Our Verdict

Miele Triflex HX1

Dyson V12 Detect Slim

The Dyson V12 Detect Slim is slightly better than the Miele Triflex HX1 for most uses. The Dyson is lighter and easier to store, and it delivers significantly better overall battery life, as it can run for almost twice as long in its most energy-efficient mode while taking much less time to recharge. The Dyson also comes with a wider array of attachments, including a turbo brush that does a better job cleaning pet hair on furniture than the Miele's upholstery tool. However, the Miele feels better built and has a larger-capacity dirt compartment.
