The catch
Dyson V12 Detect Slim+
Swap between Fluffy Optic and Motorbar to suit the floor roles they were made for.
Side by side
Dyson V12 Detect Slim+ vs Shark Stratos IZ862H: Dyson lights hard-floor dust, Shark bends below furniture
Quick verdict
V12 Detect Slim+ is the choice for an illuminated hard-floor head and particle-count feedback. Stratos IZ862H is the choice if you want a wand that bends under furniture and folds for storage, with one dual-roller floor head left fitted. Automatic suction adjustment comes with both.
Before you buy
Why, and what it costs you
Automatic suction is not what settles this pair
Each can change power when it detects debris. What sets them apart is whether you want a particle-count screen or Shark's simpler indicator and bending wand.
Where this comes from
Particle-based automatic adjustment is documented for Dyson. Shark's owner guide documents Clean Sense IQ adjustment and a debris-level indicator.
The catch
Shark Stratos Cordless
Dyson's particle-count display is not something its dirt indicator offers.
Dyson V12 Detect Slim+
- Why pick it
- Let the Fluffy Optic head show up hard-floor dust
- Read particle-count feedback on the LCD
- The catch
- Swap between Fluffy Optic and Motorbar to suit the floor roles they were made for.
Shark Stratos Cordless
- Why pick it
- Bend the wand under low furniture and fold it away for storage
- Leave the DuoClean dual-roller head on across mixed floors
- The catch
- Dyson's particle-count display is not something its dirt indicator offers.

What this page compares
Dyson V12 Detect Slim+ vs Shark Stratos IZ862H comes down to low-furniture reach, floor heads, dust feedback and storage, and both adjust suction automatically.

I need a wand that can bend to get under furniture
A hinged wand is what MultiFLEX is, while Dyson's standard wand is rigid.

I want the vacuum's display to show particle counts
Counts come from the V12 LCD, whereas Stratos uses a debris-level indicator.

In practice
Differences you will notice
Automatic suction is not what settles this pair
Each can change power when it detects debris. What sets them apart is whether you want a particle-count screen or Shark's simpler indicator and bending wand.
How we worked this out
Particle-based automatic adjustment is documented for Dyson. Shark's owner guide documents Clean Sense IQ adjustment and a debris-level indicator.
Choosing a head involves a trade-off on a mixed-floor route
With Dyson you get a dedicated illuminated hard-floor head, and Shark's dual-roller design spares you a head swap in its standard mixed-floor workflow. That is a difference in handling and no proof of superior pickup.
How we worked this out
Two different floor heads are listed for Dyson. For Shark, the listing is two rollers inside one DuoClean floor head.
Wanting to avoid fragrance does not automatically exclude Stratos
According to the manual, the odor cartridge can be taken out while the dial stays fitted. You can keep the bending wand and stop using that consumable.
How we worked this out
The IZ800 guide says the odor dial has to stay installed and that the cartridge may be removed. When the feature is used, the guidance is to replace the cartridge every six months.

Dyson, 448884-01
V12 Detect Slim+
A light Dyson with button controls, a soft roller, particle sensing and a battery you can swap out.

Facts we checked
- Main floor-head setup: Separate Fluffy Optic and Motorbar heads
- Wand and storage: Rigid wand with wall dock
- Dirt feedback: Particle counts on LCD
- Odor consumable: No odor cartridge in the reviewed system
Option B
Shark, IZ862H
Stratos Cordless
This dual-roller Shark responds automatically to dirt, has a flexible wand and comes with a removable battery rated for longer sessions.
- Best for
- Mixed floors with a lot of hair, if a stronger head design matters more to you than low carried weight
Facts we checked
- Main floor-head setup: One DuoClean PowerFins HairPro dual-roller head
- Wand and storage: MultiFLEX bending wand and folded freestanding storage
- Dirt feedback: Clean Sense IQ debris-level indicator
- Odor consumable: Optional odor cartridge, six-month replacement guidance
Spec by spec
Where they really differ
| Spec | Dyson V12 Detect Slim+ | Shark Stratos Cordless | In practice |
|---|---|---|---|
| Main floor-head setup | Separate Fluffy Optic and Motorbar heads | One DuoClean PowerFins HairPro dual-roller head | Dyson handles the illuminated hard-floor role with its own head. Shark puts two rollers in one head. |
| Wand and storage | Rigid wand with wall dock | MultiFLEX bending wand and folded freestanding storage | Reach and stored shape change on Shark with no need to remove the wand. |
| Dirt feedback | Particle counts on LCD | Clean Sense IQ debris-level indicator | Each reacts to dirt, but the feedback is presented differently. |
| Odor consumable | No odor cartridge in the reviewed system | Optional odor cartridge, six-month replacement guidance | As long as the required dial stays installed, Shark can run without the cartridge. |
| Battery and maximum runtime | Click-in battery, up to 60 min | Removable battery, up to 60 min in hand-vac Eco | A promise of 60 minutes of automatic mixed-floor cleaning is not made by either headline. |
Trade-offs
What each pick costs you
With Dyson V12 Detect Slim+
- Shark's hinged reach and folded freestanding storage are not something the rigid wand provides.
With Shark Stratos Cordless
- If you keep using the odor feature, it brings a consumable with it.
Change of plan
When the answer changes
A bending wand and folded floor storage are both required
Go with Shark Stratos Cordless. Both MultiFLEX functions come with Stratos.
What matters most is particle counts and lit-up hard-floor inspection
Go with Dyson V12 Detect Slim+. V12 comes with its LCD particle readout and Fluffy Optic head.
I need suction that adjusts itself and a bin that empties itself
Neither model fits. Suction adjustment is on both, but neither selected package comes with an auto-empty dock.
Decision guide
How to decide
Go with V12 Detect Slim+ for an illuminated hard-floor head and particle-count feedback. Go with Stratos IZ862H for a wand that bends under furniture and folds for storage, with one dual-roller floor head staying fitted. Both adjust suction automatically.
Settle the under-furniture workflow first
If the problem you are solving is bending down to reach under a bed, Stratos has a specific mechanical advantage in its hinged wand. Dyson's dust illumination tackles a different problem by making fine hard-floor debris easier to see. Neither feature proves that one vacuum removes more dirt than the other in a shared test.
Decide whether you will swap cleaner heads
V12 comes with a dedicated Fluffy Optic hard-floor head as well as Motorbar, whereas Stratos puts a soft roller and a PowerFins roller together. If your home has frequent transitions between rugs and hard floors, think about where spare heads would be stored and whether swapping them is convenient.
Put the smart displays in perspective
Particle counts and dirt indicators give you feedback and do not amount to independent cleanliness certification. Both vacuums need maintenance, and both can raise power, which changes runtime. A small display is only useful if it helps your actual cleaning routine.
What this page can’t tell you
- No matched test of pickup, noise, handling or automatic-mode runtime was carried out. The two 60-minute maximums do not come from an equal workload.
