I've been using this robot vac with no issues for a couple months. Suddenly, it stopped being able to find the charging station. Everything is plugged in and turned on. I have cleaned all the sensors. 

When I manually put it on the charging station, it charges just fine. 

However, it will not do the dust cleaning, I think because it still doesn't recognize that it's on ghe charging station.

I would really love to not have to recreate my maps, they are large and complex.
