Shark Stratos Cordless vs Dyson V15 Detect Plus: Lighter Tool or Lower Price?
Both land on the cross-shopping list for the same reason: pet-focused cordless vacuums with an anti-tangle brushroll, sealed HEPA, a dedicated pet tool, and a 60-minute rated ceiling. The Shark Stratos undercuts the Dyson V15 Detect Plus by $320, which is enough to make anyone pause. The question is whether Dyson's lighter build and easier handling justify paying roughly 74% more.
The short answer
Pick the Shark Stratos Cordless (IZ862H) if suction is what you are buying for — 8/10 against 7/10, and it is the cheaper of the two by $320.
Pick the Dyson V15 Detect Plus if handling is what you are buying for — 6/10 against 2/10.

Suction: closer than the badge numbers suggest
Dyson publishes 240 air watts; Shark publishes no suction number at all. That gap looks decisive but isn't measurable, air watts and the kPa figures rival brands quote describe different things, so there's no honest cross-brand comparison to make. Our engine actually scores the Shark's cleaning a notch higher, 8/10 to Dyson's 7/10. The practical read: both pull hard on carpet and bare floors, and the cheaper Shark is not the weaker cleaner here. Suction is not the reason to pay the Dyson premium.
Weight and handling decide this matchup
This is where the money goes. At 6.8 pounds the Dyson is more than two pounds lighter than the 8.9-pound Shark, and the engine's handling scores are lopsided: 6/10 for the Dyson, just 2/10 for the Shark. Numbers that size translate directly into fatigue, carrying the Shark up stairs, holding it overhead for ceiling corners, or detailing a car gets tiring fast. For floor-only cleaning the weight matters less. For a whole-home tool you lift and maneuver constantly, the Dyson is far less punishing.
Runtime, filtration, and price
The rest is close. Both claim 60 minutes, both earn 4/10, because that ceiling is eco mode with a non-motorized tool. On Boost with the powerhead down, expect a small fraction of it, often closer to ten minutes than sixty, from either. Filtration matches: sealed HEPA on both, plus a pet tool and anti-tangle brushroll each. Neither ships with a dock, so both need a wall lean or closet spot. That leaves price as the Shark's argument: $430 against $750, a $320 saving for a vacuum that cleans just as hard.
Choose the Shark Stratos Cordless (IZ862H) if…
- Better suction: 8/10 against 7/10
- Costs $320 less: $430 against $750
Choose the Dyson V15 Detect Plus if…
- Higher overall score: 5.7/10 against 4.7/10
- Better handling: 6/10 against 2/10
Verdict
The Dyson V15 Detect Plus is the better overall vacuum here, 5.7 to 4.7, and it earns that almost entirely on weight and balance, the things that decide whether cleaning stairs and ceilings is bearable. Buy it if you carry your vacuum around the house, do overhead or car detailing, or simply want the lighter tool. Buy the Shark Stratos if you clean mostly at floor level, don't mind an 8.9-pound machine, and would rather keep the $320, its suction gives up nothing.
