Quick Summary
The Miele Triflex HX3 Plus Aqua combines cordless vacuuming with wet floor cleaning in a flexible 3-in-1 design. Its AquaTwister attachment uses rotating pads, adjustable water volume, and integrated 360-degree lighting to help reveal and remove everyday dirt from hard floors.
A Digital Efficiency Motor, three electronic suction settings, Boost mode, FloorDetect, and a HEPA lifetime filter give the HX3 Plus Aqua a broad range of cleaning options. The package also includes a second battery, a MultiFloor XXL electrobrush, a Hardfloor Care Tool, two AquaPads, and other everyday accessories.
- Cordless stick vacuum with AquaTwister wet cleaning attachment
- Up to 140 minutes of low-level PowerUnit Solo runtime with two batteries
- 3-in-1 design for Comfort, Reach, and Compact configurations
- HEPA lifetime filter with stated 99.999% exhaust air filtration
- Includes second battery, MultiFloor XXL electrobrush, and Hardfloor Care Tool
Product Overview
The Triflex HX3 Plus Aqua is a cordless stick vacuum for shoppers who want one appliance for dry vacuuming and wet hard-floor cleaning. Its AquaTwister attachment adds rotating pads, adjustable water volume, and 360-degree lighting, while the included MultiFloor XXL electrobrush handles general floor cleaning.
Miele's 3-in-1 design lets you change the PowerUnit position for different tasks. Comfort mode is intended for convenient handling, Reach mode places the PowerUnit at the top for flexibility, and Compact mode configures the PowerUnit Solo for quick cleaning or use in tighter areas.
Cleaning controls are managed through the display and three electronic suction levels. FloorDetect adjusts power for the detected flooring, Boost mode adds extra cleaning power for heavily soiled areas, and BrilliantLight on the main electrobrush helps make dust easier to see.
Expert Recommendation
We recommend the HX3 Plus Aqua for households that want cordless convenience plus a dedicated wet-cleaning option for hard floors. The second battery expands the listed low-level runtime, and the included Hardfloor Care Tool gives delicate hard surfaces a separate soft-roller option.
The Aqua model makes the most sense when wet cleaning is important. If you only need dry vacuuming, a Triflex model without the AquaTwister may be a simpler fit, but the supplied facts do not identify a specific alternative model or compare its features. Ace Vacuums can help you review the current Miele lineup and confirm which configuration suits your floors.
Best For
Hardwood Floors
The included Hardfloor Care Tool has a soft woven nylon roller for delicate floors. The AquaTwister adds rotating-pad wet cleaning with adjustable water volume.
Allergy Sufferers
The HEPA lifetime filter is stated to provide 99.999% exhaust air filtration. This makes the filtration system a notable consideration for shoppers focused on captured fine particles.
Large Homes
The package includes a second exchangeable battery, and Miele lists up to 140 minutes of low-level PowerUnit Solo runtime under the stated two-battery conditions.
Apartments
The cordless format avoids a power cord during routine cleaning, while the Compact configuration and free-standing function support quick parking and storage.
Carpet and Rugs
The MultiFloor XXL SEB 436 electrobrush is included for multi-floor cleaning, and FloorDetect adjusts power based on the detected flooring.
Flexible Cleaning
The 3-in-1 design supports Comfort, Reach, and Compact configurations, making it possible to change the machine setup for different cleaning positions and tasks.
Not Ideal For
- It may not be the right choice if you only want a dry vacuum and have no use for the AquaTwister, AquaPads, or cleaning solution.
- The listed high-level runtime with electrical accessories is 2 x 15 minutes, so Boost mode is intended for shorter intensive passes rather than extended whole-home cleaning.
- The 0.5-liter dust container is smaller than the capacity typically associated with many full-size corded vacuums and can require more frequent emptying during larger cleaning jobs.
- The listed recharge time is 240 minutes, so keeping both batteries charged is important for planned longer cleaning sessions.
Key Features
- AquaTwister Wet Cleaning: The AquaTwister uses rotating pads and adjustable water volume to clean hard floors and help remove dried-on dirt.
