What To Do

should offer some resistance. If it does not, or if it's stuck
and you can't dislodge the obstruction, contact iRobot
customer care.
Inspect the right wheel. Spin the wheel by hand, the wheel
should offer some resistance. If it does not, or if it's stuck
and you can't dislodge the obstruction, contact iRobot

the battery and ensure it is fully seated and clicks into place.
Reconnect the power supply to the charging socket.

Clean cliff sensors with a cotton swab (see page 6 for
sensor location). The three cliff sensors are the black pieces
located behind the bumper and are accessed by turning the
Scooba over. Make sure the tanks are empty before turning
Scooba over.
Tap the bumper to ensure that it moves in and out. Visually
inspect bumper edges for debris.
Make sure Scooba was not recently filled with hot water or
charged in a hot place. Wait for Scooba and battery to cool
down and try again.
Inspect all wheels. Push the wheels up and down. Put the
robot back on the floor, press Clean.
Remove any obstacles from brushes and wheels. If problem
persists, contact iRobot customer care.
Ensure the front wheel can spin freely. Lightly push wheel up
and down. If material is stuck in the wheel, the front caster
wheel can be easily removed, cleaned and replaced. Put the
robot back on the floor, press Clean.
