The Miele Triflex HX3 Cat & Dog Obsidian Black is a premium cordless cleaning system engineered for households that demand powerful everyday vacuuming and specialized pet-hair removal.

Combining Miele's Digital Efficiency Motor, patented 3-in-1 Triflex design, intelligent FloorDetect technology, maintenance-free HEPA lifetime filtration, illuminated cleaning, and a dedicated Electro Compact handheld brush, the HX3 Cat & Dog is designed to tackle everything from everyday dust and debris to stubborn pet hair embedded in upholstery and other fabric surfaces.

Finished in sophisticated Obsidian Black, the HX3 Cat & Dog combines Miele's high-end design with practical features throughout the home.

Powerful Digital Efficiency Motor

At the heart of the Triflex HX3 Cat & Dog is Miele's Digital Efficiency Motor.

The motor is engineered to provide strong cleaning performance across different floor surfaces, with Miele stating that the Triflex achieves 99.99% dust pickup under its specified testing conditions.

This helps the HX3 Cat & Dog thoroughly collect everyday dust, crumbs, dirt, and fine debris throughout the home.

Vortex Technology

The HX3 uses Miele's Vortex Technology as part of its cleaning system, combining the airflow and filtration system to help deliver effective dust and debris collection.

Up to 70 Minutes of Cordless Runtime

The HX3 Cat & Dog is powered by an exchangeable VARTA lithium-ion rechargeable battery.

Miele rates the battery for:

• 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

Miele specifies a cleaning area of up to approximately 160 m² under its stated conditions.

A complete recharge takes approximately 240 minutes.

Exchangeable Battery

Unlike a permanently integrated battery system, the HX3 uses an exchangeable lithium-ion battery.

The removable design provides greater flexibility for charging, storage, and battery replacement.

The battery has a nominal capacity of 2,500 mAh and operates at 25.2 V.

Intelligent FloorDetect Technology

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

This allows the HX3 Cat & Dog to adapt as you move between different surfaces throughout the home.

Instead of constantly changing settings manually, FloorDetect helps the vacuum provide appropriate cleaning performance as the floor type changes.

Patented 3-in-1 Triflex Design

The patented 3-in-1 design is one of the defining features of the HX3 platform.

The PowerUnit can be repositioned to create three different configurations.

Comfort Mode

Designed for everyday floor cleaning, Comfort mode provides a lightweight and convenient configuration for maneuvering around larger areas.

It is particularly useful when vacuuming entire rooms and larger sections of the home.

Reach Mode

In Reach mode, the PowerUnit is positioned at the top of the vacuum, creating maximum reach and flexibility.

This configuration is particularly useful for cleaning:

• Under beds
• Under sofas
• Under cabinets
• Beneath furniture
• Other difficult-to-reach areas

Compact Mode

Compact mode transforms the HX3 into a compact PowerUnit Solo configuration.

This makes it convenient for quickly cleaning:

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

The 3-in-1 design essentially gives you a full-size cordless vacuum and handheld cleaning system in one appliance.

Pet Hair Cleaning With the Electro Compact Brush

The feature that distinguishes the Cat & Dog model is its dedicated HX-EC 10 Electro Compact handheld brush.

The powered Electro Compact brush is specifically designed to pick up pet hair and dirt quickly and thoroughly from upholstery and other fabric surfaces.

It is particularly useful for cleaning:

• Sofas
• Chairs
• Pet beds
• Car seats
• Mattresses
• Upholstered furniture
• Fabric surfaces where pet hair accumulates

For households with dogs and cats, this specialized powered attachment provides a more targeted way to remove embedded hair than a standard dusting or upholstery nozzle.

BrilliantLight LED Floor Illumination

The HX3 Cat & Dog features Miele's BrilliantLight technology.

A bright LED front light illuminates the cleaning path, making dust, hair, and other debris easier to see.

This is especially useful in:

• Dark corners
• Under furniture
• Along baseboards
• Areas with shadows
• Low-light rooms

The lighting helps you identify dirt that might otherwise remain invisible during normal vacuuming.

Hardfloor Care Tool

For delicate hard flooring, the HX3 Cat & Dog includes the Hardfloor Care Tool.

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

This gives you a dedicated cleaning option when you want to clean sensitive flooring with a softer roller.

Three Electronic Suction Levels

The HX3 Cat & Dog provides three electronic suction levels.

The integrated controls allow you to select the appropriate cleaning mode depending on the surface and amount of dirt.

The available settings are displayed electronically as:

• Low
• Eco
• High

This provides greater control over cleaning performance and battery consumption.

Boost Mode

For particularly dirty or heavily soiled areas, the HX3 includes Boost mode.

Boost provides additional cleaning performance when you need it most.

The integrated display includes a Boost timer, allowing you to see how long Boost has been active.

This makes it easy to use maximum cleaning performance strategically rather than continuously.

Clear Digital Display

The integrated display provides important information while you clean.

You can see:

• Remaining battery charge
• Remaining cleaning time
• Selected cleaning mode
• Low / Eco / High setting
• Boost timer

While charging, the display can also show the charging status as a percentage.

