Launching September 3, 2026
Miele is introducing a new generation of cordless floor care with the Triflex HX3 Series, and this launch brings more than a routine model update.
The new lineup includes five Miele Triflex HX3 cordless vacuums, ranging from a versatile everyday model to pet-focused, extended-runtime, and new wet-cleaning options:
-
Miele Triflex HX3
-
Miele Triflex HX3 Cat & Dog
-
Miele Triflex HX3 Plus
-
Miele Triflex HX3 Aqua
-
Miele Triflex HX3 Aqua Plus
Across the lineup, Miele has improved runtime, introduced a new digital display and Boost Mode, redesigned the dustbin filter cage for more hygienic emptying, and retained the flexible 3-in-1 design that lets you configure the vacuum for different cleaning jobs.
The biggest news, however, is the arrival of the Triflex HX3 Aqua and Triflex HX3 Aqua Plus. These models introduce wet cleaning to the Triflex family with Miele's new AquaTwister floorhead.
If you're wondering which new Miele cordless vacuum is right for your home, here's what you need to know before choosing.
What's New With the Miele Triflex HX3 Series?
The Triflex HX3 builds on the flexibility of Miele's previous Triflex cordless vacuums while adding several meaningful upgrades.
Longer Runtime
Miele says software changes allow the HX3 to make better use of its battery without reducing cleaning performance or power. Depending on the model and configuration, the new generation provides up to 26% more runtime than the Triflex HX2.
Single-battery models offer up to 70 minutes of maximum battery runtime, while the two-battery Triflex HX3 Plus and HX3 Aqua Plus can provide up to 140 minutes of combined maximum runtime.
That means fewer charging interruptions when you're working through a larger home.
New Digital Display
Miele has replaced the previous manual slider with an intuitive digital display and three push-button controls.
The display can show information such as:
-
Selected cleaning mode
-
Battery and charging status
-
Remaining runtime
-
Boost Mode countdown
For regular vacuuming, you can choose from Low, Eco, and High power settings.
Boost Mode for Extra-Dirty Areas
Need extra cleaning power for a particularly messy spot?
Press Boost Mode and the HX3 delivers 10 seconds of boosted vacuum power. The display counts down the remaining Boost time, so you know exactly when the cycle will finish.
On the AquaTwister, Boost works differently: it provides 30 seconds of boosted wetting intensity for areas that need additional attention.
More Hygienic Dustbin Emptying
Miele has also redesigned the filter cage.
Instead of the previous fine-mesh filter cage, the HX3 uses stainless steel gauze. According to Miele, particles slide out of the dustbin more effectively with the new design, reducing the need to manually clean the filter cage.
It's a small design change that can make everyday vacuum maintenance more convenient.
Automatic FloorDetect
Every HX3 model includes FloorDetect, allowing the vacuum to adapt its cleaning behavior as you move across different flooring.
Combined with Miele's powered floorheads, this makes the HX3 lineup better suited to homes where cleaning involves moving between carpet and hard flooring.
Flexible 3-in-1 Design
All five models retain Miele's flexible 3-in-1 Triflex configuration, giving you three ways to clean:
Comfort Mode: Designed for everyday floor cleaning, with the power unit positioned lower on the vacuum.
Reach Mode: Repositions the power unit to help you clean areas such as ceilings and underneath furniture.
Compact Mode: Converts the vacuum into a handheld configuration for furniture, stairs and other smaller cleaning jobs.
The standard vacuum configuration can also stand upright on its own in Comfort Mode when used with the Electrobrush. Miele notes that the AquaTwister itself does not support self-standing.
Meet the Five New Miele Triflex HX3 Vacuums
Although the five models share the same HX3 platform, their included tools, batteries and cleaning capabilities make them suited to different households.
Here's how they compare.
1. Miele Triflex HX3: The Everyday All-Rounder
Color: Brilliant White
Maximum battery runtime: Up to 70 minutes
Battery: 1
Floorhead: MultiFloor XXL / SEB 430
Filter: Lifetime HEPA with ComfortClean
Miele listed UMRP/MAP: $849
The standard Miele Triflex HX3 is the entry point into the new series and gives you the core HX3 improvements without adding specialized pet, hard-floor or wet-cleaning accessories.
