I don't really know but to me it doesn't sound right for a 2 week old machine. I would want a better answer. I found this comment to a review, although it's from the 9550 I have, I found the comment interesting. I would never do what that guy did with his cord because Polaris or the seller should take care of it because it is under warranty, but it might not hurt to take it to where you bought it if locally so they could look at the cord, or contact Polaris again and talk to their tech support or email. The email I found listed was [email protected].I've had my robot for a couple weeks. I did contact Polaris and this was their response: "No need to worry we have seen this before and it should not affect the cleaner operation."
The comment about the cord is the 1st comment here: Review with cord comment at Amazon
