Shark NV751 vs AZ1002: Both own most of Shark’s punches and are favored by many. But if you have to choose one of these models, I would suggest the second one.
Shark NV751 and Shark AZ1002 share many bells and whistles. But one thing that the AZ1002 has over the other is that it has a DuoClean nozzle that allows it to work well on both carpets and hard floors. Additionally, it has a self-cleaning brush roll, which makes it ideal for pet owners.

Shark NV751 vs AZ1002: Differences
The Shark AZ1002 wins 2-1 against the NV751 since the first one works better on hard floors and carpets, thanks to the DuoClean feature. Plus, its self-cleaning brush roll ensures a good amount of sucked pet hair will be sent into its dust cup.
Cleaning Performance
Winner: Shark AZ1002
Carpet
I put chili flakes, split green peas, and flax seeds on my low-pile carpet for this test. My test showed that almost everything was captured, and there was almost no difference between the Shark NV751 vs AZ1002 in this test. They were pretty close and weren’t perfect.
I also tested these two vacuums with larger debris like full-size fruit loops, and the DuoClean nozzle on the AZ1002 had some advantages here.
Hard Floor
I also used small-to-medium-sized debris, such as ground cheerios and flax seeds, and some larger debris, like fruit loops, in this test. The AZ1002 shone here, and it significantly outperformed its competitor. Its soft brush roll helped quite a bit on a smooth surface.
Hair
Both Shark NV751 vs AZ1002 did an excellent job removing the pet hair, but I could see the difference in the amount stuck on their brush rolls. The AZ1002 had much less hair remaining on its brush roll than the NV751, thanks to Zero-M Technology, which tends to continue removing hair as you clean.
Weight
Winner: Shark NV751
The weight of the Shark NV751 vs AZ1002 is 15.4 lbs and 16 lbs, respectively. So the first one wins this round since it’s a bit lighter.
For me, they’re neither lightweight nor heavy, and carrying them around isn’t a daunting task. But many users have complained that they experience back pain after using these machines for a long time. Just know your limit!
Utilities
Winner: Shark AZ1002
Regarding bells and whistles, the Shark NV751 vs AZ1002 is generally quite similar. But what the AZ1002 has in its favor is its DuoClean nozzle with a self-cleaning brush roll.
The DuoClean head of the AZ1002 has two rollers: a soft roller at the front and the main brush roll in the back. As a result, this machine works flawlessly on both hard floors and carpets.
On the other hand, the back brush roll has fins and bristles that help it remain reasonably hair free, which is why it’s called “self-cleaning.” So if you’re a pet owner with dogs that shed like crazy, the AZ1002 is your best bet. It didn’t work magically as Shark claimed, but it worked.
Shark NV751 vs AZ1002: Similarities
Alternate Configuration
Both the Shark NV751 vs AZ1002 are known as 3-in-1 vacuums, but I discovered that they could even be used in four configurations, including the upright configuration.
They have a powered lift-away feature, which means you can detach their canisters from their cleaner heads and use them as semi-handheld vacuum cleaners. This configuration is ideal for cleaning hard-to-reach areas such as bookshelves or stairs.
After lifting the canister, their floorheads still work, so you can use these machines as stick vacuums to clean under furniture.
Finally, both the Shark NV751 vs AZ1002 can be used as canister vacuums by placing their pods on something called the “caddy.” This part can also be used as extra storage for attachments. I call it to kill two birds with one stone!
Vacuum Controls
Their handles have a power On/Off button and a slider with three surface settings: “Thick Carpet/Area Rug,” “Carpet/Low Pile,” and “Hard Floor.” The floor settings are a bit harder to see on the AZ1002 with the vacuum power off, but not a big deal. All the controls are at your fingertips, which is nice for those with back pain.
Led Lights
Both the Shark NV751 vs AZ1002 have some LED bulbs in front of their nozzles, allowing you to detect any dust and dirt in poorly lit areas easily. Better yet, they also have a light on the handle, so you can keep the area you’re cleaning illuminated using the wand or the included accessory.
Filter
Both the Shark NV751 vs AZ1002 come with HEPA filters, which can capture up to 99.97% of dust, dirt, and allergens. But they won’t work correctly without the anti-allergen complete seal, which ensures no dirt and allergens can escape into the air while you vacuum.
Cord Length
The Shark NV751 vs AZ1002 shares a 30-foot power cord, and I think it is long enough to clean large areas without spending extra time looking for outlets. Anything shorter can be annoying! These cords aren’t retractable, and you’ll need to wrap them manually.
