The Miele Duoflex HX1 (SQLL0, MPN 12556610) is Miele’s everyday cordless stick vacuum — a 2-in-1 machine that converts between stick and handheld configuration in seconds, weighs just 7 lbs (3.1 kg), delivers up to 55 minutes of runtime on a single charge, and captures 99.99% of dust per IEC 62885-4 through its Hygiene filter. The Digital Efficiency Motor and MultiFloor electrobrush with automatic floor recognition provide powerful suction across hard floors, low-pile carpet, and area rugs. Miele’s performance testing compares its cleaning output favorably to a corded Miele Complete C3 canister with TurboBrush per IEC 62885-2. Available in Nordic Blue. Priced at $649.00. Rated 4.5 stars from 211 Miele USA reviews — the most-reviewed Miele cordless vacuum on the Miele USA website.

2-in-1 Design — Stick and Handheld in One Machine
The Duoflex HX1 converts between two configurations instantly — no tools required:
Stick Mode — full-length stick vacuum for floor cleaning. The PowerUnit sits at the top of the wand with the handle below. Comfortable for whole-room floor cleaning sessions on hard floors and carpet.
Handheld Mode — wand removed, PowerUnit used solo as a compact handheld vacuum for stairs, upholstery, car interiors, above-floor surfaces, and quick spot cleaning anywhere in the home.
The Duoflex design is simpler and more intuitive than the Triflex HX1’s 3-in-1 system — two clearly defined modes rather than three. Customers report particularly liking the grab-and-go convenience for quick daily cleaning, with one UK customer noting: “The ease of getting around beds without a cord is great. The suction power is amazing and it’s very easy to empty and clean.”
Key Features of the Miele Duoflex HX1
Digital Efficiency Motor — Powerful, Lightweight, Long-Lasting
The Digital Efficiency Motor is purpose-built for cordless vacuum use — optimized for high suction output per watt of battery draw, maximizing both power and runtime from the 25.2V Li-Ion battery. Miele’s independent testing per IEC 62885-2 benchmarks the Duoflex against a Miele Complete C3 canister with TurboBrush on carpet and hard floor tasks.
The included MultiFloor electrobrush uses automatic floor recognition to detect carpet versus hard floor and adjusts the brushroll speed accordingly — no manual switching needed when moving between floor types. The brushroll agitates carpet fibers to remove embedded dirt and hair that suction alone cannot dislodge. Note that the Duoflex’s standard-width MultiFloor brush is narrower than the Multi Floor XXL SEB 430 included with the Triflex HX1 — the Triflex covers more width per pass.
The Hygiene filter captures 99.99% of fine dust per IEC 62885-4. Unlike the Triflex HX1’s lifetime filter (never replaced), the Duoflex’s Hygiene filter is replaceable — the optional Duoflex Fine Dust Filter HX-FDF 20 ($44.99) is the correct replacement and provides even finer particle capture. ComfortClean technology automatically self-cleans the filter during operation to maintain filtration efficiency between replacements.
55-Minute Runtime — Exchangeable Battery
Up to 55 minutes of runtime on power level 1 without the electrobrush connected. The 25.2V Li-Ion 2500 mAh battery is exchangeable — though note that unlike the Triflex, Miele does not currently list a standalone spare battery purchase option specifically for the Duoflex. Runtime with the electrobrush connected is not separately specified by Miele for this model.
Honest buyer note: One verified Miele reviewer specifically flags that actual runtime on their unit fell noticeably short of 55 minutes at power level 1. Real-world runtime will vary based on floor type, suction level, and how often the electrobrush is engaged. Budget for approximately 30–40 minutes of typical mixed-use runtime with the electrobrush.
Vortex Technology — Consistent Suction
Vortex Technology optimizes airflow through the 0.3-liter dust container to maintain suction as the container fills. Note the Duoflex’s 0.3-liter container is smaller than the Triflex’s 0.5 liters — in a large home with pet hair or heavy debris, you may need to empty it more frequently during a single cleaning session.
2-Level Suction Control
Two suction levels selected via buttons on the handle — eco (power level 1 for maximum runtime) and boost (power level 2 for maximum suction). Simpler than the Triflex’s 3-level slide control, which suits many users who prefer a straightforward low/high choice over a graduated selector.
Button-Press Dust Container Emptying
The 0.3-liter dust container empties at the press of a button — no twisting required, unlike the Triflex’s Twist2Open system. Hygienic emptying directly into the bin without hand contact with collected debris.
