This device facilitates the application of soap or other cleaning solutions directly through a standard garden hose. It typically consists of a reservoir to hold the cleaning agent, a mechanism to mix the solution with water flowing through the hose, and an adjustable nozzle to control the spray pattern and concentration. An example of its use would be applying insecticidal soap to plants or washing a car with diluted detergent.
The utility of such a system lies in its convenience and efficiency. It allows for quicker and more even distribution of cleaning agents compared to manual application methods. Historically, these devices have evolved from simple siphon-based systems to more sophisticated designs incorporating pressure regulation and adjustable mixing ratios. This evolution reflects a growing demand for efficient outdoor cleaning and maintenance solutions.
