A Please check if the clean water tank is empty or the recovery tank is full. The machine features electronic sensors that automatically shut down the unit to protect the motor in these situations. Normal operation will resume once the water is replenished or the recovery tank is emptied.

A Please check if the machine is in reverse mode. The brush motor automatically cuts off when reversing as a safety feature of the smart control panel; rotation will resume automatically when moving forward.

A There is no need to worry. Liangcheng floor scrubbers are equipped with a smart dual-system and a self-recovery function that automatically detects faults and attempts to resolve them. In most cases, the machine recovers on its own without requiring repairs.

A Please check if ECO mode is enabled; activating this feature can double the runtime. We also recommend using fast-charging Lithium Iron Phosphate (LiFePO4) batteries, which charge in just 3-4 hours, significantly boosting operational efficiency.

A Please check if the recovery tank water-level sensor is functioning correctly (this prevents water from entering the motor). Also, ensure the squeegee is level-the all-aluminum squeegee assembly includes a built-in level indicator for adjustment-and check if the squeegee blades are worn and need replacement.
