Which advertising technique is exemplified by the phrase "Try the new Remington VicVac. It treats stains like dirt."?

The phrase "Try the new Remington VicVac. It treats stains like dirt." demonstrates the technique of Comparative Advertising. This form of advertising explicitly compares one product with another or with a general category of products to highlight its advantages. In this case, the statement suggests that the VicVac is particularly effective at handling stains by likening them to dirt, implying a superior stain removal capability.

In this message, the implication is that if the device treats stains as easily as it treats dirt, it must be an effective tool for cleaning. This appeal serves to position the product favorably against competitors by emphasizing its unique feature in a memorable way. The use of a common association with dirt allows consumers to relate better to the product's effectiveness, enhancing the overall persuasive quality of the advertisement.

Other approaches, such as Sophistical Formula, Emotional Appeal, or Technical Jargon, do not focus on comparative advantages in the same manner. Each of those methods serves a different purpose in advertising, but in this context, the comparison to dirt stands out as the core element of persuasion.
