An elegant and versatile device

The Miele Triflex HX3 Aqua cordless stick vacuum cleaner in Obsidian Black combines style and flexibility in a compact design. The patented 3-in-1 system allows you to switch in seconds: use it as a stick vacuum for hard floors and carpets, switch to handheld mode for furniture and upholstery, or choose Reach mode to effortlessly get under sofas and cabinets. This way, you always have the right configuration at hand, without extra devices or cumbersome fiddling with accessories. Finally, the built-in parking function keeps the device stable during a short break, without needing to lean it against anything.

Powerful vacuum cleaner that also mops

The built-in Digital Efficiency Motor and Vortex technology of the Triflex HX3 Aqua provide strong, constant suction power on both carpet and hard floors. Thanks to the FloorDetect function, the vacuum cleaner automatically recognizes the floor type and adjusts its suction power and brush roller speed accordingly. Need extra power? The Boost mode then temporarily offers 42% more power. If the dirt consists of more than just dust, you can easily attach the AquaTwister brush to vacuum and mop hard floors simultaneously. The 2 rotating pads help loosen dried-on dirt, while the integrated 360° SpotLight strip makes dust and stains visible, even in dark or hard-to-reach corners. After mopping, you can easily remove the pads and wash them at 60°C.

Clean air, without a dust cloud

Miele has equipped the Triflex HX3 Aqua with the HEPA-Lifetime filter, which captures up to 99.9% of fine dust particles and allergens, including house dust mites and pet hair. You'll notice this immediately in the air quality, especially if you are sensitive to allergic reactions or if you have pets at home. The filter is designed to last the entire lifespan of the device and normally does not need to be replaced. Furthermore, the 0.5-liter dust container is spacious enough for multiple rooms. Emptying is done via the Twist2Open system: one twist and the contents fall directly and hygienically into the trash bin without getting your hands dirty.

Accessories that make a difference

The MultiFloor XXL electric brush is equipped with BrilliantLight LED lighting that makes dust and dirt visible in places you would otherwise quickly miss. This way, you immediately see where extra attention is needed while cleaning. The included accessories make the device extra versatile: a dusting brush for delicate surfaces, an XL upholstery nozzle for sofas and cushions, and a crevice tool for narrow or hard-to-reach places. Via the digital display on the handle, you can easily monitor the remaining battery life, the selected mode, and the timer during the Boost function. Finally, the wall mount with integrated charging station keeps everything neatly stored and ensures the device is always ready for use.
