Why won't my roomba dock and charge

Hi I have a Roomba 561. I hadn't used it for a while and couldn't get the battery to charge when I went to use it. Now I have put a new battery in and it still wouldn't charge so I bought new charger. It now charges with direct connection. It still wouldn't dock. It would move into the station go back and forth and back or turn out of it . I cleaned all of the connectors and ordered a new docking station when that didn't work. Got new docking station todayband roomba does the same thing. Not sure what else to do. It all worked fine a year ago when I last used it.

Hope you can help ,

Thx

Kathy
