Review on Roomba Dock Charging Contacts Home by Amanda Johnson

They have extended the life of my Roomba. Over time, the original contacts will wear out and Roomba will no longer charge well or at all. The only thing to watch out for is the front wheel. As it wears out, the front of Roomba moves closer to the ground, which in turn wears out the charging points. To replace these parts, you'll have to disassemble Roomba to the bone. Everything should come out, even the motherboard. It's not that hard, especially if you've ever built your own computer. This will most likely take a full day, so plan it for the weekend or holiday and not right after you get home from work. Since you're taking everything apart, do yourself a favor and take the time to clean up all the dust and dirt. he gathered in every nook and cranny. Grab a can under the car and a dust mask and get on with it.
