Which is better for pet hair?

Both are sold as pet vacuums with HEPA filtration. The Shark's self-cleaning brushroll does more to prevent hair wrap, while the Dyson's Motorbar head is well proven on carpet. Pick the Shark if long hair tangles are your main problem.

Is the Shark worth the extra money?

At recent lows it costs about $70 more. You get dirt detection, a lighter body and a self-cleaning brushroll. If you mainly need solid suction on carpet and hard floor, the Dyson covers that for less.

Which is easier to carry upstairs?

The Shark. At 24 oz it is far lighter than the Dyson V10, which weighs about 5.5 lb with the wand and head attached.

Do both have HEPA filters?

Yes. Both list HEPA filtration and bagless bins. The Dyson adds whole-machine filtration, which captures particles before they reach the motor.

Which has the bigger dustbin?

The Dyson, but only slightly: 0.2 gal versus 0.19 gal. Expect to empty either one several times during a whole-house clean.

How have prices moved recently?

The Shark ranged from $279.99 on November 2 to $329.95 on November 5. The Dyson ranged from $349.99 on November 2 down to $210.00 on November 5, a much wider swing.

Shark PowerDetect Cordless Vacuum vs Dyson V10 Animal + Cordless Vacuum

The Dyson V10 Animal + is the better value right now: it hit $210.00 on November 5, well below the Shark PowerDetect's low of $279.99 on November 2. The Shark has a stronger feature set for pet hair and edge cleaning, but you pay about $70 more for it at current lows. Buy the Dyson if price and proven cleaning performance matter most; buy the Shark if you want the newest detection tech and a lighter stick.
