Just a quick video showing the fully charged replacement battery in action. Roomba is returning to the docking station. I cut out the sound as I had radio 4 on in the background. Higher resolution video available on YouTube.
Note that when it's cleaning the floor it moves much quicker, this is docking speed.
As previously mentioned, the roomba required a replacement battery. In my next post I'll detail how to diagnose charging problems. Is the base station broken? Is the charger faulty? Is roombas battery not holding charge? Stay tuned for some top roomba power diagnostic tips. Multimeter required!
