Model 561 charges fine (well, it looks like it is charging fine), but when I try to use it, it stops immediately and tells me to charge it -
Hi, have you replaced the battery since you had this robot? Usually, batteries can last up between 1 to 2 years with proper care.
If you have not replaced the battery, we would suggest you to do so, as it seems the battery you are using doesn’t have enough capacity left to run the robot.
You can find Roomba 500 batteries on our website, here.
