Are the Stratos Upright and the IZ400 the same vacuum?

Effectively yes. Both are Shark Stratos corded uprights with the DuoClean PowerFins HairPro nozzle, a self-cleaning brushroll, a lift-away pod and HEPA filtration. The model numbers differ by market and retailer.

Which is better for pet hair?

Both use the same brushroll, so expect the same result. Owners of both report long hair and pet hair wrapping the second roller, and one IZ400 unit failed on its first day because of pet hair. The self-cleaning brushroll helps but does not eliminate wrap.

No. Both are $264.99 new as of November 3, 2026, at Amazon and Best Buy. Pay extra only for a bundle with more tools, and check what is in the box on each listing.

Which is better on carpet?

They are the same machine, so carpet pickup is identical. Buyers praise the Stratos on carpets and say it makes them feel new again. The roller can stall on thick or uneven surfaces.

How long is the cord?

The IZ400 listing states 30 ft. The Stratos Upright listing does not state a length, and buyers complain the cord is short and not retractable. If cord length matters, take the IZ400 listing at its word.

Is it good for allergies?

Yes. Both have HEPA filtration, and the Stratos Upright adds an Anti-Allergen Complete Seal that traps 99.99% of dust and allergens inside the vacuum. Empty the bin outdoors to limit exposure.

Shark Stratos Upright vs Shark Stratos IZ400

These are the same vacuum under two names: the Shark Stratos upright sold as the Stratos Upright and as the IZ400. Both are $264.99 new as of November 3, 2026, at Amazon and Best Buy respectively, so price does not decide it. Buy whichever store you trust or can get faster; check both listings for the included tools and the odor cartridge. If you have heavy pet hair, read the complaints first, because owners report hair wrapping the second roller.
