KM-B2 Bus Washer – Upgraded model with enhanced features. Automatically detects vehicle height to adjust brush arm position, offers multi-stage cleaning cycles, includes air-drying system, and features an intelligent control system.

I. Product Description

The KaiMeiLong KM-B2 Gantry Reciprocating 3-Brush Bus Smart Car Wash is purpose-built for mid-size coaches, city transit buses, and intercity buses, while also effectively cleaning box trucks and other heavy-duty large vehicles. Featuring a gantry reciprocating design, the system requires no external conveyor; drivers simply enter the frame at low speed to initiate the fully automated wash cycle. Equipped with three sets of covered flexible brush systems using premium imported materials that are gentle on paint, the unit integrates an intelligent computer control program with mirror-avoidance sensors. These sensors automatically retract brushes when approaching side mirrors, providing comprehensive protection for both the vehicle's bodywork and mirror assemblies to prevent scratches or damage. A multi-nozzle high-pressure water jet system works in tandem with an automatic dosing unit for high-activity car wash detergent, rapidly breaking down heavy mud, road grime, and oil. The combination of high-pressure water and enveloping bristles ensures thorough removal of stubborn dirt. The KM-B2 gantry bus washer supports continuous, uninterrupted operation with high automation standards and low core component failure rates, enabling high-volume cleaning within short timeframes while maintaining a compact footprint. Users can optionally add a heavy-duty air-drying unit designed specifically for large vehicles to address common pain points such as large surface areas, difficult manual drying, and water spots. This high-volume airflow system efficiently dries the entire exterior, including the paint and windows. Widely deployed in bus depots, long-distance passenger terminals, and logistics fleet parks, the KM-B2 3-Brush Gantry Car Wash is the industry-standard choice for fully automated large-vehicle cleaning in public transit and transportation systems.
