Compact and mid-size ride-on floor scrubbers are mainstream models in the commercial and industrial cleaning equipment market. Typically featuring a cleaning path width of 600–1,000 mm and 24V/36V electrical systems, they are widely used in medium- to large-sized factories, logistics warehouses, airports, and high-speed railway stations. Compared with basic walk-behind scrubbers, these machines have higher power requirements and more sophisticated electrical systems. Typical configurations include seat safety switches, foot-pedal accelerators, electromagnetic brakes, electric actuators for brush deck and squeegee lifting, water flow adjustment, recovery tank full detection, solution tank low-level detection, tilt protection, collision protection, and fault diagnostics. Optional 4G connectivity enables IoT-based monitoring and management. These increasingly complex applications place significantly higher demands on controller integration, system reliability, fault diagnostics, and CAN bus communication capabilities.
