Shark Stratos Cordless (IZ862H)
The Shark Stratos is a mid-priced ($430) cordless stick vacuum whose main argument is deep-cleaning suction: it scores among the strongest we test, matching machines that cost twice as much, and pairs that with fully sealed HEPA filtration. Shark doesn't publish a suction figure, so that rating comes from cleaning tests, not a spec sheet. The catch is weight: at 8.9 lb it is the heaviest cordless in our catalog, and much of its trouble flows from there.

Habilytics Score
Shark doesn't publish an Air Watt or kPa number for the Stratos, so this rating comes from our cleaning tests rather than a spec sheet - and in those tests it lifts embedded carpet dirt with the strongest cordless machines we measure. Remember that even where rivals do print a figure, Dyson's Air Watts and most brands' kPa measure different things and can't be compared directly, so cross-brand suction claims mean little on paper.
The 60-minute rating is a best case: eco mode paired with a non-motorized tool. Switch to the motorized brushroll for carpet or Boost for ground-in pet hair and usable time falls to a fraction of that - typical for a single-battery cordless, but far short of the 120-minute LG CordZero.
At 8.9 lb the Stratos is the heaviest cordless in our catalog, and the mass sits high near the motor and bin instead of down in the hand. That makes it genuinely tiring to hold overhead or carry on stairs and awkward to steer one-handed under furniture - the weakest part of the package by a wide margin.

Where it wins: suction and sealed filtration
The Stratos earns its keep on deep cleaning. Its suction rating matches the Dyson Gen5outsize and Shark's own PowerDetect, both machines at the top of our suction tier, and it holds that power on carpet where lighter vacuums fade. The filtration is genuinely sealed HEPA, so fine dust and allergens leave through the filter rather than gaps in the body, which matters in pet and allergy homes. A dedicated pet tool and anti-tangle brushroll round out a capable cleaning package. On cleaning performance alone, little at this price beats it.
The trade-off: it's heavy, and you'll feel it
That cleaning power comes in the heaviest body we've weighed: 8.9 lb, noticeably more than the 5.9 lb LG CordZero or the 6.8 lb Dyson V15. Cordless vacuums are held, not pushed, so that weight lands in your wrist and shoulder; on stairs, under furniture, and for overhead cobwebs it tires you out fast. It also ships with no dock, so there's no charging cradle or auto-empty base to offset the bulk - you lean it in a closet and lift the whole machine every time. If much of your cleaning is overhead or across floors, this is the wrong tool.
Value at $430
At $430 you're paying mid-tier money for top-tier suction and accepting a bottom-tier body. The catch is the LG CordZero A925: it costs $30 less yet scores far higher overall, with the same sealed HEPA and pet tools but 3 lb less weight and double the rated runtime. Even Shark's own PowerDetect adds an auto-empty dock for about $40 more. The Stratos makes sense only if raw suction outranks everything else for you and the weight genuinely doesn't bother you - otherwise the money buys a better all-rounder.
Who it's for / who it's not
Who it's for
- You want top-tier deep-carpet and embedded-dirt suction and rank it above everything else
- Pet or allergy households wanting genuinely sealed HEPA plus a dedicated pet tool
- Single-floor homes where the vacuum rarely leaves ground level
- Stronger users who won't be bothered by an 8.9 lb machine during a full clean
Who it's not for
- Anyone who regularly cleans stairs, ceilings, or lifts the vacuum overhead - at 8.9 lb it's the heaviest we tested
- Buyers counting on long runtime; the 60-minute max is eco mode and drops sharply on Boost
- Smaller or less strong users, or anyone prone to wrist and shoulder fatigue
- Shoppers who want a charging dock or auto-empty base - the Stratos ships with neither
- Value shoppers, since the lighter LG CordZero A925 outscores it for $30 less
Alternatives in our catalog
Dyson V15 Detect Plus — $750
Choose the Dyson V15 Detect Plus if you want comparable deep-cleaning suction in a far more manageable 6.8 lb body and can spend roughly $320 more, though its published 240 AW can't be compared directly to Shark's unpublished figure and its 60-minute max runtime is no better.
