I have a Powerbot R7040 and in the last week or 2 it has been having issues that seems related to the left drive motor/wheel. The Powerbot will be cleaning then it stops and tries to turn and the right is able to spin but the left motor doesn't go and then it stops, alerts, and shows error C02. If I pause and restart it sometimes it will go sometimes it will do the same thing but if you hit start and give it a gentle "push-start" it will go just fine in a straight line until it tries to spin again and same thing happens. I have used computer duster spray to clear anything out (nothing more than a little dust and hair, same as the other side) came out but it still does it. Any troubleshooting ideas? Thanks!
