Quick Summary
The Miele Triflex HX3 Plus is a cordless stick vacuum with a Digital Efficiency Motor, FloorDetect flooring detection, and a patented 3-in-1 design. Its display shows the selected cleaning mode, remaining battery charge, and Boost timer information while you clean.
This premium set includes a second rechargeable battery, a MultiFloor XXL electrobrush with BrilliantLight, and a Hardfloor Care Tool with a soft woven nylon roller. The two batteries provide up to 140 minutes of low-level PowerUnit Solo runtime when used separately, while runtime with electrical accessories is up to 38 minutes on Low and 15 minutes on High per battery.
- Cordless Triflex HX3 stick vacuum with a Digital Efficiency Motor
- Up to 140 minutes of Low-level PowerUnit Solo runtime using two batteries
- FloorDetect adjusts power for different flooring types
- HEPA lifetime filter with stated 99.999% exhaust air filtration
- Includes a second battery and Hardfloor Care Tool
Product Overview
The Triflex HX3 Plus combines cordless convenience with a configurable design. Its PowerUnit can be positioned for Comfort, Reach, or Compact cleaning, and the vacuum can stand on its own for short parking breaks.
A Digital Efficiency Motor and three electronic suction power levels provide the core cleaning system. FloorDetect identifies the flooring and adjusts power, while the MultiFloor XXL SEB 436 electrobrush includes BrilliantLight to illuminate dust in front of the floorhead.
This model uses an exchangeable 25.2 V lithium-ion battery and includes a second battery. Miele lists up to 140 minutes of Low-level PowerUnit Solo runtime across the two batteries; when using electrical accessories, the stated runtime is up to 38 minutes on Low or 15 minutes on High per battery.
The included Hardfloor Care Tool adds a soft woven nylon roller for delicate hard floors. A dust brush, upholstery nozzle, crevice nozzle, wall mount, accessory storage, and HEPA lifetime filter round out the package.
Expert Recommendation
We recommend the HX3 Plus for shoppers who want a cordless vacuum with flexible handling, a removable battery, and a broad accessory set. The second battery is particularly relevant when you want to clean a larger area without waiting for the first battery to recharge.
Its 3-in-1 layout also makes it adaptable to different tasks: use Comfort mode for general handling, Reach mode when the PowerUnit's top position is useful, or Compact mode for quick PowerUnit Solo cleaning. If you primarily want a traditional corded vacuum or need a model with a bagged dust system, a canister or upright design may be a better fit; the supplied facts do not identify a specific sibling model with different specifications.
Best For
Allergy Sufferers
The HEPA lifetime filter is stated to provide 99.999% exhaust air filtration under the cited test standards. This makes the filtration system a central reason to consider the model when exhaust-air filtration matters.
Hardwood Floors
The included Hardfloor Care Tool uses a soft woven nylon roller for delicate hard floors. FloorDetect also identifies flooring and adjusts the vacuum's power.
Large Cleaning Areas
The package includes a second exchangeable battery, and Miele lists a cleaning area of up to 2 x 160 m². Actual results depend on the cleaning mode and accessories used.
Multi-Surface Homes
The MultiFloor XXL electrobrush is included for general floor cleaning, while FloorDetect adjusts power based on the detected flooring.
Flexible Cleaning Positions
The patented 3-in-1 design supports Comfort, Reach, and Compact configurations. This lets you change the PowerUnit position for different cleaning tasks.
Low-Light Cleaning
The MultiFloor XXL electrobrush has BrilliantLight, a bright LED front light designed to improve dust visibility.
Not Ideal For
- It is not ideal if you prefer a corded vacuum and do not want to manage battery charging; the stated recharge time is 240 minutes.
- It may not suit shoppers who prefer a bagged vacuum, because this model uses a 0.5-liter dust container.
- High-power cleaning with electrical accessories is listed at up to 15 minutes per battery, so Boost and High mode are better reserved for targeted or heavily soiled areas.
- At 8 lb, it may feel less suitable to shoppers seeking the lightest possible cordless vacuum.
Key Features
- 3-in-1 Design: Switch between Comfort, Reach, and Compact configurations for different cleaning positions and storage needs.
- FloorDetect Technology: FloorDetect identifies flooring and adjusts the vacuum's power accordingly.
- Two Batteries: The premium set includes an additional exchangeable lithium-ion battery for extended cleaning.
- HEPA Filtration: The maintenance-free HEPA lifetime filter is rated for 99.999% exhaust air filtration according to the stated testing standard.
- BrilliantLight: The MultiFloor XXL electrobrush uses a bright LED front light to help reveal dust.
- Display Controls: The display shows the selected cleaning mode, remaining cleaning time, charging status, and Boost timer information.
- Hardfloor Care Tool: The included soft woven nylon roller is designed for cleaning delicate hard floors.
