The Miele Triflex HX3 Plus Aqua Obsidian Black is a premium cordless cleaning system engineered to deliver powerful vacuuming, intelligent floor detection, advanced filtration, and wet-floor cleaning in one versatile appliance.

Designed and manufactured in Germany, the HX3 Plus Aqua combines Miele's Digital Efficiency Motor, patented 3-in-1 Triflex design, FloorDetect technology, HEPA lifetime filtration, AquaTwister wet-cleaning system, illuminated cleaning technology, and an additional rechargeable battery for extended cleaning sessions.

With two VARTA lithium-ion batteries included, the HX3 Plus Aqua provides up to 140 minutes of total runtime, making it particularly well suited for larger homes and extended cleaning sessions.

Powerful Digital Efficiency Motor

At the heart of the Triflex HX3 Plus Aqua is Miele's Digital Efficiency Motor, designed to deliver high cleaning performance across a variety of flooring.

Miele states that the Triflex HX3 achieves 99.99% dust pickup under its specified test conditions, helping remove dust, dirt, and debris for thorough everyday cleaning.

The electronic suction system provides three cleaning levels, while Boost mode supplies additional performance when tackling heavily soiled areas.

Up to 140 Minutes of Total Runtime

The HX3 Plus Aqua includes two interchangeable VARTA lithium-ion rechargeable batteries.

Each battery provides:

• Up to 70 minutes using the PowerUnit Solo on Low
• Up to 38 minutes with electrical accessories on Low
• Up to 15 minutes with electrical accessories on High

Because the Plus model includes a second battery, Miele rates the combined PowerUnit Solo runtime at up to 140 minutes.

This makes the HX3 Plus Aqua particularly useful for cleaning larger homes without having to wait for the vacuum to recharge between sessions.

The batteries are exchangeable, allowing one battery to be used while the other is charged.

A full recharge takes approximately 240 minutes.

AquaTwister Wet-Cleaning System

The defining feature of the HX3 Plus Aqua is its AquaTwister wet-cleaning attachment.

The AquaTwister combines vacuuming and wet-floor care capabilities, using rotating cleaning pads and adjustable water volume to help remove stubborn and dried-on dirt from suitable water-resistant flooring.

Rather than relying solely on traditional mopping, the rotating pads actively work against stubborn marks while the adjustable water flow lets you control the amount of moisture applied.

This makes the AquaTwister ideal for everyday messes, dried-on spots, and routine hard-floor maintenance.

360° SpotLight

The AquaTwister features a 360-degree SpotLight designed to illuminate the floor around the cleaning head.

The integrated lighting helps reveal dust, dirt, and debris that can be difficult to see under normal room lighting—including areas underneath furniture and in darker sections of the room.

This allows you to see what you are cleaning rather than relying solely on what is visible from overhead lighting.

BrilliantLight LED Floor Illumination

The HX3 Plus Aqua also incorporates Miele's BrilliantLight technology.

The bright LED front light helps illuminate the cleaning path and makes fine dust and debris easier to detect.

Combined with the AquaTwister's 360-degree lighting, the HX3 Plus Aqua is designed to make hidden dirt more visible while cleaning.

Intelligent FloorDetect Technology

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

This allows the HX3 Plus Aqua to adapt as you move throughout your home, helping provide appropriate cleaning performance across different floor surfaces.

Patented 3-in-1 Triflex Design

The HX3 Plus Aqua can be configured in three different ways to suit different cleaning situations.

Comfort Mode

The PowerUnit is positioned lower on the vacuum to create a comfortable configuration for everyday floor cleaning.

This configuration helps make the vacuum easier to maneuver and comfortable for extended cleaning sessions.

Reach Mode

The PowerUnit moves to the top of the vacuum, creating a configuration optimized for reaching underneath furniture and into difficult-to-access areas.

This configuration provides greater reach and flexibility when cleaning floors beneath beds, sofas, cabinets, and other furniture.

Compact Mode

Remove the wand and floorhead and use the PowerUnit Solo for quick, compact cleaning.

Compact mode is useful for:

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

The 3-in-1 system effectively allows the HX3 Plus Aqua to function as a full-size cordless vacuum and a compact handheld cleaning appliance.

Convenient Self-Standing Park Function

The Triflex HX3 Plus Aqua incorporates a free-standing park system.

You can temporarily park the vacuum during cleaning breaks without needing to lean it against a wall or lay it on the floor.

This is particularly convenient when you need to move furniture, answer the door, pick something up, or switch cleaning tools.

The free-standing design also makes the appliance easier to store between cleaning sessions.

HEPA Lifetime Filtration

The HX3 Plus Aqua features a maintenance-free HEPA lifetime filter.

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

The filtration system is designed to retain extremely fine particles within the appliance, helping provide cleaner exhaust air during operation.

The lifetime filter eliminates the need for routine filter replacement under normal use.

Twist2Open Hygienic Dust Emptying

Emptying the dust container is designed to be quick and hygienic with Miele's Twist2open system.

A simple twist opens the dust container, allowing almost 100% of the collected dust to fall out.

This reduces the need to reach inside the container to remove accumulated dirt and debris.

The dust container has a capacity of approximately 0.5 liters.

