What to do
Pick up Roomba, place it down securely on the floor and
touch the clean button to restart the cycle.
Turn over Roomba and remove the brush guard by pushing
the two yellow tabs. Remove the brushes, clear any
obstructions, and replace them again.
Turn over Roomba. Look to see if something is wrapped
around the side brush. Remove the side brush with a screw
driver and check for string or hair that may be wrapped
around it.
Remove and empty Roomba's bin.
Your Roomba may be stuck or something may be wrapped
around a wheel. Look for something wrapped around the
wheels. Push them in and out and make sure they turn
easily.
Turn over Roomba and clear any debris that might be
caught underneath the front bumper in the cliff sensors. You
can also use compressed air to clean them out.
Turn over Roomba and remove any obstructions that
prevent the wheels from seating all the way up into
Roomba's body. Also, remove any obstacles that Roomba
could drive over.
