The Miele Triflex HX3 Brilliant White is a premium cordless stick vacuum designed to combine powerful everyday cleaning, intelligent floor detection, advanced HEPA filtration, flexible handling, and convenient cordless operation in one sophisticated system.

Powered by Miele's Digital Efficiency Motor, the Triflex HX3 delivers up to 99.99% dust pickup under Miele's specified test conditions. Its patented 3-in-1 design allows the vacuum to be configured for maximum comfort, extended reach, or compact handheld cleaning, while an interchangeable VARTA lithium-ion battery provides up to 70 minutes of runtime in PowerUnit Solo operation on Low.

Finished in Brilliant White, the HX3 is designed to combine Miele's high-end aesthetic with practical functionality throughout the home.

Powerful Cleaning Performance

Digital Efficiency Motor

At the heart of the Triflex HX3 is Miele's Digital Efficiency Motor, engineered to provide strong suction performance across different flooring types.

Miele states that the HX3 achieves 99.99% dust pickup, helping remove fine dust, dirt, and everyday debris for thorough cleaning.

The vacuum provides three electronic suction levels, allowing you to select the appropriate cleaning performance for different situations.

Boost Mode

When additional power is needed, Boost mode provides extra performance for heavily soiled areas.

Boost is particularly useful when encountering concentrated dirt or areas that require a more intensive cleaning pass.

The integrated display provides a Boost timer, allowing you to monitor how long the extra-power mode is being used.

Up to 70 Minutes of Cordless Runtime

The HX3 is equipped with a VARTA lithium-ion rechargeable battery with a nominal capacity of 2,500 mAh.

Miele rates the vacuum for:

• Up to 70 minutes of runtime in PowerUnit Solo on Low
• Up to 38 minutes with electrical accessories on Low
• Up to 15 minutes with electrical accessories on High

The specified cleaning area is up to approximately 160 m², depending on operating conditions.

A full recharge takes approximately 240 minutes.

Exchangeable Battery

The battery is exchangeable, allowing it to be removed from the appliance rather than permanently built into the vacuum.

This provides additional flexibility for charging, storage, and future battery management.

Intelligent FloorDetect Technology

The FloorDetect system automatically detects the type of flooring being cleaned and adjusts the vacuum's power accordingly.

Instead of requiring you to manually change the power every time you move between surfaces, FloorDetect helps the HX3 adapt its cleaning performance as you move through your home.

This makes the vacuum particularly convenient for homes containing a combination of flooring surfaces.

Patented 3-in-1 Triflex Design

One of the defining features of the HX3 is Miele's patented 3-in-1 design.

The PowerUnit can be positioned differently depending on the cleaning task, giving you three distinct configurations:

Comfort Mode

Designed for effortless everyday floor cleaning.

The configuration keeps the vacuum comfortable and easy to handle, making it well suited to cleaning larger areas.

Reach Mode

The PowerUnit is positioned at the top of the vacuum to provide maximum flexibility and reach.

This configuration is particularly useful when cleaning underneath furniture and other areas where additional reach is helpful.

Compact Mode

The PowerUnit Solo configuration allows you to quickly convert the HX3 into a compact cordless cleaning appliance.

It is useful for:

• Stairs
• Furniture
• Upholstery
• Shelves
• Counters
• Cars
• Small spills
• Tight spaces

The 3-in-1 system means the HX3 can function as a full-size floor vacuum and a compact handheld vacuum without requiring a separate appliance.

Free-Standing Park System

The Triflex HX3 includes a free-standing park function, allowing you to temporarily stand the vacuum upright during cleaning breaks.

You don't have to lean the vacuum against furniture or lay it on the floor every time you need to stop.

This also makes the vacuum convenient to store between cleaning sessions.

Advanced HEPA Lifetime Filtration

The HX3 uses a maintenance-free HEPA lifetime filter.

Miele specifies 99.999% exhaust-air filtration according to its stated testing conditions.

The HEPA filtration system is designed to retain extremely fine particles within the appliance rather than releasing them back into the room.

Miele specifically describes the filtration as suitable for households where maintaining clean exhaust air is important, including allergy-sensitive environments.

Hygienic Twist2open Dust Emptying

Emptying the dust container is designed to be simple with Miele's Twist2open system.

With a simple twisting action, the dust container opens and Miele states that almost 100% of the collected dust can fall out.

This helps minimize contact with the collected dirt and makes routine emptying quick and hygienic.

The dust container has a capacity of approximately 0.5 liters.

Clear Digital Display

The HX3 features an integrated display that keeps important cleaning information visible while you work.

The display shows:

• Remaining battery charge
• Remaining cleaning time
• Selected cleaning mode
• Low mode
• Eco mode
• High mode
• Boost timer
• Charging percentage while the battery is charging

The remaining-runtime information helps you plan your cleaning session and better manage available battery power.

Hardfloor Care Tool

The HX3 Brilliant White includes Miele's Hardfloor Care Tool.

This tool features a soft woven nylon roller designed for gentle cleaning of delicate hard floors.

It provides a softer cleaning option for sensitive flooring where you want to minimize aggressive contact while still collecting dust and debris effectively.

Three-Piece Accessory Set

The HX3 includes a versatile three-piece accessory collection for cleaning areas beyond the floor.

HX-DB Dust Brush

Designed for dusting and cleaning delicate surfaces.

XL HX-UN Upholstery Nozzle

The wide upholstery nozzle is designed for cleaning:

• Sofas
• Chairs
• Mattresses
• Upholstered furniture
• Other fabric surfaces

HX-CN Crevice Nozzle

The crevice tool is designed for narrow gaps, corners, edges, and difficult-to-reach spaces.

Complete Included Accessories

The Miele Triflex HX3 Brilliant White comes with:

• HX-DB Dust Brush
• XL HX-UN Upholstery Nozzle
• HX-CN Crevice Nozzle
• Hardfloor Care Tool
• HX-AH Accessory Storage
• Wall Mount
• Power Supply Unit

This gives the HX3 a broad range of cleaning capabilities straight out of the box.

High-End Family Design

Miele describes the HX3 as part of its family design concept, combining a stylish appearance with high-quality workmanship.

The Brilliant White finish gives the vacuum a clean, modern appearance designed to blend into contemporary interiors rather than looking like a conventional utility appliance.

Its wall-mounting capability also allows it to be conveniently stored while keeping the floor clear.

German Engineering

The Triflex HX3 is developed and manufactured in Germany by Miele & Cie. KG.

Miele states that its Triflex models are designed around its performance and quality standards, combining the company's engineering heritage with a modern cordless vacuum platform.
