Which is better for pet hair?

The Dyson V8 Absolute. It ships with a de-tangling Motorbar head and a hair screw tool built for pet beds and upholstery, and its whole-machine filtration captures pet allergens.

Which has the bigger dust bin?

The Dreame Z20 at 0.16 gal versus 0.14 gal for the V8 Absolute. The difference is small; both need emptying often on big jobs.

Is the Dreame Z20 worth the extra money?

Only if you value the larger bin and newer design. The V8 Absolute has far more ratings, published run time and filtration, and a 2-year warranty, and it has sold for less.

The V8 Absolute is the safer bet. It has a 2-year warranty, lifetime Dyson support and a large owner base; the Z20 has too few ratings to judge long-term durability.

Can the Dyson V8 Absolute clean hard floors and carpets?

Yes. It includes the Fluffy head for hard floors and the Motorbar head for carpets, so you swap heads rather than buying extras.

How long does the V8 Absolute run on a charge?

Up to 40 minutes of fade-free cleaning, less in Boost mode and depending on floor type and attachments.

Dyson V8 Absolute vs Dreame Z20 Cordless Stick Vacuum

Buy the Dyson V8 Absolute if you want a proven stick vacuum with two cleaner heads, a pet-hair tool and a long parts and support record. Buy the Dreame Z20 if you want a newer design with a larger bin and are willing to take a chance on a brand with few ratings. On price, the V8 Absolute has swung from $25.99 to $179.99 since October 29, while the Z20 has run $239.99 to $297.39 since November 2, so the Dyson is usually the cheaper buy.
