Frequently Asked Questions

What can I do if Roomba's battery does not seem to be charging?

If Roomba's battery is not charging, you should first make sure it is properly seated in Roomba. When you insert the battery, you should hear two clicks. Then confirm that the green light on the charging “brick” is a solid green and that the power indicator light is pulsing. If Roomba is not charging on the Home Base, try charging Roomba by plugging the charger directly into the robot.. If this does not work, call customer service at 877-855-8593.

What should I do if Roomba repeatedly starts and stops, or just spins in place?

If Roomba is repeatedly starting and stopping, or just spinning in place, you may have a blocked cliff sensor.Try cleaning the cliff sensors, located under the bumper, with a Q-tip or compressed air.You also should remove and clean Roomba's brushes and brush bearings.

What can I do if Roomba is cleaning longer than I'd like in a particular room?

Roomba automatically calculates room size and run time based on a number of factors. Roomba will clean for longer in rooms with more debris and furniture. Roomba also spends a little bit longer cleaning rugs than hard floors. In an empty 8x10 room with hard floors, Roomba will clean for approximately 20 minutes. Removing obstacles from a room will decrease the amount of time Roomba needs to spend in a room.

What can I do to help Roomba get back to the Home Base?

The Home Base creates an infrared "beam" that Roomba needs to find in order to return success- fully. You should make sure that the Home Base is plugged in, the power light is on, and the base is on a flat, level surface. Do not use any Virtual Walls near the Home Base, the Virtual Walls use an infrared signal similar to that of the Home Base that may prevent Roomba from successfuly dock- ing. If you have a particularly large home, Roomba may have trouble finding the Home Base at the end of a cleaning cycle. If it does, try repositioning the Home Base.
