Which is better for pet hair?

The Dreame Z30. It has 310 AW of suction and ships with a motorized mini-brush and a built-in deshedding tool. The Shark is rated for hair pickup too, but its edge is the dock, not raw power.

Which is better for a large home?

The Dreame Z30, on runtime alone: up to 90 minutes versus 70. The Shark's auto-empty dock saves trips to the trash, but you still stop to recharge after about 70 minutes.

Is the Shark worth it over the Dreame?

Only if the auto-empty dock matters to you. It holds debris up to 45 days and adds odor neutralization, but you pay for that with 18.5 lbs of weight and a 6-hour charge.

Which is easier to carry upstairs?

The Dreame Z30. At 2.2 kg it is roughly a quarter of the Shark's 18.5 lbs, so it is far easier to move between floors.

Do both have HEPA filtration?

Yes. The Dreame rates whole-machine HEPA at 99.99% down to 0.1 µm. The Shark uses a bagless HEPA filter and adds odor neutralization inside the vacuum.

Which lasts longer per charge?

The Dreame Z30, at up to 90 minutes in eco mode against the Shark's 70. Both figures are eco-mode maximums, so expect less in boost.

Dreame Z30 Cordless Stick Vacuum vs Shark PowerDetect Clean & Empty

Pick the Dreame Z30 if you want the strongest suction and the longest runtime in a light 2.2 kg body, and you empty the bin yourself. Pick the Shark PowerDetect Clean & Empty if you would rather never touch dust: its auto-empty dock holds debris up to 45 days, but it weighs 18.5 lbs and charges in 6 hours. The two are close in price at the stores we track, so the deciding factor is the dock, not the cost.
