I'm far from a Roomba expert and only clicked on your question out of curiosity given my background and as there was a similar question earlier Id passed. A little research... Roomba NiMh battery pack is 14.4 v full charge. NiMh charging is a bit complicated, suffice to say it will eventually go well over 16V. I would expect the charging station to have an initial charge voltage in excess of 12.5V. What I don't know is if its always on or waits to see if a load (roomba) attaches and then turns on its output. So if you measured the power, contacts on the charger with a voltmeter and you get better than 12V likely its good, but really need to know what the voltage is when Roomba (with nominal battery pack) is docked. Its likely the battery pack in the Roomba has a bad cell and will need replaced. You could measure the battery voltage but likely its low from not taking a charge. If its 14+ then the charger is working and the Roomba is misreporting.

As with all vacuum cleaners, the unit can get dirty inside. There is a sensor under the brush unit that hears dirt hit it and triggers the circular cleaning action. This sensor looks like a dime sized hole with a bronze piece inside. Also the unit can be disassembled by removing 4 screws on the bottom and removing the top.
