The Dyson, because the Submarine head washes hard floors and picks up wet and dry debris. The Miele is dry-only.

Which is better for pet hair?

The Miele Triflex Hx2 Cat & Dog is built for pet hair and has the larger 0.5 L bin. The Dyson's Motorbar head also de-tangles hair, so it is a close call on carpets.

Which has the longer run time?

Both claim up to 60 minutes. The Miele's figure is for the low setting with no accessories, and it drops to about 14 minutes on high with accessories. The Dyson's 60 minutes is its maximum too.

Is the Miele worth the extra money?

Only if you want a removable battery, a bigger bin and a dry-only pet vacuum. At $789.99 against a recent Dyson low of $364.00, the Dyson covers more cleaning jobs for less.

Which is easier to carry?

The Miele, at 3.6 kg (about 7.9 lb) versus 9 lb for the Dyson. The Dyson's extra weight comes partly from its wet-cleaning hardware.

Do both have HEPA filtration?

Yes. Both list HEPA filtration, which helps with fine dust and allergens.
