While on her auto cleaning mode, bObi automatically returns to her charging station when her battery reaches 15% battery capacity.
You can also ask bObi to refuel at any time by pressing the JUICE button on her cover or on her remote.
If bObi is having trouble docking to her charging station, you may need to place it in a more central, accessible location. Make sure bObi's charging station is on a level surface against a wall, with at least 3 feet (1 m) of space in front of it, and 2 feet (0.5 m) of space on its sides.
If after relocating the station bObi still can't seem to find it, you may need to sync the station. For detailed instructions on how to do this, see Syncing Charging Station.
