First, turn your Roomba upside down and clean the battery contacts on the base. Unplug the docking station and clean any dirt or debris off the contacts there too. If the contacts are rusty the rust will prevent the Roomba from charging properly. Get an emery board or fine nail file (I used the cardboard type as they are more flexible) and gently sand off any rust. This may get your Roomba charging again. As this is an earlier model Roomba the battery maybe due for replacement. Even a rechargeable battery doesn’t last forever. Later model Roomba’s have software that won’t let them take non-original parts but yours might not have this issue.

My Roomba gets “Charging Error 5” As suggest in the Roomba help section, I cleaned the contacts on the docking station and the Roomba and still got the error message.

I bought a new battery off Ebay and still got it, so I thought it must be a dodgy fake battery and I bought a long life lithium ion battery from Amazon…..and I still get Charging Error 5.

So its not the battery and its back to YouTube and that suggests an internal issue with the docking station and too unplug the cord from the docking station and put it directly into the Roombas charging port…. and still Error 5 but now I know its not the docking station.

So whats next? Any suggestions. The nearest repairer is over 3000k away so if I could fix it myself that would be great.
