Introduction to the Dirt Devil Multi-Surface and Sanitaire SC679K
In the realm of vacuum cleaners, the Dirt Devil Multi-Surface Extended Reach+ is priced at $84.99, while the Sanitaire SC679K Tradition is available for $149.99. The significant price difference of about 43% may lead consumers to consider their individual cleaning needs and preferences. While both vacuums serve distinct purposes, understanding their features will help you make a more informed choice.
Design and Build Quality
The Dirt Devil Multi-Surface boasts a lightweight design, making it easy to maneuver from room to room. It is specifically engineered for home use, which means it prioritizes convenience and versatility. In contrast, the Sanitaire SC679K is a robust commercial vacuum, built with durability in mind. Its polycarbonate hood is designed to withstand tough environments, making it suitable for heavy-duty cleaning tasks. Weighing only 12.2 pounds, the Sanitaire is also lightweight but emphasizes longevity with a motor life of over 500 hours.
Cleaning Performance
When it comes to cleaning performance, the Dirt Devil Multi-Surface excels with its PowerPass technology, which prevents dust and dirt from scattering on hard floors. This vacuum is designed for both carpets and hard floors, equipped with a 4-level height adjustment feature to adapt to various surfaces. On the other hand, the Sanitaire SC679K focuses on commercial-grade cleaning performance. With a large-capacity shake-out bag that holds up to 18 quarts of dirt and debris, it minimizes interruption during cleaning, making it ideal for larger spaces.
Versatility and Tools
The Dirt Devil Multi-Surface is highly versatile, featuring a Click Lock tool kit that includes a 15” extension wand, a 2-in-1 crevice/dusting brush, and an upholstery tool. This allows users to tackle everything from high ceilings to furniture with ease. In comparison, the Sanitaire SC679K incorporates unique maintenance features, including a tool-free brush roll and belt replacement system. While it may not come with as many tools as the Dirt Devil, its ease of maintenance is a significant advantage for commercial users.
User Experience and Convenience
User experience is a vital aspect of any vacuum cleaner. The Dirt Devil Multi-Surface includes an easy-empty dirt cup with a one-touch release feature, streamlining the cleanup process. In contrast, the Sanitaire SC679K is designed for quick maintenance with its tool-free operations for replacing key components. Both vacuums place a strong emphasis on convenience, but the Dirt Devil’s easy-empty feature might appeal more to home users who prefer hassle-free cleanup.
Portability and Storage
Portability is crucial for any vacuum cleaner, especially when moving between rooms or floors. The Dirt Devil Multi-Surface's lightweight design enhances its portability, making it easy to carry. The Sanitaire SC679K, while also lightweight, shines with its 30-foot power cord, reducing the need to frequently switch plugs during larger cleaning tasks. This feature allows for a potential cleaning area of up to 4,680 square feet, making it ideal for commercial spaces.
Price Comparison
The Dirt Devil Multi-Surface is priced at $84.99, whereas the Sanitaire SC679K is priced at $149.99. This $65 price difference makes the Dirt Devil about 43% cheaper than the Sanitaire, appealing to budget-conscious consumers or those who primarily need a vacuum for home use. The Sanitaire’s higher cost can be justified by its commercial-grade features and durability, making it a worthy investment for businesses or larger households.
Which should you buy?
Ultimately, the choice between the Dirt Devil Multi-Surface Extended Reach+ and the Sanitaire SC679K Tradition depends on your specific needs. If you’re looking for a lightweight, versatile vacuum for home use that excels in cleaning various surfaces, the Dirt Devil at $84.99 is a compelling choice. However, if you're in need of a robust, commercial-grade vacuum that offers durability and a large capacity for heavy-duty cleaning, the Sanitaire SC679K at $149.99 may be worth the investment. Each vacuum has its strengths, so consider your cleaning requirements to make the best decision.