- Twist2open Emptying: Twist2open releases dust from the container for hygienic emptying.
What Makes This Model Stand Out
The strongest differentiator in this package is the combination of a second battery and a configurable 3-in-1 body. You can change between the three operating layouts and continue cleaning with the additional battery rather than relying on a single battery cycle.
The cleaning tools are also thoughtfully divided by task. The MultiFloor XXL electrobrush provides floor detection and BrilliantLight, while the separate Hardfloor Care Tool uses a soft woven nylon roller for delicate hard floors; the display keeps remaining time and cleaning information visible.
Product Comparisons
Triflex HX3 Plus vs another Triflex HX3 model
The HX3 Plus is identified as part of Miele's Triflex HX3 line and includes a second battery, Hardfloor Care Tool, and MultiFloor XXL electrobrush with BrilliantLight. If you are comparing another HX3 configuration, check the included accessories and battery quantity rather than assuming the packages are identical.
Stick vs Canister
The HX3 Plus is cordless, uses a 0.5-liter dust container, and can be used in three configurations. A canister vacuum is a different format that typically separates the main body from the cleaning wand, so an in-store demonstration can help determine which handling style suits your home.
Miele vs SEBO
Miele offers this cordless Triflex stick format, while SEBO is known mainly for upright vacuums. The best choice depends on whether you prefer cordless flexibility and a removable battery or the handling style of a traditional upright; Ace Vacuums can help arrange an in-store comparison.
Miele vs Dyson
The Triflex HX3 Plus is a cordless, bagless stick vacuum with a removable battery, dust container, and three configurations. When comparing it with a Dyson model, compare the specific floorheads, battery setup, filtration, controls, and included tools rather than relying on brand-level assumptions.
Questions Buyers Commonly Ask
Is the Miele Triflex HX3 Plus worth considering?
It is worth considering if you want a cordless stick vacuum with a second battery, a 3-in-1 design, FloorDetect, and HEPA lifetime filtration. Its value depends on whether those features matter more to you than the longer continuous cleaning sessions associated with a corded vacuum.
Is it good for pet hair?
The supplied information does not identify a dedicated pet-hair tool or provide a pet-hair performance claim. It does include a MultiFloor XXL electrobrush and Boost mode for heavily soiled areas, but pet-specific suitability should be confirmed for your floors and needs.
Is the Triflex HX3 Plus quiet?
Miele lists a sound level of 74 dB. The fact pack does not provide a comparison with other vacuums, so a store demonstration is the best way to judge how the sound works for you.
Can it clean stairs?
The 3-in-1 design and Compact configuration can be useful for changing how you handle the vacuum, and the crevice nozzle and dust brush are included. The source does not make a specific stair-cleaning claim, so consider an in-store demonstration for your staircase.
Does it come with a wall mount?
Yes. The included equipment lists a wall mount, along with accessory storage and the power supply unit.

For an approved change-of-mind return, a 15% restocking fee applies to the returned merchandise price. Original shipping charges are not refundable and the customer pays return shipping. These charges do not apply to an approved return caused by our shipping error or a damaged/defective item claim. Contact us first so we can arrange the appropriate remedy and shipping instructions. Do not assume a prepaid label is included.
Final-sale and excluded items
Air purifiers; discounted, clearance, trade-in, holiday-sale and price-matched purchases; gift cards; custom or special-order products; electrical parts; used or installed items; opened cleaning solutions; and used bags, filters, belts or other consumables are not eligible for change-of-mind returns. Other items clearly marked final sale at purchase are also excluded. An opened box alone does not disqualify an otherwise eligible unused, complete item, but consumables and cleaning solutions must remain unopened.
Damaged, defective, incorrect or missing items; recalls
Inspect your order promptly and contact us as soon as you discover a problem, with your order number and photos where helpful. Keep the packaging. Change-of-mind exclusions and deadlines do not remove applicable defect, warranty, recall or statutory rights. Warranty coverage requires evaluation under the manufacturer's terms; dealer status does not guarantee free repair. Recalled products must follow the manufacturer's recall process.
Refund timing and exchanges
After we receive and inspect the return, we will notify you of approval or the reason it cannot be accepted. Approved refunds are issued to the original payment method within 10 business days of approval; your bank may take additional time to post them. Contact us if more than 15 business days have passed since approval. Exchanges require authorization and replacement availability; any price difference and applicable charges will be explained before processing.
Applicable rights and earlier purchases
This policy applies to online and in-store purchases. We will honor more favorable written return terms provided with an earlier purchase. Applicable consumer rights remain unaffected. Where the European Union 14-day cancellation right applies, customers may cancel or return eligible orders within 14 days of receipt, subject to applicable legal exceptions, without giving a reason.
