1、Great Performance: This product is a cordless rechargeable underwater intelligent cleaning robot, which can filter and clean the bottom of the pool without changing the pool water. It has the advantages of regular path, long endurance and great cleaning effect. In addition, it also adds intelligent side stop, status prompts and other functions to make it more user friendly. 2、Charging Prompt Function: When charging, the red lights blink. When the battery runs out, the green indicator is always on and the buzzer calls for 1 minute. 3、Power Switch Function: Long press the bottom of the cleaner host (power switch) for 2 to 3 seconds, the indicator light, motor, buzzer and other hardware will automatically detect, indicating that the cleaner enters the normal working state. In the startup state, long press the power switch for 2 to 3 seconds to turn off the cleaner. 4、Water Resource Exploration Function: When the robot does not detect the pool water, the power indicator flashes and the buzzer sounds. It needs to be in the pool within 1 minute (otherwise it will close on its own). When the robot detects water in the pool, the buzzer will stop sounding, and the work light and battery light will flash simultaneously or alternately. 5、Water Delay: After the robot enters the water spraying mechanism, it starts up 30 seconds later, which helps the robot to land smoothly to the bottom of the pool and does not roll when sinking. 6、Battery Indicator Function: When the power is sufficient, the green indicator flashes, when the power is insufficient, the red indicator flashes. When low, the battery base stops and automatically turns off. After that, the power supply red lights blink for 1 hour. 7、Adaptive Movement Speed: Cleaning will automatically adjust the movement speed according to the current terrain. For a certain slope of the pool can be very great adaptability, for flat pool can minimize power consumption, prolong the endurance. 8、Automatic Reversing Function: When the robot touches the pool wall, it will automatically reverse after 4 seconds. When it needs to be repaired, the robot will automatically lean against the wall. 9、Cleaning Self Service Parking Function: When the filter system of the cleaner is too dirty and needs to be cleaned, the cleaner will automatically approach the wall, INSPECT's red lights will flash and WORK's green light will be extinguished. The duration of wall cleaning depends on the actual cleanliness of the pool. It maximizes the actual cleaning effect of the cleaning machine and avoids the machine in a long time. It also prevents the filtration system from being completely blocked, making it difficult to retrieve water anywhere in the pool. 10、Self Parking Under Power: When the internal battery is low, the cleaner will automatically lean against the wall, the power red lights will flash, the WORK green light will go off, and it will automatically turn off the power when the power level falls below a safe level. Can avoid serious battery loss and damage to battery life and avoid clean battery loss, stop in the pool and not easy to catch.
