Which cleans better: an ultrasonic dishwasher or a traditional dishwasher?

This is a critical issue, with the core conclusion being: Traditional dishwashers (high-pressure spray type) perform better in scenarios involving heavy grease and large volumes of dishes, while ultrasonic dishwashers excel in scenarios involving delicate, small quantities, or fragile items.

Key Dimensions for Cleaning Effectiveness Comparison

Heavy Grease Removal: Conventional dishwashers outperform. High-pressure spraying + high temperature (60-70°C) + specialized detergent rapidly strips stubborn grease and burnt-on residues from frying pans and baking trays without manual pre-treatment.

Precision Cleaning: Ultrasonic dishwashers deliver greater accuracy. High-frequency vibrations generate microscopic bubbles that penetrate crevices in tableware, baby bottles, pacifiers, and jewelry to remove residue without damaging surfaces.

Fragile Item Compatibility: Ultrasonic dishwashers offer greater safety. With no physical impact, they gently clean glassware, ceramic carvings, and delicate components, avoiding breakage caused by the spray pressure of traditional dishwashers.

Batch Cleaning Efficiency: Traditional dishwashers are more efficient. They can accommodate multiple place settings (8-16 sets) at once with a fixed cleaning cycle. Ultrasonic dishwashers are typically compact models with lower single-load capacity, better suited for small batches.

Key Usage Considerations

Traditional dishwashers require specialized detergents and soft water; otherwise, limescale may form, compromising cleaning effectiveness.

Ultrasonic dishwashers have limitations with grease thickness. Heavily greasy items require preliminary rinsing to ensure thorough cleaning.
