Scheduled cleaning cannot be carried out.
Is any power consumed if the vacuum cleaner always stays at the docking
station?
Is it necessary to charge the battery for 16 hours when the vacuum cleaner is
used for the first three times?
The power is insufficient during cleaning. After the vacuum cleaner returns to
the docking station for charging, it does not continue cleaning.
The vacuum cleaner cannot return to the docking station after partial cleaning
or after its position is moved.
The vacuum cleaner misses some areas when cleaning.
Solution
The power is insufficient. Scheduled cleaning will be started only when the
remaining power is more than 20%.
The power consumption is extremely low when the vacuum cleaner always
stays at the docking station. This helps to keep the battery in the best
performance.
The lithium battery does not have a memory effect. It can be used instantly
after it is fully charged. There is no need to wait 16 hours.
Check whether the main unit is in DND mode. The vacuum cleaner will not
continue cleaning in DND mode.
The vacuum cleaner will not continue cleaning if the main unit is manually
put back to the docking station.
The vacuum cleaner will re-generate a map after partial cleaning or after it is
moved far away.
If the main unit is far away from the docking station, the main unit may fail to
return to the docking station by itself. In this case, manually put the main
unit back to the docking station.
The wall sensor or cliff sensor may get dirty. It is recommended that you
wipe the sensors using a soft dry cloth.
