Read enclosed safety information guide first before using your robot.

Position the dock

Position your dock on hard surface flooring, near an outlet, in an area with good WiFi® coverage.
Do not place it in direct sunlight.
Ensure the area around the dock is free of clutter to improve docking performance.

To prevent the risk of your robot falling down stairs, ensure that your dock is placed at least 4 feet (1.2 meters) away from stairs.

Install the dock ramp

Install the removable ramp by aligning with the dock.
Press down to snap into place.

Install the Pad Washing Roller

Remove stickers from Pad Washing Filter.
Install Pad Washing Roller from left to right by aligning the roller peg into place.

Prepare the Clean and Dirty tanks

Remove both tanks from the dock.
Fill the Clean Tank (left) with water or compatible cleaning solution.

Only certain cleaning solutions can be safely used with your robot. A full list of compatible cleaning solutions can be found on http://answers.irobot.com/s/roomba-combo-cleanser or by visiting the app. Please do not use other cleaning solutions or bleachbased products.
Both the Clean Tank and Dirty tank are shipped unlatched. You must latch both tanks before initial use.
Reinstall the tanks.

Ensure the latch is properly closed on the tank before reinstalling.

Plug in the dock

Plug the power cord into the dock, then into the wall.
Wrap the cord back so it won't get in the way of the robot as it comes and goes.

Wake up the robot

Place your robot on the dock with the camera facing out.
Make sure the metal charging contacts are lined up and the wheels are placed over the wheel switches.
The charging LED indicator on the dock will briefly illuminate when the robot is docked correctly.
After two full minutes your robot will chime when ready and display a solid or slowly filling white ring around its button.

information NOTE: Your robot comes with a partial charge, but we recommend that you charge the robot for 3 hours prior to starting the first cleaning job. If the light ring is swirling white, the robot is not ready and is still waking up.

The robot is unable to navigate in complete darkness. Turn on lights or open blinds to help the robot navigate.
You robot will return to the dock. You robot will return to the dock at the end of a cleaning job and whenever it needs to empty the bin, fill the water tank, wash the pad, or recharge. Once complete, it will resume the cleaning job where it left off.
Your robot is able to recognize and avoid objects. However, it is still recommended to remove excess obstacles before cleaning.

After 90 minutes of inactivity off the dock, the robot will automatically end its cleaning job. If you are unsure if the robot is finished or paused, visit the iRobot Home App to check on its status.

Dirt Detect™
When your robot detects an especially dirty area, it will engage Dirt Detect™ mode, moving in a forward/backward motion to clean the area more thoroughly.
The light ring indicator will flash blue when Dirt Detect™ mode is engaged.

Vacuuming
Starting a vaccum only cleaning job from your robot

Detach the mopping pad before starting a vacuum job.
Return the robot to the dock and press the Clean button on your robot.
