>>> 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.