It includes the MultiFloor XXL SEB 430 Electrobrush, along with a dusting brush, upholstery nozzle and crevice nozzle.
You also get the features found throughout the new lineup, including the Digital Efficiency Motor, FloorDetect, digital controls, Boost Mode, three power settings and Lifetime HEPA filtration.
Who Is the Triflex HX3 Best For?
The standard HX3 makes sense if you want a premium Miele cordless vacuum for everyday cleaning but don't need a pet-specific powered handheld tool, a second battery or wet mopping.
What makes it unique: It's the most accessible way to get the new HX3 platform and its major performance and usability upgrades.
2. Miele Triflex HX3 Cat & Dog: Built With Pet Homes in Mind
Color: Obsidian Black
Maximum battery runtime: Up to 70 minutes
Battery: 1
Floorhead: MultiFloor XXL / SEB 435 with BrilliantLight
Additional tool: Electro Compact HX-EC10
Filter: Lifetime HEPA with ComfortClean
Miele listed UMRP/MAP: $999
Pet hair doesn't always stay on the floor. It collects on furniture, stairs and other upholstered surfaces too, which is where the Miele Triflex HX3 Cat & Dog separates itself from the standard model.
The Cat & Dog includes Miele's SEB 435 powered floorhead with BrilliantLight, helping illuminate the cleaning area as you vacuum.
More importantly for pet owners, it comes with the Electro Compact HX-EC10 handheld brush. This powered accessory gives you another option for tackling pet hair and debris on smaller surfaces.
You still get one battery with up to 70 minutes of maximum runtime, along with the new digital controls, Boost Mode, FloorDetect and Lifetime HEPA filtration.
Who Is the Triflex HX3 Cat & Dog Best For?
This is the HX3 to consider if you regularly deal with pet hair across floors, stairs, furniture and other surfaces.
What makes it unique: The combination of the illuminated SEB 435 floorhead and included Electro Compact handheld brush gives pet households more specialized cleaning capability.
3. Miele Triflex HX3 Plus: More Runtime and Hard-Floor Flexibility
Color: Titanium Pearl Finish
Maximum battery runtime: Up to 140 minutes with two batteries
Batteries: 2
Floorhead: MultiFloor XXL / SEB 435 with BrilliantLight
Hard-floor roller: Included
Filter: Lifetime HEPA with ComfortClean
Miele listed UMRP/MAP: $1,099
The Miele Triflex HX3 Plus is designed for buyers who want more cleaning time and additional floor-care flexibility without moving into wet cleaning.
The biggest upgrade is the inclusion of two lithium-ion batteries. Miele lists maximum battery runtime at up to 140 minutes using the two batteries, compared with up to 70 minutes for the single-battery HX3 and Cat & Dog.
It also includes the illuminated SEB 435 floorhead and Miele's Hardfloor Care Tool/Roller, giving you an additional tool specifically for hard-floor cleaning.
Who Is the Triflex HX3 Plus Best For?
Consider the Plus if you have a larger home, longer cleaning sessions, substantial hard flooring or simply want the flexibility of a second battery.
What makes it unique: Among the non-Aqua models, it provides the most complete package, combining two batteries, BrilliantLight and the dedicated hard-floor accessory.
4. Miele Triflex HX3 Aqua: Vacuuming Meets Wet Cleaning
Color: Obsidian Black
Maximum vacuum battery runtime: Up to 70 minutes
Battery: 1
Vacuum floorhead: SEB 435 with BrilliantLight
Wet-cleaning floorhead: AquaTwister
Wet settings: 3
AquaTwister lighting: 360° light
Filter: Lifetime HEPA with ComfortClean
Miele listed UMRP/MAP: $1,049
The Miele Triflex HX3 Aqua represents the biggest change to the Triflex family.
For the first time in this lineup, Miele has added a dedicated wet-cleaning solution through its new AquaTwister floorhead.
This means the same HX3 platform can handle traditional cordless vacuuming and wet floor cleaning by switching floorheads.
How Does the Miele AquaTwister Work?
The AquaTwister features an integrated, removable 300 ml clean-water container. Miele says a tank can cover approximately 150 square meters, or about 1,614 square feet, depending on use.
There are three selectable wetness settings:
-
0
-
1
-
2
This lets you control the amount of moisture being applied based on the cleaning situation.
The AquaTwister also features 360° lighting, making it easier to see the floor and cleaning area around the head.
When you need additional wetting for a stubborn area, Aqua Boost Mode opens the water valve for 30 seconds of boosted wetting intensity.
Machine-Washable AquaPads
The AquaTwister uses removable AquaPads made with a combination of looped fibers, twisted fibers and sponge material to help with cleaning and absorption.
Miele says the pads can be machine washed at up to 140°F / 60°C and were tested for 100 hours of washing.
The HX3 Aqua includes two washable AquaPads and a drip tray.
Miele FloorClean Is Included
Each HX3 Aqua also comes with a 17 fl. oz. bottle of Miele FloorClean.
The cleaning solution is designed for water-resistant flooring and is formulated for streak-free cleaning without buildup. Miele also describes it as a low-foam, easily biodegradable formula.
For dosing, Miele recommends adding half a cap to the AquaTwister water container per use. According to Miele, one bottle provides approximately 25 cleanings.
Who Is the Triflex HX3 Aqua Best For?
The Aqua is worth considering if you want the versatility of cordless vacuuming plus a dedicated wet-cleaning system for appropriate hard flooring without stepping up to the two-battery Aqua Plus.
What makes it unique: It brings Miele's new AquaTwister wet-cleaning system to the Triflex lineup at a lower price than the Aqua Plus.
5. Miele Triflex HX3 Aqua Plus: The Most Complete HX3 Package
Color: Obsidian Black
Maximum battery runtime: Up to 140 minutes with two batteries
Batteries: 2
Vacuum floorhead: SEB 435 with BrilliantLight
Wet-cleaning floorhead: AquaTwister with 360° light
Hard-floor roller: Included
Wet settings: 3
Filter: Lifetime HEPA with ComfortClean
Miele listed UMRP/MAP: $1,249
At the top of the new lineup sits the Miele Triflex HX3 Aqua Plus.
It takes the wet-cleaning capabilities of the HX3 Aqua and combines them with the expanded accessory and battery package of the HX3 Plus.
You get:
-
Two lithium-ion batteries
-
SEB 435 powered vacuum floorhead with BrilliantLight
-
AquaTwister wet-cleaning floorhead
-
360° AquaTwister lighting
-
Two washable AquaPads
-
17 fl. oz. bottle of Miele FloorClean
-
AquaTwister drip tray
-
Hard-floor roller
-

The two-battery configuration provides up to 140 minutes of maximum combined battery runtime, giving larger homes considerably more cleaning flexibility.
Who Is the Triflex HX3 Aqua Plus Best For?
This is the model for buyers who want the broadest cleaning capability in the new HX3 lineup.
If your home combines carpets, rugs and hard flooring and you want both dry vacuuming and wet cleaning, plus longer potential runtime, the Aqua Plus offers the most comprehensive package.
What makes it unique: It's the all-in-one flagship of the five-model lineup, combining wet cleaning, two batteries, BrilliantLight and the dedicated hard-floor accessory.

HX3 vs. HX3 Cat & Dog: Which Should You Choose?
Choose the standard HX3 if you want the essential features of the new series and primarily need straightforward floor and handheld cleaning.
Move to the HX3 Cat & Dog if pet hair is a regular challenge. Its powered Electro Compact handheld brush and illuminated SEB 435 floorhead make the additional investment more relevant for pet households.
HX3 Plus vs. HX3 Aqua: What's the Difference?
This comparison comes down to what kind of versatility matters more.
The HX3 Plus gives you two batteries and a dedicated hard-floor roller, making it better suited to longer dry-vacuuming sessions.
