Main trade-off
Shark Stratos Powered Lift-Away
Requires manual floor-setting selection.
Head-to-head
Choose the Stratos AZ3002 when you want powered floor cleaning with the pod detached and the DuoClean dual-roller head. Choose the SurfaceSense 3418 when automatic floor adjustment and an illuminated crevice tool fit your routine better. Both detach for attachment cleaning, but only the Shark retains powered main-nozzle use with its pod removed.
Before you choose
AZ3002 is the more relevant choice when a powered head must work under a bed after removing the bulky pod. 3418's detachable body is useful for hose tools, but it does not offer that same floor-nozzle configuration.
What this is based on
Exact documentation identifies Powered Lift-Away versus Lift-Off attachment use. No minimum clearance is provided here, so the nozzle still needs to fit the furniture gap.
Main trade-off
Requires manual floor-setting selection.
Main trade-off
No powered detached main-nozzle mode.


Compare Shark Stratos AZ3002 and BISSELL SurfaceSense 3418 for powered under-furniture access, automatic floor changes and exact tools.
The practical choice turns on detached main-nozzle use and floor-head design, then on the constraints in your own setup.
Winner by situation
AZ3002 provides Powered Lift-Away. 3418 detaches for attachment use.
SurfaceSense handles the floor adjustment automatically.
AZ3002 supplies DuoClean with its soft front roller.
3418 includes an LED-lit combination tool.

Exact documentation identifies Powered Lift-Away versus Lift-Off attachment use. No minimum clearance is provided here, so the nozzle still needs to fit the furniture gap.
3418 is convenient when a normal route repeatedly changes floor type, while AZ3002 lets you select its floor setting. The BISSELL still has a carpet-type control, so a sensing feature should not be treated as complete automatic setup.
The 3418 guide separately describes floor sensing and carpet-type adjustment. AZ3002's FAQ describes user-selected modes and reduced roller speed on hard floor.
3418's LED combination tool is useful for checking a narrow gap during attachment cleaning. The AZ3002's floor-head lighting does not establish illumination at the end of its separate crevice tool. Choose the feature that lights the location you actually clean.
Selected package records identify the BISSELL illuminated combination attachment and Shark's standard crevice and upholstery tools. No comparative brightness or dirt-detection result is claimed.

Shark, AZ3002
Powered Lift-Away and a two-roller HairPro floorhead reach under furniture, while the included compact pet brush handles suitable dry fabric.

BISSELL, 3418
A bagless Lift-Off upright that automatically adapts its brushroll to the floor surface. It has a 1 L cup, sealed HEPA filtration and an LED-lit combination tool, with no manual brushroll stop.
Meaningful differences
| What changes | Shark Stratos Powered Lift-Away | BISSELL SurfaceSense Allergen Lift-Off Pet | Why it matters |
|---|---|---|---|
| Detached main-nozzle use | Powered Lift-Away | Lift-Off for hose tools | AZ3002 preserves powered floor-head operation with the pod removed. |
| Floor-head design | DuoClean PowerFins HairPro dual rollers | Single Tangle-Free main roller | The two head designs have different components, without a common pickup test. |
| Floor adjustment | User-selected settings | SurfaceSense automatic adjustment | 3418 automates floor transitions. Carpet suction adjustment still remains. |
| Hard-floor brush behavior | Rollers continue at lower speed | Automatic brush-speed adjustment | Neither row establishes a user-selected brush-off floor mode. |
| Selected narrow-space tool | Crevice tool and separate upholstery tool | LED-lit dusting and crevice combination tool | 3418 specifically lights the attachment's working area. |
What you give up
Recommendation switch
Choose Shark Stratos Powered Lift-Away. AZ3002 supplies that mode with DuoClean.
Choose BISSELL SurfaceSense Allergen Lift-Off Pet. 3418 supplies SurfaceSense and the illuminated combination attachment.
What matters in practice
Both products can detach a body for hose work, but that shared feature can obscure the Shark's different floor configuration. A mattress seam needs an attachment. A dusty carpet area under a bed may call for the main powered head. AZ3002 offers the latter with the pod removed, subject to the actual nozzle clearance.
AZ3002's rollers continue turning more slowly on its hard-floor setting. SurfaceSense adjusts the BISSELL brush automatically. Neither description establishes a selectable suction-only floor setting. If a surface specifically prohibits powered agitation, do not assume a hard-floor label or sensing feature meets that care instruction.
DuoClean, HairPro and SurfaceSense concern the main floor-cleaning system. The small attachments form their own package decision. A lit crevice tool may be useful behind furniture even if the main nozzle has headlights, while the selected Shark package supplies separate upholstery and pet-brush tools. Confirm which attachment will do the recurring job.
