storing Looj
Store iRobot Looj in a cool, dry place. After charging store Looj and its battery
between 50˚ and 80˚ F (10˚-26˚ C). Excessive heat or cold may reduce battery
life and product performance. For best results, we recommend removing both
the battery pack from the robot and the batteries from the remote control
handle when the product is stored.
