Triflex HX3 vs Duoflex HX1 Key Specs
Cleaning need
Edge: Miele Triflex HX3 Cordless Vacuum
The Triflex HX3 is explicitly designed for hard floors, featuring a dedicated brush roll that glides smoothly to protect delicate surfaces while ensuring thorough cleaning. It also includes a MultiFloor Brush with automatic floor detection for carpets. The Duoflex HX1 Extra takes a different approach, focusing on quick cleanups with an Intelligent Multifloor Electrobrush that adjusts power automatically. It also comes with a flexible Universal Brush for sensitive surfaces. If you primarily clean hard floors, the Triflex HX3 offers specialized tools for that specific task, whereas the Duoflex HX1 is built for versatile, rapid tidying across mixed surfaces.
Runtime
Edge: Miele Triflex HX3 Cordless Vacuum
Battery life is a major differentiator between these two models. The Triflex HX3 offers a maximum runtime of up to 70 minutes on a single charge. This is supported by a Smart Digital Display that informs you of the remaining runtime, battery level, and power mode. In contrast, the Duoflex HX1 Extra provides up to 55 minutes of running time. Its battery level is shown via a simple LED indicator. The Triflex HX3 gives you 15 minutes of extra cleaning time, which can be significant for larger homes or when you want to avoid interruptions for recharging.
Weight and size
Edge: Miele Duoflex HX1 Extra Lightweight Stick Vacuum
Portability and maneuverability depend heavily on weight and dimensions. The Duoflex HX1 Extra is significantly lighter at 6.9 pounds, making it easy to carry up stairs or store in tight spaces. It is also more compact, with a height of 29.9 inches and a width of 7.6 inches. The Triflex HX3 weighs 8 pounds and stands 51.1 inches tall with a width of 10.3 inches. While still manageable, the Triflex HX3 is bulkier. If you frequently move the vacuum between floors or need a compact profile, the Duoflex HX1 Extra is the more practical choice due to its lighter build and smaller footprint.
Filtration
Edge: Tie
Both vacuums prioritize air quality and allergen control, but they use different filtration systems. The Triflex HX3 features a HEPA Lifetime Filter and a sealed dust container to keep dust contained during cleaning and emptying. The Duoflex HX1 Extra uses a hygiene filter that captures 99.99% of particles, including fine dust and allergens, in accordance with IEC 62885-4 standards. Both systems are effective for maintaining a healthy home environment. The Triflex HX3 highlights the lifetime aspect of its HEPA filter, while the Duoflex HX1 Extra emphasizes its high percentage of particle capture. For most users, both provide excellent filtration performance.

The Triflex HX3 boasts an LED headlight on its MultiFloor Brush and automatic floor detection, which helps you see debris and adjusts suction based on the surface. It also self-stands, allowing for convenient parking. The Duoflex HX1 Extra focuses on flexibility, with a design that goes flat to the floor for under-couch cleaning and up to top shelves.
