The solid stream nozzle is primarily designed to deliver a concentrated and powerful jet of water, making it especially effective for targeting specific areas like cracks and crevices. This type of nozzle creates a focused stream that can penetrate narrow spaces, which is crucial for reaching pests or debris that may be hiding in those tight spots. The high pressure and direct application allow for a thorough cleaning or treatment, ensuring that any contaminants or pests are effectively addressed.

In contrast, options such as spraying wide areas or watering the garden generally require a different type of nozzle, designed to disperse water over a larger area rather than concentrating it into a single stream. Likewise, applying chemicals on plants would typically employ a nozzle that allows for a finer mist or spray to cover leaves evenly, rather than the direct jet provided by a solid stream nozzle.
