Does Anyone Know Why My Irobot Roomba Doesn’t Seem To Charge? Didn’t Use It For A Few Months.?
When I place it back on base to charge, red charging light starts glowing and then turns green an hour or so later, indicating that it has fully charged. But when I start it, it runs for one second then it stops, and its power button turns red again like it was never charged at all. I tried cleaning the charging contact points to no avail. What could be the problem?
Reset the Roomba charging system. Do this by removing the Battery and holding down the “power” button for at least 5 seconds. Then reinstall the Battery.
Plug the Charger into Roomba (avoid using the Home Base® if you have one so as to ensure the Roomba’s charging cycle is not interrupted.)
Charge the Battery until the Roomba Power light is solid green and keep the Roomba on the Charger for an additional 72 hours (3 days). Note: Do not interrupt this charging cycle.
In Max mode, run the Roomba for one complete cycle without a Home Base present, to deplete the battery. Keep track of the runtime and if it has improved, repeat steps 3 and 4 a few times. If your Roomba does not have Max mode, run several Clean cycles until Roomba stops and plays the “dead battery” song.
The batteries are dead, those sweepers are nice BUT the batteries will not last. Sorry but new batteries are needed or if still under warranty send it back.
Simply change the battery if not used for a long time the acid in it is dead and needs to be replaced.
My advice is simply use it for an hour a week and recharge it every month.
Just like your car if you do not use it for a long time it will not start untill you jump start it.
