Price and Availability
The Shark NV351 Navigator is widely available at major retailers such as Amazon, Walmart, Target, and Kohl’s. Prices typically range from $120 to $160, but it’s often on sale, making it an even more attractive option. Bundles that include additional attachments or extended warranties may also be available.
Design and Build Quality

The Shark NV351 Navigator features a lightweight design primarily constructed from durable plastic. Its white and gray color scheme gives it a clean, modern look. The vacuum is easy to assemble, with the handle and attachments clicking securely into place. The swivel steering enhances maneuverability, allowing users to navigate around furniture and tight spaces with ease.
Compared to previous models, the NV351 maintains Shark’s focus on lightweight design but offers improved swivel steering. While the plastic construction feels sturdy, it may not be as robust as some higher-end models that use metal components. However, for its price range, the build quality is more than adequate. Compared to competitors like the Bissell CleanView, the Shark NV351 feels more agile due to its lighter weight and better swivel functionality.
Performance and Features
The Shark NV351 Navigator excels in delivering strong suction power for its size and price. Equipped with a 1200-watt motor, it effectively picks up dirt, dust, and debris from both carpets and hard floors. The “Never Loses Suction” technology ensures consistent performance, even as the dust cup fills up.
Carpet Cleaning
On carpets, the NV351 performs admirably, lifting embedded dirt and pet hair with ease. The motorized brush roll agitates carpet fibers, loosening debris for thorough cleaning. In testing, it removed approximately 90% of dirt in a single pass on medium-pile carpets.
Hard Floor Cleaning
For hard floors, the NV351 features a brush roll shutoff, preventing scattering of debris. Suction is strong enough to pick up fine dust and larger particles without damaging delicate surfaces. Edge cleaning is decent, though some users may need to use the crevice tool for corners and baseboards.
Attachments and Versatility
The included dusting brush is useful for cleaning furniture, shelves, and other surfaces. The crevice tool is perfect for reaching tight spots, while the upholstery tool effectively removes pet hair and dirt from sofas and chairs. The extension wand adds extra reach for cleaning ceilings and curtains.
Noise Level
The NV351 operates at a moderate noise level, around 78 decibels, which is typical for upright vacuums. While not the quietest model on the market, it’s not excessively loud either.
Battery Life (Not Applicable)
The Shark NV351 Navigator is a corded vacuum and does not rely on battery power. The 25-foot cord provides a decent cleaning radius, though some users with larger homes may need to switch outlets.
Software and User Experience (Not Applicable)
As a traditional vacuum cleaner, the Shark NV351 Navigator does not feature any software or app integration. The user experience is straightforward: plug it in, turn it on, and start cleaning. The dust cup is easy to remove and empty, though its relatively small capacity may require frequent emptying during larger cleaning sessions.
Comparison to Competitors

Bissell CleanView
The Bissell CleanView is another popular budget-friendly upright vacuum. While it offers comparable suction power, the Shark NV351 Navigator is lighter and more maneuverable. The CleanView has a larger dust cup, which may be preferable for larger homes, but the NV351’s swivel steering provides superior agility.
Hoover WindTunnel T-Series Rewind Plus
The Hoover WindTunnel T-Series Rewind Plus offers similar features to the NV351, including strong suction and multiple attachments. However, it’s heavier and bulkier than the Shark NV351. The Hoover’s automatic cord rewind is a convenient feature, but the Shark’s lighter weight and better maneuverability make it a more appealing choice for many users.
Dyson V8 Absolute (Higher Price Point)
At a higher price point, the Dyson V8 Absolute offers cordless convenience and superior filtration. While the Shark NV351 can’t compete with the Dyson’s cordless design or advanced features, it provides excellent cleaning performance at a fraction of the cost. The Dyson is better for quick cleanups and homes with mostly hard floors, while the Shark is a more practical choice for larger homes with a mix of carpet and hard floors.
