Pros

• Hard Floor — Fine Dust Pickup 4.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.8

• Support & Reliability 4.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.8
  Support is bolstered by mention of an extensive warranty in one review and positive signals like proactively correcting documentation. While not all sources discuss service, overall confidence in Miele reliability is high.
• Upholstery / Above-Floor Pickup 4.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.7
  Upholstery and above-floor cleaning are standout areas, especially with the motorized Electro Compact brush that reviewers say lifts embedded pet hair from sofas, pet beds, and car seats. Dusting tools also help with delicate items like shutters, keyboards, and cornicing.
• Hair Pickup — Hard Floors 4.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.7
  Hair pickup on hard floors is repeatedly described as excellent, with hair being pulled in from an inch or two away in some tests. It performs especially well for visible pet hair and dander on smooth surfaces.
• Ease of use 4.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.7
  Ease-of-use is widely praised thanks to simple controls, a comfortable grip, quick configuration changes, and light handling that reduces arm fatigue. Small annoyances include occasional tight tool fit and the need to plug the charger into a small port rather than true dock-and-charge for some setups.
• Overall durability/longevity 4.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.7
  Several reviewers expect strong longevity thanks to the solid construction and brand reputation, and one source highlights a long warranty structure. The main durability unknowns are typical wear items like the brushroll and battery over time.
• Stair Cleaning 4.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.7
  Stair cleaning is frequently called out as easier in handheld mode using the motorized mini brush, with reviewers reporting quick, thorough pickup of hair and debris on steps. This is one of the practical benefits of the convertible design.
• Build quality & durability 4.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.7
  Build quality gets high marks: reviewers describe it as sturdy, robust, and not plasticky, with parts that click together cleanly. The overall feel is repeatedly framed as high-end compared with many cordless sticks.
• Suction & Airflow 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.6
  Cleaning performance is a standout: reviewers report powerful suction and fast pickup on hard floors, rugs, carpets, and upholstery, with automatic power changes that react quickly. A few note that very large debris can scatter or require extra passes/placement.
• Noise level 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.6
  Noise is often described as relatively quiet for a cordless stick, with one review measuring around mid-60 dB in normal use and higher readings closer to the high-70s on max. Overall, it trends quieter than many competing cordless vacuums in comparable power.
• Under-Furniture Pickup 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.6
  Reviewers report it can tuck well under cabinets, furniture, and plinths thanks to the flat, hinging head, helping pull out hidden dust bunnies. This is repeatedly highlighted as a real-world convenience for whole-room touch-ups.
• Hair Pickup — Carpets 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.6
  Hair pickup on carpets is a strength, with reviewers reporting near-complete removal of visible hair on many carpets and rugs. Some edge hairs and very fine hairs on tough matting can remain, but overall results are top-tier.
• Versatility 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 4.6
  The Duoflex is repeatedly used as a multi-tasker: floors, rugs, upholstery, stairs, car interiors, cobwebs, and even blinds/keyboards with the dusting tools. The multi-surface head reduces the need to swap floorheads, boosting day-to-day versatility.
• Low-profile design 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.6
  The floorhead is described as notably low and able to lie flat (about 2.5 inches mentioned), which helps reach under furniture and into tighter spaces. Low profile is one of the practical design advantages called out across reviews.
• Maneuverability & Handling 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.6
  Handling is a strong point: reviewers describe it as comfortable, well-balanced, and easy to steer around obstacles, with less arm ache than many cordless models. Overhead handheld use can still feel noticeable for some, but overall maneuverability is rated highly.
• Pet-Ready Features 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.6
  Multiple reviews frame this as a pet-focused stick: strong hair and dander pickup plus a motorized mini brush for upholstery and pet beds. The main pet-related drawback is hair wrapping on the main brushroll and the small bin filling quickly in furry homes.
• Convertible handheld design 4.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.5
  Reviewers like how quickly it converts into a handheld for couches, cars, stairs, and above-floor work, with the locking system making the switch feel seamless. This flexibility is a recurring reason it is used for frequent quick cleanups.
• Tool-change simplicity 4.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.5
  The SpeedLock/locking system earns frequent praise for making nozzle swaps and stick-to-handheld conversion fast and low-fuss. A couple of comments mention fit can be a bit tight at times, but overall it is viewed as a major usability win.
• Aesthetic design & finish 4.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.5
  Design is consistently praised as sleek and premium, with textured finishes and multiple color options that look good on display. Fit and finish are positioned as a Miele hallmark across sources.
• Area Rug Handling 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.4
  On rugs, reviewers note the head senses resistance and ramps up (often strongly enough to tug lighter rugs), improving agitation and pickup. Rug transitions and auto-adjust behavior are generally described as quick and effective.
• Carpet — Low-Pile Pickup 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.4
  Low-pile carpets and flatter rugs are cleaned very effectively, often in one pass for dust and hair, with boost rarely required. Larger pieces may take additional passes depending on how easily they scatter.
• Carpet — Medium-Pile Pickup 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.4
  Medium-pile carpet performance is consistently strong, including good pet-hair removal and fast clearing of fine debris. A few stubborn situations (like high-friction entry matting) can still hold onto smaller hairs.
• Packaging quality 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.4
  Packaging is often described as neat and protective, with some appreciation for reduced excessive plastics and recyclable cardboard. A few still observed some plastic components or double-boxing depending on region/model.
