Robot not able return back to the docking unit

Robot is not able to determine power battery level and not stopping the operation to return back , as a result , finding the unit dieing with no power at any place , should have returned back and charged it self .

Also not able to detect papers on the ground as a result halting the operation, detection feature not working properly . I have this unit purchased not even month ago.

How to resolve the issue ?

I've noticed that same thing for some reason.The battery maintainer is not enabled or going.To know how to enabsplit so much for a smart robot.When you spend fifteen hundred dollars you expect to get the best

Mine does the same thing!

Anyone know where to purchase or how to refill the cleaning solution package?
