Compare Dyson V12 Detect Slim Vacuum vs Miele Triflex HX2 Pro Cordless Stick Vacuum

Upholstery and above-floor cleaning were strong, especially with the Hair Screw or mini motorized tool for couches, mattresses, pet beds, and car crevices.

Above-floor use was limited by weight and balance, with reviewers noting high cleaning could become a struggle.

Hair-wrap resistance was mostly excellent with Motorbar and Hair Screw tools, but long-term use showed hair can still spool on the Fluffy head sides.

Hair-wrap resistance was sharply mixed: one reviewer saw no wrap, while others complained of tangled hair or missing anti-tangle tech.

Weight was one of the most praised attributes; reviewers repeatedly highlighted the V12 as light, compact, and easy to carry.

Weight impressions depended on configuration: some found it light or easier on the hands, while others found high or handheld use tiring.

Controls were usually praised for the single power button and useful display, with one reviewer preferring a trigger and a few noting some particle data was less useful.

Controls were mixed: one reviewer liked thumb-reachable slider controls, while another found the slider cumbersome when aiming for Eco mode.

Hard-floor large-debris intake was generally very good with the Fluffy head, though one review noted larger kibble could challenge it.

Large hard-floor debris performance was inconsistent: some tests cleared cereal or rice in one pass, while others saw cereal fling or push ahead.

Heavy-duty suitability was limited; reviewers viewed the V12 as better for maintenance cleaning than thick carpets, large homes, or heavy shedding.

In a pet shelter entrance-mat test with heavy traffic, performance was described as decent despite some stubborn hair remaining.

Emptying ranged from easy and clean in several reviews to frustrating when the small bin forced frequent emptying or manual hair removal.

Emptying ranged from touch-free praise to strong frustration; several reviewers called it fiddly, messy, tedious, or the biggest long-term hassle.

Area rug handling was mixed: some reviewers found it useful on rugs, while others said the Motorbar could trip, pull, or stall on certain rugs.

Area-rug and floor-transition handling was generally positive when the floorhead automatically adjusted power or brush behavior across surfaces.

The convertible handheld design was praised for dramatically improving handheld maneuverability compared with larger cordless vacuums.

The convertible 3-in-1 layout drew mixed responses: many liked the flexibility, but several found switching modes fiddly or less useful than expected.

Storage feedback was mixed: wall-dock storage was convenient, but freestanding stability was poor.

Self-standing storage was widely liked, especially in upright/Comfort mode, though one reviewer noted it only stands by itself in that configuration.

Maneuverability was a major strength, with repeated praise for steering, flexibility, and easy handling.

Handling was split by configuration and reviewer: Comfort mode lowered hand weight and felt easy to push, but others found turning clumsy or poorly flexible.

Cyclone performance was mixed in one review because the smaller cyclone array contributes to lower suction than V11 or V15.

One review praised the Vortex-style cyclone path for separating fine dust from coarser dirt before emptying.

The low-profile cleaning head was praised for lying nearly flat and reaching beneath furniture.

One retailer review said the pivoting design could work under furniture with about four inches of clearance.

Comparative performance was favorable against smaller or older Dyson models, while the V12 remained below larger flagship Dysons for raw power.

Comparative results were mixed: one reviewer placed its cleaning among the best tested, while another found it weaker than Dyson at spill pickup.

Innovation was praised around practical, useful Dyson features such as the laser, detect tech, and lightweight engineering.

One reviewer treated the self-standing cordless configuration as a distinctive trick rarely seen in cordless stick vacuums.

Versatility was strong because the V12 works as a floor vacuum and above-floor cleaner with the right tool for many jobs.

Versatility was a major theme, with reviewers praising multiple configurations, while some felt the 3-in-1 concept delivered less real benefit than promised.

Hair-removal channel issues were mixed, with mostly good anti-tangle results but some reports of hair wrapping on axles or pooling at head edges.

One reviewer specifically complained that freeing hair from the brush bar was a nuisance.

High-pile or deeper carpet performance was mixed, with some strong test results but several cautions that it is not ideal for thick or deep carpet.

