FAQ's
What the Triflex HX3 Plus does
The Plus is the HX3 for a house you can't finish on one charge. Two lithium-ion batteries ship in the box, so one is on the charger while the other is on the vacuum, and the Hardfloor Care Tool comes with it for sealed wood and tile.
Swap in seconds and keep going
The battery is a click-out pack, not a sealed cell. When the first one runs down you drop in the second and carry on — no waiting, no half-cleaned house. Between the two you get up to 140 minutes at the lowest setting, roughly 3,440 square feet, which covers most homes in a single session with the other pack charging for next time.
- Two lithium-ion batteries in the box
- Tool-free swap, no waiting on a charge
- Up to 140 minutes combined at the lowest setting
- Hardfloor Care Tool soft roller included as well
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
Miele suction, and a filter you never replace
The MultiFloor XXL SEB 436 electrobrush reads the floor underneath it, and BrilliantLight across the front of the head shows you the dust you would otherwise walk past. 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 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
- 0.5-quart bin releases and empties without putting your hand in the dust
Runtimes are Miele's ratings across both batteries at the lowest power setting. With the powered floorhead attached, expect 76 minutes on low and 30 on high.
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.
