19. Can the robotic cleaner check whether the charging contact area on the bottom of the
machine is dirty or not? (Updated on March 18, 2019)
A: All series can check if the charging contact area on the bottom of the machine is dirty. If no
error is reported, it means that the cleaner is not particularly dirty, indicating that it's safe to
charge the cleaner. If dirt is detected, the cleaner will try to check it again several times before
reporting the error to remind the user to check the charging contact area. The cleaner will enter
standby mode during this process.
20. Q: What's the function of the water tank's position sensor? (Updated on March 27, 2019)
A: 1) It is used to trigger a voice reminder when the water tank is installed and removed;
2) After the water tank is installed, the user will be reminded whether the water volume is
sufficient or not during the cleaning process;
3) If the water tank has been installed in the cleaner for more than 6 hours at a time, the user
will be reminded once every day at 8:00/20:00. A message will be pushed to the user on the
app that reads "To prevent odor, it is recommended to remove the water tank, pour out the
remaining water and clean the mop.";
4) It records the service time of the water tank filter. The user will be reminded via the app to
replace the filter upon expiration of the service time.
