Price Comparison
The Sanitaire SC679K Tradition Upright Commercial Bagged Vacuum is priced at $149.99, making it significantly cheaper than the Shark Upright Vacuum, which retails for $299.99. This means that the Sanitaire is about 50% less expensive than the Shark. The price difference could be a considerable factor for budget-conscious consumers or businesses looking for cost-effective cleaning solutions. While the Shark offers advanced features and technology, the lower price point of the Sanitaire makes it an appealing option for those who need reliable, no-frills commercial cleaning.
Performance and Power
When it comes to performance, the Shark Upright Vacuum excels with its ultra-powerful suction and advanced cleaning technologies. It features a DuoClean PowerFins system, which ensures optimal dirt and hair pickup across various surfaces. In contrast, the Sanitaire SC679K provides over 500 hours of commercial-grade cleaning performance, which is impressive for its price point. However, its motor power is listed at 800 watts, which may not match the suction capabilities of the Shark’s advanced system. For those who prioritize powerful suction and advanced features, the Shark may be the better choice.
Cleaning Technology
The Shark Upright Vacuum incorporates several advanced cleaning technologies, including a self-cleaning brushroll that prevents hair wrap, making it ideal for pet owners. Additionally, its odor neutralizer technology helps to keep your home smelling fresh. On the other hand, the Sanitaire SC679K offers a more traditional cleaning approach with a large-capacity shake-out bag that can hold up to 18 quarts of dirt and debris. While the Sanitaire is designed for straightforward commercial use, those seeking cutting-edge cleaning features might find the Shark more appealing.
Maintenance and Usability
In terms of maintenance, the Sanitaire SC679K is designed for ease of use, featuring a tool-free brushroll and belt replacement, which simplifies upkeep. Weighing only 12.2 pounds, it is lightweight and easy to transport, making it user-friendly for commercial settings. Conversely, the Shark offers an easy-empty dust cup that allows for quick disposal of debris without touching the mess, which can be particularly convenient for home users. While both vacuums prioritize usability, the Sanitaire’s maintenance features cater more to commercial users, whereas the Shark focuses on convenience for everyday home cleaning.
Size and Portability
The Sanitaire SC679K is designed with portability in mind, weighing just 12.2 pounds, which is advantageous for users who need to move the vacuum frequently across large areas. Its commercial-grade power cord extends to 30 feet, effectively covering a potential cleaning area of 4,680 square feet without needing to switch plugs often. The Shark, while not specified in terms of weight, is designed as a full-sized upright vacuum, which may be bulkier for some users. If portability and ease of transport are critical factors for you, the Sanitaire provides a clear advantage.
Filtration and Allergens
The Shark Upright Vacuum features an Anti-Allergen Complete Seal combined with a HEPA filter, which traps 99.9% of dust and allergens inside the vacuum. This feature is particularly beneficial for allergy sufferers, as it ensures that harmful particles are contained during the cleaning process. The Sanitaire SC679K does not mention specific filtration technologies, focusing instead on its bagged design, which may not offer the same level of allergen protection. For users concerned about indoor air quality and allergens, the Shark may be the preferable option.
Accessories and Add-ons
The Shark Upright Vacuum comes with additional tools designed for powerful pet hair pickup, enhancing its versatility for various cleaning tasks. This can be a significant benefit for pet owners or those with diverse cleaning needs. While the Sanitaire SC679K is primarily focused on commercial cleaning and does not emphasize additional accessories, it is built for durability and efficiency in high-demand environments. If you require specialized attachments for different surfaces, the Shark’s offering of bonus accessories is a noteworthy advantage.
Which should you buy?
Choosing between the Sanitaire SC679K Tradition Upright Commercial Bagged Vacuum and the Shark Upright Vacuum depends on your specific cleaning needs and budget. The Sanitaire is about 50% cheaper at $149.99 and excels in commercial-grade performance, ease of maintenance, and portability. However, the Shark, priced at $299.99, offers advanced features like superior suction, odor neutralization, and allergen filtration, making it ideal for home users, particularly those with pets. If you prioritize cost and reliability in a commercial setting, the Sanitaire is a solid choice. Conversely, for advanced home cleaning technologies and superior dirt pickup, the Shark stands out as the better option.
