups can feel fiddly at first, but it becomes easier once you get the hang of it.

As you would expect from Miele, the Triflex HX1 Pro is durable, sturdy, and easy to take apart. There’s also an audible “click” when slotting parts back together.


Miele has included their excellent HEPA lifetime AirClean filter with the Miele Triflex HX1 Pro. This is an efficient lifetime filter that removes up to 99.999% of small particles from the air, which reduces the chance of an allergic reaction to dust, pet dander, or pollen.

It’s important to keep in mind that this is a bagless cordless vacuum though. While the HX1 does a great job at filtering small particles into the bin, these can easily escape during the emptying process. That’s why we recommend a bagged vacuum for people with allergies.

Emptying & Cleaning

The Miele HX1 series has a simple trap door emptying system. To empty the vacuum, you just remove the canister and open the door over a bin.

While it’s important for a cordless vacuum to be easy to empty, the Miele isn’t the most hygienic system we’ve seen. There’s no internal collar to push out fluff and hair, so you sometimes need to do this by hand. Like all bagless vacuums, dust and dirt can also escape when emptying, and it can feel unnecessarily fiddly to remove the dust container.

It’s not a terrible system and usually does the job. But it’s an area where the Triflex lags behind other models, such as the Dyson V10 or V11.

Battery Life

One of the biggest differences between the HX1 Pro and other models in the series is that the Pro comes with two swappable batteries. As each battery has a 60 minute running time on a single charge, the HX1 Pro can theoretically clean for a whopping two hours, which is considerably longer than nearly every other cordless vacuum on the market.

As with all cordless vacuums, this run-time is only applicable when using the lowest power mode and a non-motorised tool. For comparison, the highest suction setting and primary floorhead will drain a battery in around 17 minutes.

This still means you get nearly 35 minutes of high-power vacuuming when using the spare battery though. And the “medium” power setting is more than powerful enough for most tasks, which further increases run-time.

Additionally, each battery takes around 4 hours to charge. This is a bit faster than the Dyson V11, but slower than the Halo Capsule or Samsung Jet 90 Pet.

Note: The HX1 Pro comes with a battery charger cradle. This allows you to recharge the second battery while vacuuming.

Miele Triflex HX1 Pro Tools & Accessories

Three in one Miele design

The Miele Triflex HX1 Pro comes with several of Miele’s accessories, such as a charging cradle and a mount for storage. It also includes a motorised floorhead and the standard non-motorised tools you expect from a modern vacuum cleaner.


The Miele Triflex HX1’s primary floorhead is called the Electric Brush Multi Floor XXL. This is a wide floorhead with a powered brush bar and strong LED lights, which we think is one of the best cordless floorheads on the market. It also automatically adjusts the brush bar speed depending on the floor type (when in medium or high power modes,) which is useful if your home has different types of floor.

A downside of the HX1 Pro is that it doesn’t come with a motorised pet tool (Miele calls this the “Electric Brush Electro Compact”.) We think this is a big oversight from Miele, as you would expect to receive a turbo tool when buying such an expensive vacuum cleaner. If you have pets, or just want to clean stairs or car interiors more deeply, then you’ll need to either purchase the Cat & Dog version or buy the tool separately.

Other Tools and Accessories

Aside from the motorised floorhead, the Triflex HX1 Pro comes with a dusting brush (synthetic bristles,) upholstery nozzle, and crevice nozzle. These slot into place with a satisfying click, and are easy to swap as needed. Miele has also included both a wall mount and battery charging tray with the Pro.

While the tools are built to a high standard, we can’t help feeling that Miele should be providing a more extensive selection for such a premium price.

Suction Power & Cleaning Performance

The Miele Triflex HX1 Pro provides excellent cleaning performance on nearly all floor types. It also has strong suction power, due to Miele’s Vortex Technology. Whether you need to clean carpets, tiles, or laminate, the combination of strong suction and high-quality floorhead makes the Pro one of the best cordless vacuums on the market.

As we mentioned earlier, there are three suction settings – low, medium, and high. The lowest power mode is still relatively powerful, although you’ll probably use the medium mode for most cleaning tasks. High mode greatly reduces battery run-time, so should be saved for stubborn dirt.

The medium and high powered modes also activate the HX1’s adaptive technology. This adjusts the speed of the brush bar depending on the type of floor, which is handy for preventing scattering on hard floors. It’s not as advanced as the adaptive suction systems found on the latest Dyson or Tineco vacuums, but it’s still a useful feature.


