6.1 Fault description Host failure description

The host cannot be charged The host and the charging pole of the base station are not in full contact. The power of the charging base station is turned off, and the power switch of the main unit is turned on, resulting in power consumption. Make sure that the main unit is fully connected to the charging pole piece of the charging base station. When the main unit is not performing work, it is recommended to keep it in a charging state, so as to better carry out the next work. Stuck when host works The main unit is hindered by entanglement of scattered wires on the ground, drooping curtains or carpet fringes. The host will try various methods to get out of trouble independently. If it fails to get out of trouble, it is recommended to help manually. The cleaning is not completed, the host returns to charge The main unit can sense the lack of power when it is working, and it will automatically return to charging. Charge the host. Wooden floors, ceramic tiles and other flat ground hosts work at different speeds and for different periods of time. The working time of the host varies with the complexity of the room, the amount of garbage and the cleaning mode. The host power switch is not turned on, and the host cannot work by itself according to the agreed time when it is turned off. Turn on the host power switch. The host does not automatically clean according to the scheduled time The power of the main unit is low. The host components are clogged and entangled with garbage. When the host is in standby, it should be kept charging on the charging stand to ensure that it has sufficient power to work at any time. Turn off the power, clean the dust box and turn the bottom of the host up. Clean each part separately. When the main machine is working, there are phenomena such as missed scanning, chaotic routes, deviation, and irregular and untidy display of the cleaning Figure on the APP side. It may be that when the main engine climbs small steps, thresholds, and door bars, the driving wheel and the ground slip, which affects the main engine's judgment on the working environment of the whole house. It is recommended to close the door to the area and clean the area separately. The main unit has the function of independently identifying single rooms, and it will return to the starting point after cleaning, so please feel free to use it. Work on freshly waxed, polished floors or smooth surface tiles, resulting in less friction between the drive wheels and the floor It is recommended that you wait for the floor wax to dry before cleaning. Wires, slippers and other objects placed on the ground affect the normal operation of the host Before the host works, please sort out the scattered wires, slippers and other objects on the ground to reduce the scattered items on the ground as much as possible.
