From vacuum to mop
Wet Cleaning Made Easy
The AquaTwister floorhead turns any Aqua model into a mop. It clicks on in place of the Electrobrush, and two counter-rotating pads fed by a removable 10 fl oz tank wash sealed floors — dried-on spills included. Vacuum with one head, mop with the other, both from the same machine instead of two appliances in the closet.
Three water levels plus Boost, selected right from the Mode Button on the display, which detects the AquaTwister automatically and switches from suction settings to water control.
360° Brilliant Light rings the floorhead so nothing gets missed along baseboards or under cabinets — exclusive to Miele.
Machine-washable pads rated to 140°F and tested for 100 hours of use, plus a 17 fl oz bottle of Miele FloorClean — roughly 25 cleanings.
One tank covers about 1,600 sq ft, and there's no dirty-water tank to empty, rinse or deodorize afterward.
Swap in seconds
Two Floorheads, One Machine
Switching between dry vacuuming and wet cleaning takes a click — no tools, no reassembly. The MultiFloor XXL Electrobrush handles carpet and hard floors with FloorDetect adjusting brush roll power on the fly; the AquaTwister takes over for sealed floors that need washing. Both mount to the same body, so the machine you already know changes jobs instead of changing places.
A drip tray is included so the wet head has somewhere to sit between uses.
Plus and Hardfloor models add a dedicated hard floor roller for wood and tile.
Full spec comparison
Every model, side by side
Every model below shows exactly what ships in its box. All six share the same motor, HEPA filtration, 0.5-quart bin, FloorDetect, Boost Mode and 3-in-1 body. What actually separates them is which floorheads and tools come in the box, and whether you get a second battery — so that's what this comparison focuses on.
Every model includes Lifetime HEPA filtration, the 3-in-1 Comfort/Reach/Compact design, and automatic FloorDetect — shown below is where they differ.

What's new in HX3
Built on what you love, boosted with what's next
Every model in the series shares the same German-engineered core — the Digital Efficiency Motor, Vortex Technology and Lifetime HEPA filtration — refined this generation with a longer-lasting battery, a clearer display and, on Aqua models, a wet floorhead that swaps on in seconds.
AquaTwister floorhead
Deep wet cleaning on sealed floors, on Aqua models — swaps on in place of the Electrobrush.
26% longer runtime
Up to 70 minutes per charge — up to 140 on two-battery models.
Intuitive digital display
Battery, cleaning mode and remaining runtime at a glance.
Boost Mode
An on-demand surge of extra power for stubborn, ground-in dirt.
Lifetime HEPA filtration
99.999% exhaust air filtration — and the filter never needs replacing.
Self-standing design
Stands upright on its own in Electrobrush mode — no wall mount needed mid-clean.
3-in-1 design
Comfort, Reach and Compact configurations adapt to every room and angle.
FloorDetect
Senses carpet versus hard floor and adjusts brush roll power automatically.
Hygienic emptying
A stainless-steel filter cage lets dust slide out with less contact and less mess.
0.5-quart bin & quick charging
Generous capacity so you empty less often, with a fast-charging Li-Ion battery.
70 min
Runtime on one battery in Low mode — 26% longer than the HX2
140 min
Runtime on the two-battery Plus and Plus Aqua
Three
Power modes — Low, Eco and High, plus three water levels on Aqua models
Boost
On-demand power burst for ground-in dirt, counted down on the display
Stress-free vacuuming
Lasting Power & Convenience
This generation runs 26% longer than the one before it — up to 70 minutes on a charge, or up to 140 on the two-battery Plus models. Choose Low, Eco or High to match the job, and the intuitive display keeps you informed: battery life, cleaning mode, the Boost timer and the runtime you have left at your current setting.
Boost Mode delivers an on-demand surge of extra suction for ground-in dirt, with a timer on the display so you know where you stand.
Replaceable Li-Ion batteries charge quickly and can be swapped, so a second battery doubles your session rather than pausing it.
Powerful performance
Strong Pick-Up on Every Surface
The cordless Triflex HX3 cleans as powerfully as a conventional Miele canister, and it deep cleans carpet rather than just skimming it. The Digital Efficiency Motor works with Vortex Technology to capture 99.99% of dust, and the Lifetime HEPA filter then holds 99.999% of what passes through it, so the air coming out is cleaner than the air going in — a real difference if anyone in the house has allergies.
