Roombas are definitely awesome cleaning robots. Once in a while, after they have cleaned a lot, they need to be maintained in order to keep them in good shape and performing well.
Besides emptying the dust bin and removing hair from the brushes, it is also important to clean the entire Roomba mechanism once in a while in order to remove all the dust that could be clogging the poor robot's mechanisms.
In order to make this process easier, the nice people from
Geek.com put together a great time-lapse video, seen below, depicting this cleaning process. The video also features some cool 8-bit music so you are in for a treat!
