The Design

Basically, the Shark NV831 vs NV801 are different from each other when it comes to appearance. They come with different shades and in my opinion, the NV831 looks more fierce and gives strong vibe. While the NV801 is available in red, the other is covered with black (mostly) and red. There is a difference in terms of height. Shark NV801 is much taller than the NV831, 46.1 and 34.5 inches. The taller it is, the more convenient you feel because you don’t have to bend much and it is good for your back too. In addition, both include LED lights on nozzle lights to illuminate areas which desperately need your cleaning attention. Lastly, they are equipped with powered Lift-away technology, a very famous feature of Shark. With this function, you can easily carry the machine around and even up and down stairs.

The Portability

Shark NV801 is lighter than the NV831, 15 and 17.1 pounds. In addition, Shark NV831 and NV801 are equipped with swivel steering feature which makes them highly maneuverable. Besides, their nozzle heads are equally a bit narrow and low-profile, which allows users to get to tight places, such as under low-profile furniture. To make thing easier, both Shark NV831 and NV801 have wheels to lessen the weight, which makes it flexible for people to push the machines around. It is easier for you to move in on both hard surfaces and carpets. Especially, we have to take their lift-away mode into account. This functions comes in handy for their enhanced portability. The machines allow you to lift the canister away and deep clean hard-to-reach areas while still delivering power to keep the brushroll spinning.

The Cleaning Performance

Shark NV831 and NV801 both belong to the NV800s series, which is pretty new and advanced. Through 2 sections above, you can see that they are a bit different in many aspects. The NV831 has some features which the NV801 doesn’t and vice versa. Yet, let’s see them in detail first before jumping into any conclusion.

The Features:

  • Both Shark NV831 vs NV801 are armed with Shark’s well-known Never Loses Suction technology. It explained that the technology ensures the machine can continually provide strong suction over an extended length of time. Therefore, you don’t have to worry about abrupt loss of air flow like many other products.
  • Both feature LED headlights on the floor nozzle, which allows you to spot hidden dust in dark areas and makes sure so dirt left behind.
  • Another similarity between these two is that they both come with HEPA filtration system and the Anti-Allergen Complete Seal technology. This combination is great for removing fine dust and allergens in your house, up to 99.97% statistically. The air is return fresh and safe for your health. You must consider these two if any family member is suffering from allergy symptoms or simply you want to avoid the bad quality air around the house.
  • Like I mentioned above, both Shark NV831 vs NV801 feature 3-in-1 lift-away function. It means the vacuum can function as upright, lift-away or canister cleaner. In the upright mode, the two brushrolls on the nozzle head will spin and the soft roller sucks up the large debris, while the soft one picks up find dust. By pressing Lift-away release button, you can detach the canister section from the vacuum in order to clean stairs, upholstery, drapes and so on. With canister mode, the cleaner can clean floors as well as elevated surfaces.
  • Also, fingertip controls allow for easy powering on/off and quick transition between hard floor and carpet mode.
  • Both have 30ft power cords, which are more than enough for you to cover a large area with a single plug.

The Difference:

  • Shark NV831 vs NV801 are both equipped with DuoClean technology that feature two different brushrolls, soft and stiff ones. These brushes will spin in harmony to remove fine and tough dirt at the same time.
