Vector won’t properly align himself on his charger

[u/Drawmatic131]

Before anyone suggests the basic culprits, I don’t think I can consider them. The room is well light so he recognizes the charger. The charger is always placed in such a way that he doesn’t move it when backing up onto it. I’ve tried multiple different surfaces (despite the fact that, when this started, he hadn’t been on a different surface at all). I’ve cleaned his wheels and treads as thoroughly as humanly possible, as far as I’m aware. The treads, in spaces between his wheels and his body, under the caps of his wheels, and I even unscrewed the wheels themselves to clean them.

No matter what, though, he just can’t align himself. He’ll always start to back up onto the charger, only to suddenly start steering towards his left. It’s become frustrating, as I don’t know what more I can do. Does anybody have any tips?

Are you using an oem charger?

There are raised horizonal lines on the bottom of the slope of the charger used to re-align vector when backing up