• Suitability for small spaces 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.4
  It is most compelling for apartments, smaller homes, or as a secondary vacuum for frequent maintenance cleans. Larger homes may find the combination of bin size, potential hair-wrap, and runtime limits makes it less ideal as the only vacuum.
• Accessories & Tools 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.4
  Attachment bundles vary by model, but reviewers consistently praise the useful core tools (crevice, dusting, upholstery) and especially the motorized Electro Compact brush for pet hair on furniture and stairs. Minor gripes include wanting a specialty/jointed reach tool or better dock storage for larger tools.
• Overall opinion 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.4
  Across sources, sentiment is strongly positive: reviewers repeatedly call the Duoflex HX1 one of the better-performing cordless sticks they have used, especially for pet homes. The recurring reservations are a small 0.3L bin, mixed real-world runtime on floors, and brushroll hair-wrap.
• Edge & Baseboard Cleaning (Hard Floors) 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.4
  Edge and corner performance is generally strong, with reviewers noting it can reach right up to skirting boards and into corners where hair collects. Some testing still left a few hairs at edges, but overall edge cleaning is above average.
• Cordless convenience 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.3
  As a cordless stick, it is widely used for quick daily pickups and grab-and-go cleaning, especially when stored on a wall bracket. The convenience is tempered by shorter real-world runtime for some users and the small bin requiring frequent stops.
• Assembly and Setup 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 4.3
  Unboxing and setup are generally described as straightforward, with printed guides and a standard wall-mount bracket installation. Some packaging/documentation quirks were noted, but assembly is not viewed as complicated.
• Floorhead design 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.3
  The multi-surface electrobrush is praised for quick transitions and auto adjustment of suction/brush speed across floor types, plus good swivel/hinge behavior. Downsides noted include occasional pinging/scattering of larger debris and limited ability to fully avoid that with brush control.
• Maintenance requirements 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.3
  Routine maintenance is generally viewed as easy thanks to twist/ComfortClean-style filter cleaning and included brushes for clearing pre-filters. The main ongoing work is detangling the brushroll and emptying the small bin more often, especially in pet homes.
• Weight 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.3
  At roughly 6.8–6.83lb (about 3.1kg), it is commonly described as lightweight for a cordless stick, helping with quick sessions and above-floor work. Some still find the weight noticeable when held overhead in handheld mode.
• Filtration / Dust Containment 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.3
  Filtration is described as a two-stage system with claims of up to 99.99% fine-dust retention; one review notes it is not officially HEPA-certified. Built-in filter-cleaning mechanisms reduce the need for washing and help maintain airflow over time.
• Controls & UI 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.3
  Controls are intentionally simple: generally a power button plus a boost/high button, paired with a basic battery indicator. Reviewers like the straightforward operation but note the lack of a screen or more detailed status/controls compared with some rivals.
• Onboard tool storage 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.3
  Onboard storage is helpful for keeping a couple of frequently used tools clipped to the vacuum, reducing trips back to a closet. Some note that larger motorized tools may not fit the holder and wish the wall dock offered more integrated accessory storage.
• Surface safety with attachments 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.2
  Attachments like soft dusting brushes and rubberized tool tips are praised for being gentle on delicate surfaces and trim. One review heard a mild scratching sound on hard floors (likely wheels), so caution is advised on very sensitive hardwood finishes.
• Comparative performance 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.2
  Comparisons often place it near Dyson on core cleaning results, with some reviewers preferring Miele’s easier filter maintenance and premium feel. Tradeoffs versus key rivals include less tech (like illumination), brushroll tangling, and a smaller bin.
• Carpet — High-Pile Pickup 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.1
  High-pile and plush carpets are handled well for a cordless stick, though reviewers sometimes needed extra runs and noted that runtime can drop faster as the vacuum increases power on thicker carpet. Pickup remains strong, but session length can become the limiter.
• Cyclone performance 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.1
  Several sources reference Miele Vortex/cyclonic design and describe an airflow path intended to keep performance strong, with reports of strong pickup and little dust sticking in the bin. Most detail is descriptive rather than lab-measured, but user impressions are positive.
• Emptying & Mess Control 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.1
  Emptying is usually quick via a release door and is often described as largely hands-free, but frequent emptying is common due to the small bin. If overfilled, hair can snag around the pre-filter and may require manual clearing.
• Battery & Charging 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 3.9
  Charging is typically around 3.5 hours, with wall-mount storage available; some reviewers wish for a true dock-and-charge behavior rather than plugging into a small port. A key limitation repeated across sources is that the battery is not swappable.
• Price & Value 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 3.8
  Value perceptions hinge on priorities: many say performance and premium build justify the price, while others feel the feature set (small bin, no swappable battery, sometimes no lights) is limited for the cost versus Dyson/Shark alternatives.
• Runtime (Measured, Default) 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 3.7
  Real-world floor cleaning commonly lands around 20–30 minutes on mixed surfaces for some testers, while low-power handheld use can approach the advertised longer figures. Auto adjustments on carpet can shorten runtime compared with hard-floor cleaning.
• Hard Floor — Large Debris Intake 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 3.6
  Large-debris pickup is mixed: some reviewers found cereal/lentils can scatter on hard floors and require repositioning or extra passes, while others report solid pickup of everyday chunks and dried mud. Performance seems most consistent once debris is directly under the intake.
