KM-B3 Tunnel Bus Washer with continuous cleaning mode and multi-vehicle capacity delivers exceptional efficiency and automation, ideal for transit operators.

I. Product Overview

Kaimelon KM-B3 Bird's Nest Tunnel Intelligent Bus Wash System is custom-developed for city buses, long-distance coaches, and large passenger vehicles, while also adapting to cleaning operations for various large transport trucks such as box freighters. The entire unit features a straight-through tunnel design, allowing drivers to enter the system at low speed without external towing equipment to complete the full automated washing cycle. Equipped with four sets of imported flexible brush units in a 360° wrapping configuration, this model supports optional top-mounted horizontal brushes for enhanced cleaning. Paired with a fully intelligent PLC computer control system featuring an automatic rearview mirror avoidance sensor, the brushes automatically retract during the scrubbing phase to protect original paintwork and body accessories from scratches. The system integrates a high-pressure water jet spray system across all zones, working in tandem with automatically dosed high-activity car wash detergent to rapidly break down and soften attached mud, asphalt, and road oil. Combined with the multi-directional brushing action and high-pressure rinsing, it delivers superior cleaning performance for entire vehicles. Designed for continuous, non-stop pipeline washing, the KM-B3 boasts exceptional daily throughput—capable of cleaning up to 80 large vehicles per hour. With high automation standards, low core component failure rates, and compact footprint planning, it offers reliable operation. Standard equipment includes an integrated high-volume air-drying unit that effectively addresses industry pain points related to large bus surface areas, inefficient manual drying, and persistent water spots. Optional upgrades include an undercarriage auto-rinse module and a water recycling treatment system, enhancing water conservation and environmental benefits. Widely deployed in major coach terminals, bus depots, and logistics fleet parks, the KM-B3 tunnel-style four-brush car washer has become the preferred high-efficiency solution for China’s public transit and passenger transport systems.
