Cause and remedy
1. Wi-Fi signal is weak. Make sure that the Wi-Fi signal in
the location of the robot vacuum cleaner is strong.
2. There is a cutoff in Wi-Fi connection. Please reset
Wi-Fi, download the latest mobile application and try
again.
3. Password is not entered correctly.
4. The router used is a model that operates in 5G
frequency band (this robot vacuum supports the 2.4G
frequency band only).
Charging level is low. Timed cleaning can only be started
when the charge level is higher than 20%.
The vacuum cleaner consumes very little amount of
power while it is in the charging dock; this feature allows
to keep the battery performance in the best level.
