Which is better for pet hair?

The Dreame L40 Ultra Gen 2 has 25,000Pa suction and an extending brush for edges, which suits pet hair on carpet and along walls. The Shark handles pet hair too, but its suction is not published, so the Dreame is the safer pick on raw power.

Which is better for allergies?

The Shark PowerDetect Never Touch Pro is HEPA certified with a post-motor HEPA filter, which is the clearer choice for allergy households. The Dreame does not claim HEPA filtration.

Is the Dreame worth the savings over the Shark?

Yes for most shoppers. At $499.98 versus $549.95, the Dreame costs less and adds stronger suction, longer runtime and a longer self-empty interval. Pay the extra for the Shark only if HEPA filtration is a must.

Which lasts longer between emptyings?

The Dreame, at up to 100 days with its 3.2L bag. The Shark's base holds up to 60 days.

Do either need extra purchases?

The Dreame's automatic cleaning solution filling needs a separately bought module. The Shark's listed kit needs no add-on for basic self-emptying.

Which is better for large homes?

The Dreame, with up to 231 minutes of quiet-mode runtime and multi-floor mapping. The Shark runs up to 120 minutes per charge.