7 Pounds — The Lightest Miele Cordless
At 7 lbs (3.1 kg), the Duoflex is one pound lighter than the Triflex HX1 at 8 lbs. That difference is most felt when using it in handheld mode for above-floor cleaning, carrying it up stairs, or during extended cleaning sessions. Multiple reviewers specifically call out the weight as a strong point.
Standard Wall Bracket — Storage Without Charging
The included standard wall bracket stores the Duoflex vertically on the wall — but does not charge the battery. To recharge, remove the vacuum and connect the power supply unit directly to the machine. Recharge time is 210 minutes (3.5 hours) from empty — 30 minutes faster than the Triflex’s 240-minute charge time. The Triflex HX1’s wall-mount charging station keeps the battery topped up continuously; the Duoflex requires deliberate plugging in to recharge.
79 dB — Quiet Operation
At 79 dB, one decibel quieter than the Triflex HX1 at 80 dB — a minor difference in practice.
Accessory Storage HX-AH 20
The included HX-AH 20 accessory holder mounts alongside the wall bracket to store the dust brush, upholstery nozzle, and crevice nozzle — accessories always within reach.
What Miele Customers Are Saying About the Duoflex HX1
The Duoflex HX1 holds 4.5 stars from 211 Miele USA reviews — the highest review count of any Miele cordless vacuum on the Miele USA website. Selected verified customer feedback:
“The ease of getting around beds without a cord is great. The suction power is amazing and it’s very easy to empty and clean.” — Pip, April 2026
“Excellent product, powerful suction. I will never buy anything but Miele in future.” — Anonymous purchaser, April 2026
“Best hand held vacuum that I have had, really effective at picking up on all surfaces and the charge lasts. My only criticism is that the dust container is small and needs emptying on a regular basis.” — Gaynor, April 2026
The small dust container (0.3L) is the most consistent criticism across reviews — noted by multiple owners in larger homes or with pets. For larger homes or households with pets that shed heavily, the Triflex HX1’s larger 0.5-liter container will interrupt cleaning sessions less often.

What is the difference between the Duoflex HX1 and the Triflex HX1 Facelift?
The Duoflex HX1 ($649) is a 2-in-1 cordless — it converts between stick and handheld only. The Triflex HX1 Facelift ($699) offers three configurations (Reach, Comfort, Compact). The Triflex also has a larger 0.5-liter dust container (vs 0.3L on the Duoflex), the wider Multi Floor XXL SEB 430 electrobrush, a Hygiene lifetime filter (never replaced, vs the Duoflex’s replaceable Hygiene filter), 3-level suction control (vs 2-level), 60-minute solo runtime (vs 55 minutes), and an included wall-mount charging station (vs the Duoflex’s standard wall bracket that does not charge). The Duoflex is lighter at 7 lbs (vs 8 lbs) and charges faster at 210 minutes (vs 240 minutes). For $50 more, the Triflex offers meaningful upgrades in capacity, versatility, and convenience.
Does the wall bracket charge the Duoflex battery?
No — the included standard wall bracket is for storage only. To charge the battery, remove the vacuum from the bracket and connect the power supply unit directly to the machine. This is different from the Triflex HX1’s wall-mount charging station, which keeps the battery topped up while the vacuum is stored on the wall.
Does the Duoflex HX1 need replacement filters?
Yes — unlike the Triflex HX1 Facelift which has a lifetime filter, the Duoflex’s Hygiene filter is designed to be replaced periodically. The correct replacement is the Duoflex Fine Dust Filter HX-FDF 20 ($44.99). The ComfortClean system helps extend filter life between replacements by self-cleaning during operation.
What is the actual runtime with the electrobrush?
Miele specifies 55 minutes for the solo PowerUnit at level 1 without the electrobrush. Runtime with the electrobrush connected is not separately published for the Duoflex by Miele — budget for approximately 25–35 minutes of typical use with the electrobrush engaged at mixed power levels. One reviewer notes actual runtime falls short of the advertised 55-minute figure in real-world conditions.
Is the Duoflex HX1 good for pet hair?
The MultiFloor electrobrush handles surface pet hair on low to medium pile carpet and area rugs effectively. For heavy shedding pets on high-pile carpet throughout a large home, note that the 0.3-liter container will fill quickly with pet hair and need frequent emptying. For significant pet hair volume, the Triflex HX1’s larger 0.5-liter container will interrupt cleaning sessions less often.
