Frequently Asked Questions

Why does my iRobot keep getting Error 1?
Frequent Error 1 codes usually indicate your robot is getting stuck in the same areas repeatedly. Check for loose rug edges, furniture with low clearance, or areas where pet hair accumulates. Consider using virtual barriers to block problem areas.
Can I prevent iRobot Error 1 from happening?
Regular maintenance helps prevent this error. Clean the wheels weekly, remove small objects from floors before cleaning, and ensure rug edges are secured. Also check that furniture legs aren't positioned where they can trap the robot.
Is Error 1 dangerous for my iRobot vacuum?
Error 1 is not dangerous and is designed to protect your robot from damage. The robot stops moving when it detects the wheel issue to prevent motor strain or mechanical damage.
How often should I clean my iRobot wheels?
Clean the wheels weekly or whenever you notice decreased performance. Homes with pets or long-haired family members may need more frequent wheel cleaning to prevent hair buildup.