With its powerful brush bar and strong suction, the Miele is brilliant for cleaning carpets. The brush digs deep into carpet fibres to remove more dirt and dust, while the headlights illuminate anything you might have missed.

A minor drawback is that the suction power can make the vacuum difficult to push when on its highest setting, although it’s comfortable to use when on the medium power mode.

Hard Floors

Just like with carpets, the Miele Triflex HX1 Pro is an excellent cordless vacuum for cleaning hard floors. The suction is strong enough to pick up both large and small debris on hard surfaces, while the adaptive brush bar speed reduces the chance of scattering. It also has enough power to suck up dirt from between floorboards.

If we had one complaint, it’s that the Triflex series seems to struggle more on tiles than other surfaces. It’s no slouch even when cleaning tile though.


On the one hand, having a handheld mode makes the Triflex a convenient choice for cleaning stairs and other awkward locations. As we’ve mentioned, the vacuum also has plenty of cleaning power, even when using a non-motorised tool.

The lack of a motorised turbo tool makes the Miele Triflex HX1 Pro less effective at cleaning carpeted stairs than many of its competitors though. It’s also quite a heavy cordless vacuum, so your wrist may become tired when doing a deep clean.

Pet Hair

The main floorhead does a great job at picking up pet hair from both carpets and hard floors. Most hair clumps are picked up in a single pass, although the hair can sometimes get caught in the canister and need to be removed by hand.

There’s no pet turbo tool though. You’ll need to use the non-motorised upholstery tool for cleaning pet hair on sofas or stairs, which is much less effective than a tool with a powered brush bar. For this reason, we recommend that pet owners choose the HX1 Cat & Dog version, unless you really need the additional battery.

Miele Triflex HX1 Pro Price & Value for Money

There’s no doubt that the Miele Triflex HX1 Pro a brilliant cordless vacuum cleaner, but it’s also one of the most expensive on the market.

For comparison, it currently has a similar price to the Dyson V11 Outsize, which is the larger model in the V11 range. Unlike the V11 Outsize, however, the Miele doesn’t include an LCD screen, has a much smaller dust capacity, and doesn’t have a pet turbo tool. It also only has a single floorhead, while the Dyson includes the Soft Roller for hard floors.

The Pro is also considerably more expensive than the HX1 Cat & Dog, despite having similar features and fewer tools (the Cat & Dog includes a pet turbo tool.)

For this reason, it’s hard to recommend the HX1 Pro over the HX1 Cat & Dog version. The only reason to spend more to buy it over the other versions of the HX1 is if you really need the extra battery. Otherwise the pet turbo tool and lower price of the Cat & Dog make it a better option.

Frequently Asked Questions

How Much Does the Miele HX1 Pro SMML0 Weigh?

The HX1 Pro weighs approximately 3.6kg. This makes it lighter than cylinder or upright vacuum cleaners, but heavier than most cordless models.

Does the Miele Have a HEPA Filter?

Yes, this model includes Miele’s HEPA AirClean lifetime filter. Make sure you empty it outside if you have allergies, however, as the bagless design can allow fine dust (and other allergens) to escape.

Where Can You Buy It?

The HX1 series is available at a wide range of online retailers. Prices vary over time, so it’s worth checking Amazon, John Lewis, AO, and other major retailers to find the best price (this is true when buying all home appliances.)

Miele Triflex HX1 Pro Verdict

The Miele Triflex HX1 Pro is an excellent cordless stick vacuum cleaner. It provides exceptional cleaning performance on all surfaces, boasts a long two hour run-time (when you swap batteries,) and has a HEPA filter for improved allergen retention. The 3-in-1 design also makes it a versatile choice.

There are some drawbacks to the HX1 range though. The 0.5 litre dust capacity is relatively small, so you’ll need to empty it frequently. It’s also quite a bulky model in comparison to the lightest cordless vacs.

We also think that the Miele Triflex HX1 Cat & Dog provides better value than the Pro version. It’s a lot cheaper and comes with a pet turbo tool, which isn’t included with the Pro version. The downside to the Cat & Dog version is that you don’t get two batteries, although a single battery still provides up to 60 minutes of run-time.

With that said, the Miele Triflex HX1 Pro provides excellent cleaning power and a two hour run-time, so it’s still one of the best vacuums on the market.
