Battery Performance
Scooba is powered by a rechargeable battery. Scooba’s 
battery will last for hundreds of cleaning cycles before 
needing replacement. 
Battery storage
For best battery performance, iRobot recommends storing Scooba’s battery in 
Scooba with the power supply plugged in. Do not store Scooba’s battery in the 
robot if the robot is not plugged in.
Battery life
Fully charge Scooba’s battery (up to 4 hours) before each cleaning cycle. 
When fully charged, Scooba’s battery will last for at least one full cleaning 
cycle. If you would like to run Scooba more frequently, you can purchase 
additional batteries and chargers at www.irobot.com. The battery should 
be replaced if Scooba cannot complete a cleaning cycle when fully charged.
1-Hour refresh Charge
Under some circumstances, Scooba uses a special 16-hour charge cycle 
to extend Scooba’s battery life. Scooba will use this charge cycle when the 
Scooba has been unplugged for an extended period of time or during the 
battery’s first charge. The Power light will rapidly blink green during this 
charging cycle.
 
TIP:  For best performance, always store scooba’s battery on a plugged-in charger. 
Charge scooba’s battery overnight for the first charge.
