Which is better for pet hair?

The Shark has two brushrolls and a tangle-resistant design aimed at hair pickup, and it is marketed for pets. The Dyson's All Floor Cones head is also built to detangle all hair lengths. Both work; the Shark's second roller gives it an edge on edges and upholstery.

Which has better filtration?

The Dyson publishes a sealed five-stage whole-machine HEPA claim of 99.99% of particles down to 0.1 microns. The Shark has HEPA filtration with a sealed system but does not publish an equivalent particle figure. The Dyson is the safer pick for allergy households.

Is the Shark worth the extra money?

Only if its price is close to the Dyson's. The Shark adds auto suction boost, floor detection and a bending wand. At the Dyson's recent low of $65.77 (November 5) versus the Shark's $159.66 (November 1), the Dyson is clearly the better value.

Which is easier to carry and store?

The Dyson is 1 lb lighter at 6 lb. The Shark's MultiFLEX wand folds for compact storage and bends to reach under furniture, which the Dyson's fixed wand cannot do.

How long does each run on a charge?

Dyson claims up to 60 minutes and Shark claims up to 70, both on the lowest power setting. Expect far less on maximum suction from either.

Which has more reliable reviews?

The Dyson's 4.5 comes from 7,300 ratings; the Shark's 4.7 comes from just 33. The Dyson's score is far more statistically solid.

Dyson V10 Konical Cordless Vacuum vs Shark PowerDetect Speed Cordless Stick Vacuum

Both are cordless stick vacuums with HEPA filtration and around an hour of run time, but they trade off differently. The Dyson V10 Konical is the proven pick: 150 air watts, a 6 lb body, whole-machine HEPA and a huge review base. The Shark PowerDetect Speed adds dirt and floor detection, a second brushroll and a MultiFLEX wand, but its 4.7 rating rests on only 33 reviews. On price, the Dyson has been seen as low as $65.77 (November 5) and as high as $399.95 (November 3); the Shark has ranged from $159.66 (November 1) to $329.95 (November 3). Buy whichever sits near its low, and check the price history before you commit.
