The KM-B1 bus car wash is designed for large coaches and buses, delivering powerful cleaning performance. Its oversized structure accommodates various large vehicles while ensuring stable and reliable operation.

1. Product Overview

Kaimelon KM-B1 Large Through-Body Computer Car Wash Equipment is a heavy-duty cleaning solution designed specifically for mid-size buses, long-distance coaches, and transit buses. It also accommodates freight trucks, sanitation vehicles, and other heavy engineering vehicles for complete exterior cleaning. The unit features a through-body pass-through design: vehicles enter at low speed under driver control—no external conveyor needed—to begin the full automated wash cycle. It employs a contactless high-pressure spray system that reduces acquisition and operating costs while eliminating risks of brush-induced paint scratches or side mirror damage. Equipped with three sets of high-pressure water jet nozzles and an automatic detergent dosing system with high-activity car shampoo, it rapidly breaks down and softens mud, grime, and oil on the vehicle surface. The 3D high-pressure water flow removes thick dirt in a single pass, delivering superior cleaning efficiency. This bus-specific car wash machine supports continuous, uninterrupted operation with high automation and low failure rates, capable of cleaning numerous vehicles per hour within a compact footprint. An optional heavy-duty air-drying unit for large vehicles can be added to eliminate manual drying challenges and water spot residue. Its high-volume airflow system thoroughly dries the entire vehicle surface. The KM-B1 contactless bus car wash machine is ideal for bus depots, long-distance coach stations, and passenger transport groups—and has become the standardized heavy-vehicle washing solution widely adopted by major public transit systems.
