In the comparison of Shark NV352 vs UV850, both of them have comparable suction and cleaning performance, but the Shark UV850 is greater in the utility aspect.
The Shark UV850 has DuoClean brush rollers with a self-cleaning feature, which helps cleaning pet hair and dirt be an easy task. The brush roll will not be fully wrapped with hair. It also has a longer cord of 30 ft., more accessories, and very bright LED headlights. It also works well on bare and hardwood floors, though on carpets, its performance is just okay.
On the other hand, the Shark NV352 has the traditional bristle brush roll, which easily gets clogged by hair wrapping. It does not have LED headlights, and the cord is quite short. However, its cleaning performance on carpets is greater than that of its rival. Yet, cleaning on bare floors is not that excellent. Generally, NV352 still meets basic cleaning requirements with its incredible suction and is a budgeted pick for those who have most of their house carpeted.

Shark NV352 vs UV850: Differences
The Shark UV850 wins 1-0 against the Shark NV352 in terms of utility. In the cleaning performance and design convenience categories, they are comparable as each has pros that outweigh the other.
Cleaning performance
Tie!
Suction strength and control
Overall, both of these vacuums have excellent suction for pulling all types of dust on carpets and floors. The sealed suction at the hose of Shark NV352 vs UV850 is 89 inches vs 80 inches, respectively. As you can see, the suction of the Shark NV352 is somehow stronger than that of the Shark UV850.
Their strong suction sometimes causes difficulty in vacuuming the rugs and carpets as they are hard to push and pull on such surfaces. They often grab my carpets up when I try to pull them back.
Fortunately, the suction of Shark NV352 and UV850 can be adjusted to make it easier to maneuver on thin and thick carpets. The suction adjustment can be performed on Shark NV352 by twisting the Suction Release collar and on UV850 through the Suction Control slider.
Brushroll system
Differences in the brush roll system between the Shark NV352 vs UV850 come from the design and functionality. The Shark UV850 has two rollers, one with a soft brush and one with plastic fins. Meanwhile, the Shark NV352 has a single roller with bristles. Besides, the Shark NV352 offers the brush roll shutoff functionality, while the Shark UV850 doesn’t.
- DuoClean and self-cleaning brush roll
The distinguishing designs definitely result in differences in cleaning function. In the case of Shark UV850, the brush roll is called DuoClean PowerFins, which is claimed to have the ability to dig deeply into carpets to effectively pull out the embedded dirt while engaging the floor directly to create a better seal for better pick-up performance.
Moreover, the brush roll of Shark UV850 comes with a self-cleaning feature to reduce the hair tangled on the brush roll. Well, I can say that this self-cleaning brush toll did better than the traditional bristle brush roller of the Shark NV352. The amount of pet hair stuck on the brush roll after cleaning my whole apartment is insignificant, helping me out of the daunting task of clipping hair on the brush roll like when using the Shark NV352.
In fact, the self-cleaning brush roll doesn’t mean you’re free of maintaining the brush roll; it means making cleaning rollers easier and less strenuous. I still clean the brush roll weekly or after every extreme cleaning of my apartment to ensure the rollers and the vacuum function properly. The front roller of the Shark UV850 is very easy to detach and clean. The amount of hair tangled on its rollers is insignificant, so I am very pleased with it.
- Brushroll shutoff functionality
The Shark UV352 can offer you this, while with the Shark UV850, it is impossible to disengage the brush rollers when the vacuuming is on and tilted back. More specifically, the brush roll of Shark NV352 can be turned off in the bare-floor setting. Meanwhile, in that setting, the brush rollers of Shark UV850 are still spinning.
When vacuuming bare and hard floors, turning off the brush roll is very useful for avoiding debris scattering and damaging delicate floors. So, the Shark NV352 can work on wood or vinyl plank flooring. The UV850, though it cannot stop the brush roll motion, can also work great on wood floors, owing to its brush roll design, reducing the scratching of bristles and debris on such surfaces.
Floor-type compatibility
- Carpeted surfaces:
The NV352 outperforms the UV850 in terms of carpet cleaning. Though both of them have impressive suction, the power-fin brush roll of the Shark UV850 seems not to give enough agitation or dig into the carpet to loosen the dirt and pet hair as the bristle brush roll of the Shark NV352 does.
