Features That Make Everyday Cleaning Easier

Finish the whole house in one session

When the first battery runs down, swap in the second and keep going. No stopping halfway through to wait on a charger.

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 under furniture and along baseboards is 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 you are not 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.

FAQ's

How long does it run with both batteries?

Miele rates each battery at up to 70 minutes with the PowerUnit on its own at the lowest setting, so up to 140 minutes across both. With the MultiFloor XXL electrobrush attached, expect 38 minutes per battery on low and 15 minutes on high. Each battery takes 240 minutes, about 4 hours, to fully recharge.

Do I need the two-battery Plus?

It depends on how much you clean in one session. One battery covers roughly 1,720 sq ft per charge at Miele's rating, and real-world runtime drops on higher power settings or thick carpet. If you like to do the whole house in one go, the second battery means swapping instead of waiting for a recharge.

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.

I have a Triflex HX2 Pro. Is this the replacement?

Yes. The HX3 Plus replaces the HX2 Pro. Batteries, the charger, the fine dust filter, the Hardfloor Care Tool and the accessory holder from the HX1 and HX2 all fit the HX3.

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.

Can the Triflex HX3 Plus 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, or the Triflex HX3 Plus Aqua includes it along with everything in this box.

Wet and dry, one Miele

What the Triflex HX3 Aqua does

The Aqua is the Triflex that cleans hard floors wet as well as dry. It vacuums like every other HX3 — same motor, same HEPA Lifetime Filter, same 3-in-1 body — and then the AquaTwister floorhead goes on and it mops. Here is what that looks like day to day.

Wet cleaning

Mop your hard floors with the AquaTwister

Take the electrobrush off, click the AquaTwister on, and the same machine mops. Two microfiber AquaPads spin against the floor while the tank feeds them water and Miele FloorClean solution, so dried-on spills get lifted instead of pushed around. Three water levels plus a Boost setting let you go light on sealed wood and heavy on tile and stone.

  • Two rotating AquaPads, washable and reusable
  • Three water levels plus Boost for stubborn spots
  • 17 fl oz of Miele FloorClean concentrate in the box
  • Storage tray included, so the wet head has somewhere to sit

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 SEB 436 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. BrilliantLight across the front of the head shows you the dust you would otherwise walk past. 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 436 electrobrush with BrilliantLight
  • FloorDetect adjusts between carpet and hard floors on its own
  • HEPA Lifetime Filter, 99.999% exhaust filtration, nothing to buy again
  • Bin releases and empties without putting your hand in the dust

Runtimes are Miele's ratings 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.
