Shark Stratos Cordless Vacuum IZ862H

4.2

Bottom Line

Choose the Shark Stratos IZ862H if you want top-tier pickup on hard floors and carpets with smart auto-boost and easy under-furniture reach. Skip if you are sensitive to strong scent cartridges or want a lighter, longer-running cordless for deep-clean marathons.

Best for

Busy homes with pets and mixed flooring that want strong pickup plus a sensor-driven mode that adjusts power automatically, especially if you will use the folding wand to reach under beds and sofas.

Not for

Anyone who prioritizes the lightest possible stick vacuum for lots of stairs, needs long runtime on max power, or strongly dislikes scented add-ons in a vacuum.

Verdict

Across review sources, the Shark Stratos IZ862H is repeatedly positioned as a high-performing cordless stick with a two-roller floorhead that keeps debris moving from smooth floors to carpeting, and with notably good dust containment from its sealed HEPA-style filtration. Hair handling is a consistent highlight for pet owners, with most testers seeing minimal wrap. The tradeoff is comfort: the unit is heavier than many cordless rivals and can feel bulky around tight gaps, and the highest power setting shortens runtime significantly. The odor neutralizer can be too strong for scent-sensitive households, and the dust cup may take extra rinsing after fine powders.

Multiple reviews emphasize a sealed, HEPA-style filtration system and strong dust containment, including smoke-style tests and praise for reduced dust blowback.

Large debris pickup is consistently strong with little scatter reported, handling cereal, rice puffs, and other chunky messes well.
Cordless convenience 4.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.7

Cordless operation is repeatedly praised for quick daily cleanups and easier movement around furniture and stairs; the main limiter is how quickly runtime drops in higher modes.
Crevice / Groove Pickup (Hard Floors) 4.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.7

Crevice and groove cleaning is strong in multiple tests, supported by good head sealing and effective crevice tools.
Ease of use 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.6

Ease of use is broadly praised for intuitive controls and smooth cleaning on mixed floors, with the main caveat being fatigue from the unit's weight during longer sessions.
Comparative performance 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.6

In comparisons, it is often positioned as competitive with top cordless models and has won category awards in some sources; a few reviewers still say other models may offer better value depending on sales and feature priorities.

Durability impressions are positive in hands-on use, with reports of the body surviving bumps and feeling well built, although the overall unit is heavy.
Packaging quality 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.6

At least one hands-on review calls the packaging minimal and largely recyclable, with little unnecessary filler.
Hard Floor — Fine Dust Pickup 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.6

Fine-dust pickup on hard floors is a standout strength in many tests, though ultra-fine sand or sugar may need an extra pass or a higher power setting.
Assembly and Setup 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.6

Assembly is typically fast and intuitive, with most reviewers set up in minutes; occasional fiddly steps are tied to the scent cartridge and its dial.

Pet owners consistently report strong hair pickup on floors and furniture, making it a reliable choice for routine pet messes.
Suction & Airflow 4.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 9 reviews 4.5

Most reviewers describe suction as genuinely strong for a cordless stick, with some tests measuring class-leading numbers for Shark. A few sources note it is not the absolute strongest versus premium competitors, and power use rises quickly in high modes.
Dried-On Stain Removal 4.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.5

Steering and handling are commonly described as smooth and responsive with good swivel, though the head can feel bulky in tight gaps.
Edge & Baseboard Cleaning (Hard Floors) 4.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.5

Edge and baseboard performance is repeatedly described as very good, helped by strong sealing at the floorhead.
Versatility 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.4

Versatility is a strength: it works across mixed floors, folds for storage, and converts to handheld for above-floor tasks. It is not a wet/dry or self-empty system, so it stays focused on vacuuming.
Low-profile design 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.4

Despite a bulky head overall, several reviewers note it can still get under some cabinets or low furniture when paired with the flexible wand.
Hair‑Wrap / Tangle Resistance 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 10 reviews 4.4

Most reviews say hair wrap is minimal thanks to a self-cleaning brushroll design, though one stress test still reported tangling under heavy hair conditions.
Headlight & LED lights 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.4

LED headlights are frequently mentioned as helpful for spotting dust; a few sources differ on whether a headlight is included in specs, but hands-on reviews generally report usable LEDs.

