Dimension comparison
Design and Build Quality
The Avanti 18-Inch Dishwasher Machine is designed with compactness in mind, measuring just 18 inches wide. This makes it an ideal choice for smaller spaces like apartments and RVs. In contrast, the Sharp SDW6888JS features a larger 24-inch build, designed for more extensive kitchen setups. Both dishwashers are made of stainless steel, ensuring durability and a sleek appearance. However, the Avanti's compact design may better serve those with limited space, while the Sharp model, being larger, offers more loading options with its innovative third rack for flatware and utensils.
Washing Performance
When it comes to washing performance, the Avanti offers three wash options and six automatic cycles, including specialized modes such as Hi Temp and Sanitize. This variety is beneficial for users who require flexibility based on their dishwashing needs. On the other hand, the Sharp SDW6888JS takes it a step further with six wash cycles and seven options, including a Power Wash feature specifically designed to tackle heavily soiled items. Therefore, while both machines provide solid cleaning capabilities, the Sharp model is likely to deliver superior performance for challenging loads.
Noise Levels
Noise levels are a crucial consideration for any dishwasher, especially in open-concept living spaces. The Avanti operates at a quiet 53 dBA, making it suitable for use at any time without disrupting the household. Comparatively, the Sharp dishwasher boasts an impressively low noise level of 42 dBA, thanks to its Library Quiet technology. This makes the Sharp model about 21% quieter than the Avanti, providing a more peaceful kitchen environment during operation, which may appeal to those sensitive to noise.
Smart Features
The Sharp SDW6888JS stands out with its integration of smart technology, featuring compatibility with Alexa for voice controls. This modern convenience allows users to operate the dishwasher hands-free, enhancing the overall user experience. In contrast, the Avanti does not offer any smart features, focusing instead on straightforward usability with its top control LED display. For tech-savvy users or those who appreciate automation in their home appliances, the Sharp model presents a significant advantage.
Capacity and Loading Flexibility
In terms of capacity, the Avanti accommodates up to eight place settings, making it suitable for smaller households or limited dining needs. However, the Sharp dishwasher offers additional loading flexibility with its deep third rack, which is specifically designed for flatware and cooking utensils. This feature allows for a more efficient use of space, enabling users to wash more dishes in a single cycle. Thus, while both dishwashers have their merits, the Sharp model is likely more accommodating for larger families or those who frequently entertain guests.
Price Comparison
The Avanti 18-Inch Dishwasher is priced at $529.99, making it a more budget-friendly option compared to the Sharp SDW6888JS, which retails for $848.97. This price difference of about 38% might appeal to cost-conscious consumers looking for effective dishwashing solutions without breaking the bank. However, the investment in the Sharp model may be justified for those seeking advanced features, quieter operation, and enhanced washing performance.
Bestselling Status
In terms of popularity, the Sharp SDW6888JS ranks significantly higher on sales charts, holding a bestseller rank of 2213 compared to the Avanti’s rank of 5106. This distinction suggests that consumers may prefer the features and performance of the Sharp model, likely due to its innovative design and smart capabilities. A higher sales rank can be indicative of overall customer satisfaction and trust in the product's reliability and effectiveness.
Which should you buy?
Deciding between the Avanti 18-Inch Dishwasher and the Sharp SDW6888JS ultimately depends on individual needs and preferences. If you are looking for a compact, budget-friendly option that performs well in smaller spaces, the Avanti is a solid choice. However, if you prioritize advanced features, quieter operation, and superior washing performance, the Sharp model justifies its higher price point.
