Head-to-head
Shark PowerDetect AZ4002 vs Hoover UH72625: Shark automates floor response, Hoover gives manual height and brush control
The short answer
Choose the Shark AZ4002 when you want automatic floor, dirt, edge and direction response plus Powered Lift-Away. Choose the Hoover UH72625 when manual nozzle-height selection and explicit brush shutoff are more important. Both collect dirt in a cup and include fabric tools, so the useful distinction is how their floor heads are controlled and configured.
Before you choose
The reasoning and the trade-offs
Automatic response and direct overrides are different priorities
AZ4002 is the stronger candidate when you want the machine to respond to detected dirt, edges and floor changes. UH72625 is the clearer candidate when a selected nozzle height or explicitly stopped floor brush is a nonnegotiable requirement.
What this is based on
Exact model evidence identifies Shark's sensing features and Hoover's height dial and shutoff pedal. No claim is made that sensing supplies every manual control or guarantees surface compatibility.

About this comparison
Compare Shark PowerDetect AZ4002 and Hoover UH72625 for automatic controls, powered detached cleaning, manual nozzle height and brush shutoff.
The practical choice turns on floor response and detached floor-head use, then on the constraints in your own setup.

What matters in practice
The differences that matter
Automatic response and direct overrides are different priorities
AZ4002 is the stronger candidate when you want the machine to respond to detected dirt, edges and floor changes. UH72625 is the clearer candidate when a selected nozzle height or explicitly stopped floor brush is a nonnegotiable requirement.
How we reached this conclusion
Exact model evidence identifies Shark's sensing features and Hoover's height dial and shutoff pedal. No claim is made that sensing supplies every manual control or guarantees surface compatibility.
Powered Lift-Away changes a cleaning configuration, not just carrying
AZ4002 can remove its pod from the path while the main floor head remains powered. Hoover's fixed upright instead uses hose tools for hard-to-reach locations. This is a meaningful distinction when the job is floor cleaning beneath furniture.
How we reached this conclusion
The selected AZ4002 documents Powered Lift-Away. Hoover's manual shows fixed-upright hose use. No measured clearance, handling force or minimum furniture height is available.
Hair management reduces one service task while other work remains
AZ4002's self-cleaning main brush is relevant if wrapped hair repeatedly sends you to the underside of a conventional head. Hoover's manual describes removing six bottom-plate screws to access that area. This does not establish maintenance-free use for Shark.
How we reached this conclusion
Hoover's exact linked guide gives the six-screw brush-access sequence. AZ4002 documents self-cleaning at the main roller, while both remain bagless machines requiring ordinary care.
Choice A
Shark, AZ4002
PowerDetect Powered Lift-Away
Four sensing functions adjust floor cleaning, and Powered Lift-Away keeps the dual-roller floorhead usable with the pod detached.
- Best matched use
- You want automatic suction and brush-speed adjustment.
Checked facts
- Floor response: Floor, dirt, edge and direction detection
- Detached floor-head use: Powered Lift-Away
- Floor-nozzle height: No manual height dial established here
- Brush-off floor mode: No manual suction-only mode established here
Choice B
Hoover, UH72625
WindTunnel 3 Max Performance Pet
A bagless upright with a 30 ft cord, a manual carpet-height dial and a brushroll shutoff pedal. Its hose tools include a pet turbo tool, while the HEPA-media filter must not be washed.
- Best matched use
- You want a manual carpet-height dial.
Checked facts
- Floor response: Manual height and brush controls
- Detached floor-head use: Fixed upright
- Floor-nozzle height: Manual height dial
- Brush-off floor mode: Brushroll shutoff pedal
Meaningful differences
What changes the fit
| What changes | Shark PowerDetect Powered Lift-Away | Hoover WindTunnel 3 Max Performance Pet | Why it matters |
|---|---|---|---|
| Floor response | Floor, dirt, edge and direction detection | Manual height and brush controls | Shark changes settings automatically. Hoover exposes direct mechanical choices. |
| Detached floor-head use | Powered Lift-Away | Fixed upright | Only AZ4002 supplies powered main-nozzle cleaning with its pod removed. |
| Floor-nozzle height | No manual height dial established here | Manual height dial | Hoover supplies explicit user-selected height adjustment. |
| Brush-off floor mode | No manual suction-only mode established here | Brushroll shutoff pedal | Hoover documents direct shutoff for the main floor brush. |
| Floor-brush upkeep | Self-cleaning main brush and DuoClean rollers | Conventional main brush with screw-fastened access | AZ4002 addresses main-brush hair management. Neither eliminates inspection and obstruction care. |
| Selected fabric tools | HairPro Pet Power Brush and Pet Multi-Tool | Pet turbo tool and pivoting dusting tool | Both packages cover above-floor work, with different exact accessories. |
| Dirt collection | Bagless dust cup | Bagless bottom-release cup | Neither avoids dust-cup disposal by using a replacement bag. |
What you give up
Every choice has a cost
If you choose Shark PowerDetect Powered Lift-Away
- DuoClean adds a second roller to inspect and maintain.
If you choose Hoover WindTunnel 3 Max Performance Pet
- Main-brush access uses screws and the HEPA-media filter must not be washed.
Recommendation switch
The decision flips if...
Automatic sensing and powered detached-floor operation are priorities
Choose Shark PowerDetect Powered Lift-Away. AZ4002 combines those documented features.
Manual height and brush shutoff are required
Choose Hoover WindTunnel 3 Max Performance Pet. UH72625 provides the explicit controls.
What matters in practice
How to make the call
Use the carpet's requirement to frame the controls
A household wanting automatic adjustment can prefer PowerDetect without claiming better pickup. A household following a specific carpet-height or brush-off instruction may need the Hoover's direct controls. Neither approach guarantees suitability for every carpet. The surface manufacturer's care directions remain the starting point for that decision.
The Hoover hose is a deliberate mode change
UH72625 uses a FLOOR or HOSE air-routing dial, which must be changed for attachment use and returned afterward. AZ4002's removable powered configuration serves a different purpose: maintaining main-head floor cleaning with the pod out of the way. Compare the actual sequence you need instead of treating every detachable or extendable part as the same feature.
Separate exact-model evidence from the newer sales page
The Hoover linked here is UH72625, whose current manufacturer sales page can lead to UH72625V. This comparison uses the exact ASIN's linked manual and confirmed package, without borrowing the newer suffix's specifications. The same discipline applies to AZ4002 versus direct-site upgrade bundles, whose extra tools are not assumed.
What this comparison cannot tell you
- No matched cleaning-speed or pickup test supports a performance winner. Unresolved Shark numeric specifications and newer Hoover V-model claims are excluded.
