Roborock Robot Vacuum Error Code 4: How to Fix It

Q: Why does my Roborock keep showing Error Code 4?

Error Code 4 typically appears when cliff sensors are dirty, blocked by debris, or damaged. Regular cleaning of the sensors and keeping the vacuum's environment free of excessive dust can prevent this error from recurring.

Q: How often should I clean the cliff sensors on my Roborock?

Clean the cliff sensors every 2-3 weeks or whenever you notice Error Code 4 appearing. If you have pets or a particularly dusty environment, you may need to clean them more frequently.

Q: Can I use my Roborock if the cliff sensors aren't working?

No, you should not use your Roborock with malfunctioning cliff sensors as it poses a safety risk. The vacuum could fall down stairs or off elevated surfaces, potentially causing damage to the unit or your home.

Q: What do Roborock cliff sensors actually do?

Cliff sensors use infrared technology to detect drop-offs like stairs, ledges, or other significant height changes. They prevent the vacuum from falling and getting damaged by stopping or redirecting the vacuum when a cliff is detected.

Q: Are Roborock cliff sensors covered under warranty?

Yes, cliff sensors are typically covered under Roborock's standard warranty if they fail due to manufacturing defects. However, damage from neglect, misuse, or normal wear and tear may not be covered.

Abstract

Roborock Error Code 4 indicates a cliff sensor malfunction, which prevents your robot vacuum from detecting stairs or drop-offs safely. This error typically occurs when the cliff sensors are dirty, blocked, or damaged, causing the vacuum to stop cleaning for safety reasons.
