Under what circumstances will the robot recharge/self-clean?

The battery is less than 15 % during cleaning, or after cleaning , when the clean water tank is empty (the robot suspends the cleaning task and alarms the user to add water, and waits in place for 90s, if the user does not move after 90s, the robot automatically returns to charging base or starting position), when the sewage tank is full (the robot suspends the cleaning task and alerts the user to clean the sewage tank, waits in place for 90s, if the user does not move after 90s, the robot automatically returns to the charging base or starting position), When the robot cannot reach the designated area for cleaning, it will automatically enter the recharging state. The robot will automatically return to the charging base for self-cleaning and charging. In pause or standby state, short press the recharge button, the robot returns to the charging base to self-clean and charge. In pause or standby state, long press the recharge button, the robot returns to the charging base to charge without self-cleaning. Short press any button during the recharging process will suspend the recharging task . When the robot is on the charging base, short press the recharge button to start/cancel the self-cleaning task.
