Q1: What should I do if the battery won't charge?

Troubleshooting: If the charger is disconnected, test the device to see if the green light is on. If the device displays a red light, check the charger for output voltage. Use a multimeter to check if the battery voltage is too low (less than 10V).

Solution: Replace the charger, try activating the battery, and then replace the battery.

Q2: Is the machine's suction weak?

Cause: Clogged float cage or clogged pipe.

Troubleshooting: Check the float cage for two floats and clean the pipes.

Q3: Are there water marks on the floor after cleaning?

Cause: The absorbent strips are cracked and aging, and the absorbent strips are wavy.

Troubleshooting: Visually inspect the caster height and tailgate for deformation.

Solution: Replace the absorbent strips, adjust the caster height, align the sheet metal, and replace if necessary.

Q4: The machine isn't producing water?

Cause: Damage to the solenoid valve, clean water line, or water valve switch.

Troubleshooting: Check whether water flows after unplugging the water pipe upstream of the solenoid valve. Check whether the solenoid valve input line has 24V voltage. Check whether the transparent clean water pipe is free of foreign matter or scale. Check whether water flows from the water pipe upstream of the valve. Check whether the water valve switch opens and closes normally.

Solution: Replace the solenoid valve, clean the clean water line, and replace the water valve switch.

Q5: The machine won't push.

Cause: Are the brushes on the brush plate worn and shortened? Is the brush plate's opening worn? Is the brush plate not rotating? Is the brush plate motor not working?

Troubleshooting: Visually inspect or use a multimeter to check the motor's circuit output.

Solution: Replace the brush plate, replace the brush plate buckle, check the brush plate motor circuit, and replace the brush plate motor if necessary.

Q6: Motor not working?

Cause: Damaged contactor, fuse, or switch.

Troubleshooting: After the switch is turned on, there is no 24V input to the contactor. Is the fuse burnt out? If the light does not illuminate after turning the switch on, the motor will work after swapping the switch plug.

Solution: Replace the contactor, fuse, and switch.