Long-pile wool carpet was more demanding, with one reviewer saying the lowest setting did not cut it.

Overall opinion was strongly positive across most reviews, framing the V12 as a lightweight, high-tech, high-performing cordless with clear bin and price tradeoffs.

Overall verdicts ranged from premium praise to one long-term non-recommendation; most reviewers liked cleaning power but disagreed on whether the drawbacks were acceptable.

Value was mixed: reviewers liked getting premium Dyson tech below flagship prices, but repeatedly called the V12 expensive and less compelling for budget buyers.

Value was polarized: reviewers admired premium performance and build but repeatedly questioned the high price, especially given the bin, weight, and feature tradeoffs.

Noise feedback was mixed: some found it not very loud or quieter than upright vacuums, while another measured loud boost-mode operation.

Noise impressions were favorable overall: reviewers described it as relatively quiet, less irritating than typical vacuums, and quieter than a Dyson V10.

Hair pickup on carpets and rugs was strong in lab and user tests, especially with pet hair and long hair.

Carpet hair pickup impressed in multiple tests, including visible pet hair and combed-in cat hair.

Cordless convenience was praised in user experience terms, especially avoiding cords and moving easily between rooms.

Cordless use was praised for freedom of movement and as a plausible replacement for a plug-in cleaner.

Under-furniture pickup was strong thanks to the slim, low-profile head and easy steering.

Under-furniture use benefited from the handstick configuration and helpful lighting, making low and high reach more practical.

Ease of use was a standout, with reviewers calling the vacuum easy to steer, easy to grab, and enjoyable to use.

Ease of use was generally good in simple use and floor transitions, though some reviewers separated that from the less convenient bin and mode-switching issues.

Pet performance was generally positive, helped by Motorbar and Hair Screw tools, but a few reviewers cautioned that heavy pet hair or large homes may push its limits.

One review found pet-hair performance generally decent, especially on hard floors and medium-pile carpet, while noting tougher entrance matting left some stubborn hairs.

Maintenance was mixed: general cleaning was simple for some, but small-bin clogs, filter washing, and manual hair removal made ownership fussier for others.

Maintenance was mixed: reviewers liked easy filter care or self-cleaning features, but one long-term user found filter cleaning could be easier.

Runtime was context-dependent: eco/low settings were adequate, but boost and large-home deep cleans drained the battery quickly.

Runtime was mixed: extra batteries helped, but reviewers found preferred settings much shorter than headline claims.

Crevice and groove pickup was strong in several tests and real-world use, though deep cracks sometimes needed extra passes.

One review found the vacuum cleared flour and sugar from wood in a single pass, supporting strong groove pickup on hard floors.

Low-pile carpet performance was generally good for surface debris and quick pickups.

Low-pile carpet pickup performed well in controlled tests, with reviewers reporting visible residue removed and low suction being enough in one demo.

Debris illumination was one of the most consistently praised features, with reviewers saying the green light makes hidden dust visible and cleaning more satisfying.

Debris illumination was praised for revealing floor messes and lighting under furniture; one demo also called the headlight bright.

Reviewers consistently liked the included heads and small tools, especially the Laser/Fluffy head, Motorbar, crevice tool, and Hair Screw/mini motorized tools for targeted cleaning.

The Pro bundle was praised for a broad accessory set, with multiple nozzles, extra rollers, batteries, chargers, and storage options highlighted as useful.

Medium/general carpet pickup was usually good to excellent on surface debris, though deeper carpet cleaning lagged larger models.

Medium-pile carpet pet-hair pickup impressed one reviewer, who reported clearing visible hair in several passes.

Edge and baseboard cleaning was mostly strong, with several reviewers noting good edge pickup or useful crevice/detail tools.

Edge cleaning was excellent in one controlled test, with dirt removed right to the skirting-board edge.

The dustbin was the most consistent complaint: reviewers repeatedly called it small, quick to fill, and sometimes inconvenient to empty.

The dust bin was one of the clearest weaknesses, with reviewers calling it small, quick to fill, and a major reason one long-term user stopped recommending the vacuum.

