Design and Build Quality
The Dyson Big Ball stands out with its spherical design, allowing it to self-right when toppled over. This feature is not just a gimmick; it genuinely improves the user experience by preventing interruptions during cleaning. The materials used in the Dyson Big Ball feel premium and durable, reflecting its higher price point. The overall construction exudes quality, with well-fitted parts and a solid feel. However, its weight can be a drawback for some users, especially when carrying it up stairs.
In contrast, the Shark Navigator adopts a more traditional upright vacuum design but introduces the Lift-Away feature, allowing the canister to detach from the main unit for portable cleaning. This design offers versatility, making it easier to clean stairs, upholstery, and hard-to-reach areas. While the build quality of the Shark Navigator is generally good, it doesn’t quite match the premium feel of the Dyson Big Ball. The plastic components feel less robust, although they are still durable enough for regular use. The Shark Navigator’s weight varies depending on the specific model, but it is generally lighter than the Dyson Big Ball, making it easier to maneuver for some users.
Performance and Features
Suction Power
Both the Dyson Big Ball and Shark Navigator are renowned for their strong suction power. The Dyson Big Ball utilizes its Radial Root Cyclone technology to generate powerful centrifugal forces, effectively capturing dirt and debris from carpets and hard floors. Dyson claims that its technology maintains consistent suction power, even as the dust bin fills up.
The Shark Navigator also boasts impressive suction, often rivaling the Dyson in head-to-head tests. The Navigator’s suction is particularly effective on carpets, where it can lift embedded dirt and pet hair with ease. However, some users have reported that the Shark Navigator’s suction can be too strong on delicate rugs or hard floors, requiring adjustment of the suction control settings (if available on the specific model).
Filtration
Filtration is a critical aspect of vacuum cleaner performance, especially for allergy sufferers. The Dyson Big Ball features whole-machine HEPA filtration, meaning that the entire vacuum is sealed to prevent allergens and dust from escaping. This is a significant advantage for those with sensitivities, as it ensures that the air expelled by the vacuum is clean and allergen-free.
While many Shark Navigator models include HEPA filtration, not all offer whole-machine filtration. This means that some models may release a small amount of dust and allergens back into the air. If filtration is a top priority, it’s essential to check the specifications of the specific Shark Navigator model you are considering.
Maneuverability
The Dyson Big Ball’s unique design contributes to its excellent maneuverability. The ball allows the vacuum to turn and pivot smoothly, making it easy to navigate around furniture and obstacles. However, its weight can make it challenging to push across thick carpets for extended periods.
The Shark Navigator also offers good maneuverability, thanks to its swivel steering. The Lift-Away feature further enhances its versatility, allowing you to detach the canister and carry it separately while cleaning stairs or other elevated surfaces. However, some users find the Shark Navigator to be less agile than the Dyson Big Ball, especially in tight spaces.
Attachments and Accessories
The Dyson Big Ball typically includes a combination tool and a stair tool, which are useful for cleaning upholstery, crevices, and stairs. However, some users may find the attachment selection to be limited compared to the Shark Navigator.
The Shark Navigator often comes with a wider range of attachments, including a crevice tool, dusting brush, and pet power brush. The pet power brush is particularly effective for removing pet hair from carpets and upholstery. The availability of these attachments varies depending on the specific Navigator model.
Battery Life
Since both the Dyson Big Ball and Shark Navigator are corded vacuums, battery life is not a relevant factor. The cord length is an important consideration, as it determines the vacuum’s reach. The Dyson Big Ball typically has a longer cord length than the Shark Navigator, providing greater freedom of movement.
Software and User Experience
As traditional upright vacuums, neither the Dyson Big Ball nor the Shark Navigator relies heavily on software. The user experience is primarily determined by the design, features, and ease of use.
The Dyson Big Ball is known for its simple and intuitive operation. The self-righting feature and consistent suction power contribute to a hassle-free cleaning experience. However, some users may find the dust bin emptying process to be less convenient compared to the Shark Navigator.
The Shark Navigator’s Lift-Away feature enhances its versatility and ease of use, allowing you to quickly switch between upright and portable cleaning modes. The dust bin is typically easy to empty, and the controls are straightforward.
