The Miele Triflex HX2 Pro/Cat & Dog is a cordless vacuum. It's the follow-up to the Miele Triflex HX1 and carries over the same reconfigurable design. You can change the position of its motor unit, wand, and handle, allowing you to use it as an upright, stick, or handheld vacuum. However, it improves on its predecessor in a couple of useful ways, with a more powerful suction motor, a considerably longer battery life, and a redesigned filter system that allows you to dislodge any stuck-on debris without removing it from the dirt compartment.

Our Verdict

8.1 Bare Floor

The Miele Triflex HX2 is great for bare floors. It easily clears away pet hair and small debris on this surface type, though it can have some trouble dealing with large piles of bulky debris. It's well-built and quite maneuverable, too, with a unique three-in-one design that you can configure to suit different cleaning tasks. That said, it can be difficult to maneuver under tables and couches when the vacuum is configured as an upright, with the bulky motor unit placed low to the ground. It's also equipped with a tiny dirt compartment that you frequently need to empty.

Pros
  • Great overall debris-pickup performance.
  • Good build quality.
  • Good battery performance.
Cons
  • Small dirt compartment.
  • Can't clear stains.
8.0 Low-Pile Carpet

The Miele Triflex HX2 is impressively effective on low-pile carpet. Its surface detection system allows it to automatically increase suction power on carpeted floors, where it easily clears away small and large debris, not to mention pet hair. It feels quite well-built, especially for a cordless stick vacuum, incurs very few recurring costs, and is fairly easy to maintain, with handy quality-of-life features like its 'ComfortClean' filter cleaning dial. Unfortunately, its small dirt compartment needs to be emptied often.

Pros
  • Great overall debris-pickup performance.
  • Good build quality.
  • Good battery performance.
Cons
  • Small dirt compartment.
8.3 High-Pile Carpet

The Miele Triflex HX2 is a great option for cleaning high-pile carpet. It has little trouble clearing away pet hair and fine and large debris. Battery performance is also quite good for a cordless stick vacuum. Better yet, the Pro variant of the HX2 comes with a second battery, which is great for longer cleaning jobs requiring more power. It also has a lightweight, highly configurable design with a surface detection system that allows it to change its brushroll speed when cleaning carpeted floors. Unfortunately, it has a small dirt compartment, and it can get stuck on super-plush shag-pile carpets and rugs.

Pros
  • Great overall debris-pickup performance.
  • Good build quality.
  • Good battery performance.
Cons
  • Small dirt compartment.
7.3 Pets

The Miele Triflex HX2 is a decent choice for pet owners. While a small amount of pet hair can get stuck in its wand, it still has little trouble dealing with hair on carpets and bare surfaces like hardwood or vinyl. It's also equipped with a HEPA-rated filtration system that's very effective in sealing in fine allergens like pet dander. That said, the dirt compartment's small capacity means you'll need to empty it out pretty often, so you'll expose yourself to a fair amount of fine dust and grit when shaking it out. The HX2's upholstery nozzle isn't the best attachment on the market for dealing with short strands of hair, though thankfully, a mini turbo brush tool is available separately. This attachment is also bundled with the HX2 Cat & Dog variant.

Pros
  • Clears pet hair on all surfaces.
  • HEPA filter system.
Cons
  • Can't clear stains.
  • Upholstery nozzle struggles with short strands of pet hair on fabric.
8.7 Stairs

The Miele Triflex HX2 is excellent for cleaning stairs. It isn't the lightest cordless stick vacuum on the market, but feels well-built. Besides, in the grand scheme of things, it's still pretty portable, and you won't have too much trouble carrying it up and down flights of stairs. It can be fitted with a wand-mounted tool clip, so you can quickly swap attachments while you're on the move.

Pros
  • Highly configurable design.
  • Great overall debris-pickup performance.
  • Good build quality.
  • Good battery performance.
Cons
  • Small dirt compartment.
8.1 Cars

The Miele Triflex HX2 is great for cleaning the inside of your car. Its cordless design ensures you don't need to stay close to an outlet to deal with messes in your car. You can quickly reconfigure it into a compact handheld to clean small areas, and it comes with a few handy accessories. These include a crevice cleaner to tackle debris in hard-to-reach corners, an upholstery cleaner to help clear debris from car seat fabric, and a dusting brush for dealing with dust on easily scratched plastics.

Pros
  • Highly configurable design.
  • Good build quality.
Cons
  • Small dirt compartment.
6.5 Workshop

The Miele Triflex HX2 isn't really designed for workshop cleaning. While it doesn't have any trouble dealing with household debris, it'll be damaged if you use it to clean heavy-duty debris like wood or metal shavings, and it can't suck up liquids.