The HEPA filter never needs replacing — no recurring filter cost for the life of the machine.
Hygienic emptying via a stainless-steel filter cage, so dust slides out of the 0.5-quart bin instead of clinging to it.
74 dB(A) across the series — quiet enough for a normal conversation nearby.

Designed around the room
Ready the Moment You Are
The Triflex stands upright on its own in Electrobrush mode, so answering the door mid-clean doesn't mean hunting for somewhere to lean it. The 3-in-1 body then reconfigures for whatever you're cleaning: Comfort for open floors, Reach for ceilings and high corners, Compact for stairs, upholstery and the car.
Aqua models don't self-stand with the AquaTwister attached — click the Electrobrush back on to stand it upright.
A wall mount and charger are included with every model in the series.
Good to know
Questions we get asked
Still not sure? Chat with a Vacuum Geek now.
Does the Aqua vacuum and mop at the same time?
No, and it's worth being clear about that. The Aqua does both jobs, but with two different floorheads. The MultiFloor XXL Electrobrush does the dry vacuuming; the AquaTwister washes sealed floors. Swapping between them takes seconds and no tools, and the display switches from suction levels to water levels on its own once it detects the wet head. So the routine is vacuum, then mop — one machine doing both, rather than one pass doing both.
Is it safe on hardwood floors?
On sealed hardwood, yes — with the caveat that Miele recommends the driest setting. Standing water damages wood over time regardless of the machine putting it there. The AquaTwister is designed for water-resistant flooring: tile, vinyl, laminate, sealed stone and sealed hardwood. On unsealed or waxed wood, stick to the Electrobrush.
Can I add wet cleaning to a non-Aqua model later?
Yes — the AquaTwister floorhead (HX-AT 10) is sold separately for $249 and fits every Triflex HX3. That said, the Aqua costs only $200 more than the standard HX3 and includes the floorhead plus pads, solution and tray. If you already know you want mopping, buy the Aqua.
How long do the pads last, and how do I clean them?
They go in the washing machine at up to 140°F and are tested for 100 hours of use each. A four-pack of replacements (HX-APU) is on our site. Rinse them after a particularly dirty job rather than letting them dry caked — same as any mop head.
Is there a dirty water tank to empty?
No. The AquaTwister uses a clean-water tank and washable pads rather than recovering dirty water, so there's no second tank to rinse out and nothing sitting wet between uses developing an odor. The trade-off is that the pads do the holding, which is why you wash them.
How good is it on carpet?
Genuinely good — this is where the Triflex separates itself from most cordless sticks. The Digital Efficiency Motor pulls like a corded canister, and FloorDetect raises brush roll power automatically when it senses carpet. For deep pile or heavy pet traffic, the CarpetCare roller brush (HX-CCT20) is worth adding.
Do I need the two-battery Plus models?
Depends on square footage. One battery gives up to 70 minutes in the lowest power mode — realistically less in Eco or High. If you clean a whole house in one session, or you have a lot of carpet running at higher power, the second battery is what keeps you from stopping to charge. Under about 1,500 sq ft, one is usually plenty.
Does the filter ever need replacing?
The HEPA Lifetime filter is designed to last the life of the machine — no recurring filter cost, which is unusual in this category. Tap it out over the trash periodically and rinse per the manual. A replacement finedust filter (HX-FSF2) is available if one ever gets damaged.
Will my HX1 or HX2 accessories still fit?
Most of them. Miele kept the battery, charger, finedust filter, hardfloor care tool and accessory holder compatible across the HX1, HX2 and HX3.
Which model do you recommend for most homes?
For a mix of hard floors and carpet with no pets, the standard HX3 does the job. The Aqua is the one we point most people toward if they have tile, vinyl or sealed hardwood — having the mop built into the vacuum genuinely changes how often you bother. Go Plus or Plus Aqua only if your square footage outruns one battery.
Already own a Triflex?
Upgrading from an HX1 or HX2
The HX3 replaces the HX2 line, which Miele is phasing out over the coming months — HX2 models are still available while stock lasts. Miele kept the accessory platform intact across generations. Batteries, filters, the hardfloor care tool, the accessory holder and the charger all fit the HX1, HX2 and HX3 — so the spares in your closet aren't wasted, and a second battery bought today still works if you upgrade later.
Which HX3 replaces your model
The Aqua and Plus Aqua are new to the series — there's no HX2 equivalent, because the AquaTwister floorhead didn't exist until this generation.
