The Shark PowerDetect AZ4002 is a feature-rich upright for carpets, hard floors and pet hair. Its Floor Detect, DuoClean Detect and PowerDetect systems automatically adjust cleaning behavior, while Powered Lift-Away helps with stairs, furniture and other above-floor surfaces.

The main trade-off is size. At 17.6 lb and 80 dB, it may feel like more vacuum than you need if your priority is a lighter body or quieter cleaning.

See cordless upright vacuum options if avoiding a power cord is also important.

Shark PowerDetect upright vacuum review: what stands out

The AZ4002 stands out because it uses sensors to change suction and brushroll speed as floor conditions change. That reduces the need to stop and select a different cleaning mode when moving between carpet and hard flooring.

The vacuum has a 2.02-quart capacity, an eggplant matte finish and an 11.8 A rating. Its dimensions are 12.01 in long, 15.12 in wide and 46.18 in high, so measure storage space and doorways before choosing it.

Shark identifies the AZ4002 as an upright with a HEPA filter, Powered Lift-Away and DuoClean technology. The product includes a Pet Multi-Tool, Duster Crevice Tool, HairPro Self-Cleaning Pet Power Brush, Odor Neutralizer Technology Cartridge and Owner's Guide.

Who should choose the Shark PowerDetect upright vacuum?

Choose the AZ4002 if you want automatic adjustment across floor types and dedicated tools for pet hair. It is especially suited to homes where carpets, hard floors, stairs and upholstered furniture all need regular cleaning.

The AZ4002 may be more than you need if you mostly clean one floor type. In that case, a lighter upright with manual controls may offer a simpler daily routine.

How does PowerDetect cleaning work?

PowerDetect responds to embedded dirt, edges, floor type and cleaning direction. The system is designed to keep suction and brushroll performance adjusted as you move forward, reverse or along room edges.

DuoClean Detect uses two brushrolls and four Intelli-Sense sensors. These sensors detect hidden dirt, debris, pet hair and floor type, then adjust suction and brushroll speed for carpets and hard floors.

Floor Detect focuses on the change between carpet and hard flooring. You don't need to stop and change the setting each time you cross a threshold.

These are automatic features, not a promise that every pass removes every particle. Room layout, debris type and how slowly you move the vacuum still affect cleaning.

Shark's official product information for the PowerDetect AZ4002 explains the system and included tools.

Is it a good pet vacuum?

The AZ4002 is a strong fit for pet homes because it combines a self-cleaning brushroll with a dedicated HairPro Self-Cleaning Pet Power Brush. The handheld tool is intended for embedded pet hair on stairs, upholstery and furniture.

The Pet Multi-Tool gives you another option for pet hair and debris. The Duster Crevice Tool targets dust and narrow spaces such as corners, edges and gaps around furniture.

The vacuum's Odor Neutralizer Technology helps guard against bad odors inside the vacuum. It includes an Odor Neutralizer Technology Cartridge, so follow the Owner's Guide for cartridge care and replacement instructions.

Pet hair can collect in more places than the main floor. Use the powered handheld setup for stairs and furniture, then return the pod to the upright when you need floor cleaning.

How does the HEPA filtration compare?

The AZ4002 uses a HEPA filter and Anti-Allergen Complete Seal. Shark says this combination traps 99.99% of dust and allergens inside the vacuum based on ASTM F1977 particles 0.3 microns or larger.

That claim refers to non-living matter. It does not mean the vacuum removes every source of allergy symptoms from a home.

The sealed design matters during emptying and regular care because captured material is intended to stay inside the vacuum. Follow the Owner's Guide for filter cleaning and replacement steps.

If filtration is your main concern, compare the AZ4002 with the Shark Stratos upright vacuum reviews before deciding.

What does Powered Lift-Away do?

Powered Lift-Away lets you detach the pod while the powered brushroll continues spinning. This gives you a way to clean stairs, upholstery, furniture, windowsills and other hard-to-reach areas without losing powered brushroll cleaning.

The detached pod can also support cleaning under furniture. The advantage is more reach and flexibility than a standard upright mode, but you still need to manage the hose and selected tool.

Use the HairPro Self-Cleaning Pet Power Brush for embedded pet hair on stairs and furniture. The Duster Crevice Tool is better suited to narrow spaces, edges and dusting tasks.

Before buying, check the storage area for the full upright and its tools. A detachable pod helps during cleaning, but it doesn't remove the need to store the main vacuum.

AZ4002 compared with two Shark alternatives

The AZ4002 is the most automation-focused option here. The Navigator NV356E is lighter, while the NV752 adds LED headlights and a 12 in cleaning path.

The Navigator is 3.9 lb lighter than the AZ4002 and has a 5 ft hose. It uses brushroll shutoff for hard floors instead of the AZ4002's automatic floor sensing.

The NV752 has a 12 in cleaning path, LED headlights and a 0.88-quart capacity. Its Powered Lift-Away design is similar in purpose, but automatic dirt and floor adjustments are not specified.

Our best Shark Navigator vacuum guide is useful if the lighter NV356E sounds closer to your needs.

Shark PowerDetect upright vacuum review: daily-use trade-offs

The AZ4002's strongest daily-use benefit is reduced mode switching. You can move from carpet to hard floor while the vacuum responds to the change in surface.

Its largest practical drawback is the 17.6 lb weight. That is manageable for floor cleaning, but carrying an upright up stairs or storing it on a different level may take more effort than a lighter model.

The 80 dB noise level is another factor. If you clean while other people are sleeping, working or watching television, compare the stated noise level with your household routine.

The 2.02-quart capacity is useful for longer cleaning sessions. A larger cup can mean fewer interruptions, but you should still empty it before debris reaches the level recommended in the Owner's Guide.

How should you choose between these Shark uprights?

Choose the AZ4002 for automatic adjustment, larger capacity and advanced pet-hair tools. It is the better match when your home has mixed flooring and you want the vacuum to respond to dirt and surface changes.

Choose the Navigator NV356E if lower weight, brushroll shutoff and a washable HEPA and foam filter setup matter more than automatic sensing.

Choose the NV752 if LED headlights, a 12 in cleaning path and powered above-floor cleaning are your priorities. You can compare Hoover upright vacuum options if you are still weighing upright styles.

Its controls switch between Hard Floor and Carpet modes, so it offers direct manual control.

Verdict: is the Shark PowerDetect AZ4002 worth considering?

The Shark PowerDetect AZ4002 is the best fit for mixed-floor homes with pets when automatic cleaning adjustments are worth the heavier body. Its 2.02-quart capacity, HEPA filtration, Powered Lift-Away and included HairPro tool cover many common floor and above-floor tasks.

Pick the Navigator NV356E when you want a lighter 13.7 lb upright with brushroll shutoff. Pick the NV752 when LED headlights and a 12 in cleaning path matter more than automatic dirt detection.
