Variable nozzle is a type of attachment for vapes that allows changing the shape and intensity of the water stream. With this attachment, you can switch between a wide water jet for cleaning larger and more sensitive surfaces such as house facades, patios or vehicles and a narrow water jet for removing stubborn dirt such as grease stains, baked-on dirt, moss or lichens. The variable nozzle thus provides greater control and flexibility in cleaning different types of surfaces and dirt without the need to change nozzles or attachments.
