Design and Build Quality
When it comes to design and build quality, the Avanti 18-Inch Dishwasher Machine and the Sharp SDW6757ES Slide-In Dishwasher each present unique advantages. The Avanti model is compact at just 18 inches wide, making it ideal for small spaces such as apartments or RVs. It features a stainless steel finish and operates quietly at 53 dB, which is suitable for environments where noise might be an issue. In contrast, the Sharp model, measuring 24 inches wide, offers a more robust build with a sleek stainless steel finish that complements other appliances. Its premium smooth glide rails allow for easy rack movement, enhancing user experience.
Washing Performance
The washing performance of the two dishwashers differs significantly. The Avanti model provides three wash options and six automatic cycles, including specialized settings like Sanitize and Eco half-load mode, ensuring a thorough clean for up to 8 place settings. On the other hand, the Sharp dishwasher boasts six washing cycles and seven options, including a Power Wash Zone designed for tougher cleaning tasks. Its soil sensors optimize washing cycles automatically, which may lead to more efficient cleaning. This capability, combined with the heated dry option, suggests that the Sharp model may handle larger and more challenging loads more effectively.
Capacity and Loading Options
In terms of capacity, the Avanti dishwasher accommodates up to 8 standard place settings, making it a suitable choice for smaller households or occasional use. Its design includes a silverware basket and a cup tray, enhancing loading flexibility. In contrast, the Sharp dishwasher, while also catering to various load sizes, features an adjustable third rack, which provides additional space and options for loading. This versatility can be particularly beneficial for families or those who frequently entertain guests, allowing for more efficient use of the machine's capacity.
Noise Levels
Noise levels are an important consideration for many buyers. The Avanti 18-Inch Dishwasher operates at a quiet 53 dB, which is relatively low and suitable for open living spaces or small apartments. The Sharp SDW6757ES, however, takes the lead with a library-quiet rating of 45 dBA, making it one of the quieter options available. For users who prioritize a peaceful environment, especially during late-night washing cycles, the Sharp model may be the preferable choice.
Energy Efficiency
Both dishwashers offer energy-efficient features, but they approach this in different ways. The Avanti model includes an Eco half-load mode, which allows users to run smaller loads without wasting water or energy. This feature, combined with its compact size, may contribute to lower overall utility costs for smaller households. The Sharp dishwasher, meanwhile, emphasizes its Half Load feature that minimizes water and energy consumption, making it beneficial for users who often wash smaller loads. While both models are designed to be energy conscious, the effectiveness of their respective features can vary based on usage patterns.
Price Point
Price is a crucial factor for many consumers, and here the Avanti 18-Inch Dishwasher comes in at $529.99, making it about 17% cheaper than the Sharp SDW6757ES, priced at $598.97. This price difference may be significant for budget-conscious buyers looking for reliable performance in a compact design. Both models offer unique features that justify their price points, but the Avanti’s lower cost may appeal to those who need a basic and effective dishwasher without the additional bells and whistles.
Customer Reception
Customer reception can provide insight into the overall satisfaction associated with each model. The Avanti dishwasher has a sales rank of 5106, indicating a steady presence in the market, while the Sharp model has a better sales rank of 2988, suggesting a higher level of popularity and potentially more favorable customer feedback. This may reflect the Sharp’s enhanced features and performance capabilities, which could justify its higher price point.
Which should you buy?
Choosing between the Avanti 18-Inch Dishwasher and the Sharp SDW6757ES Slide-In Dishwasher will largely depend on your specific needs and budget. If space is a premium and you require a compact washer that is budget-friendly, the Avanti model is an excellent choice with its reasonable price and solid performance for smaller loads. However, if you prioritize quiet operation, advanced cleaning features, and a more robust capacity for larger households, the Sharp model may be worth the additional investment. Ultimately, both dishwashers offer distinct advantages that cater to different user preferences and lifestyles.
