This starter kit lets you conveniently use the high water gun and foam cannon. The high water pressure gun provides 5000PSI, higher than a standard washer sprayer with less than 2200PSI, which provides a simple way for car washing or wall cleaning. While, the foam cannon embraces high-quality sprayer assembly and comes with a large 35-ounce water tank with a wide bottle opening of 2.1” inches, allowing for fast and easy fill, and stands firmly with empty water.
