- Test: Push the bumper with your hand to see whether it is stuck. Perform a BIT test (within 3 minutes of starting up the robot, press and hold the Charge button and quickly press the Power button 5 times at the same time) to determine whether it is the left or right bumper that is malfunctioning.
- Based on the test results, unplug the wire bundle terminal at the motherboard end of the downward front bumper assembly on the faulty side and then reinsert it. Perform a BIT test to determine whether it is still malfunctioning. Replace the downward front bumper component on the faulty side. Replace the motherboard.
Error 2: Please move the robot to a new location and restart it Error 2
Symptomen
- When the robot starts cleaning on a flat surface, the voice prompt announces "Wheels suspended. Please move me to a flat surface."
Oplossingsrichting
Wheels suspended
Reparatiestappen
- Test: Perform a BIT test (within 3 minutes of starting up the robot, press and hold the Charge button and quickly press the Power button 5 times at the same time) to determine whether the drive wheels are able to rotate normally.
- Check whether there are foreign bodies stuck in the wheel Based on the test results, replace the corresponding drive wheel component on the faulty side.
Error 3: Please clean the cliff sensor, move the robot away from the cliff and restart. Error 3
Symptomen
- When the robot starts cleaning on a flat surface, the voice prompt announces "Please clean the cliff sensor."
Oplossingsrichting
Cliff sensor malfunction
Reparatiestappen
- Test: Clean any dust from the sensor before testing. During the BIT test (within 3 minutes of starting up the robot, press and hold the Charge button and quickly press the Power button 5 times at the same time), test the cliff sensor to determine whether it is faulty.
- Based on the test results, unplug the wire bundle terminal of the downward front bumper assembly on the faulty side and then reinsert it. Perform another BIT test to determine whether it is still malfunctioning. Replace the downward front bumper component on the faulty side. Replace the motherboard.
Error 4: Please remove the main brush to clean the bristles and bearings Error 4
Symptomen
- After the robot starts cleaning, the voice prompt announces "Main brush error, please check and clean it."
Oplossingsrichting
There may be foreign bodies entangled in the main brush.
Reparatiestappen
- Test: First remove the main brush to see if there are foreign objects wrapped around the shaft, remove the foreign objects and perform the BIT test (within 3 minutes of starting up the robot, press and hold the Charge button and quickly press the Power button 5 times at the same time), then perform a brush roller test to see if the brush is rotating normally.
- Check whether there are foreign bodies stuck in the main brush bearing. Replace the main brush gearbox assembly. Replace the motherboard assembly. This error may occur when using the robot on carpets. Advise the customer to not use the robot on thick carpets.
Error 5: Please remove and clean the side brush Error 5
Symptomen
- After the robot starts cleaning, the voice prompt announces "Side brush malfunction. Please check and clean the side brush."
Oplossingsrichting
There may be foreign bodies entangled in the side brush.
Reparatiestappen
- Test: First check the side brush and remove any foreign bodies. Perform a BIT test (within 3 minutes of starting up the robot, press and hold the Charge button and quickly press the Power button 5 times at the same time), then perform a side brush test to see whether the side brush is rotating normally.
- Remove the side brush; check whether there are foreign bodies entangled in the side brush, and then check whether the fault is eliminated after cleaning. Replace the side brush gearbox assembly. Replace the motherboard.
Error 6: Please check whether there are foreign bodies caught in the main wheel, move the robot to a new location and restart Error 6
Symptomen
- During cleaning, the voice prompt announces "Right drive wheel error. Please check for debris and clean the drive wheel." or "Left drive wheel error. Please check for debris and clean the drive wheel."
Oplossingsrichting
The robot may be stuck or there may be foreign bodies caught in the main wheel.
Reparatiestappen
- Test: According to the prompt, check whether there is a foreign body in the wheel on the faulty side.
- Remove any foreign bodies from the wheels. Replace the faulty wheel module.
