The Miele Triflex HX1 is a cordless vacuum with a unique three-in-one design. You can switch between using it as an upright, stick, or a compact cordless vacuum quickly and easily, courtesy of its intuitive construction. It performs superbly well on bare floors and clears an impressive amount of debris on low and high-pile carpet. It's also easy to maintain and incurs very few recurring costs. Unfortunately, it has a small dirt compartment that needs frequent emptying. Otherwise, if you're looking for a feature-packed, highly versatile cordless vacuum, this is a great option.

Our Verdict

8.9 Bare Floor

The Miele Triflex HX1 is excellent for bare floors. It sucks up pet hair as well as small and bulky debris like rice and cereal easily. It's also well-built and highly maneuverable, with a unique three-in-one design that can be configured to suit different cleaning tasks. While it's easy to maintain, it does have a small dirt compartment that you need to empty quite frequently.

Pros
  • Superb bare-floor performance.
  • Clears pet hair on all surfaces.
  • Good build quality.
  • Few recurring costs.
Cons
  • Small dirt compartment.
8.0 Low-Pile Carpet

The Miele Triflex HX1 is great for low-pile carpet. It clears pet hair without a problem and does a good job of sucking up material like sand or baking soda. It's also well-built and incurs very few recurring costs. Unfortunately, its small dirt compartment needs to be emptied often, which can interrupt your cleaning duties.

Pros
  • Clears pet hair on all surfaces.
  • Good build quality.
  • Few recurring costs.
Cons
  • Small dirt compartment.
7.9 High-Pile Carpet

The Miele Triflex HX1 is very good for high-pile carpet. It clears pet hair and quite a bit of coarse, sand-like debris. It also has a lightweight, highly configurable design with a self-adjusting vacuum surface adjustment feature. Unfortunately, it has a small dirt compartment, and it may take an extra pass to fully clear fine material like baking soda from this kind of surface.

Pros
  • Clears pet hair on all surfaces.
  • Good build quality.
  • Few recurring costs.
Cons
  • Small dirt compartment.
  • Can struggle slightly with fine debris on high-pile carpet.
8.8 Pets

The Miele Triflex HX1 is an amazing choice for pet owners. It sucks up pet hair without difficulty on everything from bare floors to high-pile carpet. It's also fairly easy to maintain, with a removable brushroll that makes clearing hair wraps simple. While it lacks an onboard HEPA filter, its fine dust filter is advertised as being able to trap most fine particulates.

Pros
  • Clears pet hair on all surfaces.
  • Good build quality.
  • Few recurring costs.
Cons
  • No dedicated pet grooming tool.
8.9 Stairs

The Miele Triflex HX1 is excellent for cleaning messes on stairs. It doesn't weigh very much and can be easily carried up and down staircases. Its cordless design gives you a theoretically indefinite range, and you can configure it as a traditional stick vacuum to give it a slightly slimmer profile.

Pros
  • Lightweight, highly configurable design.
  • Good build quality.
  • Few recurring costs.
Cons
  • Small dirt compartment.
8.3 Cars

The Miele Triflex HX1 is great for cleaning messes inside of your car. It can be converted into a compact handheld, and it comes with a crevice cleaner to tackle debris in hard-to-reach areas. It also comes with an upholstery cleaner to help clear debris from car seat fabric. Since it's cordless, you don't need to stay close to an outlet to deal with messes in your car.

Pros
  • Lightweight, highly configurable design.
  • Good build quality.
  • Few recurring costs.
Cons
  • Small dirt compartment.
  • 8.9 Bare Floor
  • 8.0 Low-Pile Carpet

Build Quality

The Miele Triflex HX1 is very well-built. It's mostly made of high-grade plastic, though its wheels are made of rubber. Overall, it looks and feels quite premium, and even its dirt compartment is made of a sturdy-feeling plastic. That said, its handle feels somewhat cheap and hollow. Reconfiguring the vacuum or fitting new attachments is fairly simple, too.

Design
User Maintenance

The Miele HX1 is quite easy to maintain, as the few parts that require regular servicing are readily accessible.

  • Dirt compartment: You need to twist the dirt compartment's lid counterclockwise to release it. Turning the lid further releases the compartment's bottom door, allowing you to empty out any debris over a garbage can. It needs to be emptied out when it gets full and occasionally cleaned out with water and dish soap, but be sure to remove the pre-filter first.
  • Fine dust filter: You can remove this part by pulling on a tab on top of the dirt compartment. It should be cleaned at least once a month by tapping it against a trash can to dislodge any stuck-on debris.
  • Pre-filter: You need to completely rotate the dirt compartment's lid counterclockwise until it releases and can be lifted out. No specific maintenance interval is specified, so it should be cleaned when needed either by tapping it over a trash bin or using a cleaning brush on it for a more thorough clean.
  • Electrobrush/Brushroll: You can flip the vacuum head over to cut out any hair wraps with scissors. You can remove the brushroll by pulling a sliding lock to open the brushroll cover and then simply pulling the component out.

The vacuum's motor protection filter doesn't need to be cleaned, but it does need to be removed to access the pre-filter. Also, any part that can be washed under water should be left to dry completely before it can be reused.

This vacuum has good battery performance. In its 'max.' power setting, it should supply roughly 18 minutes of runtime. In its '1' low-power mode, that continuous runtime extends to over 30 minutes. It also has a trio of battery indicator lights that clearly show its current charge status. In normal operation, the three lights gradually turn off as its battery drains, with the last one flashing to show that it's dropped below 10% capacity. If you want a vacuum with a longer maximum battery life, take a look at the Samsung Jet 90 Complete.

