The HOTO 20V Pressure Washer Pro was designed to meet the needs of urban users, providing portability, ease of use, and unrestricted site use. The design team focused on enhancing the user experience by innovating the pump material and optimizing the center of gravity, which reduces user fatigue. Additionally, it can work with alternative water sources, such as a bucket, through its self-priming function to ensure that water access is not a limiting factor. The 5-in-1 nozzle has a rotating head, which makes it easy to switch between five different spray arrays.
