Miele Triflex HX1 Stick Vacuum

4.1

(10)

Bottom Line

Choose the Triflex HX1 if you want a premium 3-in-1 cordless that shines on carpets and feels unusually versatile; Skip if you prioritize a big bin, light handheld use, or top-tier large-debris and anti-tangle performance.

Best for

Homes with lots of carpet (including pet hair) that want a premium cordless with a true upright/handheld conversion and swappable batteries for longer sessions.

Not for

Anyone who wants a lightweight handheld for frequent above-floor work, hates frequent bin emptying, or needs the best large-debris pickup and anti-tangle brush performance at this price.

Verdict

The Miele Triflex HX1 stands out for its clever 3-in-1 modular design, strong real-world carpet performance, and premium build feel, with multiple reviews praising how it cleans across mixed flooring and how stable it feels in upright/comfort mode. Battery flexibility (removable packs; two-battery bundles on higher trims) is a genuine advantage for larger jobs. The tradeoffs are consistent: the 0.5L bin is small and can be fiddly, handheld use can feel heavy or wrist-straining, and several testers note limitations with larger debris and hair wrap on the standard brush roll. Price is high, so its value depends on whether you’ll actually use the configurability and battery swap ecosystem.

FAQ

How long does the Triflex HX1 run on a charge in real use?

Most reviews cite up to about an hour on low power (often without the powered floorhead), while high/max power commonly lands around the mid-teens to mid-20 minutes depending on configuration and floorhead use.

Is it good for carpets?

Yes. Multiple testers highlight strong deep-clean results on carpet, and the powered floorhead plus surface detection helps it maintain performance on different piles.

Is it good for hard floors?

It can do well on fine debris and edges, but several reviews mention it can push around larger items (like cereal/oats) and it lacks the efficiency boost you’d get from a dedicated soft roller head.

Does it handle pet hair well?

Pickup is generally strong, especially with the Cat & Dog accessories, but hair wrap on the standard brush roll is a recurring complaint for longer strands.

Is the dust bin easy to empty?

Mixed. Some like the hygienic emptying concept, but multiple reviewers describe the 0.5L bin as small and the emptying / filter access as stiff or multi-step.
