Dimension comparison
Overview of the Kenmore DU4080 and Shark LA702
The Kenmore DU4080 Featherlite is priced at $132.99, making it significantly more affordable than the Shark LA702, which retails at $349.95. This price difference of approximately 62% may attract budget-conscious consumers. Both vacuums are designed for effective cleaning, but they cater to different needs and preferences in households.
Design and Portability
The Kenmore DU4080 is designed to be lightweight, weighing under 12 lbs, which enhances its portability and ease of use. Its Lift-Up Technology allows users to transition seamlessly to a lightweight pod, making it ideal for cleaning stairs and hard-to-reach areas. Conversely, the Shark LA702 features a Lift-Away function, enabling users to detach the pod for cleaning above-floor surfaces. While both models prioritize mobility, the Kenmore’s lighter weight gives it an edge for those seeking a more maneuverable option.
Suction Power and Cleaning Technology
The Kenmore DU4080 features a robust 2-motor system that provides powerful suction for deep cleaning on various surfaces, including carpets and bare floors. In contrast, the Shark LA702 is equipped with DuoClean PowerFins, which employ a two-brushroll system to engage carpets and hard floors deeply, ensuring comprehensive dirt and hair pickup. While both vacuums excel in suction capabilities, the Shark’s specialized brushroll technology may offer superior performance for homes with pets.
Filtration System
Both vacuums are equipped with HEPA filtration systems that trap 99.97% of dust and allergens. The Kenmore DU4080’s completely sealed air path ensures that contaminants remain within the vacuum, promoting cleaner air in your home. Similarly, the Shark LA702 employs Anti-Allergen Complete Seal Technology, which also prevents allergens from escaping back into the environment. Given that both models offer comparable filtration, users will benefit from cleaner air regardless of their choice.
Cleaning Tools and Versatility
The Kenmore DU4080 comes with versatile cleaning tools, including an upholstery tool and a 3-in-1 combination tool for various cleaning tasks. This versatility makes it suitable for a comprehensive clean throughout the home. On the other hand, the Shark LA702 includes specialized cleaning tools such as a crevice tool, upholstery tool, and an anti-allergen dust brush, enhancing its ability to tackle pet hair and fine dust. While both vacuums provide useful attachments, the Shark’s additional specialized tools offer more targeted cleaning options.
Odor Control Features
The Shark LA702 stands out with its Odor Neutralizer Technology, which guards against bad odors inside the vacuum, promoting a fresher-smelling home. This feature can be particularly appealing for pet owners or those sensitive to musty smells. The Kenmore DU4080 does not mention any specific odor control technology, indicating that while it effectively cleans, it may not address odors as comprehensively as the Shark model.
Maneuverability and Usability
Both vacuums boast advanced swivel steering and LED headlights, allowing for easy navigation around furniture and visibility of hidden debris. The Kenmore DU4080’s lightweight design enhances its maneuverability, while the Shark LA702’s advanced swivel steering ensures easy handling in tight spaces. Although both vacuums excel in usability, the Kenmore’s weight may offer greater ease for users who need to lift and move the vacuum frequently.
Price Comparison
The Kenmore DU4080 is priced at $132.99, making it about 62% cheaper than the Shark LA702, which is priced at $349.95. This significant price difference may be a decisive factor for budget-conscious buyers, especially those who require a reliable vacuum without breaking the bank. However, potential buyers should consider whether the additional features of the Shark justify its higher price, particularly for homes with pets.
Which should you buy?
Choosing between the Kenmore DU4080 and the Shark LA702 ultimately depends on your specific cleaning needs and budget. If you prioritize affordability and lightweight design, the Kenmore DU4080 is a compelling option at $132.99. However, if you are looking for advanced features like DuoClean PowerFins and Odor Neutralizer Technology, the Shark LA702, despite its higher price of $349.95, may be worth the investment. Consider your household requirements, especially if you have pets, to make the best decision.
