Diagnosis: Failed navigation to Home Base due to dirty sensors, blocked path, or poor base placement.
FIX
- Clean the sensors. Wipe the front bumper sensor, cliff sensors, and the charging contacts on both the robot and the Home Base with a clean, dry cloth. Use a melamine foam pad for built-up debris.
- Ensure a clear path. The Home Base needs 4 ft (1.2 m) of clear space in front of it and 1.5 ft (0.5 m) on each side. Move furniture, toys, or cords.
- Check base placement. The Home Base must be on a level surface against a wall, and at least 4 ft (1.2 m) away from stairs to prevent falls.
- Manually return it. When the battery is low, press the Home button. A pulsing blue light ring indicates it's seeking the Home Base.
IF THAT DIDN'T WORK
- Check the power supply. Use only the provided power supply cord. Do not use a power converter or an unauthorized charger—this voids the warranty and can cause battery issues.
- Inspect the battery. The robot comes with a partial charge but needs 3 hours for a full charge before first use. For long-term storage, turn off the battery by removing the robot from the Home Base and holding the CLEAN button down for 10 seconds.
