Main trade-off
Dyson V12 Detect Slim+
Switch between Fluffy Optic and Motorbar for their intended floor roles.
Head-to-head
Choose V12 Detect Slim+ for an illuminated hard-floor head and particle-count feedback. Choose Stratos IZ862H if you want its wand to bend under furniture and fold for storage while keeping one dual-roller floor head fitted. Both provide automatic suction adjustment.
Before you choose
Both can change power when debris is detected. The useful difference is whether you want a particle-count screen or Shark's simpler indicator and bending wand.
What this is based on
Dyson documents particle-based automatic adjustment. Shark's owner guide documents Clean Sense IQ adjustment and a debris-level indicator.
Main trade-off
Switch between Fluffy Optic and Motorbar for their intended floor roles.
Main trade-off
Its dirt indicator does not provide Dyson's particle-count display.


Compare Dyson V12 Detect Slim+ and Shark Stratos IZ862H for low-furniture reach, floor heads, dust feedback and storage. Both adjust suction automatically.

Winner by situation
MultiFLEX is a hinged wand. Dyson's standard wand is rigid.
The V12 LCD supplies counts. Stratos uses a debris-level indicator.
Both document an automatic dirt-responsive mode.
Stratos folds into its documented storage position.
The maximum-runtime statements do not verify that workload.
What matters in practice
Both can change power when debris is detected. The useful difference is whether you want a particle-count screen or Shark's simpler indicator and bending wand.
Dyson documents particle-based automatic adjustment. Shark's owner guide documents Clean Sense IQ adjustment and a debris-level indicator.
Dyson gives you a dedicated illuminated hard-floor head, while Shark's dual-roller design avoids a head swap for its standard mixed-floor workflow. That is a handling difference, not proof of superior pickup.
Dyson lists two different floor heads. Shark lists two rollers within one DuoClean floor head.
The manual allows removal of the odor cartridge while keeping the dial fitted. You can retain the bending wand without continuing that consumable.
IZ800 guide states the odor dial must remain installed and the cartridge may be removed. Replacement guidance is every six months when the feature is used.

Dyson, 448884-01
A light, button-operated Dyson with a soft roller, particle sensing and a genuinely exchangeable battery.

Shark, IZ862H
A dual-roller Shark with automatic dirt response, a flexible wand and a removable battery rated for longer sessions.
Meaningful differences
| What changes | Dyson V12 Detect Slim+ | Shark Stratos Cordless | Why it matters |
|---|---|---|---|
| Main floor-head setup | Separate Fluffy Optic and Motorbar heads | One DuoClean PowerFins HairPro dual-roller head | Dyson separates the illuminated hard-floor role. Shark combines two rollers in one head. |
| Wand and storage | Rigid wand with wall dock | MultiFLEX bending wand and folded freestanding storage | Shark changes reach and stored shape without removing the wand. |
| Dirt feedback | Particle counts on LCD | Clean Sense IQ debris-level indicator | Both react to dirt. Their feedback formats differ. |
| Odor consumable | No odor cartridge in the reviewed system | Optional odor cartridge, six-month replacement guidance | Shark can run without the cartridge if the required dial remains installed. |
| Battery and maximum runtime | Click-in battery, up to 60 min | Removable battery, up to 60 min in hand-vac Eco | Neither headline promises 60 minutes of automatic mixed-floor cleaning. |
What you give up
Recommendation switch
Choose Shark Stratos Cordless. Stratos supplies both MultiFLEX functions.
Choose Dyson V12 Detect Slim+. V12 supplies its LCD particle readout and Fluffy Optic head.
Choose neither. Both adjust suction, but neither selected package has an auto-empty dock.
What matters in practice
If bending to reach under a bed is the problem you are solving, Stratos has a specific mechanical advantage: the wand hinges. Dyson's dust illumination solves a different problem by making fine hard-floor debris easier to see. Neither feature proves that one vacuum removes more dirt in a shared test.
The V12 has a dedicated Fluffy Optic hard-floor head plus Motorbar. Stratos places a soft roller and PowerFins roller together. For a home with frequent rug-to-hard-floor transitions, think through where spare heads will be stored and whether swapping them is convenient.
Particle counts and dirt indicators are feedback tools, not independent cleanliness certification. Both need maintenance and both can increase power, which changes runtime. A small display is useful only if it helps your actual cleaning routine.