Clear Digital Display

The integrated display provides important cleaning information at a glance.

During cleaning, the display can show:

• Remaining battery runtime
• Selected cleaning mode
• Low, Eco, or High mode
• Boost-mode timer

While charging, the display provides the charging status as a percentage.

The remaining-time display also helps you manage your cleaning session and determine when it may be useful to switch batteries.

Three Electronic Cleaning Levels

The HX3 Plus Aqua provides three electronic suction settings.

This allows you to select the appropriate cleaning level for different surfaces and cleaning requirements.

For heavily soiled areas, Boost mode provides additional performance when you need it most.

Hardfloor Care Tool

Included with the Plus Aqua is Miele's Hardfloor Care Tool.

It uses a soft woven nylon roller designed for gentle cleaning of delicate hard flooring.

This provides an alternative to the more aggressive cleaning action of the AquaTwister when you want to clean sensitive hard surfaces more gently.

Comprehensive Cleaning Accessories

The HX3 Plus Aqua includes a complete collection of tools for cleaning floors, furniture, upholstery, tight spaces, and other areas.

HX-DB Dust Brush

Designed for dusting surfaces and cleaning delicate areas.

XL HX-UN Upholstery Nozzle

The larger upholstery nozzle is designed for furniture, upholstery, mattresses, and other fabric-covered surfaces.

HX-CN Crevice Nozzle

Designed for narrow spaces, gaps, corners, and other difficult-to-reach areas.

Hardfloor Care Tool

Uses a soft woven nylon roller for gentler cleaning of delicate hard floors.

AquaTwister

Provides wet-cleaning capability with rotating pads and adjustable water flow.

AquaPad 2

Included for use with the AquaTwister wet-cleaning system.

Complete Included Package

The Miele Triflex HX3 Plus Aqua includes:

• Triflex HX3 Plus Aqua PowerUnit
• VARTA lithium-ion rechargeable battery
• Additional VARTA lithium-ion rechargeable battery
• HX-DB Dust Brush
• XL HX-UN Upholstery Nozzle
• HX-CN Crevice Nozzle
• Hardfloor Care Tool
• AquaTwister
• AquaPad 2
• 500 mL universal cleaning solution
• Cleaning-solution voucher
• Accessory storage HX-AH
• Wall mount
• Power supply
• Storage tray

The second battery is one of the most significant differences between the HX3 Plus Aqua and the standard HX3 Aqua, effectively doubling the available PowerUnit Solo runtime from up to 70 minutes to up to 140 minutes.

Designed for Large Homes

With two batteries and a total rated PowerUnit Solo runtime of up to 140 minutes, the HX3 Plus Aqua is designed to handle substantially larger cleaning areas without requiring a mid-cleaning recharge.

Miele lists a combined cleaning area of up to 320 m² under its specified conditions.

This makes the Plus model particularly attractive for larger homes, multi-level houses, and users who want to clean multiple areas in a single session.

Premium German Engineering

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

Its design combines Miele's emphasis on premium construction with a modern cordless form factor and a versatile cleaning system.

The Obsidian Black finish gives the appliance a sophisticated, understated appearance intended to integrate naturally into a modern home.

Why the HX3 Plus Aqua Stands Out

The Miele Triflex HX3 Plus Aqua Obsidian Black combines several cleaning technologies that are normally found in separate appliances:

Vacuum

Powerful cordless dry vacuuming with Miele's Digital Efficiency Motor and up to 99.99% dust pickup under specified conditions.

Intelligent Cleaning

FloorDetect automatically recognizes flooring and adjusts power.

Wet Cleaning

The AquaTwister uses rotating pads and adjustable water flow to help tackle dried-on dirt and stains.

Deep-Dirt Visibility

BrilliantLight and the AquaTwister's 360-degree SpotLight illuminate dust and debris that may otherwise remain hidden.

Advanced Filtration

The maintenance-free HEPA lifetime filter provides 99.999% exhaust-air filtration according to Miele's specified standards.

Maximum Flexibility

The patented 3-in-1 design provides Comfort, Reach, and Compact configurations.

Extended Runtime

Two interchangeable batteries provide up to 140 minutes of combined PowerUnit Solo runtime.

Hygienic Maintenance

Twist2open allows almost all collected dust to be released from the container with a simple twist.

The Complete Miele Cleaning Experience

The Miele Triflex HX3 Plus Aqua Obsidian Black is designed as a complete cordless cleaning solution rather than simply a stick vacuum.

It combines high-performance dry vacuuming, intelligent floor detection, illuminated cleaning, HEPA filtration, handheld versatility, delicate-floor care, and powered wet cleaning in a single system.

The included second battery makes the Plus model especially suited to larger homes and longer cleaning sessions, while the AquaTwister adds a dedicated wet-cleaning capability for hard floors.

From everyday dust and crumbs to fine particles, stubborn debris, furniture, stairs, delicate hard floors, and dried-on floor marks, the HX3 Plus Aqua is engineered to provide a versatile cleaning solution with the convenience of cordless operation.

Miele Triflex HX3 Plus Aqua — powerful cordless vacuuming, intelligent floor care, and wet cleaning, with the freedom of two batteries.