Controls and the LED display are widely liked, with clear mode changes plus battery and sensor feedback that are easy to read while cleaning.
Support & Reliability 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.3

A longer warranty period is a recurring highlight, though some reviewers still recommend buying with coverage because repairability can be a concern for cordless sticks in general.
Carpet — Medium-Pile Pickup 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.3

Carpet cleaning is often rated very good to excellent, including deep-clean style tests. One lab-style review found only average per-pass pickup versus top competitors, so expectations should be calibrated to mode and carpet type.
Floorhead design 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.3

The DuoClean two-roller, power-fin style floorhead earns frequent praise for smooth transitions and strong pickup, but its bulk can make narrow reach harder.
AI, Smart & App / Automation 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 10 reviews 4.3

Clean Sense IQ dirt sensing that automatically adjusts suction is generally viewed as useful, though at least one reviewer felt the boost was subtle aside from added noise.
Upholstery / Above-Floor Pickup 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.2

Above-floor cleaning is generally effective on upholstery and tight spots, but multiple sources note the lack of a powered upholstery tool in the box.
Storage footprint & upright-stand stability 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.2

The MultiFLEX hinge lets the vacuum fold down for compact, often freestanding storage. A minority of reviewers note it may not stand fully upright as securely as a docked unit.
Convertible handheld design 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.2

Detaching to a handheld configuration is useful for stairs, furniture, and cars, but several reviewers note it can feel a bit heavy in the hand for extended above-floor work.

Swapping attachments and switching into handheld mode is generally quick and straightforward, which helps for spot-cleaning and tight spaces.
Runtime (Measured, Default) 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 9 reviews 4.1

Eco runtimes around an hour are frequently cited, while sensor/auto modes are commonly closer to the 20–30 minute range depending on surface and usage.
Maintenance requirements 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.1

Maintenance is usually described as low effort due to washable filters and reduced hair wrap; cleaning the dust cup after fine powders can be the most annoying routine task.
Battery & Charging 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.9

Charging times are typically around 3 to 4.5 hours, and the removable battery is a plus. Some reviewers report performance is more consistent when the battery is kept fully charged or when a second battery is available.
Price & Value 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 3.9

Value perceptions hinge on price: at full MSRP it is often labeled expensive, but it is frequently viewed as a strong buy when discounted, especially versus premium cordless rivals.
Emptying & Mess Control 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 3.9

Emptying is typically one-button and low-mess, but fine powders can stick inside the bin and require rinsing for a truly clean cup.
Accessories & Tools 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 3.8

Included tools usually cover basics like a crevice/duster tool and an anti-allergen brush. Several reviewers wish it bundled more (powered upholstery tool, extra filters, or a dedicated pet tool depending on region).
Bin & Bag 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 3.7

Bin size feels acceptable for many whole-home cleans, but some reviewers find it small or awkwardly shaped, especially when dealing with fine powders that cling to the interior.
Runtime (Measured, Boost/Turbo) 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.7

Boost or Max runtime is short in testing (around 10–11 minutes), which is typical for high-power cordless sticks.
Noise level 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.6

Noise is reasonable in Eco/auto modes in at least one measurement, but it becomes noticeably loud in Boost and when the dirt sensor ramps power.
Ongoing ownership costs (bags, filters, batteries) 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.6

Beyond filters and batteries, the optional scent cartridges can add a small recurring cost, and some reviewers wish spare filters were included for the price.
Stair Cleaning 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.6

Stair cleaning is doable, especially in handheld mode, but several reviewers call out the head weight as tiring when doing stairs with the full unit.
Odor control 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 10 reviews 3.6

The odor-neutralizer cartridge is polarizing: some love the fresh scent while others find it too strong or unnecessary. It can also introduce ongoing cartridge costs.

Cons

Area Rug Handling 3.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.4

Area rugs are usually handled well, but thin or lightweight rugs can get pulled toward the head unless suction is reduced.
Weight 3.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 3.3

Weight is the most common ergonomic complaint, with many calling it heavier than peers and sometimes top- or head-heavy, especially on stairs.
Stuck resistance 3.2 ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.2

A few users note the brush can grab small objects like cords or fabric if you are not careful, but these clogs are usually easy to clear without damage.

FAQ

How long does the battery last in real use?

Reviews commonly cite up to about an hour in Eco, but sensor-driven modes are often closer to 20–30 minutes. Max/Boost runtimes are much shorter (around 10–11 minutes in some tests), and at least one reviewer reported shorter sessions if the battery was not fully charged.

Does Clean Sense IQ really change suction?

Most reviews describe the dirt sensor increasing suction when it detects debris and then dropping back down when the area is clean. One reviewer said the boost felt subtle and was more noticeable as increased noise than a dramatic cleaning change.

Is it good for pet hair and long hair?

Across sources, hair pickup is repeatedly strong and the anti-hair-wrap brushroll reduces tangles for most households. One stress test still reported tangling, so very long hair or heavy shedding can occasionally overwhelm the system.

What is the odor neutralizer like, and can you avoid it?

The scent cartridge is love-it-or-hate-it: some people enjoy the fresh smell while others find it too strong or gimmicky. Several reviews indicate it is optional or removable, and replacement cartridges can add a small ongoing cost.

Will it fit under furniture and store easily?

The MultiFLEX wand is widely praised for cleaning under low furniture and folding down for compact storage. Upright stability varies by how it is folded and where it is placed, and it may not feel as stable as a docked charging stand.
