Neabot Nomo robot back to station issue

I have new robot Neabot Nomo recently. When starting clean it works very perfect, robot creates new map perfectly and cleans good.
returns to docking station after cleanup or recharged.

A bit regret is the robot can’t find the way back to base if it runs too farway

I’ve purchased it from this gadgetplus, Do you have any advice?

I didnt know there was a homey app for that brand. :thinking:
