iRobot Roomba 890 Troubleshooting

After the Roomba vacuums, dirt and filth is still left behind.

Check the main brush heads as hair can often get tangled in them and clog them. To get better access to the main brush head follow the first 6 steps of this guide and remove the hair.

The filter needs to be replaced approximately once every month or sooner depending on frequency of use. Follow the steps in this video to replace the filter.

The main brush heads can get damaged from regular use or improper installation. Follow the steps outlined in the Cleaning Head Replacement guide for how to replace damaged brushes.

The main brushes at the bottom of the Roomba do not rotate when the Roomba is cleaning.

Hair often gets tangled in the brushes and causes them to seize. By simply removing the brushes and cleaning out the hair, you can usually get it working again. To remove the brushes, follow this guide. Make sure to remove the end cap and remove the hair from each brush before reinstalling.

The brushes could have sustained damage from long term wear. You can purchase a new set of brushes and install them.

The Roomba will not charge when connected to the home base.

Make sure that the Home Base is plugged into an outlet and is on the floor in an area the Roomba can properly reach.

Check that the Roomba’s charging contacts are placed properly on the Home Base’s charging contacts. There should be a green light on the Home Base if the Roomba is properly connected. The Roomba should rest flat if placed correctly on the Home Base.

The battery in the Roomba may have been faulty or died from use. You’re going to want to replace it.

Parts: Battery

The Roomba can only recharge when it docks on the Home Base. If the Home Base is on a different level of the house, or separated by stairs or other obstacles, the Roomba won’t be able to return to charge. If there is something blocking the Home Base charging contacts, or the Home Base isn’t turned, on the Roomba won’t be able to charge at it either.

If the battery is losing charge unusually quickly after leaving the Home Base, or the battery doesn’t charge at all, then the battery has probably reached the end of its life.

The Roomba uses a r-con sensor to communicate with the Home Base. If the sensor is damaged it won’t be able to find the Home Base and can’t charge itself. Follow our guide on how to replace the IR sensor.

Roomba Drives in circles

The Roomba drives in circles as if a wall is in front of it.

Check to see if the bumper on the front of the robot is stuck and will no longer depress. Briskly tapping the bumper repeatedly should dislodge any debris jamming it up.

Check the condition of the Bumper Sensor and Cliff sensors located on the bottom of the robot. If they are covered in dirt, clean them off. After this process if the robot continues to drive in circles they may need to be replaced; luckily, we have a handy guide to show you how!

If the Roomba only appears to drive on one side, if it favors a counterclockwise or clockwise location, one of the drive wheel modules may be broken. Follow our guide on how to replace the Wheel Module here.
