Side by side
Shark PowerDetect AZ4002 vs Hoover UH72625: Shark handles the floor response automatically, and Hoover offers manual height and brush control
Quick verdict
The Shark AZ4002 is the pick if you want automatic response to floor, dirt, edges and direction, plus Powered Lift-Away. The Hoover UH72625 is the pick if choosing the nozzle height yourself and having an explicit brush shutoff matter more. Both collect dirt in a cup and include fabric tools, so what separates them is how the floor heads are controlled and set up.
Before you buy
Why, and what it costs you
Wanting automation and wanting direct overrides are different priorities
If you want the machine to react to detected dirt, edges and floor changes, the AZ4002 is the stronger candidate. The UH72625 is the clearer one when a nozzle height you pick yourself, or a floor brush that is explicitly stopped, is non-negotiable.
Where this comes from
Evidence for the exact models points to sensing features on the Shark and a height dial plus shutoff pedal on the Hoover. Nothing here claims that sensing provides every manual control or guarantees compatibility with a surface.

Hose-tool work is done on a fixed upright.

In practice
Differences you will notice
Wanting automation and wanting direct overrides are different priorities

How we worked this out
Evidence for the exact models points to sensing features on the Shark and a height dial plus shutoff pedal on the Hoover. Nothing here claims that sensing provides every manual control or guarantees compatibility with a surface.
Powered Lift-Away alters how you clean as well as how you carry
The AZ4002 can take its pod out of the way and keep the main floor head powered. The Hoover is a fixed upright and reaches tight spots with hose tools. That distinction counts when the job is cleaning floors beneath furniture.
How we worked this out
Powered Lift-Away is documented for the selected AZ4002, and the Hoover manual shows hose use on a fixed upright. No measurement of clearance, handling force or minimum furniture height is available.
Hair management cuts down one chore, and other work is still left
If wrapped hair keeps sending you to the underside of a conventional head, the AZ4002's self-cleaning main brush matters. The Hoover manual has you remove six bottom-plate screws to get at that area. That does not make the Shark maintenance-free.
How we worked this out
The exact guide linked for the Hoover lays out the six-screw sequence for reaching the brush. The AZ4002 documents self-cleaning at the main roller, and both are still bagless machines that need ordinary care.
Option A
Shark, AZ4002
PowerDetect Powered Lift-Away
Four sensing functions tune the floor cleaning, and Powered Lift-Away means the dual-roller floorhead still works once the pod is detached.
- Best for
- You would like suction and brush speed to adjust automatically.
Facts we checked
- How it responds to the floor: Detects floor, dirt, edge and direction
- Using the floor head detached: Powered Lift-Away
- Height of the floor nozzle: No manual height dial is established here
- Floor mode with the brush off: No manual suction-only mode is established here
Option B
Hoover, UH72625
WindTunnel 3 Max Performance Pet
This bagless upright has a 30 ft cord, a manual carpet-height dial and a pedal that shuts off the brushroll. The hose tools include a pet turbo tool, and the HEPA-media filter must never be washed.
- Best for
- A manual carpet-height dial is what you want.
Facts we checked
- How it responds to the floor: Manual height and brush controls
- Using the floor head detached: Fixed upright
- Height of the floor nozzle: A manual height dial
- Floor mode with the brush off: A brushroll shutoff pedal
Spec by spec
Where they really differ
| Spec | Shark PowerDetect Powered Lift-Away | Hoover WindTunnel 3 Max Performance Pet | In practice |
|---|---|---|---|
| Floor response | Floor, dirt, edge and direction detection | Manual height and brush controls | Settings change on their own with the Shark, whereas the Hoover gives you direct mechanical controls. |
| Detached floor-head use | Powered Lift-Away | Fixed upright | Only the AZ4002 cleans with a powered main nozzle once its pod is removed. |
| Floor-nozzle height | No manual height dial established here | Manual height dial | The Hoover provides height adjustment that you set yourself. |
| Brush-off floor mode | No manual suction-only mode established here | Brushroll shutoff pedal | A direct shutoff for the main floor brush is documented for the Hoover. |
| Floor-brush upkeep | Self-cleaning main brush and DuoClean rollers | Conventional main brush with screw-fastened access | The AZ4002 covers main-brush hair management, but neither model ends inspection and obstruction care. |
| Selected fabric tools | HairPro Pet Power Brush and Pet Multi-Tool | Pet turbo tool and pivoting dusting tool | Above-floor work is covered by both packages, though the accessories are not identical. |
| Dirt collection | Bagless dust cup | Bagless bottom-release cup | Neither one lets you skip emptying a dust cup by using a replacement bag. |
Trade-offs
What each pick costs you
With Shark PowerDetect Powered Lift-Away
- With DuoClean comes a second roller you must inspect and maintain.
With Hoover WindTunnel 3 Max Performance Pet
- Reaching the main brush takes screws, and the HEPA-media filter must not be washed.
Change of plan
When the answer changes
Automatic sensing and powered floor cleaning while detached are what matter to you
Go with Shark PowerDetect Powered Lift-Away. Those documented features come together in the AZ4002.
You need manual height control and a brush shutoff
Go with Hoover WindTunnel 3 Max Performance Pet. The UH72625 has those explicit controls.
Decision guide
How to decide
Pick the Shark AZ4002 for automatic response to floor, dirt, edges and direction along with Powered Lift-Away. Pick the Hoover UH72625 if you rank manual nozzle-height selection and an explicit brush shutoff higher. Dirt goes into a cup on both and both come with fabric tools, so the meaningful difference lies in how their floor heads are controlled and configured.
Let your carpet's requirement frame the controls
If you want automatic adjustment, you can prefer PowerDetect without claiming it picks up better. If you must follow a specific carpet-height or brush-off instruction, the direct controls on the Hoover may be what you need. Neither approach guarantees it suits every carpet. Start with the care directions from the surface manufacturer.
Using the Hoover hose means switching modes on purpose
The UH72625 has a FLOOR or HOSE air-routing dial that you change for attachment use and set back afterward. The removable powered configuration of the AZ4002 does something else, which is to keep main-head floor cleaning going with the pod out of the way. Compare the actual sequence you need and do not treat every detachable or extendable part as the same feature.
Keep exact-model evidence apart from the newer sales page
The Hoover linked on this page is the UH72625, and the manufacturer sales page for it can currently lead to UH72625V. This comparison relies on the manual linked to the exact ASIN and on the confirmed package, with no specifications borrowed from the newer suffix. The same rule applies to the AZ4002 and direct-site upgrade bundles, whose extra tools are not assumed.
What this page can’t tell you
- No performance winner is declared, because no matched cleaning-speed or pickup test exists. Unresolved Shark numeric specifications and newer Hoover V-model claims are left out.