Filtration received high marks where tested, with sealed-system and HEPA-filter comments indicating strong dust containment.

Filtration and dust containment received strong marks, including HEPA praise and one retailer review describing dust as staying contained rather than returning to the air.

Floorhead design was mostly positive thanks to dedicated hard-floor and carpet heads, though one reviewer criticized the Laser Slim Fluffy casters.

Floorhead design drew both praise and criticism: reviewers liked its coverage and multi-surface tools, but some faulted the soft roller and hair-management limitations.

Review evidence supported scoring Battery and Charging for the Dyson V12 Detect Slim.

Battery and charging were mixed: dual batteries were valued, but short preferred-mode runtime and extra-battery dependence remained concerns.

Hard-floor fine-dust pickup was one of the V12's strongest areas, especially with laser illumination and the Fluffy head.

Fine-dust pickup on hard floors was excellent across lab tests, with flour, sugar, and fine crumbs cleared cleanly.

Build quality evidence was positive where discussed, emphasizing Dyson design, testing, and long-lived construction.

Build quality was one of the strongest points, with reviewers repeatedly describing premium materials, sturdy construction, and a solid, high-quality feel.

Smart and sensor features were broadly praised for auto suction and particle detection, though some reviewers found the particle counter more interesting than necessary.

Automatic floor sensing was viewed positively, especially for switching between carpet and hard floors without manual changes, though not every review focused on it.

Reviewers found suction and debris pickup strong for a lightweight cordless, especially on surface debris and hard floors, though not as powerful as larger Dyson models.

Reviewers repeatedly praised the HX2 Pro's suction, with several calling it exceptionally powerful or excellent, though one lab comparison found Dyson rivals stronger in raw suction.

Setup was praised as quick, easy, and supported by clear documentation or simple assembly.

One hands-on video found assembly quick and easy, with parts clicking together without trouble.

Clogging evidence was negative where tested, with one review saying the small bin clogs more often than competitors.

One lab review noted carpet fluff collecting and jamming to one side of the bin, suggesting some debris-flow weakness.

Hair pickup on hard floors was generally strong with the right head, though one review noted the Fluffy head struggled until switching to Motorbar.

Hard-floor hair pickup was strong in one pet-shelter test, where the reviewer said it had no problem with the hair.

Long-term evidence was positive in one extended review, which reported no loss of suction or functional issues after years of use.

One review tied value partly to expected longevity, saying the machine is built to last if looked after.

Design impressions were strongly positive, with reviewers calling the vacuum beautiful and praising its clean, futuristic lines.

One long-term user praised the floorhead for avoiding backward flicking of debris.

One hands-on reviewer liked that the brush motor shuts off on hard floors, framing it as a useful way to save power.

The floorhead seal impressed one reviewer for total coverage but disappointed another when hard-floor Cheerios lacked enough traction to pass under the head.

LED lighting was usually helpful for revealing debris, though at least one reviewer said it was weaker than Dyson's green laser.

Onboard and dock storage for tools was praised as convenient, especially for keeping common tools attached or nearby.

Packaging was praised in tested reviews for recyclable cardboard sections and little or no soft plastic.

Finish durability had a caveat from long-term use, with chipped handle paint after a year or two.

The floorhead's self-cleaning behavior impressed one reviewer, who said it cleared test flour from itself while vacuuming.

One demo described the agitator as helping the vacuum move on carpet, suggesting a mild self-propel feel.

Stair cleaning was viewed positively because the light body and Hair Screw tool make it easier to use away from floors.

One review found the brush bar could get stuck on carpet in Max mode, limiting stuck resistance on certain carpet conditions.

Small-space suitability was a clear strength, with reviewers recommending it for apartments and smaller homes.

One retailer review strongly praised warranty and support coverage, calling it among the best in the business.

One review liked that floor-type detection and roller behavior helped protect soft wooden flooring.

Tool and mode changes split reviewers: some found configuration changes easy, while others called parts stiff, roller swaps fiddly, or conversion a faff.

On long-pile wool carpet, one reviewer found the lowest power setting insufficient, implying only partial suitability.
