>>> How to set nozzle angle and cleaner route?
--- The nozzles of the pool cleaner are marked with angles (0°-40°). Adjust the nozzle by turning it to control the cleaner route. The vacuum cleaner moves in an approximately straight line when the nozzle angle is 0°. The pool cleaner moves in a more curved line at a larger angle from 0°-40°.
Setting I: default setting: 0°-20°, for most of pools.
Setting II: 0°-40°, when setting 1 does not manage a full coverage of the pool.
Setting III: 20°-20°, for round pools
Tips:
I.Please read the user manual before using it for the first time.
II.Please charge fully prior to first-time usage.
III.The robot will start running after twenty seconds of putting it into the pool. It is for pools with bottom slopes of less than 15 degrees and thus it will not climb walls and steps. 
IV.The charging port must be dried before charging and the machine should be placed in a dry and ventilated place