Pros
  • Great overall debris-pickup performance.
  • Good battery performance.
Cons
  • Small dirt compartment.
  • Can't clear stains.
  • Not meant for liquid spills.

Compared To Other Vacuums

The Miele Triflex HX2 is a premium cordless vacuum. It represents a sizeable upgrade over the older Miele Triflex HX1, with a more efficient motor, considerably longer runtime, and a redesigned filtration system. It makes for a compelling alternative to other high-end cordless stick vacuums, especially if you want something that feels sturdier than the norm, but note that you'll have to contend with a tiny dustbin and a fairly limited attachment set.

If you're looking for alternatives, check out our recommendations for the best cordless stick vacuums, the best lightweight vacuums, and the best cordless vacuums.

Dyson V15 Detect

The Dyson V15 Detect and Miele Triflex HX2 Pro/Cat & Dog each have their own advantages. The Miele feels like a more premium product, with better build quality and fewer parts that need periodic cleaning. Meanwhile, the Dyson has the advantage in terms of raw performance. It also has a much bigger dustbin than the Miele.

Dyson V12 Detect Slim

The Dyson V12 Detect Slim and the Miele Triflex HX2 Pro/Cat & Dog are fairly evenly matched cordless stick vacuums. The Dyson is lighter and easier to maneuver around obstacles and comes with a broader assortment of tools. Conversely, the Miele feels far more robust and has a slightly bigger dirt compartment. It also makes less noise while running.

Miele Triflex HX1

The Miele Triflex HX2 Pro/Cat & Dog is a pretty comprehensive upgrade over the Miele Triflex HX1. The HX2 features a more efficient motor and significantly better battery life. It also has a handy 'ComfortClean' filter cleaning system, allowing you to dislodge any debris stuck in the filter system without getting your hands dirty. That said, the HX1 has a marginally higher-capacity dustbin, and its lower-powered motor makes it easier to maneuver on thick carpeting.

Test Results

Design
Build Quality
Vacuum Type
Stick/Handheld

The Miele Triflex HX2 is a sturdily-built cordless vacuum. It's similar in quality to its predecessor, with a body made of thick, high-grade plastic, which doesn't creak when it's moved around. It doesn't really differ much in overall appearance either, with only slightly more pronounced gold accents, a dustbin made of darker, more opaque plastic, and a redesigned filter system, which also features an eye-catching gold finish. The vacuum's color depends on the trim you select: the basic HX2 is made of glossy white plastic, the mid-range Cat & Dog has a glossy black finish, and the flagship Pro has a matte grey body. Like its predecessor, the handle does feel somewhat cheap and hollow.

All parts clip together and come apart fairly intuitively, though its handle takes a bit of force to remove, and you'll need to make sure the dustbin is precisely seated in its slot when reinstalling it.

Design
User Maintenance

This Miele Triflex HX2 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 unlock it. Turning the lid further releases the compartment's bottom door, allowing you to empty any debris over a garbage can. You must empty it when it gets full and occasionally clean it with water and dish soap, but remove the pre-filter first.
  • Pre-filter: You need to completely rotate the dirt compartment's lid counterclockwise until it releases and can be lifted out. The HX2 also features a 'ComfortClean' feature; turning a dial on top of the dustbin lid in a counterclockwise direction rotates a plastic lattice inside the pre-filter system to dislodge any stuck-on debris. You can see that feature in action here. The user manual recommends giving the dial ten 180-degree rotations regularly to ensure there's no significant debris buildup. You should also take the filter completely out of the vacuum to give it a thorough clean every three months.
  • Fine dust filter: The fine dust filter is a bit of a hassle to remove. You need to remove the dustbin from the body, release the pre-filter system, and rotate the 'ComfortClean' dial in a clockwise direction, lifting the fine dust filter out of the pre-filter assembly. In practice, it can take quite a bit of force to spin the dial in this direction. Once you remove it, tap it against the edge of a trash can to dislodge any embedded dirt or dust, but don't rinse it under water. You should clean it every three months.
  • Multi-floor XXL floorhead: You can flip the vacuum head over to cut out any hair wraps with scissors. You can remove the brushroll by lifting the brushroll cover on the left side of the floorhead and then simply pulling the roller out. This Pro variant of the HX2 comes with two interchangeable brushrolls, one with bristles for cleaning carpets and the other being a soft nylon roller intended for hard floors. You can cut out any tangled hair in the bristled roller by cutting along the embossed grooved on the roller. You can do the same for the soft roller, too.

