Neato robovac xv21 "clear my path"

My Neato robot vac xv-21 keeps saying clear my path a lot more than it used to. There’s nothing in its path. It seems to have a problem moving on even a short piled carpet.
I’m wondering if I should purchase new wheel Motors. I just recently replaced both batteries.
Any ideas? Thank you.

Hi,

Maybe the sensors needs a good cleaning:

Try cleaning them and let me know how it goes.

I cleaned them and still not working so do the sensors need replacing and how to check them
