Miele Triflex HX3 Cat & Dog Cordless Vacuum – Obsidian Black | 12878470
Miele Triflex HX3 Cat & Dog Cordless Vacuum – Obsidian Black | 12878470
The Miele Triflex HX3 Cat & Dog is the pet-focused model in the HX3 cordless family. It combines Miele's flexible 3-in-1 architecture, FloorDetect, a clear digital display, HEPA lifetime filtration and up to 70 minutes of published runtime with two important upgrades for pet households: the illuminated MultiFloor XXL electrobrush and the powered Electro Compact handheld brush for upholstery, stairs and vehicle interiors.

Why the Cat & Dog Model Is Different
The standard Triflex HX3 establishes the core platform: German manufacturing, a Digital Efficiency Motor, FloorDetect, a digital display, Boost mode, Vortex Technology, a 3-in-1 design, HEPA lifetime filtration and self-standing convenience. The Cat & Dog configuration builds on that platform with tools selected for visible pet hair and the places where it collects most often.
The SEB 435 MultiFloor XXL electrobrush adds BrilliantLight to reveal hair and fine debris across floors. The HX-EC 10 Electro Compact brush brings powered agitation to sofas, pet beds, stairs, cushions and vehicle seats—surfaces where a standard suction tool can leave embedded hair behind.
Powered Pet-Hair Cleaning Beyond the Floor
Pet hair rarely stays on one surface. It works into sofa fabric, mattress covers, carpeted steps, cushions, pet beds and vehicle upholstery. The compact powered brush is the defining accessory of this model because it delivers motorized brush action where the full floorhead is too large.
Sofas & Chairs
Loosens embedded hair from fabric seating, cushions and upholstered backs.
Pet Beds
Targets concentrated hair, lint and tracked debris on washable and upholstered pet areas.
Car Interiors
Fits vehicle seats, cargo areas and carpeted surfaces more easily than the full electrobrush.
Carpeted Stairs
Combines compact handling with active brush agitation for stair treads and landings.
One Vacuum, Three Working Configurations
Miele's patented 3-in-1 design lets the PowerUnit move to match the cleaning task rather than forcing one fixed weight distribution for every room.
Comfort Mode
Position the PowerUnit lower for balanced floor cleaning, reduced wrist load and the useful free-standing park function.
Reach Mode
Move the PowerUnit near the handle for access beneath furniture, along stairs, ceilings and elevated surfaces.
Compact Mode
Use the PowerUnit independently with the Electro Compact or hand tools for targeted pet-hair cleanup.
FloorDetect, Digital Display & One-Touch Boost
FloorDetect helps the powered MultiFloor XXL electrobrush respond as the vacuum moves between hard floors, rugs and carpet. The display keeps selected cleaning mode, battery status, estimated remaining runtime, charging percentage and Boost countdown visible while you work.
When a doorway, pet feeding area or rug has a concentrated patch of debris, Boost mode delivers a 10-second increase in vacuum power. After the countdown, it can be reactivated following the specified short wait period.
Battery Runtime: What “Up to 70 Minutes” Actually Means
The published 70-minute maximum applies to the PowerUnit Solo on the Low setting without an electrical accessory attached. Powered floor cleaning consumes more energy, so Miele publishes separate figures for operation with electrical accessories.
| Configuration | Published Runtime | Practical Use |
|---|---|---|
| PowerUnit Solo — Low | Up to 70 minutes | Handheld and non-powered accessory cleaning |
| With Electrical Accessories — Low | Up to 38 minutes | Routine powered floor or Electro Compact cleaning |
| With Electrical Accessories — High | Up to 15 minutes | More demanding powered cleaning |
| Recharge Time | Approximately 240 minutes | Full recharge of the supplied 25.2 V battery |
Actual runtime varies with flooring, selected setting, powered-tool use, debris load, battery condition and cleaning technique.
Cleaner Emptying for Hair, Dust & Dander
Twist2open lets the dust container release its contents above the trash without replacement bags. The HX3's updated metal filter cage helps debris slide away more effectively than the earlier fine-mesh design and reduces the need for direct manual cleaning of the cage.
That improvement is particularly useful in pet homes, where hair and fibrous debris can cling to internal surfaces and make routine emptying less convenient.
HEPA Filtration for More Than Visible Pet Hair
Pet ownership also brings fine particles—dander, dried soil, pollen and dust—that are less visible than hair. Miele specifies 99.999% exhaust-air filtration under its referenced HEPA testing standards for the Triflex HX3 HEPA lifetime filter.
ComfortClean supports filter performance, while the bagless 0.5-liter dust container keeps the cordless platform compact. Correct maintenance remains important: empty the container regularly, operate ComfortClean as directed and replace service items only with compatible Miele parts.
Included Tools for Floors, Furniture & Detailed Cleaning
The Cat & Dog package is built around two powered brushes plus the standard accessory set. The wall mount keeps the vacuum and frequently used tools organized between cleaning sessions.
- MultiFloor XXL electrobrush with BrilliantLight — SEB 435
- Electro Compact powered handheld brush — HX-EC 10
- Dusting brush
- XL upholstery nozzle
- Crevice nozzle
- Accessory mounting clip
- One exchangeable VARTA lithium-ion battery
- Wall mount with accessory storage
- Power supply unit
HX3 Cat & Dog vs. Brilliant White vs. Plus
The three dry-cleaning HX3 models share the same core platform but include different tools and battery packages.
| Model | Key Included Upgrade | Best For |
|---|---|---|
| Triflex HX3 Brilliant White | Core SEB 430 MultiFloor XXL package | Buyers who want the HX3 platform at the entry configuration |
| Triflex HX3 Cat & Dog | SEB 435 with BrilliantLight plus HX-EC 10 Electro Compact | Pet hair on floors, upholstery, stairs, pet beds and vehicles |
| Triflex HX3 Plus | SEB 435 with BrilliantLight, two batteries and Hardfloor Roller | Larger homes, longer cleaning sessions and extensive delicate hard flooring |
Who Should Choose This Model?
- Homes with shedding cats, dogs or multiple pets
- Owners who regularly clean sofas, stairs, pet beds and vehicle seats
- Mixed-floor homes with hard floors, rugs and carpet
- Allergy-conscious households that value HEPA exhaust-air filtration
- Buyers who want a premium replaceable-battery cordless system
- Customers who prefer German manufacturing and local authorized-dealer support
When Another HX3 May Fit Better
- Choose Brilliant White if the powered pet brush and floorhead light are not priorities
- Choose HX3 Plus if two batteries and a dedicated hard-floor roller matter more
- Choose an Aqua model if dedicated wet cleaning of water-resistant hard floors is essential
- Consider a full-size Miele canister when extended deep carpet cleaning, larger capacity or corded runtime is the priority
