Repair method

● If it is a rough carpet floor, the resistance of the machine forward is too great, put the machine on the floor environment and try it.

● Unplug the left and right wheels and start the machine to check if there is any such bad phenomenon. If there is, it means that there is a problem with the motherboard and the motherboard needs to be replaced.

4 Does not boot

Fault description

It can't be turned on by pressing the power button.

Repair method

● The machine has been left for too long and the battery is dead, so you need to use a charging stand or adapter to charge it.

● Please check whether the battery cable and the connection cable of the face shell are loose or fall off.

● If the machine is switched on and off frequently, please check whether the key switch is damaged.

● When none of the above reasons are found, the motherboard needs to be replaced.

5 No shutdown

● If the machine is switched on and off frequently, please check whether the key switch is damaged.

● Please check whether the connection cable of the face shell is loose or falling off

● If an abnormality is not detected, the main board needs to be replaced.

6 The brush does not turn

Fault description

The main brush rotates, but the side brush does not rotate;

the main brush and the side brush do not rotate

Repair method

● Check whether the main brush is rotating, if the main brush is rotating, then check whether there is any foreign matter entangled in the side brush

● If neither the main brush nor the side brush can be rotated, loosen the screws of the main tooth box a bit and see if it starts to rotate. If it still cannot be rotated, only replace the main tooth box.

7 The fan/brush keeps rotating regardless of whether it is turned on or off

Fault description

 The fan/brush keeps running after shutting down

Repair method

● Replace the motherboard

8 The left/right wheel does not turn

Fault description

After the machine is started, the left / right wheels do not rotate, and the main brush / fan works normally.

Repair method

● First check whether there is any foreign matter stuck on the left and right wheels and whether the socket is loose.

● If there is only one wheel that does not turn, switch the left and right wheel sockets to start the machine and check whether the machine still does not turn on the previous wheel. If it is, it means that the wheel that does not turn is broken and the wheel needs to be replaced. If not, the motherboard needs to be replaced.

● The machine starts to move diagonally to one side, stops after walking or hits a wall and then pauses, indicating that the motherboard is broken and the motherboard needs to be replaced

● Open the charging base and let the machine switch to find the charging base mode and run, and see if the machine can automatically turn when looking for the charging base. If it can turn, it means the problem is with the remote control. If it can't turn, it means the receiver of the machine has a problem. Replace it. 

10 The machine does not charge

Fault description

The buttons on the remote control do not work after turning on; the machine does not circle when looking for the charging station

Repair method

● When the remote control does not work, if you find the charging cradle normally, it means that there is a problem with the remote control itself. Check whether the battery is charged and the battery voltage is normal. A dead battery needs to be replaced with a battery of the same specification. If the machine does not turn in a circle when looking for the charging station, it means that the receiving head of the button board/display board of the machine is bad, and the button board or receiving head needs to be replaced.

● The machine is controlled by remote control only after it is turned on manually, and cannot be controlled by remote control when it is turned off manually

11 The machine cannot be charged after being left for too long

● If the running machine suddenly becomes louder, observe whether the machine enters the clockwise fixed-point cleaning mode. If it enters the fixed-point mode, it is a normal phenomenon and will automatically recover after a period of time.

● If the machine has a sharp sound in the automatic cleaning mode, please check whether the dust box is installed, and check whether the brush and dust box are too dirty.

● If there is a serious abnormal noise, turn the machine into automatic charging mode and run the machine to observe whether there is any abnormal noise. If there is any abnormal noise, it means that it is the abnormal noise of the main brush box. Check whether there is any foreign matter on the brush wheel. If there is no abnormal noise, it means that the fan is abnormal. Check whether the fan is stuck with foreign objects, otherwise the fan needs to be replaced.

21 The fall prevention of the machine is ineffective or not working

Fault description

The running machine occasionally falls off the steps or pauses at the edge of the steps and alarms with a red light

Repair method

● First of all, make sure that the height of the step must be greater than 8CM.

● Please check whether the sensor at the bottom of the machine is too dirty or obstructed. The smooth or highly reflective parts of the machine may cause deterioration of the anti-drop function.

● Check whether the machine is working under strong sunlight. Please do not stack fragile objects under the table or steps cleaned by the machine to prevent the machine from falling under the influence of the environment.
