- Newly Upgraded Dual-Cleaning Modes: This pressure washer undercarriage cleaner first uses the included foam cannon to spray thick foam, breaking down stubborn oil stains and grime; then, its 4000 PSI high-pressure water flow blasts away sediment, dirt, and debris—keeping your chassis clean, rust-protected, and extending vehicle life.
- Small Wheels, Big Reach: Meticulously designed with smaller wheels, this under carriage pressure washer lowers the overall height—easily sliding under low-slung chassis and hard-to-reach areas. No need to jack up your car! It fits more vehicle types (sedans, SUVs, trucks) than traditional models, delivering wider compatibility for all your cleaning needs.
- Thoughtful Configuration: The included foam blaster isn't just for chassis cleaning; it can also be used with a black nozzle and wands to clean the car's surface. The undercarriage cleaner is also equipped with a car wash mitt. Whether cleaning the chassis sediment or carefully wiping the body surface, it can be easily handled to achieve a full range of cleaning care for the vehicle.
- Crucial Operating Guidelines: Attention! The working pressure range of our under car pressure washer attachment is 1500 PSI to 4000 PSI. For optimal performance, we recommend a pressure of 2500 PSI or higher. Ensure that your equipment's working pressure is above 1500 PSI to guarantee effective cleaning.
- Important Usage Tips: If you want to use both the underbody pressure washer attachment and foam cannon, please use the large-aperture BRASS car undercarriage washer nozzle (included) to prevent leakage at the connection. Small-diameter stainless steel nozzles are not suitable for this combination—always use the correct nozzle for safe, leak-free operation.