This makes it easier to manage battery usage and plan longer cleaning sessions.

HEPA Lifetime Filtration

The Triflex HX3 Cat & Dog uses a maintenance-free HEPA lifetime filter.

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

The filtration system is designed to retain extremely fine particles within the vacuum rather than releasing them back into the surrounding air.

Miele specifically describes the HEPA lifetime filter as suitable for allergy-sensitive households.

Twist2open Hygienic Emptying

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

With a simple twist, the dust container opens and Miele states that almost 100% of the collected dust falls out.

This minimizes the need to manually reach into the dust container when emptying the appliance.

The dust container has a capacity of approximately 0.5 liters.

ComfortClean

The HX3 also incorporates Miele's ComfortClean functionality as part of its maintenance system.

Together with the lifetime HEPA filter and hygienic Twist2open dust-container design, the system is designed to make routine maintenance straightforward.

Free-Standing Park System

The patented Triflex design includes a free-standing park function.

You can stand the vacuum upright during cleaning breaks without having to lean it against a wall or place it on the floor.

This is convenient when:

• Moving furniture
• Switching accessories
• Taking a cleaning break
• Answering the door
• Picking something up

It also provides convenient upright storage between cleaning sessions.

Three-Piece Accessory Set

The HX3 Cat & Dog includes a three-piece accessory set for cleaning areas beyond the floor.

HX-DB Dust Brush

Designed for dusting and gently cleaning delicate surfaces.

XL HX-UN Upholstery Nozzle

The wide upholstery nozzle is designed for cleaning:

• Sofas
• Chairs
• Mattresses
• Upholstered furniture
• Fabric surfaces

HX-CN Crevice Nozzle

Designed for cleaning narrow gaps, corners, edges, and difficult-to-reach spaces.

These accessories complement the specialized Electro Compact pet-hair brush and expand the vacuum's usefulness throughout the home.

Complete Included Package

The Miele Triflex HX3 Cat & Dog Obsidian Black includes:

• Triflex HX3 Cat & Dog
• VARTA lithium-ion rechargeable battery
• HX-EC 10 Electro Compact powered handheld brush
• Hardfloor Care Tool
• HX-DB Dust Brush
• XL HX-UN Upholstery Nozzle
• HX-CN Crevice Nozzle
• HX-AH accessory storage
• Wall mount
• Power supply unit

This gives the Cat & Dog model a particularly comprehensive combination of dry vacuuming, pet-hair cleaning, delicate hard-floor care, wet cleaning, upholstery cleaning, and crevice cleaning.

Premium Obsidian Black Design

The HX3 Cat & Dog is finished in Obsidian Black, giving the vacuum a sophisticated premium appearance.

Miele's Family Design concept is intended to allow the appliance to blend naturally into contemporary interiors rather than looking like a purely utilitarian cleaning appliance.

The wall-mounting system also provides a clean and organized storage solution.

German Engineering

Why the Cat & Dog Model Stands Out

The Triflex HX3 Cat & Dog takes the standard HX3 platform and adds features particularly valuable to pet owners.

Powerful Everyday Vacuuming

Miele's Digital Efficiency Motor provides high cleaning performance and up to 99.99% dust pickup under specified conditions.

Dedicated Pet-Hair Cleaning

The Electro Compact powered brush is designed specifically to pick up pet hair and dirt from upholstery and fabric surfaces.

Intelligent Floor Cleaning

FloorDetect recognizes flooring and adjusts power automatically.

Illuminated Cleaning

Wet Floor Cleaning

The AquaTwister adds rotating-pad wet cleaning for stubborn and dried-on dirt on suitable water-resistant floors.

Advanced Filtration

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

Flexible 3-in-1 Design

Comfort, Reach, and Compact configurations allow the vacuum to adapt to different cleaning situations.

Long Cordless Runtime

The exchangeable lithium-ion battery provides up to 70 minutes of PowerUnit Solo runtime on Low.

Hygienic Dust Emptying

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

Convenient Storage

The Ideal Miele for Pet Owners

The Miele Triflex HX3 Cat & Dog Obsidian Black is designed to be a complete cordless cleaning solution for households where pet hair, dust, dirt, upholstery, and hard floors are part of everyday life.

Its combination of Digital Efficiency Motor performance, FloorDetect intelligence, HEPA lifetime filtration, BrilliantLight illumination, 3-in-1 flexibility, Electro Compact pet-hair brush, and Hardfloor Care Tool makes it considerably more versatile than a basic cordless stick vacuum.

The dedicated Electro Compact brush is the standout Cat & Dog feature, providing a powered handheld tool specifically intended to remove pet hair and dirt from furniture, upholstery, seats, and other fabric surfaces.

At the same time, the AquaTwister provides a second layer of versatility by allowing the system to address stubborn and dried-on dirt on suitable water-resistant floors.

From dog hair on the sofa and cat fur on furniture to crumbs on the kitchen floor, dust underneath the bed, dirt along baseboards, and dried-on floor messes, the HX3 Cat & Dog is designed to handle the cleaning challenges of a pet-friendly home.