Any part you can wash under water should completely dry before reinstallation.

  • Fine dust filter: Even though Miele advertises this filter under the name of 'HEPA Lifetime filter,' it doesn't actually last the lifetime of the vacuum; you should replace it after three years of use. You can buy a new one here.

At the very least, the dustbin is easy to release and empty.

The Miele Triflex HX2 is very portable. While it's a little heavier than alternatives like the Dyson Gen5detect, it's by a slim margin. Using it in its upright configuration, with the motor unit placed low to the ground, puts very little weight in your hand, minimizing fatigue. However, using it in its stick configuration, with the motor unit sandwiched between the handle and wand, does increase the weight in hand to 4.89 lbs (2.22 kg).

Battery performance is great. The flagship Pro variant of the HX2 comes with a pair of batteries, so you can swap in a freshly-charged pack if you run out. A single fully-charged battery yields a maximum runtime of over an hour when you use the vacuum in its 'Min' mode with only its crevice tool attached. Using the HX2 in its high-power 'Max' mode with the floorhead attached can run a single battery dry in about 15 minutes. In both respects, these figures are similar to market standouts like the Dyson Gen5detect. It also handily outperforms the older Miele Triflex HX1 in this regard. The vacuum also features a trio of battery indicator lights, which gradually turn off as the charge level drops.

The Miele Triflex HX2 has a couple of quality-of-life features. Three power settings are available, aside from '0', which is the off setting. In increasing order of suction power, there's the low-power 'Min,' the default 'Eco,' and the high-power 'Max.' You can switch this setting via a slider on its handle. Like its predecessor, the HX2 has a floor detection system, which allows it to automatically adjust the brushroll speed and suction power depending on the surface you're cleaning; this feature works regardless of the power setting you have the vacuum set to. It's worth noting that this vacuum's Cat & Dog and Pro variants come with a floorhead with a headlight to illuminate darker corners. The standard HX2 has a simpler floorhead with no headlight.

This vacuum can deliver excellent performance on bare floors if you set it up properly. This vacuum has no trouble dealing with small debris, like rice, when set to its default 'Eco' power mode and used with its soft roller. However, if you plan on using it to deal with large amounts of bulky debris, similar in size to whole pieces of cereal, it's best to use the vacuum with its bristled roller and the suction mode set to 'Max.' Using any other configuration will result in large debris being pushed around at the front of the floorhead, as seen here, or stuck in the floorhead and causing the roller to jam, as seen here.

The Miele Triflex HX2 does an impressive job of cleaning low-pile carpet when set to its 'Max' mode with the bristled roller. It picks up a good amount of fine debris like baking soda and larger material like sand, though you may need to make an extra pass to suck up all of it.

This vacuum performs outstandingly well on high-pile carpet when set to its 'Eco' mode with the bristled roller. While you might assume that the higher-powered 'Max' mode would be helpful on this surface type, it's actually more of a hindrance, causing the brushroll to get tangled up in the carpet fibers. Instead, it's best to use the default 'Eco' mode, where you can easily maneuver the vacuum on thick carpets and clear away most fine and large debris.

This vacuum has decent real-world suction performance. It can't compete with standouts like the Dyson Gen5detect in this respect, though its upgraded Digital Efficiency motor yields significant performance gains over the older Miele Triflex HX1. While it isn't the most powerful cordless vacuum on the market, it won't have too much trouble lifting away lightweight debris embedded in carpet fibers or trapped in crevices.

Performance
Maneuverability

The Miele Triflex HX2 has great maneuverability. Using the vacuum in its upright configuration keeps weight low to the ground, making it very easy to maneuver. However, cleaning under low-lying furniture like couches and tables with the vacuum set up this way can be tricky. Its self-adjusting brush speed makes it easy to transition from cleaning bare floors to carpets. While it feels easy to use for the most part, it's worth noting that its floorhead is noticeably bulkier than that of a comparable Dyson, like the Dyson V15 Detect. It also gets bogged down on thicker carpets more easily than the older, less powerful Miele Triflex HX1.

This vacuum's pet hair-cleaning performance on fabric furniture is okay. It'll take a few passes to clear away most pet hair with its upholstery tool, and even then, some shorter strands may be left behind. If you have a pet, it might be worth going for the Miele Triflex HX2 Cat & Dog variant, which comes bundled with a mini turbo brush tool. The vacuum's side-exit exhaust can also blow hair away when cleaning furniture, which is annoying.
