Shark Stratos Cordless Vacuum IZ862H Review
Bottom Line
Choose it for strong everyday suction, pet-hair pickup, hard-floor/carpet versatility, and under-furniture reach. Skip it if you need a lighter vacuum, scent-free cleaning, a larger bin, or cordless runtime for long deep cleans.
Best for
Best for pet households and mixed-floor homes that want a cordless vacuum for daily upkeep, large debris, hair pickup, and cleaning under furniture without crouching.
Not for
Not ideal for users who need an ultralight stick vacuum, a scent-free machine, a large dust cup, or long high-power runtime for full-home deep cleans.
Verdict
The Shark Stratos Cordless IZ862H earns broad praise for suction, debris pickup, pet-hair control, sealed filtration, and its MultiFLEX under-furniture reach. Reviewers especially like how it handles hard floors, large debris, hair, and quick daily cleanups, and several lab-style reviews place it near the top of Shark’s cordless lineup. The tradeoff is that the Stratos is not the lightest or simplest cordless vacuum: the floorhead and handle can feel heavy, the odor cartridge divides opinion, and battery life depends heavily on mode and surface. Its bin is also not universally loved. Overall, the evidence supports a premium, feature-rich cordless stick that shines for everyday households and pets, while asking buyers to tolerate weight, scent, and runtime compromises.

Pros highlights
-
Hair-wrap resistance is mostly excellent across real homes and lab-style testing, though one aggressive hair test found a failure.
-
Value is positive but price-sensitive: reviewers call it expensive, yet worthwhile on sale, strong versus Dyson, and good for the money when discounted.
-
Overall opinion is strongly positive across reviews, with awards, recommendations, and high praise, balanced by concerns about weight, runtime, and scent.
-
Reviewers repeatedly found the Stratos powerful, with strong suction and airflow for everyday debris, though one lab-style review said competitors at the price can be stronger.
-
Under-furniture pickup is one of the most consistent strengths, thanks to MultiFLEX and the bending wand reducing crouching and bending.
-
Fine dust pickup is strong overall, including flour, sugar, and super-fine dust results, but one pet-home review noted extra-fine sand could need Boost or extra passes.
Cons highlights
-
Odor control is polarizing: some liked the fresh scent, but others called it gimmicky, strong, or unsuitable for scent-sensitive users.
-
Weight is a repeated weakness, with reviewers calling it hefty, heavier than other models, or heavier than preferred.
-
Accessories are mixed: several reviewers found the included tools useful, but others criticized missing extras, no powered upholstery tool, or an underwhelming dusting brush.
-
Bin feedback is mixed: reviewers liked the decent size or capacity in some homes, but others found it small, frequent to empty, or awkward to clean.

Yes. Multiple reviewers praised pet-hair pickup, hair-wrap resistance, and furniture or upholstery hair cleaning, with one calling it one of the best vacuums for pet hair.
