Miele Triflex HX3 Comparison: Which Cordless Vacuum Is Right for Your Home?
A model-by-model breakdown of the Miele Triflex HX3, Cat & Dog, Plus, Aqua, and Aqua Plus — power, floorheads, battery life, filtration, and price.
If you've been shopping for a premium cordless vacuum, chances are the Miele Triflex HX3 series has landed on your list. Miele's Triflex HX3 lineup is the successor to the popular Triflex HX2, and according to Miele, the HX3 range replaces the HX2 set of vacuums with machines that have longer battery life and a display that shows remaining battery capacity in minutes. With five distinct models — Triflex HX3, Triflex HX3 Cat & Dog, Triflex HX3 Plus, Triflex HX3 Aqua, and Triflex HX3 Aqua Plus — choosing the right cordless stick vacuum for your household can feel overwhelming. This guide breaks down every model in the Triflex HX3 series, comparing power, floorheads, accessories, filtration, and price, so you can decide which Miele cordless vacuum best fits your cleaning needs.
What Makes the Miele Triflex HX3 Series Different?
Every Triflex HX3 vacuum is built around Miele's signature 3-in-1 design, letting you reconfigure the vacuum into three distinct modes — Comfort, Reach, and Compact — for maximum flexibility whether you're cleaning floors, stairs, ceilings, or car interiors. All models share a Digital Efficiency Motor, three standard cleaning power modes (Low, Eco, and High), a HEPA Lifetime filter, self-standing capability in Comfort mode (with the electrobrush attached), automatic FloorDetect technology, and a 74 dB(A) noise level.
Miele also highlights the series' allergy-friendly credentials, noting that the Digital Efficiency Motor works with Vortex Technology to capture 99.99% of dust, making it a suitable choice for allergy sufferers. For households battling everyday messes, every HX3 model also includes a Boost mode for faster cleaning of heavily soiled areas.
Triflex HX3: The Entry-Level Cordless Vacuum
The standard Triflex HX3 (Material No. 12878460) is the most affordable entry point into the series, finished in Brilliant White. It comes equipped with the SEB 430 electrobrush, one battery, and the core accessory kit: a dusting brush, upholstery nozzle, and crevice nozzle. It does not include a headlight on the electrobrush or a hardfloor roller, making it best suited for shoppers who want core Miele cordless performance without extra add-ons. Miele notes that thanks to the battery design, you can vacuum your entire house or large areas without stress thanks to a running time of up to 70 minutes.
Triflex HX3 Cat & Dog: Built for Pet Owners
Finished in Obsidian Black, the Triflex HX3 Cat & Dog (Material No. 12878470) upgrades to the SEB 435 electrobrush with BrilliantLight, Miele's illuminated headlight that reveals hidden dust and pet hair on floors. This model adds the Compact Handheld Brush (HX-EC 10), a motorized attachment purpose-built for lifting pet hair and lint from upholstery and car seats — Miele's own reviewers describe it as a brush specifically designed to help remove pet hair from furniture and vehicle interiors. If shedding cats or dogs are part of your household, this Triflex HX3 configuration is purpose-built for you.
Triflex HX3 Plus: More Power, More Battery Life
The Triflex HX3 Plus (Material No. 12878490) is finished in Titanium PearlFinish and steps things up with two batteries instead of one, effectively doubling runtime for whole-home cleaning sessions. It also includes the SEB 435 electrobrush with BrilliantLight and adds the Hardfloor Roller (HX-HC) for gentle, scratch-free cleaning on hardwood, tile, and laminate floors. For larger homes or multi-story cleaning routines, the extra battery in the Triflex HX3 Plus eliminates the need to pause and recharge mid-clean.
Triflex HX3 Aqua: Vacuum and Mop in One
The Triflex HX3 Aqua (Material No. 12878500) introduces the standout feature of the entire HX3 lineup: the AquaTwister floorhead, which transforms the Triflex HX3 into a hard-floor mop. According to Miele, two rotating pads and a water tank tackle even dried-on dirt, while the 360° Spotlight ensures no stains are missed. The system is refreshingly simple to operate — the Triflex HX3 recognizes the AquaTwister brush automatically and switches from vacuum mode to wet-cleaning mode, letting you choose between three water levels depending on floor type and soil level. Cleanup is just as easy, since you simply remove the pads and wash them in the washing machine once you're finished. The Aqua model ships with one battery, one set of two AquaPads, a 17 fl oz bottle of universal cleaning agent, and a drip tray for the AquaTwister head, but does not include the hardfloor roller.
Triflex HX3 Aqua Plus: The Flagship Model
Sitting at the top of the range, the Triflex HX3 Aqua Plus (Material No. 12878520) combines everything: the AquaTwister wet-cleaning floorhead, the Hardfloor Roller for dry vacuuming, two batteries, two AquaPads sets, and the 360° AquaTwister headlight. This is the vacuum for households that want a single cordless machine capable of both deep dry vacuuming and hard-floor mopping, without compromising on runtime. Notably, Miele designed the AquaTwister to be backward- and forward-compatible across the lineup — the AquaTwister floorhead works with every Triflex HX3 model, and even if you originally choose a model without it, you can upgrade later by purchasing it as a separate accessory.

Cordless Runtime and Charging
Battery life is one of the biggest differentiators in the Triflex HX3 series. Single-battery models like the standard HX3, Cat & Dog, and Aqua offer up to 70 minutes of runtime, while the dual-battery Plus and Aqua Plus models can be swapped mid-clean for continuous use. Miele reports recharging takes around four hours per battery. If your home is on the larger side, the extra battery included in the Plus-tier models is well worth the investment, since it means you're never caught mid-clean with a dead vacuum.