The Miele Triflex HX1 has a couple of quality of life features. There are three power settings available, aside from '0', which is used to turn the vacuum off. In increasing order of suction power, they are '1', '2', and 'max.'. This setting can be switched via a slider on its main handle. Using the '2' or 'max.' power modes also enables its automatic surface-type adjustment feature, which allows it to select the optimal brush power by itself, and even stop the brushroll if it detects that something is tangled in it, like rug tassels.

The SMUL0 variant of the Miele Triflex HX1 has a couple of tools and accessories. It comes with an upholstery cleaner to remove debris from fabric-lined furniture, a soft-bristle dusting brush, and a crevice tool to tackle messes in tight corners. The brushroll also has an automatic shutoff feature that prevents it from getting tangled with obstacles like rug tassels. If you're looking for a stick vacuum with more tools and brushes in the box, including a turbo brush, then check out the Dyson Micro 1.5kg.

Design
Alternative Configuration

Unusually, the Miele Triflex HX1 has two alternative configurations aside from its default upright mode. You can use it as a traditional stick vacuum by moving the main body above the wand and fitting the handle in place or remove the wand entirely to use it as a compact handheld.

The Miele Triflex HX1 has great maneuverability. The vacuum itself is lightweight and easy to push around. Its self-adjusting brush power makes it easy to transition from cleaning bare floors to carpets, and it stops the brushroll from spinning if it detects that it's about to get tangled on obstacles like rug tassels. Switching configurations is easy and intuitive, though since it's a little bulky at the connection point between its wand and nozzle, it can be a little tricky to clean under low-lying furniture like couches and tables.

Compared To Other Vacuums

The Miele HX1 is a highly configurable cordless vacuum. It offers versatile cleaning performance and a design that can be quickly adapted to suit different cleaning tasks. It also has few recurring costs and is simple to maintain, though its small dirt compartment needs to be emptied frequently. If you're looking for other options, take a look at our list of recommendations of the best cordless stick vacuums, the best lightweight vacuums, and the best cordless vacuums.

Dyson V11 Animal

The Miele Triflex HX1 is superior to the Dyson V11 Animal. The Miele feels better-made, is easier to maintain and performs better on bare floors and low-pile carpet. It also feels lighter in your hand and is more maneuverable. Conversely, the Dyson has a longer maximum battery life, more tools and brushes, a bigger dirt compartment, and slightly better performance on high-pile carpet.

Dyson V15 Detect

The Miele Triflex HX1 and Dyson V15 Detect each have their advantages, so one may suit you better than the other depending on your needs. The Miele is better-built, easier to maintain, feels lighter, and is more maneuverable. It also has an automatic surface type adjustment feature that stops the brushroll from spinning if it detects that something has gotten tangled in it. Meanwhile, the Dyson delivers superior performance on low and high-pile carpet, comes with more tools and accessories, has a larger dirt compartment, and lasts longer on a charge when run in its most energy-efficient power setting.

LG CordZero A9 Ultimate

Meanwhile, the LG is lighter and has a longer maximum battery life, though it takes much longer to recharge.

Dyson V8 Animal

The Dyson V8 Animal and Miele Triflex HX1 each have their own advantages, so one may suit you better than the other depending on your needs. The Dyson incurs virtually no recurring costs, has a bigger dustbin, comes with more tools and brushes, and is a little more effective on low-pile carpet. Conversely, the Miele has a more configurable three-in-one design that allows you to use it as a handheld, stick, or upright vacuum. It also feels better-built, is easier to maintain, can be maneuvered with less difficulty, and has an automatic surface type adjustment feature that allows it to speed up, slow down, or even stop the brushroll if it detects that something is tangled in it.

The Miele Triflex HX1 is a better vacuum than the Samsung Jet 90 Complete for most uses. The Miele has a much better build quality, fewer recurring costs, and is easier to maintain. Its performance on bare floors is somewhat better and it has an automatic surface type adjustment feature. On the other hand, the Samsung delivers a significantly better performance on high-pile carpets, where it's more effective at picking up fine debris like baking soda.

Dyson Cyclone V10 Absolute

The Miele Triflex HX1 and Dyson Cyclone V10 Absolute are fairly evenly matched, and you may prefer one over the other depending on your needs. The Miele is better-built, easier to maintain, more maneuverable, and performs significantly better on bare floors. Meanwhile, the Dyson has a larger dirt compartment, a slightly longer maximum battery life, and far more tools and accessories.

Dyson Outsize Absolute+

The Miele Triflex HX1 is a better vacuum than the Dyson Outsize Absolute+. The Miele is better-built, less demanding in terms of maintenance, offers superior performance on bare floors and low-pile carpet, and is easier to maneuver. It also has a unique three-in-one design that makes it a little more versatile. Meanwhile, the Dyson has a larger dirt compartment that doesn't need to be emptied as often and comes with more tools and brushes, not to mention a second battery, which gives it a significantly longer total runtime.

Shark Rocket Pet Pro with MultiFlex IZ163H

The Shark Rocket Pet Pro with MultiFlex IZ163H and Miele Triflex HX1 have different strengths, and which you prefer may come down to your personal needs and preferences. The Miele is better-built, has an automatic surface type adjustment feature, and a slightly more configurable design. Both perform very well in terms of suction performance, with the Miele clearing more fine debris on carpeted floors and the Shark dealing with coarse sand-like material more easily. The Shark also has a larger dirt compartment, a longer maximum battery life, and charges faster.

Shark Vertex Lightweight Cordless

The Miele Triflex HX1 is a more versatile vacuum than the Shark Vertex Lightweight Cordless. The Miele is better-built, easier to maintain, and performs better on all surface types. It also has fewer recurring costs. Meanwhile, the Shark has a bigger dirt compartment, a longer battery life, and charges faster.
