Features That Make Everyday Cleaning Easier

Gentle on the floors you worry about

The soft roller of the Hardfloor Care Tool glides over hardwood and tile and lifts fine dust without the scuffing risk of a stiff brush.

You can see what you are cleaning

BrilliantLight LEDs on the electrobrush throw light across the floor ahead of you, so dust and crumbs on shiny hard floors are easy to spot.

It adjusts so you don't have to

FloorDetect senses whether you are on carpet or a hard floor and changes suction as you cross the room, so rugs get the power they need without you stopping to press anything.

Three shapes for three jobs

The patented 3-in-1 design reconfigures in seconds: Comfort for open floors, Reach for getting under furniture, and Compact as a handheld for stairs, upholstery and the car.

Park it anywhere, mid-clean

The Triflex stands up on its own without a wall bracket, so you can set it down to move a chair or answer the door and pick up where you left off.

Good to know

If you also want to mop your hard floors, look at the Triflex HX3 Plus Aqua, which pairs this soft roller with the AquaTwister wet-cleaning attachment and a second battery. If you have a larger home and only need dry cleaning, the Triflex HX3 Plus adds a second battery to everything in this box.

FAQ's

What does the Hardfloor Care Tool do?

It is a soft roller floorhead designed for hard floors. It picks up fine dust and larger debris in one pass and is gentle on delicate surfaces such as hardwood. The MultiFloor XXL electrobrush is still in the box for carpets and rugs.

How long does the battery last on a single charge?

Miele rates the PowerUnit at up to 70 minutes on its own at the lowest setting. With the MultiFloor XXL electrobrush attached, expect 38 minutes on the low setting and 15 minutes on high. The 25.2V lithium-ion battery is removable and takes 240 minutes, about 4 hours, to fully recharge.

Can the Triflex HX3 Hardfloor mop?

Not out of the box; it is a dry vacuum. The AquaTwister HX-AT 10 wet-cleaning attachment is sold separately and fits every Triflex HX3. If you know you want wet cleaning, the Triflex HX3 Plus Aqua includes both the AquaTwister and this soft roller.

Is it good for allergy sufferers?

Yes. It picks up over 99.99% of dust, and its HEPA lifetime filter provides 99.999% exhaust air filtration under EN 1822-1:2019, so fine particles stay in the machine instead of blowing back into the room.

How is it different from the Triflex HX3 Plus?

The Plus includes the same floorheads and tools plus a second battery, doubling the runtime to up to 140 minutes. If one battery covers your home, the Hardfloor is the better value.

Does it stand up on its own?

Yes. The Triflex parks free-standing without a wall bracket, so you can set it down mid-clean. A wall mount is also included in the box if you would rather store it mounted.

Three machines in one

What the Triflex HX3 does

This is the Triflex the line is built on. Same motor, same HEPA Lifetime Filter and the same 3-in-1 body as every other HX3 — the straightforward kit, without the extra floorheads. If you want Miele suction in a cordless stick and nothing in the box you won't use, this is the one.

Three ways to hold it

One machine for floors, ceilings and the car

The motor unit unclips and moves. Down at the bottom in Comfort mode the weight sits near the floor, which is where you want it for everyday vacuuming. Up at the top in Reach mode the wand goes under the bed, behind the couch and into ceiling corners without you holding the heavy end overhead. Pull the wand off altogether and the motor unit is a handheld for stairs, upholstery and the inside of the car.

  • Comfort mode keeps the weight down at floor level
  • Reach mode moves the motor to the top for under and above furniture
  • Handheld mode with dusting brush, XL upholstery nozzle and crevice tool
  • Stands up on its own between rooms, so no wall bracket is needed

Dry vacuuming

Miele suction, and a filter you never replace

The MultiFloor XXL electrobrush reads the floor underneath it. FloorDetect steps the brush roller up when you move onto carpet and eases it off on hard floors, so you are not stopping to change a setting every time the flooring changes. And what the vacuum picks up stays inside it: the HEPA Lifetime Filter holds 99.999% of exhaust particles and is not sold as a replacement part, because it does not need to be.

  • MultiFloor XXL SEB 431 electrobrush
  • FloorDetect adjusts between carpet and hard floors on its own
  • HEPA Lifetime Filter, 99.999% exhaust filtration, nothing to buy again
  • 0.5-quart bin releases and empties without putting your hand in the dust
Everything included with the Miele Triflex HX3 in Brilliant White.
In the box

Everything you need, nothing you don't

A wall bracket and charger, the accessory holder, and the three hand tools that cover the rest of the house. The Triflex also parks upright on its own, so if you would rather not drill into a wall, you don't have to.

  • MultiFloor XXL electrobrush
  • Dusting brush, XL upholstery nozzle and crevice nozzle
  • Accessory holder HX-AH, wall mount and charger
  • Parks upright on its own — wall mounting is optional

Runtime is Miele's rating for the motor unit at the lowest power setting. With the powered floorhead attached, expect 38 minutes on low and 15 on high.

Full spec comparison

Every model, side by side

All six Triflex HX3 models share the same motor, HEPA lifetime filtration, 0.5-quart bin, FloorDetect, Boost Mode and 3-in-1 body. What separates them is which floorheads and tools come in the box, and whether you get a second battery.