- 360-Degree Light: Integrated lighting on the AquaTwister brush helps make dirt more visible, including in harder-to-reach areas.
- 3-In-1 Design: The PowerUnit can be positioned for Comfort, Reach, or Compact cleaning configurations.
- FloorDetect Adjustment: FloorDetect recognizes flooring and adjusts power to support cleaning across different floor surfaces.
- HEPA Lifetime Filter: The maintenance-free HEPA lifetime filter provides stated exhaust air filtration of 99.999%.
- Two-Battery Package: The premium set includes an additional exchangeable lithium-ion battery for extended cleaning time.
- Boost Mode: Boost mode provides higher cleaning power for heavily soiled areas.
- Twist2open Emptying: Twist2open helps release dust from the container for convenient emptying.
What Makes This Model Stand Out
The main distinction of this package is the combination of a flexible cordless vacuum and a supplied wet-cleaning attachment. Rather than treating floor washing as an add-on purchase, the set includes the AquaTwister, two AquaPads, a storage tray, and 500 ml of universal cleaning agent.
The premium package also addresses cordless cleaning time with a second battery. Miele lists up to 140 minutes at the low PowerUnit Solo setting, although runtime drops when electrical accessories or the High setting are used. The display helps show remaining time and selected mode while you clean.
Product Comparisons
Triflex HX3 Plus Aqua vs a Dry Cordless Stick Vacuum
The HX3 Plus Aqua includes the tools for both dry vacuuming and wet hard-floor cleaning, including the AquaTwister and AquaPads. A dry cordless stick vacuum may be a better fit for shoppers who do not need wet cleaning, but exact differences depend on the model.
Stick Vacuum vs Canister
The Triflex HX3 Plus Aqua is cordless and can be used in three configurations, which supports quick floor, reach, and compact cleaning. Canister vacuums generally separate the motor and cleaning head with a hose and wand, so they may suit shoppers who prefer a traditional corded format and larger machine body.
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 wet-cleaning capability or a traditional upright approach; an in-store demonstration can help.
Miele vs Dyson
This Miele is a cordless, bagless stick vacuum with a wet-cleaning attachment, HEPA lifetime filter, and two-battery package. Dyson models vary, so compare the exact design, included tools, filtration details, and floor-cleaning functions before choosing.
Questions Buyers Commonly Ask
Is the Triflex HX3 Plus Aqua worth considering?
It is worth considering if you want cordless dry vacuuming and wet hard-floor cleaning in one package. The second battery, HEPA lifetime filter, 3-in-1 design, and included floor tools add practical flexibility.
Is it good for pet hair?
The included MultiFloor XXL electrobrush is intended for multi-floor cleaning, and Boost mode is available for heavily soiled areas. Miele's supplied information does not identify a dedicated pet-hair tool, so pet-focused shoppers should review the included attachments carefully.
Is it quiet?
The listed sound level is 74 dB. Whether that feels quiet depends on the cleaning mode, floorhead, room, and personal expectations.
Can it replace a regular mop?
The AquaTwister provides wet cleaning for hard floors with rotating pads and adjustable water volume. It can add wet cleaning to your routine, although the source does not claim that it replaces every type of traditional mop or floor-care method.
Is it easy to store?
The machine has a free-standing function and a 3-in-1 design, and the package includes a wall mount and storage tray. These features provide several storage and parking options.

Updated September 27, 2026. Request a return for an eligible unused item within 30 calendar days of delivery (or purchase for items collected in store). Eligible returns may be refunded to the original payment method or exchanged, subject to availability. The same 30-day request window applies to both refunds and exchanges; there is no separate seven-day or 15-day refund deadline.
Eligibility and authorization
Items must be unused, clean, complete and in their original packaging with all accessories, manuals and proof of purchase. Contact sales@acevacuums.com or 703-997-9292 before sending anything back. Include your order number, item and reason for return. We will confirm eligibility, charges and return instructions. Unapproved or cash-on-delivery returns are not accepted.
Fees and shipping
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.