The HX3 Aqua uses one battery but adds the AquaTwister wet-cleaning system.
So if runtime is your priority, look toward the Plus. If you want one Triflex platform capable of both vacuuming and wet floor cleaning, the Aqua is the more natural choice.
HX3 Aqua vs. HX3 Aqua Plus: Is the Plus Worth It?
Both Aqua models include the same core wet-cleaning concept, including the AquaTwister, three wet-level settings, 360° lighting, washable pads, FloorClean and drip tray.
The Aqua Plus adds a second battery and the hard-floor roller.
For smaller or moderate cleaning areas, the single-battery Aqua may provide everything you need. For larger homes or buyers who want the most complete accessory package, the Aqua Plus offers greater flexibility.
What Is Miele FloorDetect?
FloorDetect is included across all five HX3 models.
The feature allows the vacuum to detect the floor surface and adjust accordingly, helping the vacuum transition between flooring types without requiring constant manual adjustment.
For homes with a mixture of carpet, area rugs and hard floors, this can make everyday cleaning feel much more natural.
Does the Miele Triflex HX3 Have a HEPA Filter?
Yes. Every model in the new Miele Triflex HX3 lineup uses a Lifetime HEPA filter with ComfortClean.
That means HEPA filtration isn't reserved for the more expensive Plus or Aqua models. It's part of the core HX3 platform.
How Long Does the Miele Triflex HX3 Battery Last?
Maximum runtime depends on the model, power setting, floorhead and cleaning configuration.
Miele lists up to 70 minutes of maximum battery runtime for the single-battery HX3, HX3 Cat & Dog and HX3 Aqua.
The HX3 Plus and HX3 Aqua Plus include two batteries and are listed with up to 140 minutes of maximum battery runtime using both batteries.
Miele's technical material also lists a 240-minute, or four-hour, battery recharge time.
Actual cleaning time will vary depending on the setting and floorhead being used.
Can the Miele Triflex HX3 Mop Floors?
The Triflex HX3 Aqua and Triflex HX3 Aqua Plus provide wet-cleaning capability through the AquaTwister floorhead.
The standard HX3, Cat & Dog and Plus are dry vacuuming models, although Miele states that the AquaTwister accessory is compatible with the HX3 platform.
For wet cleaning, always follow Miele's instructions and your flooring manufacturer's care requirements. Miele specifically notes that while the AquaPads themselves are safe on most flooring types, water and cleaning solution may not be appropriate for every floor.
Which Miele Triflex HX3 Is Best for Pet Hair?
The Triflex HX3 Cat & Dog is the model specifically equipped for pet households.
Its included Electro Compact powered handheld brush gives you an additional way to remove pet hair from smaller surfaces, while the SEB 435 floorhead adds BrilliantLight for better visibility while cleaning.
If you have pets but also want wet floor cleaning, the Aqua models may be worth comparing based on the types of surfaces in your home.
Which Miele Triflex HX3 Has the Longest Runtime?
The Triflex HX3 Plus and Triflex HX3 Aqua Plus offer the greatest maximum runtime because both include two batteries.
Miele lists these configurations at up to 140 minutes total maximum battery runtime.
The other three models include one battery and are rated for up to 70 minutes.
Which New Miele HX3 Should You Choose?
There's no single best HX3 for every home. The advantage of the five-model lineup is that you can choose based on the way you actually clean.
Choose the Triflex HX3 if:
You want the core HX3 experience at the lowest price in the lineup.
Choose the Triflex HX3 Cat & Dog if:
You have pets and want an included powered handheld brush for pet hair and smaller surfaces.
Choose the Triflex HX3 Plus if:
You want longer potential runtime, two batteries and additional hard-floor cleaning capability.
Choose the Triflex HX3 Aqua if:
You want to add wet cleaning to your cordless vacuum routine without paying for the full Aqua Plus package.
Choose the Triflex HX3 Aqua Plus if:
You want the most complete model, with wet cleaning, two batteries and additional hard-floor capability.
