Which is better for pet hair?

The Dyson V8 Absolute ships with a Motorbar head and a Hair screw tool built for pet beds and upholstery. The Shark lists hair pickup as its top use case and adds a wider 10.19 in path. Both handle pet hair; pick the Dyson if you clean couches and cars, the Shark if you want long carpet runs.

Which has longer runtime?

The Shark, at 70 minutes versus 40 minutes for the Dyson. The Dyson's 40 minutes is fade-free, but the gap is large enough to matter in a big home.

Do I have to empty the dust cup by hand?

On the Dyson, yes: the 0.14 gal cup is small and you empty it yourself. The Shark's dock empties the cup automatically after each use.

Is the Shark worth the extra money?

At the recent prices, yes if you want the auto-empty dock and 70 minutes. The Dyson's lowest recent daily price of $25.99 on October 29, 2026 was far below the Shark's $259.99 on November 2, 2026, so compare live prices before buying.

Which is easier to carry and store?

The Dyson at 6 lb converts to a handheld and hangs on a simple docking station. The Shark is a full stick with a bulky auto-empty dock, so it needs floor space.

Can I replace the battery?

The Dyson V8 uses a removable 2800 mAh battery, so you can swap in a spare. The Shark's battery is non-detachable and takes 6 hours to charge.
