Which is better for pet hair?

The Dyson V12 Detect Slim. Its Motorbar head has polycarbonate vanes that strip hair off the brushroll, and owners praise it for pet hair. The Eureka's anti-tangle brushroll helps, but it has less suction.

Is the Dyson worth the extra $253?

Only if you want the extra suction, the laser dust light and the de-tangling head. At $176.98 the Eureka covers HEPA filtration and a removable battery for far less.

Which has better filtration?

The Dyson is slightly ahead: it is fully sealed and captures 99.99% of particles down to 0.3 microns. The Eureka is HEPA certified and captures over 99.95% of dust and allergens.

Can I swap batteries on either one?

Only on the Eureka. Its lithium-ion battery detaches, so a spare keeps you cleaning past 60 minutes. The Dyson's 7-cell battery is built in and recharges in place.

Which is easier on stairs and in a car?

Both convert to a handheld. The Dyson is the slimmer, lighter package and comes with a mini motorized tool, which suits stairs and car seats well.

Which lasts longer per charge?

Both are rated up to 60 minutes, and both fall well short of that in high-power mode. The Eureka's edge is that you can carry a second battery.
