Which is better for allergies?

The Eureka. Its HEPA filter with Complete Seal claims over 99.95% capture of dust and allergens, and it is HEPA certified. The Shark uses foam filtration with an anti-allergen seal but is not HEPA certified.

Which has longer runtime?

The Eureka, up to 60 minutes versus up to 40 minutes for the Shark. The Eureka's battery also detaches, so a spare pack extends cleaning time.

Is the Shark worth the extra money?

It is only about $2 more at current prices. You pay for lighter weight, a bigger hands-off dust cup and a 5-year warranty, and give up suction, runtime and HEPA filtration.

Which is better on carpet?

Both clean carpet and hard floors. The Eureka has higher stated suction and floor-sensing brushroll speed; the Shark's brushroll and 10.6-inch path suit pet hair on carpet.

The Shark publishes a 5-year warranty; Eureka does not state one. The Eureka's removable battery is easier to replace when it wears out.

Which is easier to carry?

The Shark, at 7.5 lbs. Eureka does not publish a weight for the 440.
