520			_aThe pressurized underchassis washer is a cleaning system designed to remove dirt, mud, road salt, and other debris from the underside of vehicles. The prototype utilized several nozzles that sprayed water with high pressure while moving back and forth on a rail to cover the underchassis of the vehicle. The underchassis washer was built using PVC pipes, a C-channel rail, and a DC motor to move forward and backward. The control panel includes buttons for movement and an emergency stop for safety. This prototype offers a simple and cost-effective way to clean the underchassis of cars, helping to prevent rust and extend vehicle lifespan. It runs at a fixed pressure of 1400 PSI, which helped in cleaning effectively and evenly the underchassis of the four-wheeled vehicle. Based on the conducted testing, the cleaning time ranges from 54 seconds to almost 3 minutes in three laps, resulting in a thoroughly cleaned condition of the underchassis of the vehicles. The prototype is primarily designed for SUVs, MPVs, and utility vehicles, considering their ground clearance and size. The cleaning process includes soaping and rinsing to ensure the dirt is thoroughly removed. It is useful for personal car owners and car wash businesses. The prototype was evaluated by 30 respondents and obtained a general weighted mean of 3.83, indicating a very good descriptive rating
