What household device, originally called the “Whirlwind” when it was patented by Ives McGaffey in 1869, later became a common cleaning appliance?

Introduction / Context:

Many everyday household appliances had different names or early versions before becoming the familiar products we know today. This question asks about an item originally called the Whirlwind when patented by Ives McGaffey in 1869. Knowing that this name referred to a particular cleaning device helps you understand the early history of household technology.

Given Data / Assumptions:

• The inventor is Ives McGaffey.
• The original name of the invention was the Whirlwind.
• The patent date is 1869.
• The options list common household appliances used for mixing, washing and cleaning.

Concept / Approach:

The Whirlwind was an early mechanical vacuum cleaner invented by Ives McGaffey. It used hand powered mechanisms to generate suction and remove dust from floors. Although bulky and less efficient than later electric models, it was an important step toward the modern vacuum cleaner. Other devices such as blenders, electric mixers and dishwashers were developed later and serve different functions in the kitchen and laundry, not in floor cleaning by suction.

Step-by-Step Solution:

Verification / Alternative check:

Histories of cleaning technology mention McGaffey s Whirlwind as one of the earliest patented vacuum cleaners. They describe its hand cranked operation and limitations compared with later electric vacuums. These sources do not associate him with blenders, washing machines or dishwashers, which confirms the connection between Whirlwind and vacuum cleaner.

Why Other Options Are Wrong:

A blender is a kitchen appliance used to mix and puree food and drinks; it is usually associated with later twentieth century inventors.

An electric mixer also deals with food preparation and does not fit the 1869 Whirlwind patent or McGaffey s work.

A washing machine cleans clothes using water and mechanical agitation and has its own separate development history.

A dishwasher cleans dishes and cutlery and is unrelated to McGaffey s invention.

Common Pitfalls:

Because several household appliances involve spinning or swirling motion, some learners may mistakenly connect the name Whirlwind with washing machines or blenders. The key is to remember that McGaffey is linked with early vacuum cleaner technology and that Whirlwind referred to moving air and dust removal, not to water based washing or food processing.

Final Answer:

The item originally called the Whirlwind and invented by Ives McGaffey in 1869 was the vacuum cleaner.