The Shark NV352 did relatively better for the deep cleaning carpet test, especially for picking up the fine and coarse sand particles. It picks up almost all the debris embedded in the carpet in just one time of pulling back and forth. Meanwhile, the amount of sand left on the carpet after vacuuming with the Shark UV850 is a bit more with the same pass.
Besides, Shark UV850 and NV352 performances on area rugs are not great because they pull the rug off the floor and are hard to push over the area. Additionally, these two vacuums do not have adjustable roller heights, so working on high-pile, thick, and dense carpets could be cumbersome.
- Bare floors / Hard floors:
On bare floors or hardwood floors, the Shark UV850 works relatively better than its rival, the Shark NV352. Particularly, it sucks up all the hair from nooks and crannies. The dual rollers do a good job of picking up the dirt, pet and human hairs, and debris without scattering them away. Though its brush roll does not completely shut off in the bare-floor setting, the soft roller at the front helps catch the debris to increase the pick-up performance.
Meanwhile, the Shark NV352 is inferior in bare-floor cleaning. Generally, it can also pick up little particles and pet hair on the wood floors. However, it still has the large stuff like fruit loops move rounds and has to use the hose to collect all of the particles. Moreover, when vacuuming long hair in the bare floor setting, the hair just gets stuck on the brush roller rather than sucked into the dirt bin unless the brush roll is turned on.
Design & Convenience
Tie!
Between the Shark NV352 vs UV850, the former is slightly lighter, while the latter has a longer cord. The weight between these two models is just about 1 pound, but overall, they are relatively lightweight vacuums compared to some products of other brands.
The cord length of the NV352 is 25 ft., which is decent for an apartment but insufficient for vacuuming a big house. However, with a 30 ft. cord, the UV850 can provide a greater reach for you, avoiding disturbing your cleaning session to unplug and re-plug in the cord.
Besides, both of them have nice swivel heads and lift-away canisters, so maneuvering them is quite easy and so they do not tax my back when carrying it to clean the stairs.
However, they have some minor drawbacks in their design. One is the awkward position of the control button. Like other Shark upright vacuums, the NV352 and UV850 have the floor-to-carpet control button on the canister, which may be inconvenient for some users. It is because you have to constantly reach down to change the setting, especially when your apartment is mixed between carpets and bare floors.
Another drawback is that their canister position is not ideal as it limits the reach of the vacuum under low-sitting furniture, though their cleaning heads are quite thin and able to go under such pieces. However, if they have the powered lift-away functionality just like the Shark Vertex, the under-reach range can be extended as you can lift off the canister from the base and the wand, turning the vacuum into a stick vacuum.
Utility
Winner: Shark UV850
LED headlights
The bright LED headlights make the Shark UV850 shine in terms of cleaning utility. It helps me to obviously see the hidden dust and hair and where I have missed vacuuming, especially in darker areas like under furniture.
Attachments
Generally, the Shark UV850 has a greater attachment set than the NV352, as it has more accessories. The Hair Removal Multi-Tool of the UV850 is actually a combination of the Upholstery Tool and the Dusting Brush. However, for me, this combination is a bit weird and hard to use, especially when using the dusting brush. It may be because of the angle of this attachment.
On the other hand, the Shark NV352 has only two accessories, including Upholstery tool and Crevice tool. It lacks the dusting brush, which, for me, is an essential attachment for cleaning dust on blinds and wardrobe tops.
Shark NV352 vs UV850: Similarities
Their similarities are in filtration, dirt bin capacity, swivel head, and lift-away canister. Shark NV352 and UV850 feature a ~1.2-quart dirt bin and Allergen-Seal HEPA filtration. Their capacity is sufficient for use in apartments, but it needs emptying several times during one cleaning when used for big houses. The fully-sealed HEPA filtration is helpful for people with allergies like me, as when vacuuming with them, I barely sneeze!
Additionally, they have nice swivel heads for controlling and turning around corners and furniture. Their lift-away canisters are easy to detach, carry, and put back. Such portable canisters help me a lot when vacuuming stairs. I don’t have to bring the vacuum all the way, and this significantly reduces the amount of pressure taxing on my lower back.
