If you’re not new to using vacuum cleaners, the Shark name is probably familiar to you. It’s one of those brands that is known for creating these products that are usually of very high quality. In this article, the focus is going to be on two models, respectively NV400 and NV501.

They will be compared so you can decide which one has the better features in your book. Thus, you will end up with a product that is actually beneficial to your household.


In terms of design, it may be confusing to try and differentiate them from each other, because both the Shark NV400 vs NV501 have the same look. The colors they come in are the same, respectively a combination of red and white.

Another similar thing they have is the cord length, which is of 30’, being great in moments when you want to save some time. You won’t have to plug it in/out often. In addition, both of them work best when it comes to cleaning bare floors, hardwood floors, carpets and getting rid of pet hair.

Weight is another aspect in which they’re similar. The difference is very small, NV400 having 15.6 pounds, while NV501 has 15.8 pounds.

One helpful feature incorporated in these models is the swivel steering feature, which makes it easier to handle hard-to-reach areas, as well as various obstacles. Consequently, reaching spaces such as under the furniture, bed, cabinet, and table will be a piece of cake.

A difference between the two models when it comes to the design is the fact that NV501 has the Lift-away function, while its counterpart doesn’t. This function allows you to clean smaller spaces and stairs much easier.

Between the Shark NV400 vs NV501, the Shark NV501 is the more expensive option compared to NV400, but it’s still not that much of a difference to make it unaffordable.


Portability is important because you’d usually want something that is lightweight enough so that you are able to move it from one room to the other. They are both pretty lightweight, with the NV400 being a little lighter than its competitor. However, the NV501 has the lift-away function that is helpful when cleaning curtains, ceilings, and stairs.

Cleaning Performance

In a vacuum cleaner, the most important feature you are looking for is the cleaning performance. As such, you’ll be happy to know that both models presented in this article are giving very satisfying results. Whereas they may not be the most high-end machines, they are surely providing benefits that are beyond expectations. Therefore, they could be very helpful in your household.


HEPA Filters and Anti-Allergen Complete Seal Technology

Are you sick of vacuum cleaners that just send the dust particles back in the air after vacuuming? With these items, this won’t bother you anymore. Shark decided to make the NV501 and NV400 in such a way that the air is filtered, thus allowing you to breathe air free of dust and allergens.

They have HEPA filters, as well as anti-allergen complete seal technology. As a result, the filters can trap nearly all the allergens and dust inside the vacuum cleaner.


When you purchase any type of product, it’s a fact that you want it to last for a long time. Thankfully for you, the Shark NV400 and NV501 offer durability, as well as easy maintenance.

Moreover, even if they break, you should know that the vacuums have 5 years of warranty.


Sometimes, you have to clean in spaces that are not bound to receive any light, and it’s hard to see whether you’re successfully getting rid of the dirt there. These vacuums have headlights that help add light to these areas while you’re cleaning them, so the end result is visible.

Never-Loses Suction

Over time, some items wear out and tend to lose their power, thus not providing you with the same benefits they used to at the beginning. This could happen to vacuums as well, and they lose their suction power; thus, they will not be as effective as they were when you purchased them.

With these Shark models, you are free of worries, because they both have Never-Loses Suction technology. Therefore, not only that your cleaning session won’t be interrupted, but you will also own a machine that has the same suction power even after years of use.

Rotator Technology

The swivel steering technology moves more efficiently in these products due to the rotator technology, which allows them to easily pass all the corners in the room.

Pet Power Brushes

Owning a pet can give you a lot more work to do. They leave hair on every surface, and you are left having to struggle to get rid of it. Because of that, these Shark vacuums come with a pet power brush, so you can remove the hair from the floors, as well as the furniture.
