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.
Battery Life
Fully charge Scooba's battery (up to 4 hours) before each cleaning cycle.
When fully charged, Scooba's battery will always last longer than a full Clean
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.
16-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.
TIP: For best performance, always store Scooba's battery on a plugged-in charger.
Charge Scooba’s battery overnight for the first charge.

Scooba's Cleaning Pattern
Scooba's Cleaning Pattern
Scooba is a robot that cleans differently than the way most people clean
their floors. Scooba uses iRobot's AWARE™ Robot Intelligence System to
determine the best way to pass over and clean every section of the floor.
In most cases, Scooba will pass over the same area of the floor multiple
times to ensure a thorough cleaning. Scooba can clean rooms up to 200
square feet with a full tank, while larger rooms may require an additional
cleaning cycle.
Tip: For smaller rooms, pre-mix 1 measuring cup of Clorox® Scooba cleaning solution
with 1 quart of water. Partially filling the tank will shorten Scooba’s cleaning time.
While Scooba is cleaning it calculates the best path to clean your floor and
determines the best times to use its various cleaning behaviors:
Spiraling: Enables Scooba to efficiently clean a concentrated dirty area.
Wall following: Enables Scooba to clean the room perimeter and navigate
around furniture and obstacles.
Room Crossing: Enables Scooba to clean new areas while crisscrossing the room.
Light Sensing: Keeps Scooba from stopping in dark or hard-to-reach places.
Scooba will alternate
between spiraling, wall
following, and room crossing
during a cleaning cycle.
TIP: For best performance and floor coverage, clear your floor of chairs, clutter,
and light rugs. Use a Virtual Wall to contain Scooba to one room.
