Cleaning
Your robot will automatically explore and clean your home in neat rows, avoiding obstacles using its front-facing camera. It will return to the charging station at the end of a cleaning job and whenever it needs to recharge.
Your robot is able to recognize and avoid objects. However, it is still recommended to remove excess clutter before cleaning.
- To end a job and send the robot back to its charging station, hold the clean button down for between 2-5 seconds. A blue light ring pattern will indicate that the robot is seeking the charging station.
- When your robot detects an especially dirty area, it will engage Dirt Detect™ mode, moving in a forwards/backward motion to clean the area more thoroughly. The light ring indicator will flash blue.
When the robot senses its bin needs to be emptied, the light ring indicator will illuminate in a red sweeping motion toward the rear.
