Description
Miele Triflex HX3 Aqua Cordless Vacuum & Floor Washer – Obsidian Black
Don't just vacuum your floors, then take hard-floor cleaning to the next level with the Miele Triflex HX3 Aqua.
Combining the powerful cordless cleaning performance of Miele's Triflex HX3 with the innovative AquaTwister wet-cleaning system, the HX3 Aqua gives you one versatile machine for everyday vacuuming and washing bare floors.
Powered by Miele's Digital Efficiency Motor and Vortex Technology, the Triflex HX3 Aqua delivers exceptional dust pickup across hard floors, area rugs and carpeting. When it's time to wash your hard floors, simply switch to the AquaTwister attachment with its rotating cleaning pads, adjustable water dispensing and integrated 360° lighting.
It's an ideal solution for busy households here in Canada looking to reduce the number of cleaning appliances they need while still enjoying the flexibility and performance of a premium Miele cordless vacuum.
Introducing the Miele AquaTwister Attachment
The feature that sets this model apart is Miele's AquaTwister wet-cleaning attachment.
Rather than simply dragging a damp pad across your floor, the AquaTwister uses powered rotating cleaning pads to actively scrub the surface and help remove everyday dirt, footprints and stubborn dried-on messes.
Water delivery can be adjusted depending on the flooring and cleaning task, giving you greater control over how much moisture is applied.
It's ideal for cleaning water-resistant hard floors including:
- Sealed hardwood
- Tile
- Luxury vinyl
- Laminate suitable for damp cleaning
- Stone
- Other water-resistant smooth flooring
For homes with large amounts of hard flooring, the AquaTwister transforms the HX3 from simply a vacuum into a much more complete floor-care system.
360° SpotLight Reveals the Dirt
Cleaning is easier when you can actually see what you're trying to remove.
The AquaTwister features an integrated 360° SpotLight, illuminating the floor around the cleaning head and helping expose dirt and marks—even around furniture and in harder-to-see areas.
Combined with the rotating cleaning pads, it helps you identify and tackle areas that might otherwise be missed.
Powerful MultiFloor XXL Vacuuming
When you're not washing your floors, the HX3 Aqua functions as a premium Miele cordless vacuum.
The included MultiFloor XXL SEB 436 electric floorhead provides powerful cleaning across hard flooring, rugs and carpeting.
Miele's FloorDetect technology automatically recognizes the flooring beneath the vacuum and adjusts performance accordingly, helping you move throughout your home without constantly changing settings.
BrilliantLight LED Floor Illumination
The MultiFloor XXL electric floorhead also features Miele's BrilliantLight LED illumination.
The bright light across the front of the floorhead exposes fine dust, crumbs, pet hair and debris that can be difficult to see under furniture or on darker flooring.
It's especially useful for spotting the fine dust that often disappears under normal room lighting.
Miele's Versatile 3-in-1 Design
The Triflex HX3 isn't restricted to one configuration.
Miele's patented 3-in-1 design allows the position of the PowerUnit to be changed depending on how and where you want to clean.
Comfort Mode positions the motor and battery closer to the floor, creating a balanced vacuum thats comfortable for everyday floor cleaning. The vacuum can also stand upright on its own when you need to pause.
Reach Mode positions the PowerUnit at the top of the vacuum, giving you greater flexibility for reaching underneath furniture and cleaning ceilings, mouldings and other elevated areas.
Compact Mode converts the HX3 into a powerful handheld vacuum for stairs, furniture, vehicles and quick cleanups.
One machine adapts to virtually every cleaning task around your home.
Up to 70 Minutes of Cordless Cleaning
The Miele Triflex HX3 Aqua is powered by a high-performance 25.2V VARTA lithium-ion battery.
Depending on the configuration and power level selected, you can achieve up to:
- 70 minutes using the PowerUnit on its own
- 38 minutes when using powered accessories on the lower setting
- 15 minutes when using powered accessories on the highest setting
- Up to approximately 160 m² of cleaning area
The battery is removable and replaceable, helping make the HX3 a cordless vacuum designed for long-term ownership.
Miele's Digital Efficiency Motor
At the heart of the Triflex HX3 Aqua is Miele's Digital Efficiency Motor.
Combined with Miele's advanced Vortex Technology, the HX3 provides 99.99% dust pickup, delivering the strong cleaning performance you'd expect from a premium Miele vacuum.
Whether you're tackling fine dust on hardwood or embedded debris in carpeting, the HX3 is designed to provide powerful cleaning performance without being tied to an electrical outlet.
FloorDetect Automatic Floor Recognition
Move seamlessly between different flooring surfaces with FloorDetect technology.
The HX3 automatically detects the type of floor beneath the MultiFloor XXL electric floorhead and adjusts its performance accordingly.
That means less time adjusting settings and more time simply cleaning.
Boost Mode for Extra Cleaning Power
Encounter a heavily soiled area?
Activate Boost Mode for an additional burst of cleaning performance when dealing with concentrated dirt or stubborn debris.
The integrated display keeps important information visible while you're cleaning, including your selected cleaning mode and estimated remaining battery runtime.
During charging, you can also monitor the battery's charging progress directly on the display.
HEPA Lifetime Filtration
The Triflex HX3 Aqua doesn't just remove visible dirt.
Its HEPA Lifetime Filter provides up to 99.999% exhaust air filtration, helping capture microscopic dust and airborne particles within the vacuum rather than allowing them to be released back into your home.
For households that place a high priority on filtration and indoor air quality, this is an important advantage over many conventional cordless vacuums.
Easy Twist2open Emptying
The bagless dust container holds up to 0.5 litres of debris and uses Miele's convenient Twist2open system.
Simply twist the container open over your garbage bin to release the collected dust and debris quickly and hygienically.
No vacuum bags are required.
A Complete Hard-Floor Cleaning System
The Triflex HX3 Aqua is particularly well suited to homes with significant amounts of hard flooring.
Use the MultiFloor XXL electric floorhead for everyday vacuuming, then attach the AquaTwister when you want to wet-clean your floors.
The HX3 Aqua includes two AquaPads plus 500 ml of Miele Universal Floor Cleaner, giving you what you need to start wet cleaning right out of the box.
A dedicated storage tray is also included for convenient storage of the AquaTwister system between uses.
Designed and Manufactured in Germany
The Triflex HX3 is carefully developed and manufactured in Germany by Miele.
From the interchangeable battery and patented 3-in-1 design to the AquaTwister wet-cleaning system and advanced filtration, the HX3 Aqua combines Miele's engineering heritage with a new approach to cordless floor care.
